# Struct ipworkssnmp::SNMPTCPMgr The SNMPTCPMgr struct is used to implement TCP-based SNMP Management Applications. ## Syntax ```text ipworkssnmp::SNMPTCPMgr ``` ## Remarks The SNMPTCPMgr struct implements a TCP-based standard SNMP Manager as specified in the SNMP RFCs. The struct supports SNMP v1, v2c, and v3. The struct provides both encoding/decoding and transport capabilities, making the task of developing a custom SNMP manager as simple as setting a few key properties and handling a few events. SNMP data, such as for instance SNMP object id-s (OID-s) are exchanged as text strings, thus further simplifying the task of handling them. The struct is activated/deactivated by calling the [activate](#activate-method-snmptcpmgr-struct) or [deactivate](#deactivate-method-snmptcpmgr-struct) method. These methods enable or disable sending and receiving. The activation status can be found in the [active](#active-property-snmptcpmgr-struct) property. Messages are received through events such as [on_response](#on_response-event-snmptcpmgr-struct), [on_trap](#on_trap-event-snmptcpmgr-struct), or [on_inform_request](#on_inform_request-event-snmptcpmgr-struct). SNMP Traps are received through the [on_trap](#on_trap-event-snmptcpmgr-struct) event. Messages are sent to other agents or managers by using struct's methods such as [send_get_request](#send_get_request-method-snmptcpmgr-struct), [send_get_next_request](#send_get_next_request-method-snmptcpmgr-struct), [send_get_bulk_request](#send_get_bulk_request-method-snmptcpmgr-struct), [send_set_request](#send_set_request-method-snmptcpmgr-struct), and [send_inform_request](#send_inform_request-method-snmptcpmgr-struct). SNMP OIDs, types, and values are provided in the objects collection of SNMP objects for both sent and received packets. SNMPv3 USM security is enabled by setting properties such as [user](#user-property-snmptcpmgr-struct), [authentication_password](#authentication_password-property-snmptcpmgr-struct), and [encryption_password](#encryption_password-property-snmptcpmgr-struct) and calling the [discover](#discover-method-snmptcpmgr-struct) method to bind to a particular agent ([remote_engine_id](#remote_engine_id-property-snmptcpmgr-struct)). Upon successful discovery, received packets are checked for integrity (authentication) and timeliness. Note that the discovery step is optional, and may be avoided if the values for [remote_engine_id](#remote_engine_id-property-snmptcpmgr-struct), [remote_engine_boots](#remote_engine_boots-property-snmptcpmgr-struct), and [remote_engine_time](#remote_engine_time-property-snmptcpmgr-struct) are known in advance and provided to the struct through the respective properties. By default, the struct operates synchronously (except for the [discover](#discover-method-snmptcpmgr-struct) method), sending a request and waiting until the corresponding response has been received. This behavior may be overridden by setting [timeout](#timeout-property-snmptcpmgr-struct) to 0, in which case the struct returns control immediately after a send, and responses are received exclusively through the [on_response](#on_response-event-snmptcpmgr-struct) event. ### Object Lifetime The *new()* method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by IPWorksSNMP. Due to this, the SNMPTCPMgr struct cannot be disposed of automatically. Please, call the *dispose(&mut; self)* method of SNMPTCPMgr when you have finished using the instance. ## Property List *The following is the full list of the properties of the struct with short descriptions.

Setting the property to True re-enables data reception. This property is read-only. ## Data Type bool # active property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Indicates whether the struct is active. ## Syntax *Rust Syntax* ```text fn active(&self ) -> Result ``` ## Default Value false ## Remarks This property indicates whether the struct is currently active and can send or receive data. The struct will be automatically activated if it is not already and you attempt to perform an operation which requires the struct to be active. Use the [activate](#activate-method-snmptcpmgr-struct) and [deactivate](#deactivate-method-snmptcpmgr-struct) methods to control whether the struct is active. This property is read-only. ## Data Type bool # authentication_password property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The password used for SNMPv3 authentication. ## Syntax *Rust Syntax* ```text fn authentication_password(&self ) -> Result fn set_authentication_password(&self, value : &str) -> Option fn set_authentication_password_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks Every time [encryption_password](#encryption_password-property-snmptcpmgr-struct), authentication_password, or [remote_engine_id](#remote_engine_id-property-snmptcpmgr-struct) are set, a localized key is computed automatically, and cached internally. ## Data Type String # authentication_protocol property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The authentication protocol used for SNMPv3 packets. ## Syntax *Rust Syntax* ```text fn authentication_protocol(&self ) -> Result fn set_authentication_protocol(&self, value : i32) -> Option ``` ## Possible Values ```text 1 // HMACMD5962 // HMACSHA963 // HMAC192SHA2564 // HMAC384SHA5125 // HMAC128SHA2246 // HMAC256SHA384 ``` ## Default Value 1 ## Remarks This property defines the authentication protocol used when [snmp_version](#snmp_version-property-snmptcpmgr-struct) is set to snmpverV3. Possible values are: - 1 (HMAC-MD5-96 - default) - 2 (HMAC-SHA-96) - 3 (HMAC-192-SHA-256) - 4 (HMAC-384-SHA-512) - 5 (HMAC-128-SHA-224) - 6 (HMAC-256-SHA-384) ## Data Type i32 # community property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The community string used to authenticate SNMP packets. ## Syntax *Rust Syntax* ```text fn community(&self ) -> Result fn set_community(&self, value : &str) -> Option fn set_community_ref(&self, value : &String) -> Option ``` ## Default Value "public" ## Remarks Must match the community name that is specified on the agent. Typical values are "public" or "private". This property is used for all SNMP packets sent by the struct. ## Data Type String # encryption_algorithm property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The encryption algorithm used for SNMPv3 packets. ## Syntax *Rust Syntax* ```text fn encryption_algorithm(&self ) -> Result fn set_encryption_algorithm(&self, value : i32) -> Option ``` ## Possible Values ```text 1 // DES2 // AES3 // 3DES4 // AES1925 // AES256 ``` ## Default Value 1 ## Remarks In order to use encryption, you must set the [encryption_password](#encryption_password-property-snmptcpmgr-struct) property.

This property is read-only. ## Data Type String # error_index property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Index of the first variable (object) that caused an error from the last SNMP response. ## Syntax *Rust Syntax* ```text fn error_index(&self ) -> Result ``` ## Default Value 0 ## Remarks This property is used in conjunction with the [error_status](#error_status-property-snmptcpmgr-struct) property, and refers to the object that caused the error reported in the last SNMP response. This value is parsed directly from the SNMP response, which will be a one-based value, so a value of i here maps to index i-1 in the objects collection. The error_index property has no meaning when the [error_status](#error_status-property-snmptcpmgr-struct) property is 0 (no error). This property is read-only. ## Data Type i32 # error_status property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Status code for the last SNMP packet received by the struct. ## Syntax *Rust Syntax* ```text fn error_status(&self ) -> Result ``` ## Default Value 0 ## Remarks This property is used in conjunction with the [error_index](#error_index-property-snmptcpmgr-struct) property, which denotes the index of the variable in error. The [error_description](#error_description-property-snmptcpmgr-struct) property provides a textual description of the error. The following is a list of valid SNMP status code values: | | | | --- | --- | | 0 (noError) | No error. | | 1 (tooBig) | The response cannot fit in a single SNMP message. | | 2 (noSuchName) | Variable does not exist. | | 3 (badValue) | Invalid value or syntax. | | 4 (readOnly) | Variable is read-only. | | 5 (genError) | Other error (SNMPv1). | | 6 (noAccess) | Access denied. | | 7 (wrongType) | Wrong object type. | | 8 (wrongLength) | Wrong length. | | 9 (wrongEncoding) | Wrong encoding. | | 10 (wrongValue) | Wrong value. | | 11 (noCreation) | No creation. | | 12 (inconsistentValue) | Inconsistent value. | | 13 (resourceUnavailable) | Resource unavailable. | | 14 (commitFailed) | Commit failed. | | 15 (undoFailed) | Undo failed. | | 16 (authorizationError) | Authorization error. | | 17 (notWritable) | Variable is not writable. | | 18 (inconsistentName) | Inconsistent name. | The *ErrorIndex* parameter indicates the index of the first variable (object) that caused an error. The default value is 0. Variable indexes start with 0. *ErrorIndex* has no meaning when *ErrorStatus* is 0 (no error). The default value is 0 (no error). This property is read-only. ## Data Type i32 # local_engine_id property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The Engine Id of the SNMP Manager. ## Syntax *Rust Syntax* ```text fn local_engine_id(&self ) -> Result, IPWorksSNMPError> fn set_local_engine_id(&self, value : Vec) -> Option fn set_local_engine_id_ref(&self, value : &[u8]) -> Option ``` ## Default Value "" ## Remarks This property is only used for SNMPv3 packets (when [snmp_version](#snmp_version-property-snmptcpmgr-struct) is 3). ## Data Type Vec # local_host property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The name of the local host or user-assigned IP interface through which connections are initiated or accepted. ## Syntax *Rust Syntax* ```text fn local_host(&self ) -> Result fn set_local_host(&self, value : &str) -> Option fn set_local_host_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks This property contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address. In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the struct initiate connections (or accept in the case of server structs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used. If the struct is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface). NOTE: local_host is not persistent. You must always set it in code, and never in the property window. ## Data Type String # local_port property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The port in the local host where the SNMP Manager is bound to. ## Syntax *Rust Syntax* ```text fn local_port(&self ) -> Result fn set_local_port(&self, value : i32) -> Option ``` ## Default Value 0 ## Remarks The local_port property must be set before the struct is activated ([active](#active-property-snmptcpmgr-struct) is set to True). It instructs the struct