SNMPAgent Class
Properties Methods Events Config Settings Errors
The SNMPAgent class is used to implement UDP-based SNMP Agent Applications.
Syntax
class ipworkssnmp.SNMPAgent
Remarks
The SNMPAgent class implements a UDP-based standard SNMP Agent as specified in the SNMP RFCs. The class supports SNMP v1, v2c, and v3.
SNMP over DTLS is also supported when ssl_enabled is set to True. When acting as a client, the on_ssl_server_authentication event allows you to check the server identity and other security attributes. The on_ssl_status event provides information about the DTLS handshake. Additional SSL-related settings are also supported through the config method. When acting as a server, the SSLCert properties are used to select a certificate for the server. When client authentication is required, the ssl_authenticate_clients property can be set to True and the on_ssl_client_authentication event can be used to examine client credentials.
The class provides both encoding/decoding and transport capabilities, making the task of developing a custom SNMP agent as simple as setting a few key properties and handling a few events. SNMP data such as SNMP object id-s (OID-s) are exchanged as text strings, thus further simplifying the task of handling them.
The class is activated/deactivated by calling the activate or deactivate method. These methods enable or disable sending and receiving. The activation status can be found in the active property.
The class operates asynchronously. Requests are received through events such as on_get_request, on_get_bulk_request, on_get_next_request, etc. and the corresponding responses are automatically sent when the events return. Traps are sent through the send_trap method.
SNMPv3 USM security passwords are requested through the on_get_user_password event, and event parameters such as User and SecurityLevel provide information about the security attributes of received requests, and enable granular decision capability about what to provide and what not to provide. The send_secure_trap method is used to send authenticated (secure) SNMPv3 traps.
The add_user, remove_user, show_cache, and clear_cache methods are used to manage an internal authentication cache. This internal cache can be used as an alternative to the on_get_user_password event, automatically checking the cache against the security parameters provided in the request signature.
SNMP OIDs, types, and values are provided in the objects collection of SNMP objects for both sent and received packets.
Other packet information is provided through corresponding event parameters, such as Community, or RequestId.

accept_data Property
Enables or disables data reception.
Syntax
def get_accept_data() -> bool: ... def set_accept_data(value: bool) -> None: ...
accept_data = property(get_accept_data, set_accept_data)
Default Value
TRUE
Remarks
Setting the property to False temporarily disables data reception. Setting the property to True re-enables data reception.
active Property
Indicates whether the class is active.
Syntax
def get_active() -> bool: ... def set_active(value: bool) -> None: ...
active = property(get_active, set_active)
Default Value
FALSE
Remarks
This property indicates whether the class is currently active and can send or receive data.
The class will be automatically activated if it is not already and you attempt to perform an operation which requires the class to be active.
Use the activate and deactivate methods to control whether the class is active.
local_engine_id Property
The Engine Id of the SNMP Agent.
Syntax
def get_local_engine_id() -> bytes: ... def set_local_engine_id(value: bytes) -> None: ...
local_engine_id = property(get_local_engine_id, set_local_engine_id)
Default Value
""
Remarks
This property is only used for SNMPv3 packets (when snmp_version is 3).
local_host Property
This property includes the name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
def get_local_host() -> str: ... def set_local_host(value: str) -> None: ...
local_host = property(get_local_host, set_local_host)
Default Value
""
Remarks
The local_host 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 class initiate connections (or accept in the case of server classs) 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 class 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.
local_port Property
The port in the local host where the class listens.
Syntax
def get_local_port() -> int: ... def set_local_port(value: int) -> None: ...
local_port = property(get_local_port, set_local_port)
Default Value
161
Remarks
The local_port property must be set before the class is activated (active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine (default 161).
You may also set local_port to 0. This allows the TCP/IP stack to choose a port at random. The value chosen is provided via the local_port property after the class is activated through the active property.
local_port cannot be changed once the class is active. Any attempt to set the local_port property when the class is active will generate an error.
Note: on macOS and iOS, root permissions are required to set local_port to any value below 1024.
obj_count Property
The number of records in the Obj arrays.
Syntax
def get_obj_count() -> int: ... def set_obj_count(value: int) -> None: ...
obj_count = property(get_obj_count, set_obj_count)
Default Value
0
Remarks
This property controls the size of the following arrays:
The array indices start at 0 and end at obj_count - 1.obj_type Property
The current object's type.
