The SNMPTCPMgr class is used to implement TCP-based SNMP Management Applications.

Syntax

SNMPTCPMgr

Remarks

The SNMPTCPMgr class implements a TCP-based standard SNMP Manager as specified in the SNMP RFCs. The class supports SNMP v1, v2c, and v3.

The class 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 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.

Messages are received through events such as Response, Trap, or InformRequest. SNMP Traps are received through the Trap event.

Messages are sent to other agents or managers by using class's methods such as SendGetRequest, SendGetNextRequest, SendGetBulkRequest, SendSetRequest, and SendInformRequest.

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, AuthenticationPassword, and EncryptionPassword and calling the Discover method to bind to a particular agent (RemoteEngineId). 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 RemoteEngineId, RemoteEngineBoots, and RemoteEngineTime are known in advance and provided to the class through the respective properties.

By default, the class operates synchronously (except for the Discover method), sending a request and waiting until the corresponding response has been received. This behavior may be overridden by setting Timeout to 0, in which case the class returns control immediately after a send, and responses are received exclusively through the Response event.

Data Type

Binary String

LocalHost Property (SNMPTCPMgr Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);

int ipworkssnmp_snmptcpmgr_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

Default Value

""

Remarks

The LocalHost 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 multi-homed 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 LocalHost 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 multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (SNMPTCPMgr Class)

The port in the local host where the SNMP Manager is bound to.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)

int SetLocalPort(int iLocalPort);

Unicode (Windows)
INT GetLocalPort();
INT SetLocalPort(INT iLocalPort);

int ipworkssnmp_snmptcpmgr_getlocalport(void* lpObj);
int ipworkssnmp_snmptcpmgr_setlocalport(void* lpObj, int iLocalPort);

int GetLocalPort();
int SetLocalPort(int iLocalPort);

Default Value

0

Remarks

The LocalPort 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. The default port is 0 (random port). If you would like to receive traps, set LocalPort to 162 (standard trap port). However, it is recommended that the SNMPTrapMgr class be used for listening to traps, because SNMPMgr is limited to receiving SNMPv3 traps from a single agent only. SNMPTrapMgr does not have this limitation.

LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.

Note: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024.

Data Type

Integer

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

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=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

Data Type

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)
INT GetSSLServerCertEncoded(LPSTR &lpSSLServerCertEncoded, INT &lenSSLServerCertEncoded);

int ipworkssnmp_snmptcpmgr_getsslservercertencoded(void* lpObj, char** lpSSLServerCertEncoded, int* lenSSLServerCertEncoded);

QByteArray GetSSLServerCertEncoded();

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Binary String

StoreWalkObjects Property (SNMPTCPMgr Class)

Tells the class whether or not to store returned objects.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetStoreWalkObjects();
int SetStoreWalkObjects(int bStoreWalkObjects);

Unicode (Windows)
BOOL GetStoreWalkObjects();
INT SetStoreWalkObjects(BOOL bStoreWalkObjects);

int ipworkssnmp_snmptcpmgr_getstorewalkobjects(void* lpObj);
int ipworkssnmp_snmptcpmgr_setstorewalkobjects(void* lpObj, int bStoreWalkObjects);

bool GetStoreWalkObjects();
int SetStoreWalkObjects(bool bStoreWalkObjects);

Default Value

TRUE

Remarks

When a Walk is performed, this property tells the class 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 class, set this property to false.

Data Type

Boolean

Timeout Property (SNMPTCPMgr Class)

A timeout for the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int ipworkssnmp_snmptcpmgr_gettimeout(void* lpObj);
int ipworkssnmp_snmptcpmgr_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

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 class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

The class will use DoEvents 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 class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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

Integer

User Property (SNMPTCPMgr Class)

The user name used for SNMPv3 authentication.

Syntax

int ipworkssnmp_snmptcpmgr_setwalklimit(void* lpObj, int iWalkLimit);

int GetWalkLimit();
int SetWalkLimit(int iWalkLimit);

Default Value

0

Remarks

Data Type

Integer

Activate Method (SNMPTCPMgr Class)

Activates the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Activate();

Unicode (Windows)
INT Activate();

int ipworkssnmp_snmptcpmgr_activate(void* lpObj);

int Activate();

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (SNMPTCPMgr Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworkssnmp_snmptcpmgr_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Deactivate Method (SNMPTCPMgr Class)

Deactivates the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Deactivate();

Unicode (Windows)
INT Deactivate();

int ipworkssnmp_snmptcpmgr_deactivate(void* lpObj);

int Deactivate();

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Discover Method (SNMPTCPMgr Class)

Performs SNMPv3 discovery.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Discover();

Unicode (Windows)
INT Discover();

int ipworkssnmp_snmptcpmgr_discover(void* lpObj);

int Discover();

Remarks

When the method is called an SNMPv3 engine discovery request is sent to RemoteHost.