to bind to a specific port (or communication endpoint) in the local machine. The default port is 0 (random port). If you would like to receive traps, set local_port to 162 (standard trap port). However, it is recommended that the [SNMPTrapMgr](SNMPTrapMgr.md#SNMPTrapMgr) struct be used for listening to traps, because [SNMPMgr](SNMPMgr.md#SNMPMgr) is limited to receiving SNMPv3 traps from a single agent only. [SNMPTrapMgr](SNMPTrapMgr.md#SNMPTrapMgr) does not have this limitation. local_port cannot be changed once the struct is [active](#active-property-snmptcpmgr-struct). Any attempt to set the local_port property when the struct is [active](#active-property-snmptcpmgr-struct) will generate an error. NOTE: on macOS and iOS, root permissions are required to set local_port to any value below 1024. ## Data Type i32 # obj_count property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The number of records in the Obj arrays. ## Syntax *Rust Syntax* ```text fn obj_count(&self ) -> Result fn set_obj_count(&self, value : i32) -> Option ``` ## Default Value 0 ## Remarks This property controls the size of the following arrays: - [obj_id](#obj_id-property-snmptcpmgr-struct) - [obj_type](#obj_type-property-snmptcpmgr-struct) - [obj_type_string](#obj_type_string-property-snmptcpmgr-struct) - [obj_value](#obj_value-property-snmptcpmgr-struct) The array indices start at *0* and end at *obj_count - 1*. ## Data Type i32 # obj_type property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The current object's type. ## Syntax *Rust Syntax* ```text fn obj_type(&self , ObjIndex : i32) -> Result fn set_obj_type(&self, ObjIndex : i32, value : i32) -> Option ``` ## Possible Values ```text 2 // Integer4 // OctetString5 // Null6 // ObjectId64 // IPAddress65 // Counter3266 // Gauge3267 // TimeTicks68 // Opaque69 // NSAP70 // Counter6471 // UnsignedInteger32128 // NoSuchObject129 // NoSuchInstance130 // EndOfMibView ``` ## Default Value 5 ## Remarks The current object's type. The default type is NULL (5). The corresponding object id and value are specified by the [obj_oid](#SNMPTCPMgr_p_ObjOid) and [obj_value](#obj_value-property-snmptcpmgr-struct) properties. Possible object type values include: | | | | --- | --- | | otInteger (2) | 2 | | otOctetString (4) | 4 | | otNull (5) | 5 | | otObjectID (6) | 6 | | otIPAddress (64) | 64 | | otCounter32 (65) | 65 | | otGauge32 (66) | 66 | | otTimeTicks (67) | 67 | | otOpaque (68) | 68 | | otNSAP (69) | 69 | | otCounter64 (70) | 70 | | otUnsignedInteger32 (71) | 71 | The struct also supports the following artificial object values used to designate error conditions: | | | | --- | --- | | otNoSuchObject (128) | No such object error. | | otNoSuchInstance (129) | No such instance error. | | otEndOfMibView (130) | End of MIB View error. | The *ObjIndex* parameter specifies the index of the item in the array.

The corresponding object id and type are specified by the [obj_oid](#SNMPTCPMgr_p_ObjOid) and [obj_object_type](#SNMPTCPMgr_p_ObjObjectType) properties. **Example** ```text SNMPControl.ObjCount = 1 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.ObjValue(0) = "New Value" ``` The *ObjIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [ObjCount](#obj_count-property-snmptcpmgr-struct) property. ## Data Type Vec # remote_engine_boots property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The remote engine boots (SNMPv3). ## Syntax *Rust Syntax* ```text fn remote_engine_boots(&self ) -> Result fn set_remote_engine_boots(&self, value : i32) -> Option ``` ## Default Value 0 ## Remarks This property is used in conjunction with the [remote_engine_time](#remote_engine_time-property-snmptcpmgr-struct) property. Please refer to the description of the [remote_engine_time](#remote_engine_time-property-snmptcpmgr-struct) property, and the [discover](#discover-method-snmptcpmgr-struct) method for further information. ## Data Type i32 # remote_engine_id property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The Engine Id of the remote agent. ## Syntax *Rust Syntax* ```text fn remote_engine_id(&self ) -> Result, IPWorksSNMPError> fn set_remote_engine_id(&self, value : Vec) -> Option fn set_remote_engine_id_ref(&self, value : &[u8]) -> Option ``` ## Default Value "" ## Remarks This property is only used for SNMPv3 packets (see [snmp_version](#snmp_version-property-snmptcpmgr-struct)), and is reset every time [remote_host](#remote_host-property-snmptcpmgr-struct) or [remote_port](#remote_port-property-snmptcpmgr-struct) changes. remote_engine_id is normally discovered through the [discover](#discover-method-snmptcpmgr-struct) method. However, by manually supplying a value for the property, remote_engine_id discovery step may be eliminated, thus avoiding the extra roundtrip to the agent ([remote_engine_boots](#remote_engine_boots-property-snmptcpmgr-struct) and [remote_engine_time](#remote_engine_time-property-snmptcpmgr-struct) are also required for [user](#user-property-snmptcpmgr-struct) authentication - please refer to the [discover](#discover-method-snmptcpmgr-struct) method for more information). ## Data Type Vec # remote_engine_time property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The remote engine time (SNMPv3). ## Syntax *Rust Syntax* ```text fn remote_engine_time(&self ) -> Result fn set_remote_engine_time(&self, value : i32) -> Option ``` ## Default Value 0 ## Remarks remote_engine_time is used by SNMPv3 authentication to ensure timeliness of requests, and avoid replay attacks.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject. If a matching certificate is found, the property is set to the full subject of the matching certificate. If an exact match is not found, the store is searched for subjects containing the value of the property. If a match is still not found, the property is set to an empty string, and no certificate is selected. The special value "*" picks a random certificate in the certificate store. The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows: | Field | Meaning | | --- | --- | | CN | Common Name. This is commonly a hostname like www.server.com. | | O | Organization | | OU | Organizational Unit | | L | Locality | | S | State | | C | Country | | E | Email Address | If a field value contains a comma, it must be quoted.

This property is used to assign a specific certificate. The [ssl_server_cert_store](#ssl_server_cert_store-property-snmptcpmgr-struct) and [ssl_server_cert_subject](#ssl_server_cert_subject-property-snmptcpmgr-struct) properties also may be used to specify a certificate. When [ssl_server_cert_encoded](#ssl_server_cert_encoded-property-snmptcpmgr-struct) is set, a search is initiated in the current [ssl_server_cert_store](#ssl_server_cert_store-property-snmptcpmgr-struct) for the private key of the certificate. If the key is found, [ssl_server_cert_subject](#ssl_server_cert_subject-property-snmptcpmgr-struct) is updated to reflect the full subject of the selected certificate; otherwise, [ssl_server_cert_subject](#ssl_server_cert_subject-property-snmptcpmgr-struct) is set to an empty string. This property is read-only. ## Data Type Vec # store_walk_objects property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Tells the struct whether or not to store returned objects. ## Syntax *Rust Syntax* ```text fn store_walk_objects(&self ) -> Result fn set_store_walk_objects(&self, value : bool) -> Option ``` ## Default Value true ## Remarks When a [walk](#walk-method-snmptcpmgr-struct) is performed, this property tells the struct whether or not to store the objects that are returned by the server in the objects collection. If the data is accumulated through the events, and not desired to be saved by the struct, set this property to false. ## Data Type bool # timeout property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) This property includes the timeout for the struct. ## Syntax *Rust Syntax* ```text fn timeout(&self ) -> Result fn set_timeout(&self, value : i32) -> Option ``` ## Default Value 60 ## Remarks If the timeout property is set to 0, all operations return immediately, potentially failing with a *WOULDBLOCK* error if data cannot be sent immediately. If timeout is set to a positive value, data is sent in a blocking manner and the struct will wait for the operation to complete before returning control. The struct will handle any potential *WOULDBLOCK* errors internally and automatically retry the operation for a maximum of timeout seconds. The struct will use [do_events](#do_events-method-snmptcpmgr-struct) to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive. If timeout expires, and the operation is not yet complete, the struct fails with an error. NOTE: By default, all timeouts are *inactivity timeouts*, that is, the timeout period is extended by timeout seconds when any amount of data is successfully sent or received. The default value for the timeout property is 60 seconds. ## Data Type i32 # user property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The user name used for SNMPv3 authentication. ## Syntax *Rust Syntax* ```text fn user(&self ) -> Result fn set_user(&self, value : &str) -> Option fn set_user_ref(&self, value : &String) -> Option ``` ## Default Value "" ## Remarks If authentication is desired, this property must be set before the struct attempts to connect to an SNMPv3 Agent. ## Data Type String # walk_limit property ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The limit of oid's returned in a walk. ## Syntax *Rust Syntax* ```text fn walk_limit(&self ) -> Result fn set_walk_limit(&self, value : i32) -> Option ``` ## Default Value 0 ## Remarks This property specifies the limit of how many oid's are to be traversed during an SNMP [walk](#walk-method-snmptcpmgr-struct). If set to 0, the struct will traverse all oid's in the specified table that are lexicographically greater than the value of the specified table oid. ## Data Type i32 # activate method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Activates the struct. ## Syntax *Rust Syntax* ```text fn activate(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks This method activates the component and will allow it to send or receive data. The struct will be automatically activated if it is not already and you attempt to perform an operation which requires the struct to be active. NOTE: Use the [active](#active-property-snmptcpmgr-struct) property to check whether the component is active. # config method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Sets or retrieves a configuration setting. ## Syntax *Rust Syntax* ```text fn config(&self, configuration_string : &str) -> Result ``` ## Remarks config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-snmptcpmgr-struct) for the struct. These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the config method. To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter). To read (query) the value of a [configuration setting](#config-settings-snmptcpmgr-struct), you must call *Config("PROPERTY")*. The value will be returned as a string. # deactivate method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Deactivates the struct. ## Syntax *Rust Syntax* ```text fn deactivate(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks This method deactivates the component and will prohibit it from sending and receiving data. NOTE: Use the [active](#active-property-snmptcpmgr-struct) property to check whether the component is active. # discover method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Performs SNMPv3 discovery. ## Syntax *Rust Syntax* ```text fn discover(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks When the method is called an SNMPv3 engine discovery request is sent to [remote_host](#remote_host-property-snmptcpmgr-struct). If an [authentication_password](#authentication_password-property-snmptcpmgr-struct) is provided, the engine id discovery request is followed by an engine time discovery request, as required by the SNMPv3 User Security Model (USM). In this case [timeout](#timeout-property-snmptcpmgr-struct) must be set to a non-zero value before calling **Discover** and the struct will wait until a response is received from [remote_host](#remote_host-property-snmptcpmgr-struct). The [on_discovery_response](#on_discovery_response-event-snmptcpmgr-struct) event is fired upon receipt of a valid discovery response and the values of [remote_engine_id](#remote_engine_id-property-snmptcpmgr-struct), [remote_engine_boots](#remote_engine_boots-property-snmptcpmgr-struct), and [remote_engine_time](#remote_engine_time-property-snmptcpmgr-struct) will then be updated with the received Engine Id, Time, and Boots. # do_events method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) This method processes events from the internal message queue. ## Syntax *Rust Syntax* ```text fn do_events(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks When do_events is called, the struct processes any available events. If no events are available, it waits for a preset period of time, and then returns. # hash_passwords method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Hashes all passwords in the cache. ## Syntax *Rust Syntax* ```text fn hash_passwords(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks Forces computation of all passwords hashes in the cache. Used together with the [on_hash_password](#on_hash_password-event-snmptcpmgr-struct) event to enable implementations of external password hash storage. # interrupt method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) This method interrupts the current method. ## Syntax *Rust Syntax* ```text fn interrupt(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks If there is no method in progress, interrupt simply returns, doing nothing. # reset method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Clears the object arrays. ## Syntax *Rust Syntax* ```text fn reset(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks Clears the object arrays, and sets the trap and error properties to their default values. This is useful for reinitializing all the properties that are used to create outgoing packets before building a new packet. Note: [snmp_version](#snmp_version-property-snmptcpmgr-struct) will be reset to **snmpverV2c (2)**. # send_get_bulk_request method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Send a GetBulkRequest packet. ## Syntax *Rust Syntax* ```text fn send_get_bulk_request(&self, non_repeaters : i32, max_repetitions : i32) -> Result<(), IPWorksSNMPError> ``` ## Remarks Sends a GetBulkRequest packet. This is only available for SNMP versions 2 and 3. *NonRepeaters* specifies the number of variables for which a single lexicographic successor is to be returned. *MaxRepetitions* specifies the number of lexicographic successors to be returned for variables other than those in the *NonRepeaters* list. The object identifiers, types, and values for the request are taken from the objects collection. A GetBulkRequest is very similar to a GetNextRequest, the difference is that Getbulk performs a continuous GetNext operation based on the *MaxRepetitions* value. The *NonRepeaters* value will determine the number of objects for which a simple GetNext operation should be performed. For the remaining variables, a continuous GetNext operation is performed based on the *MaxRepetitions* value. So if you send a request containing X objects, the agent will perform N simple GetNext operations and M continuous GetNext operations X - N times. With X being the number of objects received, N being the number of *NonRepeaters*, and M being the number of *MaxRepetitions*. Thus the SNMPMgr is expecting to receive N + M x (X - N) objects, assuming that each object has M successors. **Example (Sending a GetBulk Request)** ```text SNMPControl.RemoteHost = "MyAgent" SNMPControl.ObjCount = 2 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.objId(1) = "1.3.6.1.2.1.1.3.0" SNMPControl.SendGetBulkRequest(1,4) ``` The code sample above will send a GetBulkRequest with 1 non repeater, and a maxrepetitions of 4. Since there is only 1 non repeater, only one ObjID will "not repeat" and will only return one successor. The rest of the ObjID's (in this case, only 1) will return 4 successors. This particular example will return the following ObjID's: | | | | --- | --- | | 1 | 1.3.6.1.2.1.1.2.0 | | 2 | 1.3.6.1.2.1.1.4.0 | | 3 | 1.3.6.1.2.1.1.5.0 | | 4 | 1.3.6.1.2.1.1.6.0 | | 5 | 1.3.6.1.2.1.1.7.0 | # send_get_next_request method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Send GetNextRequest packet. ## Syntax *Rust Syntax* ```text fn send_get_next_request(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks Sends a GetNextRequest packet. The object identifiers, types, and values for the request are taken from the objects collection. **Example (Sending a GetNext Request)** ```text SNMPControl.ObjCount = 2 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.SendGetNextRequest() ``` The agent will respond with the "next" (relative to the ObjID(s) you specify) OID in the table. # send_get_request method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Send GetRequest packet. ## Syntax *Rust Syntax* ```text fn send_get_request(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks Sends a GetRequest packet. The object identifiers, types, and values for the request are taken from the objects collection. **Example (Sending a GetRequest)** ```text SNMPControl.RemoteHost = "MyAgent" SNMPControl.ObjCount = 2 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.ObjId(1) = "1.3.6.1.2.1.1.2.0" SNMPControl.SendGetRequest() ``` # send_inform_request method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Send an InformRequest packet. ## Syntax *Rust Syntax* ```text fn send_inform_request(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks Sends an InformRequest packet. The object identifiers, types, and values for the request are taken from the objects collection. # send_set_request method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Send Set Request packet. ## Syntax *Rust Syntax* ```text fn send_set_request(&self) -> Result<(), IPWorksSNMPError> ``` ## Remarks Sends a SetRequest packet. The object identifiers, types, and values for the request are taken from the objects collection. **Example (Sending a SetRequest)** ```text SNMPControl.RemoteHost = "MyAgent" SNMPControl.ObjCount = 1 SNMPControl.ObjId(0) = "1.3.6.1.2.1.1.1.0" SNMPControl.ObjValue(0) = "New Value" SNMPControl.ObjType(0) = otOctetString SNMPControl.SendSetRequest() ``` # value method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Returns the value corresponding to an OID. ## Syntax *Rust Syntax* ```text fn value(&self, oid : &str) -> Result ``` ## Remarks If the OID does not exist in the objects collection, a trappable error is generated. Please refer to the SNMPObject type for more information. # walk method ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Does an SNMP walk starting with the specified oid. ## Syntax *Rust Syntax* ```text fn walk(&self, table_oid : &str) -> Result<(), IPWorksSNMPError> ``` ## Remarks A walk will traverse all OIDs in the *TableOid* that are lexicographically greater than the value of the *TableOid*. The results of the walk may be obtained through the Response events. During the event, the current returned object will exist inside of the objects collection. If [store_walk_objects](#store_walk_objects-property-snmptcpmgr-struct) is set to true, the objects collection will contain all returned objects when the walk completes. Use the [walk_limit](#walk_limit-property-snmptcpmgr-struct) property to regulate how many objects the walk will traverse in the table. NOTE: The collection of objects is cleared before the walk begins. # on_bad_packet event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired for erroneous and/or malformed messages. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrBadPacketEventArgs carries the SNMPTCPMgr BadPacket event's parameters. pub struct SNMPTCPMgrBadPacketEventArgs { fn packet(&self) -> &[u8] fn source_address(&self) -> &String fn source_port(&self) -> i32 fn error_code(&self) -> i32 fn error_description(&self) -> &String fn report(&self) -> bool fn set_report(&self, value : bool) } // SNMPTCPMgrBadPacketEvent defines the signature of the SNMPTCPMgr BadPacket event's handler function. pub trait SNMPTCPMgrBadPacketEvent { fn on_bad_packet(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrBadPacketEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_bad_packet(&self) -> &'a dyn SNMPTCPMgrBadPacketEvent; pub fn set_on_bad_packet(&mut self, value : &'a dyn SNMPTCPMgrBadPacketEvent); ... } ``` ## Remarks The full message is provided in the *Packet* parameter. The on_bad_packet event is also fired when authentication fails for received packets due to a bad password or other reasons. If the *Report* parameter is set to True, an unauthenticated error report will be sent to the client, otherwise the packet will be silently ignored. # on_connected event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired immediately after a connection completes (or fails). ## Syntax *Rust Syntax* ```text // SNMPTCPMgrConnectedEventArgs carries the SNMPTCPMgr Connected event's parameters. pub struct SNMPTCPMgrConnectedEventArgs { fn remote_address(&self) -> &String fn remote_port(&self) -> i32 fn status_code(&self) -> i32 fn description(&self) -> &String } // SNMPTCPMgrConnectedEvent defines the signature of the SNMPTCPMgr Connected event's handler function. pub trait SNMPTCPMgrConnectedEvent { fn on_connected(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrConnectedEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_connected(&self) -> &'a dyn SNMPTCPMgrConnectedEvent; pub fn set_on_connected(&mut self, value : &'a dyn SNMPTCPMgrConnectedEvent); ... } ``` ## Remarks This event fires after a connection completes or fails. *StatusCode* is the value returned by the system TCP/IP stack.