Syntax
def get_obj_type(obj_index: int) -> int: ... def set_obj_type(obj_index: int, value: int) -> None: ...
Default Value

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 read-only.
ssl_server_cert_encoded Property
This is the certificate (PEM/Base64 encoded).
Syntax
def get_ssl_server_cert_encoded() -> bytes: ...
ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The ssl_server_cert_store and ssl_server_cert_subject properties also may be used to specify a certificate.
When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate. If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.
This property is read-only.
sys_up_time Property
Time passed since the agent was initialized (in hundredths of a second).
Syntax
def get_sys_up_time() -> int: ... def set_sys_up_time(value: int) -> None: ...
sys_up_time = property(get_sys_up_time, set_sys_up_time)
Default Value
0
Remarks
This property is used when sending SNMP traps, and it normally provides the time since the system was restarted in 1/100s of a second.
If another value is desired, you may set this property to a custom value. From that point on, sys_up_time will return the value set plus time elapsed.
activate Method
Activates the class.
Syntax
def activate() -> None: ...
Remarks
This method activates the component and will allow it to send or receive data.
The class will be automatically activated if it is not already and you attempt to perform an operation which requires the class to be active.
Note: Use the active property to check whether the component is active.
add_user Method
Adds a user to the internal authentication cache.
Syntax
def add_user(user: str, authentication_protocol: int, authentication_password: str, encryption_algorithm: int, encryption_password: str) -> None: ...
Remarks
The internal authentication cache can be used as an alternative to the on_get_user_password event, automatically checking the cache against the security parameters provided in the request signature.
The show_cache method is used to show the contents of the internal authentication cache.
The clear_cache method can be used to completely clear the cache.
Valid Authentication Protocols are:
HMAC-MD5-96 (1) | Message-Digest algorithm 5. |
HMAC-SHA-96 (2) | Secure Hash Algorithm. |
HMAC-192-SHA-256 (3) | Secure Hash Algorithm. |
HMAC-384-SHA-512 (4) | Secure Hash Algorithm. |
Valid Encryption Algorithms are:
DES (1) | Data Encryption Standard. |
AES (2) | Advanced Encryption Standard with key length of 128. |
3DES (3) | Triple Data Encryption Standard. |
AES192 (4) | Advanced Encryption Standard with key length of 192. |
AES256 (5) | Advanced Encryption Standard with key length of 256. |
NOTE: Specifying an authentication protocol of 0 is a special case where the class will attempt to verify users with all valid authentication protocols.
clear_cache Method
Clears the internal authentication database.
Syntax
def clear_cache() -> None: ...
Remarks
All user records are removed from the internal authentication cache as a result of this call.
config Method
Sets or retrieves a configuration setting.
Syntax
def config(configuration_string: str) -> str: ...
Remarks
config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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, you must call Config("PROPERTY"). The value will be returned as a string.
deactivate Method
Deactivates the class.
Syntax
def deactivate() -> None: ...
Remarks
This method deactivates the component and will prohibit it from sending and receiving data.
Note: Use the active property to check whether the component is active.
do_events Method
This method processes events from the internal message queue.
Syntax
def do_events() -> None: ...
Remarks
When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
hash_passwords Method
Hashes all passwords in the cache.
Syntax
def hash_passwords() -> None: ...
Remarks
Forces computation of all passwords hashes in the cache. Used together with the on_hash_password event to enable implementations of external password hash storage.
remove_user Method
Removes the user specified by User from the internal authentication cache.
Syntax
def remove_user(user: str) -> None: ...
Remarks
The internal authentication cache can be used as an alternative to the on_get_user_password event, automatically checking the cache against the security parameters provided in the request signature.
The show_cache method is used to show the contents of the internal authentication cache.
The clear_cache method can be used to completely clear the cache.
reset Method
Clears the object arrays.
Syntax
def reset() -> None: ...
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 will be reset to snmpverV2c (2).
send_response Method
Sends a response packet to a Get, Get-Next, Get-Bulk, or Set request.
Syntax
def send_response(remote_host: str, remote_port: int, request_id: int, community: str, error_status: int, error_index: int) -> None: ...