If an AuthenticationPassword 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 must be set to a non-zero value before calling Discover and the class will wait until a response is received from RemoteHost.

The DiscoveryResponse event is fired upon receipt of a valid discovery response and the values of RemoteEngineId, RemoteEngineBoots, and RemoteEngineTime will then be updated with the received Engine Id, Time, and Boots.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

• C++
• C
• Qt

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();

int ipworkssnmp_snmptcpmgr_doevents(void* lpObj);

int DoEvents();

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

HashPasswords Method (SNMPTCPMgr Class)

Hashes all passwords in the cache.

Syntax

• C
• Qt

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int ipworkssnmp_snmptcpmgr_reset(void* lpObj);

int Reset();

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: SNMPVersion will be reset to snmpverV2c (2).

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SendGetBulkRequest Method (SNMPTCPMgr Class)

Send a GetBulkRequest packet.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SendGetBulkRequest(int iNonRepeaters, int iMaxRepetitions);

Unicode (Windows)
INT SendGetBulkRequest(INT iNonRepeaters, INT iMaxRepetitions);

int ipworkssnmp_snmptcpmgr_sendgetbulkrequest(void* lpObj, int iNonRepeaters, int iMaxRepetitions);

int SendGetBulkRequest(int iNonRepeaters, int iMaxRepetitions);

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 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.

Example (Sending a GetBulk Request)

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:

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

virtual int FireBadPacket(SNMPTCPMgrBadPacketEventParams *e) {...}

Remarks

The full message is provided in the Packet parameter.

The BadPacket 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.

Connected Event (SNMPTCPMgr Class)

Fired immediately after a connection completes (or fails).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireConnected(SNMPTCPMgrConnectedEventParams *e);

  int SecurityLevel();

  const QString &SourceAddress();

  int SourcePort();

  bool Respond();
  void SetRespond(bool bRespond);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void DiscoveryRequest(SNMPTCPMgrDiscoveryRequestEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireDiscoveryRequest(SNMPTCPMgrDiscoveryRequestEventParams *e) {...}

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 LocalEngineId. 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).

DiscoveryResponse Event (SNMPTCPMgr Class)

Fired when an SNMPv3 discovery response is received.

  const QString &User();

  int SecurityLevel();

  const QString &SourceAddress();

  int SourcePort();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void DiscoveryResponse(SNMPTCPMgrDiscoveryResponseEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireDiscoveryResponse(SNMPTCPMgrDiscoveryResponseEventParams *e) {...}

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.

Error Event (SNMPTCPMgr Class)

Fired when information is available about errors during data delivery.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(SNMPTCPMgrErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} SNMPTCPMgrErrorEventParams;


Unicode (Windows)
virtual INT FireError(SNMPTCPMgrErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} SNMPTCPMgrErrorEventParams;

#define EID_SNMPTCPMGR_ERROR 7

virtual INT IPWORKSSNMP_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class SNMPTCPMgrErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(SNMPTCPMgrErrorEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireError(SNMPTCPMgrErrorEventParams *e) {...}

Remarks

The 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.

HashPassword Event (SNMPTCPMgr Class)

Fired before and after a password is hashed.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireHashPassword(SNMPTCPMgrHashPasswordEventParams *e);

typedef struct {
  const char *Password;
  int AuthAlgorithm;
  char *Hash;
  int reserved;
} SNMPTCPMgrHashPasswordEventParams;


Unicode (Windows)
virtual INT FireHashPassword(SNMPTCPMgrHashPasswordEventParams *e);

typedef struct {
  LPCWSTR Password;
  INT AuthAlgorithm;
  LPWSTR Hash;
  INT reserved;
} SNMPTCPMgrHashPasswordEventParams;

#define EID_SNMPTCPMGR_HASHPASSWORD 8

virtual INT IPWORKSSNMP_CALL FireHashPassword(LPSTR &lpszPassword, INT &iAuthAlgorithm, LPSTR &lpszHash);

class SNMPTCPMgrHashPasswordEventParams {
public:
  const QString &Password();

  int AuthAlgorithm();

  const QString &Hash();
  void SetHash(const QString &qsHash);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void HashPassword(SNMPTCPMgrHashPasswordEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireHashPassword(SNMPTCPMgrHashPasswordEventParams *e) {...}

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

InformRequest Event (SNMPTCPMgr Class)

Fired when an InformRequest packet is received.