This will be 0 if the connection was broken normally. *Description* contains a human readable description of the status. This will be "OK" if the connection was broken normally. *RemoteAddress* is the IP address of the remote host. *RemotePort* is the port on the remote host. # on_discovery_request event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when an SNMPv3 discovery packet is received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrDiscoveryRequestEventArgs carries the SNMPTCPMgr DiscoveryRequest event's parameters. pub struct SNMPTCPMgrDiscoveryRequestEventArgs { fn engine_id(&self) -> &[u8] fn engine_boots(&self) -> i32 fn engine_time(&self) -> i32 fn user(&self) -> &String fn security_level(&self) -> i32 fn source_address(&self) -> &String fn source_port(&self) -> i32 fn respond(&self) -> bool fn set_respond(&self, value : bool) } // SNMPTCPMgrDiscoveryRequestEvent defines the signature of the SNMPTCPMgr DiscoveryRequest event's handler function. pub trait SNMPTCPMgrDiscoveryRequestEvent { fn on_discovery_request(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrDiscoveryRequestEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_discovery_request(&self) -> &'a dyn SNMPTCPMgrDiscoveryRequestEvent; pub fn set_on_discovery_request(&mut self, value : &'a dyn SNMPTCPMgrDiscoveryRequestEvent); ... } ``` ## Remarks *EngineId*, *EngineBoots*, *EngineTime*, and *User* are the values received from *SourceAddress*. For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. *Respond* is True by default, and will automatically send a response using the value in [local_engine_id](#local_engine_id-property-snmptcpmgr-struct). To suppress the response, set *Respond* to False. The value returned to *SourceAddress* for *EngineBoots* is always 0, and *EngineTime* is the number of seconds since January 1st, 1970 (GMT). # on_discovery_response event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when an SNMPv3 discovery response is received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrDiscoveryResponseEventArgs carries the SNMPTCPMgr DiscoveryResponse event's parameters. pub struct SNMPTCPMgrDiscoveryResponseEventArgs { fn engine_id(&self) -> &[u8] fn engine_boots(&self) -> i32 fn engine_time(&self) -> i32 fn user(&self) -> &String fn security_level(&self) -> i32 fn source_address(&self) -> &String fn source_port(&self) -> i32 } // SNMPTCPMgrDiscoveryResponseEvent defines the signature of the SNMPTCPMgr DiscoveryResponse event's handler function. pub trait SNMPTCPMgrDiscoveryResponseEvent { fn on_discovery_response(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrDiscoveryResponseEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_discovery_response(&self) -> &'a dyn SNMPTCPMgrDiscoveryResponseEvent; pub fn set_on_discovery_response(&mut self, value : &'a dyn SNMPTCPMgrDiscoveryResponseEvent); ... } ``` ## Remarks *EngineId*, *EngineBoots*, *EngineTime*, and *User* are the values received from *SourceAddress* and *SourcePort*. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated request, *SecurityLevel* is at least 1. # on_error event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when information is available about errors during data delivery. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrErrorEventArgs carries the SNMPTCPMgr Error event's parameters. pub struct SNMPTCPMgrErrorEventArgs { fn error_code(&self) -> i32 fn description(&self) -> &String } // SNMPTCPMgrErrorEvent defines the signature of the SNMPTCPMgr Error event's handler function. pub trait SNMPTCPMgrErrorEvent { fn on_error(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrErrorEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_error(&self) -> &'a dyn SNMPTCPMgrErrorEvent; pub fn set_on_error(&mut self, value : &'a dyn SNMPTCPMgrErrorEvent); ... } ``` ## Remarks The on_error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error. The *error_code* parameter contains an error code, and the *description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-snmptcpmgr-struct) section. # on_hash_password event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired before and after a password is hashed. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrHashPasswordEventArgs carries the SNMPTCPMgr HashPassword event's parameters. pub struct SNMPTCPMgrHashPasswordEventArgs { fn password(&self) -> &String fn auth_algorithm(&self) -> i32 fn hash(&self) -> &String fn set_hash(&self, value : &str) fn set_hash_ref(&self, value : &String) } // SNMPTCPMgrHashPasswordEvent defines the signature of the SNMPTCPMgr HashPassword event's handler function. pub trait SNMPTCPMgrHashPasswordEvent { fn on_hash_password(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrHashPasswordEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_hash_password(&self) -> &'a dyn SNMPTCPMgrHashPasswordEvent; pub fn set_on_hash_password(&mut self, value : &'a dyn SNMPTCPMgrHashPasswordEvent); ... } ``` ## Remarks SNMPv3 passwords are hashed in order to obtain authentication and encryption keys. This is an expensive operation, and in certain situations it may be preferable to store the hashed passwords externally and supply them on demand. If a hash is required, the event fires with an empty string in the *Hash* parameter. In this case, you can choose to supply a value for the hash and stop the struct from computing the hash. The event also fires every time a hash is computed. In this case, the *Hash* parameter contains the value of the computed hash. *AuthAlgorithm* contains either 1 for HMAC-MD5-96, 2 for HMAC-SHA-96 or 3 for HMAC-192-SHA-256 # on_inform_request event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when an InformRequest packet is received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrInformRequestEventArgs carries the SNMPTCPMgr InformRequest event's parameters. pub struct SNMPTCPMgrInformRequestEventArgs { fn request_id(&self) -> i32 fn snmp_version(&self) -> i32 fn community(&self) -> &String fn user(&self) -> &String fn security_level(&self) -> i32 fn source_address(&self) -> &String fn source_port(&self) -> i32 fn error_index(&self) -> i32 fn set_error_index(&self, value : i32) fn error_status(&self) -> i32 fn set_error_status(&self, value : i32) fn error_description(&self) -> &String fn respond(&self) -> bool fn set_respond(&self, value : bool) } // SNMPTCPMgrInformRequestEvent defines the signature of the SNMPTCPMgr InformRequest event's handler function. pub trait SNMPTCPMgrInformRequestEvent { fn on_inform_request(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrInformRequestEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_inform_request(&self) -> &'a dyn SNMPTCPMgrInformRequestEvent; pub fn set_on_inform_request(&mut self, value : &'a dyn SNMPTCPMgrInformRequestEvent); ... } ``` ## Remarks The user in an InformRequest packet (SNMPv3) must match the user in the [user](#user-property-snmptcpmgr-struct) property. If not, the request is rejected, and a [on_bad_packet](#on_bad_packet-event-snmptcpmgr-struct) event is fired before on_inform_request is fired. The list of variables in the SNMP packet, including optional values and types, is provided through the objects collection. Each object is of type SNMPObject. This type describes the [obj_id](#obj_id-property-snmptcpmgr-struct), [obj_type](#obj_type-property-snmptcpmgr-struct), and [obj_value](#obj_value-property-snmptcpmgr-struct) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. The *MessageId* parameter identifies the received request. For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. To send a response, the *Respond* parameter must be set to true. By default, this value is false, which means no response will be sent. The *ErrorStatus* parameter may also be set to a valid SNMP status code (the default value is 0, which represents no error). The following is a list of valid SNMP status code values: | | | | --- | --- | | 0 (noError) | No error. | | 1 (tooBig) | The response cannot fit in a single SNMP message. | | 2 (noSuchName) | Variable does not exist. | | 3 (badValue) | Invalid value or syntax. | | 4 (readOnly) | Variable is read-only. | | 5 (genError) | Other error (SNMPv1). | | 6 (noAccess) | Access denied. | | 7 (wrongType) | Wrong object type. | | 8 (wrongLength) | Wrong length. | | 9 (wrongEncoding) | Wrong encoding. | | 10 (wrongValue) | Wrong value. | | 11 (noCreation) | No creation. | | 12 (inconsistentValue) | Inconsistent value. | | 13 (resourceUnavailable) | Resource unavailable. | | 14 (commitFailed) | Commit failed. | | 15 (undoFailed) | Undo failed. | | 16 (authorizationError) | Authorization error. | | 17 (notWritable) | Variable is not writable. | | 18 (inconsistentName) | Inconsistent name. | The *ErrorIndex* parameter indicates the index of the first variable (object) that caused an error. The default value is 0. Variable indexes start with 0. *ErrorIndex* has no meaning when *ErrorStatus* is 0 (no error). # on_packet_trace event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired for every packet sent or received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrPacketTraceEventArgs carries the SNMPTCPMgr PacketTrace event's parameters. pub struct SNMPTCPMgrPacketTraceEventArgs { fn packet(&self) -> &[u8] fn direction(&self) -> i32 fn packet_address(&self) -> &String fn packet_port(&self) -> i32 } // SNMPTCPMgrPacketTraceEvent defines the signature of the SNMPTCPMgr PacketTrace event's handler function. pub trait SNMPTCPMgrPacketTraceEvent { fn on_packet_trace(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrPacketTraceEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_packet_trace(&self) -> &'a dyn SNMPTCPMgrPacketTraceEvent; pub fn set_on_packet_trace(&mut self, value : &'a dyn SNMPTCPMgrPacketTraceEvent); ... } ``` ## Remarks The on_packet_trace event shows all the packets sent or received by the struct. *Packet* contains the full contents of the datagram. *Direction* shows the direction of the packet: 1 for incoming packets, and 2 for outgoing packets. In the case of an incoming packet, *PacketAddress* and *PacketPort* identify the source of the packet. In the case of an outgoing packet, *PacketAddress* and *PacketPort* identify the destination of the packet. # on_ready_to_send event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when the struct is ready to send data. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrReadyToSendEventArgs carries the SNMPTCPMgr ReadyToSend event's parameters. pub struct SNMPTCPMgrReadyToSendEventArgs { } // SNMPTCPMgrReadyToSendEvent defines the signature of the SNMPTCPMgr ReadyToSend event's handler function. pub trait SNMPTCPMgrReadyToSendEvent { fn on_ready_to_send(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrReadyToSendEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_ready_to_send(&self) -> &'a dyn SNMPTCPMgrReadyToSendEvent; pub fn set_on_ready_to_send(&mut self, value : &'a dyn SNMPTCPMgrReadyToSendEvent); ... } ``` ## Remarks The on_ready_to_send event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend(TBD. DataToSend is removed). # on_report event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when a Report packet is received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrReportEventArgs carries the SNMPTCPMgr Report event's parameters. pub struct SNMPTCPMgrReportEventArgs { fn request_id(&self) -> i32 fn snmp_version(&self) -> i32 fn community(&self) -> &String fn user(&self) -> &String fn security_level(&self) -> i32 fn source_address(&self) -> &String fn source_port(&self) -> i32 fn error_index(&self) -> i32 fn error_status(&self) -> i32 fn error_description(&self) -> &String } // SNMPTCPMgrReportEvent defines the signature of the SNMPTCPMgr Report event's handler function. pub trait SNMPTCPMgrReportEvent { fn on_report(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrReportEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_report(&self) -> &'a dyn SNMPTCPMgrReportEvent; pub fn set_on_report(&mut self, value : &'a dyn SNMPTCPMgrReportEvent); ... } ``` ## Remarks For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. The list of variables in the SNMP packet, including optional values and types, is provided through the objects collection. Each object is of type SNMPObject. This type describes the [obj_id](#obj_id-property-snmptcpmgr-struct), [obj_type](#obj_type-property-snmptcpmgr-struct), and [obj_value](#obj_value-property-snmptcpmgr-struct) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. # on_response event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when a GetResponse packet is received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrResponseEventArgs carries the SNMPTCPMgr Response event's parameters. pub struct SNMPTCPMgrResponseEventArgs { fn request_id(&self) -> i32 fn snmp_version(&self) -> i32 fn community(&self) -> &String fn user(&self) -> &String fn security_level(&self) -> i32 fn source_address(&self) -> &String fn source_port(&self) -> i32 fn error_index(&self) -> i32 fn error_status(&self) -> i32 fn error_description(&self) -> &String } // SNMPTCPMgrResponseEvent defines the signature of the SNMPTCPMgr Response event's handler function. pub trait SNMPTCPMgrResponseEvent { fn on_response(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrResponseEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_response(&self) -> &'a dyn SNMPTCPMgrResponseEvent; pub fn set_on_response(&mut self, value : &'a dyn SNMPTCPMgrResponseEvent); ... } ``` ## Remarks The *ErrorStatus* and *ErrorIndex* parameters contain information about possible errors. *ErrorDescription* is a textual description of *ErrorStatus*. This value is parsed directly from the SNMP response, which will be a one-based value, so a value of i here maps to index i-1 in the objects collection. The following is a list of valid SNMP status code values: | | | | --- | --- | | 0 (noError) | No error. | | 1 (tooBig) | The response cannot fit in a single SNMP message. | | 2 (noSuchName) | Variable does not exist. | | 3 (badValue) | Invalid value or syntax. | | 4 (readOnly) | Variable is read-only. | | 5 (genError) | Other error (SNMPv1). | | 6 (noAccess) | Access denied. | | 7 (wrongType) | Wrong object type. | | 8 (wrongLength) | Wrong length. | | 9 (wrongEncoding) | Wrong encoding. | | 10 (wrongValue) | Wrong value. | | 11 (noCreation) | No creation. | | 12 (inconsistentValue) | Inconsistent value. | | 13 (resourceUnavailable) | Resource unavailable. | | 14 (commitFailed) | Commit failed. | | 15 (undoFailed) | Undo failed. | | 16 (authorizationError) | Authorization error. | | 17 (notWritable) | Variable is not writable. | | 18 (inconsistentName) | Inconsistent name. | The *ErrorIndex* parameter indicates the index of the first variable (object) that caused an error. The default value is 0. Variable indexes start with 0. *ErrorIndex* has no meaning when *ErrorStatus* is 0 (no error). The list of variables in the SNMP packet, including optional values and types, is provided through the objects collection. Each object is of type SNMPObject. This type describes the [obj_id](#obj_id-property-snmptcpmgr-struct), [obj_type](#obj_type-property-snmptcpmgr-struct), and [obj_value](#obj_value-property-snmptcpmgr-struct) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. # on_ssl_client_authentication event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when the client presents its credentials to the server. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrSSLClientAuthenticationEventArgs carries the SNMPTCPMgr SSLClientAuthentication event's parameters. pub struct SNMPTCPMgrSSLClientAuthenticationEventArgs { fn remote_address(&self) -> &String fn remote_port(&self) -> i32 fn cert_encoded(&self) -> &[u8] fn cert_subject(&self) -> &String fn cert_issuer(&self) -> &String fn status(&self) -> &String fn accept(&self) -> bool fn set_accept(&self, value : bool) } // SNMPTCPMgrSSLClientAuthenticationEvent defines the signature of the SNMPTCPMgr SSLClientAuthentication event's handler function. pub trait SNMPTCPMgrSSLClientAuthenticationEvent { fn on_ssl_client_authentication(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrSSLClientAuthenticationEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_ssl_client_authentication(&self) -> &'a dyn SNMPTCPMgrSSLClientAuthenticationEvent; pub fn set_on_ssl_client_authentication(&mut self, value : &'a dyn SNMPTCPMgrSSLClientAuthenticationEvent); ... } ``` ## Remarks This event fires when a client connects to the struct and presents a certificate for authentication. The *Accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not. When *Accept* is False, *Status* shows why the verification failed (otherwise, *Status* contains the string "OK"). *RemoteAddress* is the IP address of the connecting client. *RemotePort* is the source port of the connecting client. *CertEncoded* is the base64 encoded certificate presented by the client. *CertSubject* is the subject of the certificate presented by the client. *CertIssuer* is the subject of the issuer of the certificate presented by the client. *Status* is the status of the certificate. *Accept* defines whether the certificate is accepted. # on_ssl_server_authentication event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fires when connecting to the server. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrSSLServerAuthenticationEventArgs carries the SNMPTCPMgr SSLServerAuthentication event's parameters. pub struct SNMPTCPMgrSSLServerAuthenticationEventArgs { fn remote_address(&self) -> &String fn remote_port(&self) -> i32 fn cert_encoded(&self) -> &[u8] fn cert_subject(&self) -> &String fn cert_issuer(&self) -> &String fn status(&self) -> &String fn accept(&self) -> bool fn set_accept(&self, value : bool) } // SNMPTCPMgrSSLServerAuthenticationEvent defines the signature of the SNMPTCPMgr SSLServerAuthentication event's handler function. pub trait SNMPTCPMgrSSLServerAuthenticationEvent { fn on_ssl_server_authentication(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrSSLServerAuthenticationEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_ssl_server_authentication(&self) -> &'a dyn SNMPTCPMgrSSLServerAuthenticationEvent; pub fn set_on_ssl_server_authentication(&mut self, value : &'a dyn SNMPTCPMgrSSLServerAuthenticationEvent); ... } ``` ## Remarks This event is where the client can decide whether to continue with the connection process or not. The *Accept* parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not. When *Accept* is False, *Status* shows why the verification failed (otherwise, *Status* contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the *Accept* parameter to True. *RemoteAddress* is the IP address of the server. *RemotePort* is the source port of the server. *CertEncoded* is the base64 encoded certificate presented by the server. *CertSubject* is the subject of the certificate presented by the server. *CertIssuer* is the subject of the issuer of the certificate presented by the server. *Status* is the status of the certificate. *Accept* defines whether the certificate is accepted. # on_ssl_status event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Shows the progress of the secure connection. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrSSLStatusEventArgs carries the SNMPTCPMgr SSLStatus event's parameters. pub struct SNMPTCPMgrSSLStatusEventArgs { fn remote_address(&self) -> &String fn remote_port(&self) -> i32 fn message(&self) -> &String } // SNMPTCPMgrSSLStatusEvent defines the signature of the SNMPTCPMgr SSLStatus event's handler function. pub trait SNMPTCPMgrSSLStatusEvent { fn on_ssl_status(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrSSLStatusEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_ssl_status(&self) -> &'a dyn SNMPTCPMgrSSLStatusEvent; pub fn set_on_ssl_status(&mut self, value : &'a dyn SNMPTCPMgrSSLStatusEvent); ... } ``` ## Remarks The event is fired for informational and logging purposes only. It is used to track the progress of the connection. *RemoteAddress* is the IP address of the remote machine. *RemotePort* is the port of the remote machine. *Message* is the log message. # on_trap event ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) Fired when a SNMP trap packet is received. ## Syntax *Rust Syntax* ```text // SNMPTCPMgrTrapEventArgs carries the SNMPTCPMgr Trap event's parameters. pub struct SNMPTCPMgrTrapEventArgs { fn request_id(&self) -> i32 fn snmp_version(&self) -> i32 fn community(&self) -> &String fn user(&self) -> &String fn security_level(&self) -> i32 fn trap_oid(&self) -> &String fn time_stamp(&self) -> i64 fn source_address(&self) -> &String fn source_port(&self) -> i32 } // SNMPTCPMgrTrapEvent defines the signature of the SNMPTCPMgr Trap event's handler function. pub trait SNMPTCPMgrTrapEvent { fn on_trap(&self, sender : SNMPTCPMgr, e : &mut SNMPTCPMgrTrapEventArgs); } impl <'a> SNMPTCPMgr<'a> { pub fn on_trap(&self) -> &'a dyn SNMPTCPMgrTrapEvent; pub fn set_on_trap(&mut self, value : &'a dyn SNMPTCPMgrTrapEvent); ... } ``` ## Remarks The **SNMPTrapMgr** struct should normally be used to receive traps, since it was designed and contains functionality specifically for that purpose. The SNMPMgr component can only receive traps from the agent that it is has most recently discovered with the [discover](#discover-method-snmptcpmgr-struct) method. The *TrapOID* and *TimeStamp* parameters contain the Trap OID and TimeStamp. In the case of an SNMPv1 trap, there are two possible scenarios: First, if the enterprise of the trap is "1.3.6.1.6.3.1.1.5", *TrapOID* will be a concatenation of TrapEnterprise and GenericTrap + 1. For instance a TrapOID of "1.3.6.1.6.3.1.1.5.5" has a TrapEnterprise of "1.3.6.1.6.3.1.1.5" and a GenericTrap of "4". Second, In all other cases *TrapOID* will be a concatenation of the values for TrapEnterprise, GenericTrap, and SpecificTrap, separated by '.'