Remarks
Use this method to send asynchronous response packets. A valid RequestId must be specified. send_response sends an unauthenticated response packet. Depending upon the value of the snmp_version property, the packet is constructed as an SNMPv1, SNMPv2c, or SNMPv3 (unauthenticated) response PDU. To send authenticated or encrypted SNMPv3 responses, use send_secure_response
The RemoteHost and RemotePort parameters are used to determine where the response is to be sent. The object identifiers, types, and values for the request are taken from the objects collection. The RequestId, Community, ErrorStatus, and ErrorIndex parameters are used to specify other properties of the response.
send_secure_response Method
Sends an authenticated and/or encrypted SNMPv3 response.
Syntax
def send_secure_response(remote_host: str, remote_port: int, request_id: int, message_id: int, error_status: int, error_index: int, user: str, authentication_protocol: int, authentication_password: str, encryption_algorithm: int, encryption_password: str) -> None: ...
Remarks
Similar to the send_response method except that User, Authentication Protocol, and AuthenticationPassword are used to authenticate the response. EncryptionAlgorithm and EncryptionPassword (if not empty) are used to encrypt the response.
The MessageId argument must match the MessageId parameter obtained from the on_get_request, on_get_next_request, on_set_request, or on_get_bulk_request event.
The user and password arguments used to send the response will be added to the internal user cache. If the user is already in the cache, its passwords will be updated with those supplied.
Valid Authentication Protocols are:
HMAC-MD5-96 (1) | Message-Digest algorithm 5. |
HMAC-SHA-96 (2) | Secure Hash Algorithm. |
HMAC-192-SHA-256 (3) | Secure Hash Algorithm. |
HMAC-384-SHA-512 (4) | Secure Hash Algorithm. |

AES256 (5) | Advanced Encryption Standard with key length of 256. |
send_secure_trap Method
Sends an authenticated and/or encrypted SNMPv3 trap.
Syntax
def send_secure_trap(remote_host: str, trap_oid: str, user: str, authentication_protocol: int, authentication_password: str, encryption_algorithm: int, encryption_password: str) -> None: ...
Remarks
Similar to the send_trap method except that User, AuthenticationPassword, and Authentication Protocol are used to authenticate the trap. EncryptionPassword (if not empty) and EncryptionAlgorithm are used to encrypt the message.
The user and password arguments used to send the trap will be added to the internal user cache. If the user is already in the cache, its passwords will be updated with those supplied.
Valid Authentication Protocols are:
HMAC-MD5-96 (1) | Message-Digest algorithm 5. |
HMAC-SHA-96 (2) | Secure Hash Algorithm. |
HMAC-192-SHA-256 (3) | Secure Hash Algorithm. |

AES256 (5) | Advanced Encryption Standard with key length of 256. |
send_trap Method
Sends an SNMP Trap.
Syntax
def send_trap(remote_host: str, trap_oid: str) -> None: ...
Remarks
Depending upon the value of the snmp_version property, the packet is constructed as an SNMPv1 or SNMPv2 Trap PDU. The following configuration settings provide more control about how traps are generated: TrapPort, TrapAgentAddress, TrapCommunity, TrapEnterprise. The sys_up_time property provides the trap timestamp.
send_trap sends an unauthenticated trap. The send_secure_trap method is used to send authenticated SNMPv3 traps.
If any values are provided in the objects collection, they are sent unchanged. In the case of an SNMPv2 or SNMPv3 Trap, if objects has a count that is equal to 0, the following values are set: sysUpTime.0 equal to sys_up_time and snmpTrapOID.0 equal to TrapOID.
For SNMPv2 and SNMPv3 Traps, TrapOID must contain the full OID of the Trap. For SNMPv1, TrapOID must be a string of the form "generic.specific" where generic and specific are numeric values providing the Trap Generic Type and Specific Type.
For SNMPv1, TrapOID must be of the form "GenericTrap.SpecificTrap". These values are sent in the PDU header. TrapAgentAddress and TrapEnterprise are taken from the corresponding configuration settings.
Additionally, the following symbolic values are recognized and translated as follows:
Trap Name | OID (SNMPv2 and above) | SNMPv1 GenericType |
coldStart | 1.3.6.1.6.3.1.1.5.1 | 0 |
warmStart | 1.3.6.1.6.3.1.1.5.2 | 1 |
linkDown | 1.3.6.1.6.3.1.1.5.3 | 2 |
linkUp | 1.3.6.1.6.3.1.1.5.4 | 3 |
authenticationFailure | 1.3.6.1.6.3.1.1.5.5 | 4 |
egpNeighborLoss | 1.3.6.1.6.3.1.1.5.6 | 5 |
enterpriseSpecific | 1.3.6.1.6.3.1.1.5.7 | 6 |
show_cache Method
Lists all entries in the internal user authentication cache.