#define EID_SNMPTCPMGR_INFORMREQUEST 9

virtual INT IPWORKSSNMP_CALL FireInformRequest(INT &iRequestId, INT &iSNMPVersion, LPSTR &lpszCommunity, LPSTR &lpszUser, INT &iSecurityLevel, LPSTR &lpszSourceAddress, INT &iSourcePort, INT &iErrorIndex, INT &iErrorStatus, LPSTR &lpszErrorDescription, BOOL &bRespond);

class SNMPTCPMgrInformRequestEventParams {
public:
  int RequestId();

  int SNMPVersion();

  const QString &Community();

  const QString &User();

  int SecurityLevel();

  const QString &SourceAddress();

  int SourcePort();

  int ErrorIndex();
  void SetErrorIndex(int iErrorIndex);

  int ErrorStatus();
  void SetErrorStatus(int iErrorStatus);

  const QString &ErrorDescription();

  bool Respond();
  void SetRespond(bool bRespond);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void InformRequest(SNMPTCPMgrInformRequestEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireInformRequest(SNMPTCPMgrInformRequestEventParams *e) {...}

Remarks

The user in an InformRequest packet (SNMPv3) must match the user in the User property. If not, the request is rejected, and a BadPacket event is fired before InformRequest 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 ObjId, ObjType, and ObjValue 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:

Variable indexes start with 0. ErrorIndex has no meaning when ErrorStatus is 0 (no error).

PacketTrace Event (SNMPTCPMgr Class)

Fired for every packet sent or received.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FirePacketTrace(SNMPTCPMgrPacketTraceEventParams *e);

  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void PacketTrace(SNMPTCPMgrPacketTraceEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FirePacketTrace(SNMPTCPMgrPacketTraceEventParams *e) {...}

Remarks

The PacketTrace 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.

ReadyToSend Event (SNMPTCPMgr Class)

Fired when the class is ready to send data.

Syntax

void ReadyToSend(SNMPTCPMgrReadyToSendEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireReadyToSend(SNMPTCPMgrReadyToSendEventParams *e) {...}

Remarks

The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend.

Report Event (SNMPTCPMgr Class)

Fired when a Report packet is received.

Syntax

  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Report(SNMPTCPMgrReportEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireReport(SNMPTCPMgrReportEventParams *e) {...}

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 ObjId, ObjType, and ObjValue 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.

Response Event (SNMPTCPMgr Class)

Fired when a GetResponse packet is received.

Syntax

void Response(SNMPTCPMgrResponseEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireResponse(SNMPTCPMgrResponseEventParams *e) {...}

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:

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 ObjId, ObjType, and ObjValue 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.

SSLClientAuthentication Event (SNMPTCPMgr Class)

Fired when the client presents its credentials to the server.

  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} SNMPTCPMgrSSLClientAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLClientAuthentication(SNMPTCPMgrSSLClientAuthenticationEventParams *e);

typedef struct {
  LPCWSTR RemoteAddress;

  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} SNMPTCPMgrSSLClientAuthenticationEventParams;

#define EID_SNMPTCPMGR_SSLCLIENTAUTHENTICATION 14

virtual INT IPWORKSSNMP_CALL FireSSLClientAuthentication(LPSTR &lpszRemoteAddress, INT &iRemotePort, LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class SNMPTCPMgrSSLClientAuthenticationEventParams {
public:
  const QString &RemoteAddress();

  int RemotePort();

  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLClientAuthentication(SNMPTCPMgrSSLClientAuthenticationEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireSSLClientAuthentication(SNMPTCPMgrSSLClientAuthenticationEventParams *e) {...}

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.

SSLServerAuthentication Event (SNMPTCPMgr Class)

Fires when connecting to the server.

} SNMPTCPMgrSSLServerAuthenticationEventParams;

#define EID_SNMPTCPMGR_SSLSERVERAUTHENTICATION 15

virtual INT IPWORKSSNMP_CALL FireSSLServerAuthentication(LPSTR &lpszRemoteAddress, INT &iRemotePort, LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class SNMPTCPMgrSSLServerAuthenticationEventParams {
public:
  const QString &RemoteAddress();

  int RemotePort();

  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLServerAuthentication(SNMPTCPMgrSSLServerAuthenticationEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireSSLServerAuthentication(SNMPTCPMgrSSLServerAuthenticationEventParams *e) {...}

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.

SSLStatus Event (SNMPTCPMgr Class)

Shows the progress of the secure connection.

Syntax

void Trap(SNMPTCPMgrTrapEventParams *e);

// Or, subclass SNMPTCPMgr and override this emitter function.
virtual int FireTrap(SNMPTCPMgrTrapEventParams *e) {...}

Remarks

The SNMPTrapMgr class 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 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 class is limited to accepting authenticated traps only for the user specified in User and Password and from the engine specified in RemoteEngineId with time parameters in RemoteEngineBoots and RemoteEngineTime (usually this is the SNMP engine discovered through the last call to Discover). If authenticated traps come from a different engine, or for a different user, they are ignored, and a BadPacket 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 ObjId, ObjType, and ObjValue 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.