. For SNMPv2 and above, they are read from the variable-value list (if available). For SNMPv3, the *User* parameter shows the user that was supplied with the packet. This parameter *MUST* be used together with the *SecurityLevel* parameter which shows the level of security in the message. The *SecurityLevel* parameter shows whether the request has been authenticated. If *SecurityLevel* is 0, the request has *NOT* been authenticated (i.e. the packet signature has not been verified). For an authenticated, non encrypted request, *SecurityLevel* is 1. For an authenticated and encrypted request, *SecurityLevel* is 2. The SNMPMgr struct is limited to accepting authenticated traps only for the user specified in [user](#user-property-snmptcpmgr-struct) and password and from the engine specified in [remote_engine_id](#remote_engine_id-property-snmptcpmgr-struct) with time parameters in [remote_engine_boots](#remote_engine_boots-property-snmptcpmgr-struct) and [remote_engine_time](#remote_engine_time-property-snmptcpmgr-struct) (usually this is the SNMP engine discovered through the last call to [discover](#discover-method-snmptcpmgr-struct)). If authenticated traps come from a different engine, or for a different user, they are ignored, and a [on_bad_packet](#on_bad_packet-event-snmptcpmgr-struct) event is fired instead. The list of variables in the SNMP packet, including optional values and types, is provided through the objects collection. Each object is of type SNMPObject. This type describes the [obj_id](#obj_id-property-snmptcpmgr-struct), [obj_type](#obj_type-property-snmptcpmgr-struct), and [obj_value](#obj_value-property-snmptcpmgr-struct) of each SNMP object. These variables must be copied to another location before the event has completed executing, or they may be overridden by other events. The *SourceAddress* and *SourcePort* parameters show the address and port of the sender as reported by the TCP/IP stack. # Config Settings ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) The struct accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the [config](#config-method-snmptcpmgr-struct) method. ### SNMPTCPManager Config Settings **CheckMessageOrigin**: Whether to match the origin IP address when receiving responses.This setting specifies whether the struct matches the source IP address in the response to the destination IP address of the request. When True (default) the struct makes sure that response are received from the same IP to which the request was sent. In most cases this does not need to be changed. If there is a specific reason that responses are expected to originate from a different IP from that which the request was sent, this may be set to False. When False the struct will not check the origin of received responses. **CompatibilityMode**: Whether to operate the component in a specific compatibility mode.This setting will cause the component to operate in a manner different than normal so that it is compatible with third-party products and libraries. The following table lists the possible values for this setting: | | | | --- | --- | | 0 (default) | Component operates normally for greatest compatibility. | | 1 | Component uses SNMP4j-compatible encryption (AES192 and AES256). | | 2 | Component automatically detects whether to use SNMP4j-compatible encryption (AES192 and AES256). Note: This option is only applicable when receiving packets. If you are using [SNMPMgr](SNMPMgr.md#SNMPMgr) or sending secure traps, you will need to select either 0 or 1. | **ContextEngineId**: Sets the context engine id of the SNMP entity. If set, the context engine id included in the PDU will be set. **ContextName**: Sets the context name of the SNMP entity. If set, the context name included in the PDU will be set. **DecryptLogPackets**: Whether to decrypt logged packets.When set to *true* this setting will cause the struct to decrypt packets logged in [on_packet_trace](#on_packet_trace-event-snmptcpmgr-struct). This only applies when using SNMP Version 3. The default is *false*. **ForceLocalPort**: Forces the struct to bind to a specific port. The default value is True, which makes the struct throw an error if [local_port](#local_port-property-snmptcpmgr-struct) is busy. When [ForceLocalPort](#ForceLocalPort) is set to False and the port is busy, the struct silently chooses another random port. **IncomingContextEngineId**: The engine Id of the received packet.This setting holds the engine Id of the received packet. This may be queried at any time, including from within an event, and returns the engine Id of the received packet. This is not needed in most cases, but can be used to store the incoming engine Id to send an asynchronous response later. This value is read-only. **IncomingContextName**: The context name of the received packet.This setting holds the context name of the received packet. This may be queried at any time, including from within an event, and returns the context name of the received packet. This is not needed in most cases, but can be used to store the incoming context name to send an asynchronous response later. This value is read-only. **MsgMaxSize**: The maximum supported message size.This setting specifies the maximum supported message size in bytes. This is only applicable when [snmp_version](#snmp_version-property-snmptcpmgr-struct) is set to 3. This corresponds to the "msgMaxSize" field in the request. The default maximum message size is *16384* bytes. **SourceAddress**: The source address of the received packet.This setting holds the source address of the received packet. This may be queried at any time, including from within an event, and returns the source address of the received packet. This value is read-only. **SourcePort**: The source port of the received packet.This setting holds the source port of the received packet. This may be queried at any time, including from within an event, and returns the source port of the received packet. This value is read-only. **TimeoutInMilliseconds**: The timeout is treated as milliseconds.Setting **TimeoutInMilliseconds** to true causes the struct to use the value in [timeout](#timeout-property-snmptcpmgr-struct) as milliseconds instead of seconds, which is the default. **WalkInsideRange**: Stops the SNMP walk if the OID value returned from an agent is outside the table.When **WalkInsideRange** is set to true the Walk will continue only while the OID Values returned from the agent are greater than the current OID Value. If an object is returned with an OID value that is out of this range it is not added to the objects collection, the [on_error](#on_error-event-snmptcpmgr-struct) event will fire, and [walk](#walk-method-snmptcpmgr-struct) will return. The default value is true. **WalkStartOID**: Specifies the OID to be used when a Walk is performed.When this property is set and [walk](#walk-method-snmptcpmgr-struct) is called, the first request sent will contain the specified **WalkStartOID** value. This feature is particularly useful in the case of errors, such as timeouts, that may occur during a Walk. In such a case, you can set **WalkStartOID** to the last OID returned before the Timeout occurred then call [walk](#walk-method-snmptcpmgr-struct) again (using the original tableOID parameter value). This will allow you to continue the Walk where it left off (when the Timeout error occurred). Note that when [store_walk_objects](#store_walk_objects-property-snmptcpmgr-struct) is set to true and **WalkStartOID** is set, the existing entries in objects will be maintained when [walk](#walk-method-snmptcpmgr-struct) is called and new returned objects will be added (just as if no error occurred in the initial [walk](#walk-method-snmptcpmgr-struct) call). ### TCPClient Config Settings **ConnectionTimeout**: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the struct will use [timeout](#timeout-property-snmptcpmgr-struct) for establishing a connection and transmitting/receiving data. **EnableFallback**: **FallbackTimeout**: **FirewallAutoDetect**: Tells the struct whether or not to automatically detect and use firewall system settings, if available.This configuration setting is provided for use by structs that do not directly expose Firewall properties. **FirewallHost**: Name or IP address of firewall (optional).If a [FirewallHost](#FirewallHost) is given, requested connections will be authenticated through the specified firewall when connecting. If the [FirewallHost](#FirewallHost) setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the [FirewallHost](#FirewallHost) setting is set to the corresponding address. If the search is not successful, an error is returned. NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **FirewallHTTPVersion**: The HTTP version to be used when connecting through a tunneling proxy.When [FirewallType](#FirewallType) is set to a tunneling proxy, this setting dictates which HTTP version is used when connecting. **FirewallPassword**: Password to be used if authentication is to be used when connecting through the firewall.If [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the given firewall. If the authentication fails, the struct fails with an error. NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **FirewallPort**: The TCP port for the FirewallHost;.The [FirewallPort](#FirewallPort) is set automatically when [FirewallType](#FirewallType) is set to a valid value. NOTE: This configuration setting is provided for use by structs that do not directly expose Firewall properties. **FirewallType**: Determines the type of firewall to connect through.Possible values are as follows: | | | | --- | --- | | 0 | No firewall (default setting). | | 1 | Connect through a tunneling proxy. [FirewallPort](#FirewallPort) is set to 80. | | 2 | Connect through a SOCKS4 Proxy. [FirewallPort](#FirewallPort) is set to 1080. | | 3 | Connect through a SOCKS5 Proxy. [FirewallPort](#FirewallPort) is set to 1080. | | 10 | Connect through a SOCKS4A Proxy. [FirewallPort](#FirewallPort) is set to 1080. | NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **FirewallUser**: A user name if authentication is to be used connecting through a firewall.If the [FirewallHost](#FirewallHost) is specified, the [FirewallUser](#FirewallUser) and [FirewallPassword](#FirewallPassword) settings are used to connect and authenticate to the Firewall. If the authentication fails, the struct fails with an error. NOTE: This setting is provided for use by structs that do not directly expose Firewall properties. **KeepAliveInterval**: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by [KeepAliveTime](#KeepAliveTime). If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second. NOTE: This value is not applicable in macOS. **KeepAliveTime**: The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, [TCPKeepAlive](#TCPKeepAlive) will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds. **Linger**: When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True. In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if [LingerTime](#LingerTime) is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires. In the second scenario, if [LingerTime](#LingerTime) is a positive value, the system will attempt to send pending data until the specified [LingerTime](#LingerTime) is reached. If this attempt fails, then the system will reset the connection. The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the struct returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes). Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action. **LingerTime**: Time in seconds to have the connection linger. LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout. **LocalHost**: The name of the local host through which connections are initiated or accepted. The [local_host](#local_host-property-snmptcpmgr-struct) setting contains the name of the local host as obtained by the *gethostname()* system call, or if the user has assigned an IP address, the value of that address. In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the struct initiate connections (or accept in the case of server structs) only through that interface. If the struct is connected, the [local_host](#local_host-property-snmptcpmgr-struct) setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface). **LocalPort**: The port in the local host where the struct binds. This configuration setting must be set before a connection is attempted. It instructs the struct to bind to a specific port (or communication endpoint) in the local machine. Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by [local_port](#local_port-property-snmptcpmgr-struct) after the connection is established. [local_port](#local_port-property-snmptcpmgr-struct) cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems. **MaxLineLength**: The maximum amount of data to accumulate when no EOL is found.[MaxLineLength](#MaxLineLength) is the size of an internal buffer, which holds received data while waiting for an eol string. If an eol string is found in the input stream before [MaxLineLength](#MaxLineLength) bytes are received, the on_data_in event is fired with the *EOL* parameter set to True, and the buffer is reset. If no eol is found, and [MaxLineLength](#MaxLineLength) bytes are accumulated in the buffer, the on_data_in event is fired with the *EOL* parameter set to False, and the buffer is reset. The minimum value for [MaxLineLength](#MaxLineLength) is 256 bytes. The default value is 2048 bytes. **MaxTransferRate**: The transfer rate limit in bytes per second.This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit. **ProxyExceptionsList**: A semicolon separated list of hosts and IPs to bypass when using a proxy.This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance: *www.google.com;www.example.com* **TCPKeepAlive**: Determines whether or not the keep alive socket option is enabled.If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set [KeepAliveTime](#KeepAliveTime) and [KeepAliveInterval](#KeepAliveInterval) to configure the timing of the keep-alive packets. NOTE: This value is not applicable in Java. **TcpNoDelay**: Whether or not to delay when sending packets. When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm. By default, this configuration setting is set to False. **UseIPv6**: Whether to use IPv6.When set to *0* (default), the struct will use IPv4 exclusively. When set to *1*, the struct will use IPv6 exclusively. To instruct the struct to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to *2*. The default value is *0*. Possible values are as follows: | | | | --- | --- | | 0 | IPv4 only | | 1 | IPv6 only | | 2 | IPv6 with IPv4 fallback | **UseNTLMv2**: Whether to use NTLM V2.When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is True and NTLM V2 will be used. Set this to False to use NTLM V1. ### SSL Config Settings **LogSSLPackets**: Controls whether SSL packets are logged when using the internal security API.When ssl_provider is set to *Internal*, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is *False*, as it is useful only for debugging purposes. When enabled, SSL packet logs are output using the [on_ssl_status](#on_ssl_status-event-snmptcpmgr-struct) event, which will fire each time an SSL packet is sent or received. Enabling this configuration setting has no effect if ssl_provider is set to *Platform*. **OpenSSLCADir**: The path to a directory containing CA certificates.This functionality is available only when the provider is OpenSSL. The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. **OpenSSLCAFile**: Name of the file containing the list of CA's trusted by your application.This functionality is available only when the provider is OpenSSL. The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences: -----BEGIN CERTIFICATE----- ... (CA certificate in base64 encoding) ... -----END CERTIFICATE----- Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. **OpenSSLCipherList**: A string that controls the ciphers to be used by SSL.This functionality is available only when the provider is OpenSSL. The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH". **OpenSSLPrngSeedData**: The data to seed the pseudo random number generator (PRNG).This functionality is available only when the provider is OpenSSL. By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG. **ReuseSSLSession**: Determines if the SSL session is reused. If set to True, the struct will reuse the context if and only if the following criteria are met: - The target host name is the same. - The system cache entry has not expired (default timeout is 10 hours). - The application process that calls the function is the same. - The logon session is the same. - The instance of the struct is the same. **SSLCACerts**: A newline separated list of CA certificates to be included when performing an SSL handshake.When ssl_provider is set to *Internal*, this configuration setting specifies one or more CA certificates to be included with the ssl_cert property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance: ```text -----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert ... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE----- ``` **SSLCheckCRL**: Whether to check the Certificate Revocation List for the server certificate.This configuration setting specifies whether the struct will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the struct will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The struct will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the struct fails with an error. When set to 0 (default), the CRL check will not be performed by the struct. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported. This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems. **SSLCheckOCSP**: Whether to use OCSP to check the status of the server certificate.This configuration setting specifies whether the struct will use OCSP to check the validity of the server certificate. If set to 1 or 2, the struct will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The struct will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the struct fails with an error. When set to 0 (default), the struct will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported. This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems. **SSLCipherStrength**: The minimum cipher strength used for bulk encryption. This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated. NOTE: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the [on_ssl_status](#on_ssl_status-event-snmptcpmgr-struct) event. Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application. When the provider is OpenSSL, [SSLCipherStrength](#SSLCipherStrength) is currently not supported. This functionality is instead made available through the [OpenSSLCipherList](#OpenSSLCipherList) configuration setting. **SSLClientCACerts**: A newline separated list of CA certificates to use during SSL client certificate validation.This configuration setting is only applicable to server components (e.g., TCPServer) see [SSLServerCACerts](#SSLServerCACerts) for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when [ssl_authenticate_clients](#ssl_authenticate_clients-property-snmptcpmgr-struct) is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance: ```text -----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert ... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE----- ``` **SSLEnabledCipherSuites**: The cipher suite to be used in an SSL negotiation.This configuration setting enables the cipher suites to be used in SSL negotiation. By default, the enabled cipher suites will include all available ciphers ("*"). The special value "*" means that the struct will pick all of the supported cipher suites. If [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is set to any other value, only the specified cipher suites will be considered. Multiple cipher suites are separated by semicolons. Example values when ssl_provider is set to *Platform* include the following: ```text obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); ``` Possible values when ssl_provider is set to *Platform* include the following: - CALG_3DES - CALG_3DES_112 - CALG_AES - CALG_AES_128 - CALG_AES_192 - CALG_AES_256 - CALG_AGREEDKEY_ANY - CALG_CYLINK_MEK - CALG_DES - CALG_DESX - CALG_DH_EPHEM - CALG_DH_SF - CALG_DSS_SIGN - CALG_ECDH - CALG_ECDH_EPHEM - CALG_ECDSA - CALG_ECMQV - CALG_HASH_REPLACE_OWF - CALG_HUGHES_MD5 - CALG_HMAC - CALG_KEA_KEYX - CALG_MAC - CALG_MD2 - CALG_MD4 - CALG_MD5 - CALG_NO_SIGN - CALG_OID_INFO_CNG_ONLY - CALG_OID_INFO_PARAMETERS - CALG_PCT1_MASTER - CALG_RC2 - CALG_RC4 - CALG_RC5 - CALG_RSA_KEYX - CALG_RSA_SIGN - CALG_SCHANNEL_ENC_KEY - CALG_SCHANNEL_MAC_KEY - CALG_SCHANNEL_MASTER_HASH - CALG_SEAL - CALG_SHA - CALG_SHA1 - CALG_SHA_256 - CALG_SHA_384 - CALG_SHA_512 - CALG_SKIPJACK - CALG_SSL2_MASTER - CALG_SSL3_MASTER - CALG_SSL3_SHAMD5 - CALG_TEK - CALG_TLS1_MASTER - CALG_TLS1PRF Example values when ssl_provider is set to *Internal*include the following: ```text obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=TLS_DHE_DSS_WITH_AES_128_CBC_SHA"); obj.config("SSLEnabledCipherSuites=TLS_DHE_DSS_WITH_AES_128_CBC_SHA;TLS_ECDH_RSA_WITH_AES_128_CBC_SHA"); ``` Possible values when ssl_provider is set to *Internal* include the following: - TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 - TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 - TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384 - TLS_RSA_WITH_AES_256_GCM_SHA384 - TLS_RSA_WITH_AES_128_GCM_SHA256 - TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256 - TLS_DHE_DSS_WITH_AES_256_GCM_SHA384 - TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 - TLS_ECDH_RSA_WITH_AES_256_GCM_SHA384 - TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256 - TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 - TLS_DHE_DSS_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 - TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 - TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA384 - TLS_DHE_DSS_WITH_AES_256_CBC_SHA256 - TLS_RSA_WITH_AES_256_CBC_SHA256 - TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 - TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384 - TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 - TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 - TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 - TLS_RSA_WITH_AES_128_CBC_SHA256 - TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256 - TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256 - TLS_DHE_DSS_WITH_AES_128_CBC_SHA256 - TLS_RSA_WITH_AES_256_CBC_SHA - TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA - TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA - TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA - TLS_DHE_RSA_WITH_AES_256_CBC_SHA - TLS_ECDH_RSA_WITH_AES_256_CBC_SHA - TLS_DHE_DSS_WITH_AES_256_CBC_SHA - TLS_RSA_WITH_AES_128_CBC_SHA - TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA - TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA - TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA - TLS_ECDH_RSA_WITH_AES_128_CBC_SHA - TLS_DHE_RSA_WITH_AES_128_CBC_SHA - TLS_DHE_DSS_WITH_AES_128_CBC_SHA - TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA - TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA - TLS_ECDH_ECDSA_WITH_3DES_EDE_CBC_SHA - TLS_ECDH_RSA_WITH_3DES_EDE_CBC_SHA - TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA - TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA - TLS_RSA_WITH_3DES_EDE_CBC_SHA - TLS_RSA_WITH_DES_CBC_SHA - TLS_DHE_RSA_WITH_DES_CBC_SHA - TLS_DHE_DSS_WITH_DES_CBC_SHA - TLS_RSA_WITH_RC4_128_MD5 - TLS_RSA_WITH_RC4_128_SHA When TLS 1.3 is negotiated (see [SSLEnabledProtocols](#SSLEnabledProtocols)), only the following cipher suites are supported: - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 - TLS_AES_128_GCM_SHA256 [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) is used together with [SSLCipherStrength](#SSLCipherStrength). **SSLEnabledProtocols**: Used to enable/disable the supported security protocols.This configuration setting is used to enable or disable the supported security protocols. Not all supported protocols are enabled by default. The default value is *4032* for client components, and *3072* for server components. To specify a combination of enabled protocol versions set this config to the binary *OR* of one or more of the following values: | | | | --- | --- | | TLS1.3 | 12288 (Hex 3000) | | TLS1.2 | 3072 (Hex C00) (Default - Client and Server) | | TLS1.1 | 768 (Hex 300) (Default - Client) | | TLS1 | 192 (Hex C0) (Default - Client) | | SSL3 | 48 (Hex 30) | | SSL2 | 12 (Hex 0C) | Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases. **SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:** By default when TLS 1.3 is enabled, the struct will first try to use the platform TLS 1.3 implementation when the ssl_provider is set to Automatic for all editions. If the platform TLS 1.3 implementation is not available, the internal implementation will be used. In editions that are designed to run on Windows, ssl_provider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version. If set to *1* (Platform provider), please be aware of the following notes: - The platform provider is available only on Windows 11/Windows Server 2022 and up. - [SSLEnabledCipherSuites](#SSLEnabledCipherSuites) and other similar SSL configuration settings are not supported. - If [SSLEnabledProtocols](#SSLEnabledProtocols) includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions. **SSLEnabledProtocols: SSL2 and SSL3 Notes: ** SSL 2.0 and 3.0 are not supported by the struct when the ssl_provider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and ssl_provider needs to be set to platform. **SSLEnableRenegotiation**: Whether the renegotiation_info SSL extension is supported.This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is *false* by default, but it can be set to *true* to enable the extension. This configuration setting is applicable only when ssl_provider is set to *Internal*. **SSLIncludeCertChain**: Whether the entire certificate chain is included in the SSLServerAuthentication event.This configuration setting specifies whether the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-snmptcpmgr-struct) event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-snmptcpmgr-struct) event. If set to True, all certificates returned by the server will be present in the Encoded parameter of the [on_ssl_server_authentication](#on_ssl_server_authentication-event-snmptcpmgr-struct) event. This includes the leaf certificate, any intermediate certificate, and the root certificate. **SSLKeyLogFile**: The location of a file where per-session secrets are written for debugging purposes.This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes. When set, the struct will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the struct will only append, it will not overwrite previous values. NOTE: This configuration setting is applicable only when ssl_provider is set to *Internal*. **SSLNegotiatedCipher**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedCipher[connId]"); ``` **SSLNegotiatedCipherStrength**: Returns the negotiated cipher suite strength.This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedCipherStrength[connId]"); ``` **SSLNegotiatedCipherSuite**: Returns the negotiated cipher suite.This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedCipherSuite[connId]"); ``` **SSLNegotiatedKeyExchange**: Returns the negotiated key exchange algorithm.This configuration setting returns the key exchange algorithm negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedKeyExchange[connId]"); ``` **SSLNegotiatedKeyExchangeStrength**: Returns the negotiated key exchange algorithm strength.This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedKeyExchangeStrength[connId]"); ``` **SSLNegotiatedVersion**: Returns the negotiated protocol version.This configuration setting returns the protocol version negotiated during the SSL handshake. NOTE: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: ```csharp server.Config("SSLNegotiatedVersion[connId]"); ``` **SSLSecurityFlags**: Flags that control certificate verification.The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions: | | | | --- | --- | | 0x00000001 | Ignore time validity status of certificate. | | 0x00000002 | Ignore time validity status of CTL. | | 0x00000004 | Ignore non-nested certificate times. | | 0x00000010 | Allow unknown certificate authority. | | 0x00000020 | Ignore wrong certificate usage. | | 0x00000100 | Ignore unknown certificate revocation status. | | 0x00000200 | Ignore unknown CTL signer revocation status. | | 0x00000400 | Ignore unknown certificate authority revocation status. | | 0x00000800 | Ignore unknown root revocation status. | | 0x00008000 | Allow test root certificate. | | 0x00004000 | Trust test root certificate. | | 0x80000000 | Ignore non-matching CN (certificate CN non-matching server name). | This functionality is currently not available when the provider is OpenSSL. **SSLServerCACerts**: A newline separated list of CA certificates to use during SSL server certificate validation.This configuration setting is only used by client components (e.g., TCPClient) see [SSLClientCACerts](#SSLClientCACerts) for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance: ```text -----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE----- ``` **TLS12SignatureAlgorithms**: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.This configuration setting specifies the allowed server certificate signature algorithms when ssl_provider is set to *Internal* and [SSLEnabledProtocols](#SSLEnabledProtocols) is set to allow TLS 1.2. When specified the struct will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the struct fails with an error. The format of this value is a comma-separated list of hash-signature combinations. For instance: ```csharp component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); ``` The default value for this configuration setting is *sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa*. To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent. **TLS12SupportedGroups**: The supported groups for ECC.This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC. The default value is *ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1*. When using TLS 1.2 and ssl_provider is set to *Internal*, the values refer to the supported groups for ECC. The following values are supported: - "ecdhe_secp256r1" (default) - "ecdhe_secp384r1" (default) - "ecdhe_secp521r1" (default) **TLS13KeyShareGroups**: The groups for which to pregenerate key shares.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server. The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting. NOTE: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group. In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so. The default value is *ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072* The values are ordered from most preferred to least preferred. The following values are supported: - "ecdhe_x25519" (default) - "ecdhe_x448" - "ecdhe_secp256r1" (default) - "ecdhe_secp384r1" (default) - "ecdhe_secp521r1" - "ffdhe_2048" (default) - "ffdhe_3072" (default) - "ffdhe_4096" - "ffdhe_6144" - "ffdhe_8192" **TLS13SignatureAlgorithms**: The allowed certificate signature algorithms.This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following: - "ed25519" (default) - "ed448" (default) - "ecdsa_secp256r1_sha256" (default) - "ecdsa_secp384r1_sha384" (default) - "ecdsa_secp521r1_sha512" (default) - "rsa_pkcs1_sha256" (default) - "rsa_pkcs1_sha384" (default) - "rsa_pkcs1_sha512" (default) - "rsa_pss_sha256" (default) - "rsa_pss_sha384" (default) - "rsa_pss_sha512" (default) The default value is *rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448*. This configuration setting is applicable only when [SSLEnabledProtocols](#SSLEnabledProtocols) includes TLS 1.3. **TLS13SupportedGroups**: The supported groups for (EC)DHE key exchange.This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so. The default value is *ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192,mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768* The values are ordered from most preferred to least preferred. The following values are supported: - "ecdhe_x25519" (default) - "ecdhe_x448" (default) - "ecdhe_secp256r1" (default) - "ecdhe_secp384r1" (default) - "ecdhe_secp521r1" (default) - "ffdhe_2048" (default) - "ffdhe_3072" (default) - "ffdhe_4096" (default) - "ffdhe_6144" (default) - "ffdhe_8192" (default) - "mlkem_512" (default) - "mlkem_768" (default) - "mlkem_1024" (default) - "x25519_mlkem_768" (default) - "secp256r1_mlkem_768" (default) Post-quantum algorithms (*mlkem_512,mlkem_768,mlkem_1024,x25519_mlkem_768,secp256r1_mlkem_768*) in our components rely on the operating system's underlying cryptographic primitives. The following platforms are currently supported: - Windows Server 2025 - Windows 11 24H2 - Windows 11 25H2 ### Socket Config Settings **AbsoluteTimeout**: Determines whether timeouts are inactivity timeouts or absolute timeouts.If [AbsoluteTimeout](#AbsoluteTimeout) is set to True, any method that does not complete within [timeout](#timeout-property-snmptcpmgr-struct) seconds will be aborted. By default, *AbsoluteTimeout* is False, and the timeout is an inactivity timeout. NOTE: This option is not valid for User Datagram Protocol (UDP) ports. **FirewallData**: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes). **InBufferSize**: The size in bytes of the incoming queue of the socket.This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the *InBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the struct is activated the *InBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. **OutBufferSize**: The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the *OutBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the struct is activated the *OutBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. ### Base Config Settings **BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build. **CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

It will return the following information: - Product: The product the license is for. - Product Key: The key the license was generated from. - License Source: Where the license was found (e.g., RuntimeLicense, License File). - License Type: The type of license installed (e.g., Royalty Free, Single Server). - Last Valid Build: The last valid build number for which the license will work. **MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the struct will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the struct to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section. # Trappable Errors ([SNMPTCPMgr](#struct-ipworkssnmpsnmptcpmgr) Struct) ### SNMPTCPMgr Errors | | | | --- | --- | | 201 | Timeout. | | 301 | Bad Object Index when accessing the Obj* properties.