Syntax
def show_cache() -> None: ...
Remarks
A on_cache_entry event is fired for every record in the internal user authentication cache.
The internal authentication cache can be used as an alternative to the on_get_user_password event, automatically checking the cache against the security parameters provided in the request signature.
The show_cache method is used to show the contents of the internal authentication cache.
The clear_cache method can be used to completely clear the cache.
value Method
Returns the value corresponding to an OID.
Syntax
def value(oid: str) -> str: ...
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.
on_bad_packet Event
Fired for erroneous and/or malformed messages.
Syntax
class SNMPAgentBadPacketEventParams(object): @property def packet() -> bytes: ... @property def source_address() -> str: ... @property def source_port() -> int: ... @property def error_code() -> int: ... @property def error_description() -> str: ... @property def report() -> bool: ... @report.setter def report(value) -> None: ... # In class SNMPAgent: @property def on_bad_packet() -> Callable[[SNMPAgentBadPacketEventParams], None]: ... @on_bad_packet.setter def on_bad_packet(event_hook: Callable[[SNMPAgentBadPacketEventParams], None]) -> None: ...
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.
Please refer to the on_get_user_password event for more information concerning SNMPv3 authentication.
on_cache_entry Event
Shows in the internal cache.
Syntax
class SNMPAgentCacheEntryEventParams(object): @property def user() -> str: ... @property def authentication_protocol() -> str: ... @property def authentication_password() -> str: ... @property def encryption_algorithm() -> str: ... @property def encryption_password() -> str: ... # In class SNMPAgent: @property def on_cache_entry() -> Callable[[SNMPAgentCacheEntryEventParams], None]: ... @on_cache_entry.setter def on_cache_entry(event_hook: Callable[[SNMPAgentCacheEntryEventParams], None]) -> None: ...
Remarks
on_cache_entry events are triggered by a call to show_cache. One event is fired for each user.
on_connected Event
Fired immediately after a connection completes (or fails).
Syntax
class SNMPAgentConnectedEventParams(object): @property def remote_address() -> str: ... @property def remote_port() -> int: ... @property def status_code() -> int: ... @property def description() -> str: ... # In class SNMPAgent: @property def on_connected() -> Callable[[SNMPAgentConnectedEventParams], None]: ... @on_connected.setter def on_connected(event_hook: Callable[[SNMPAgentConnectedEventParams], None]) -> None: ...
Remarks
This event fires after a connection completes or fails.

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. 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_error Event

Syntax
class SNMPAgentErrorEventParams(object): @property def error_code() -> int: ... @property def description() -> str: ... # In class SNMPAgent: @property def on_error() -> Callable[[SNMPAgentErrorEventParams], None]: ... @on_error.setter def on_error(event_hook: Callable[[SNMPAgentErrorEventParams], None]) -> None: ...
Remarks
The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.
The ErrorCode 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 section.
on_get_bulk_request Event
Fired when a GetBulkRequest packet is received.
Syntax
class SNMPAgentGetBulkRequestEventParams(object): @property def request_id() -> int: ... @property def message_id() -> int: ... @property def snmp_version() -> int: ... @property def community() -> str: ... @property def user() -> str: ... @property def security_level() -> int: ... @property def source_address() -> str: ... @property def source_port() -> int: ... @property def non_repeaters() -> int: ... @property def max_repetitions() -> int: ... @property def error_index() -> int: ... @error_index.setter def error_index(value) -> None: ... @property def error_status() -> int: ... @error_status.setter def error_status(value) -> None: ... @property def error_description() -> str: ... @property def respond() -> bool: ... @respond.setter def respond(value) -> None: ... # In class SNMPAgent: @property def on_get_bulk_request() -> Callable[[SNMPAgentGetBulkRequestEventParams], None]: ... @on_get_bulk_request.setter def on_get_bulk_request(event_hook: Callable[[SNMPAgentGetBulkRequestEventParams], None]) -> None: ...
Remarks
This is only available for SNMP versions 2 and 3.
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_type, and obj_value 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. |
Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).
A GetBulkRequest is very similar to a GetNextRequest, the difference is that Getbulk performs a continuous GetNext operation based on the MaxRepitions 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 MaxRepitions 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 MaxRepitions. Thus the SNMPMgr is expecting to receive N + M x (X - N) objects, assuming that each object has M successors.
on_get_next_request Event
Fired when a GetNextRequest packet is received.
Syntax
class SNMPAgentGetNextRequestEventParams(object): @property def request_id() -> int: ... @property def message_id() -> int: ... @property def snmp_version() -> int: ... @property def community() -> str: ... @property def user() -> str: ... @property def security_level() -> int: ... @property def source_address() -> str: ... @property def source_port() -> int: ... @property def error_index() -> int: ... @error_index.setter def error_index(value) -> None: ... @property def error_status() -> int: ... @error_status.setter def error_status(value) -> None: ... @property def error_description() -> str: ... @property def respond() -> bool: ... @respond.setter def respond(value) -> None: ... # In class SNMPAgent: @property def on_get_next_request() -> Callable[[SNMPAgentGetNextRequestEventParams], None]: ... @on_get_next_request.setter def on_get_next_request(event_hook: Callable[[SNMPAgentGetNextRequestEventParams], None]) -> None: ...

If the password does not match the signature in the request, a on_bad_packet event will be fired, at which point you can decide whether to report the error to the client (see the description of the on_bad_packet event for more information).
If the User is invalid or unknown, set the password to empty string (default) to ignore the request. This will result in a on_bad_packet event being fired, at which point you can decide whether to report the error to the client or not.
on_get_user_security_level Event
Sets the security level for an incoming packet.
Syntax
class SNMPAgentGetUserSecurityLevelEventParams(object): @property def user() -> str: ... @property def engine_id() -> bytes: ... @property def security_level() -> int: ... @security_level.setter def security_level(value) -> None: ... # In class SNMPAgent: @property def on_get_user_security_level() -> Callable[[SNMPAgentGetUserSecurityLevelEventParams], None]: ... @on_get_user_security_level.setter def on_get_user_security_level(event_hook: Callable[[SNMPAgentGetUserSecurityLevelEventParams], None]) -> None: ...
Remarks
The on_get_user_security_level event is fired after the first inspection of each SNMPv3 request. The SecurityLevel parameter determines the level of security for the message.
On entry, the SecurityLevel parameter contains the default security level for User if the user is located in the internal cache, or if the User is not found in the cache, the SecurityLevel will be -1.
The value of SecurityLevel upon exiting the event, determines how the message will be processed:
-1 | The message will be ignored and a on_bad_packet event will be fired. |
0 | No security. The message will be processed without any authentication and/or encryption. |
1 | Authentication only. The message will be checked for a valid signature and the on_get_user_password event will be fired to verify the authentication password. |
2 | Authentication and Privacy. The message will be checked for a valid signature and the on_get_user_password event will be fired twice: first to verify the authentication password, and then to verify the privacy password. |
on_hash_password Event
Fired before and after a password is hashed.
Syntax
class SNMPAgentHashPasswordEventParams(object): @property def password() -> str: ... @property def auth_algorithm() -> int: ... @property def hash() -> str: ... @hash.setter def hash(value) -> None: ... # In class SNMPAgent: @property def on_hash_password() -> Callable[[SNMPAgentHashPasswordEventParams], None]: ... @on_hash_password.setter def on_hash_password(event_hook: Callable[[SNMPAgentHashPasswordEventParams], None]) -> None: ...
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 class 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_packet_trace Event
Fired for every packet sent or received.
Syntax
class SNMPAgentPacketTraceEventParams(object): @property def packet() -> bytes: ... @property def direction() -> int: ... @property def packet_address() -> str: ... @property def packet_port() -> int: ... # In class SNMPAgent: @property def on_packet_trace() -> Callable[[SNMPAgentPacketTraceEventParams], None]: ... @on_packet_trace.setter def on_packet_trace(event_hook: Callable[[SNMPAgentPacketTraceEventParams], None]) -> None: ...
Remarks
The on_packet_trace event shows all the packets sent or received by the class.
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
Fired when the class is ready to send data.
Syntax
class SNMPAgentReadyToSendEventParams(object): # In class SNMPAgent: @property def on_ready_to_send() -> Callable[[SNMPAgentReadyToSendEventParams], None]: ... @on_ready_to_send.setter def on_ready_to_send(event_hook: Callable[[SNMPAgentReadyToSendEventParams], None]) -> None: ...
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
Fired when a Report packet is received.
Syntax
class SNMPAgentReportEventParams(object): @property def request_id() -> int: ... @property def snmp_version() -> int: ... @property def community() -> str: ... @property def user() -> str: ... @property def security_level() -> int: ... @property def source_address() -> str: ... @property def source_port() -> int: ... @property def error_index() -> int: ... @property def error_status() -> int: ... @property def error_description() -> str: ... # In class SNMPAgent: @property def on_report() -> Callable[[SNMPAgentReportEventParams], None]: ... @on_report.setter def on_report(event_hook: Callable[[SNMPAgentReportEventParams], None]) -> None: ...
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_type, and obj_value 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_set_request Event
Fired when a SetRequest packet is received.
Syntax
class SNMPAgentSetRequestEventParams(object): @property def request_id() -> int: ... @property def message_id() -> int: ... @property def snmp_version() -> int: ... @property def community() -> str: ... @property def user() -> str: ... @property def security_level() -> int: ... @property def source_address() -> str: ... @property def source_port() -> int: ... @property def error_index() -> int: ... @error_index.setter def error_index(value) -> None: ... @property def error_status() -> int: ... @error_status.setter def error_status(value) -> None: ... @property def error_description() -> str: ... @property def respond() -> bool: ... @respond.setter def respond(value) -> None: ... # In class SNMPAgent: @property def on_set_request() -> Callable[[SNMPAgentSetRequestEventParams], None]: ... @on_set_request.setter def on_set_request(event_hook: Callable[[SNMPAgentSetRequestEventParams], None]) -> None: ...
Remarks
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_type, and obj_value 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. |
Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).
on_ssl_client_authentication Event
Fired when the client presents its credentials to the server.
Syntax
class SNMPAgentSSLClientAuthenticationEventParams(object): @property def remote_address() -> str: ... @property def remote_port() -> int: ... @property def cert_encoded() -> bytes: ... @property def cert_subject() -> str: ... @property def cert_issuer() -> str: ... @property def status() -> str: ... @property def accept() -> bool: ... @accept.setter def accept(value) -> None: ... # In class SNMPAgent: @property def on_ssl_client_authentication() -> Callable[[SNMPAgentSSLClientAuthenticationEventParams], None]: ... @on_ssl_client_authentication.setter def on_ssl_client_authentication(event_hook: Callable[[SNMPAgentSSLClientAuthenticationEventParams], None]) -> None: ...
Remarks
This event fires when a client connects to the class 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 stauts of the certificate.
Accept defines whether the certificate is accepted.
on_ssl_server_authentication Event
Fires when connecting to the server.
Syntax
class SNMPAgentSSLServerAuthenticationEventParams(object): @property def remote_address() -> str: ... @property def remote_port() -> int: ... @property def cert_encoded() -> bytes: ... @property def cert_subject() -> str: ... @property def cert_issuer() -> str: ... @property def status() -> str: ... @property def accept() -> bool: ... @accept.setter def accept(value) -> None: ... # In class SNMPAgent: @property def on_ssl_server_authentication() -> Callable[[SNMPAgentSSLServerAuthenticationEventParams], None]: ... @on_ssl_server_authentication.setter def on_ssl_server_authentication(event_hook: Callable[[SNMPAgentSSLServerAuthenticationEventParams], None]) -> None: ...
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 stauts of the certificate.
Accept defines whether the certificate is accepted.
on_ssl_status Event
Shows the progress of the secure connection.
Syntax
class SNMPAgentSSLStatusEventParams(object): @property def remote_address() -> str: ... @property def remote_port() -> int: ... @property def message() -> str: ... # In class SNMPAgent: @property def on_ssl_status() -> Callable[[SNMPAgentSSLStatusEventParams], None]: ... @on_ssl_status.setter def on_ssl_status(event_hook: Callable[[SNMPAgentSSLStatusEventParams], None]) -> None: ...
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.
SNMPAgent Config Settings
The class 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 class, access to these internal properties is provided through the config method.SNMPAgent Config Settings
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 or sending secure traps, you will need to select either 0 or 1. |
A valid port number (a value between 1 and 65535) is required. The default value is 162.
UDP Config Settings
The default value for this setting is False.
Note: This configuration setting is available only in Windows.
The default value is False.
Note: This configuration setting is available only in Windows.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the local_host 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).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by local_port after the connection is established.
local_port 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.
Note: This configuration setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later.
Note: This configuration setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above.
Note: QOSTrafficType must be set before setting active to True.
The default value for this setting is False.
Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).
Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).
The default value for this setting is False.
Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
