The SNMPTCPAgent class is used to implement TCP-based SNMP Agent Applications.

Syntax

SNMPTCPAgent

Remarks

The SNMPTCPAgent class implements a TCP-based standard SNMP Agent 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 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 GetRequest, GetBulkRequest, GetNextRequest, etc. and the corresponding responses are automatically sent when the events return. Traps are sent through the SendTrap method.

SNMPv3 USM security passwords are requested through the GetUserPassword 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 SendSecureTrap method is used to send authenticated (secure) SNMPv3 traps.

The AddUser, RemoveUser, ShowCache, and ClearCache methods are used to manage an internal authentication cache. This internal cache can be used as an alternative to the GetUserPassword 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.

AcceptData Property (SNMPTCPAgent Class)

Enables or disables data reception.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetAcceptData();
int SetAcceptData(int bAcceptData);

Unicode (Windows)
BOOL GetAcceptData();
INT SetAcceptData(BOOL bAcceptData);

int ipworkssnmp_snmptcpagent_getacceptdata(void* lpObj);
int ipworkssnmp_snmptcpagent_setacceptdata(void* lpObj, int bAcceptData);

bool GetAcceptData();
int SetAcceptData(bool bAcceptData);

Default Value

TRUE

Remarks

Setting the property to False temporarily disables data reception. Setting the property to True re-enables data reception.

This property is not available at design time.

Data Type

Boolean

Active Property (SNMPTCPAgent Class)

Indicates whether the class is active.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetActive();
int SetActive(int bActive);

Unicode (Windows)
BOOL GetActive();
INT SetActive(BOOL bActive);

int ipworkssnmp_snmptcpagent_getactive(void* lpObj);
int ipworkssnmp_snmptcpagent_setactive(void* lpObj, int bActive);

bool GetActive();
int SetActive(bool bActive);

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.

This property is not available at design time.

Data Type

Boolean

LocalEngineId Property (SNMPTCPAgent Class)

The Engine Id of the SNMP Agent.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetLocalEngineId(char* &lpLocalEngineId, int &lenLocalEngineId);
int SetLocalEngineId(const char* lpLocalEngineId, int lenLocalEngineId);

Unicode (Windows)
INT GetLocalEngineId(LPSTR &lpLocalEngineId, INT &lenLocalEngineId);
INT SetLocalEngineId(LPCSTR lpLocalEngineId, INT lenLocalEngineId);

int ipworkssnmp_snmptcpagent_getlocalengineid(void* lpObj, char** lpLocalEngineId, int* lenLocalEngineId);
int ipworkssnmp_snmptcpagent_setlocalengineid(void* lpObj, const char* lpLocalEngineId, int lenLocalEngineId);

QByteArray GetLocalEngineId();
int SetLocalEngineId(QByteArray qbaLocalEngineId);

Default Value

""

Remarks

This property is only used for SNMPv3 packets (when SNMPVersion is 3).

Data Type

Binary String

LocalHost Property (SNMPTCPAgent 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);

char* ipworkssnmp_snmptcpagent_getlocalhost(void* lpObj);
int ipworkssnmp_snmptcpagent_setlocalhost(void* lpObj, const char* lpszLocalHost);

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

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 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 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 multihomed 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 (SNMPTCPAgent Class)

The port in the local host where the class listens.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetLocalPort();
int SetLocalPort(int iLocalPort);

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

int ipworkssnmp_snmptcpagent_getlocalport(void* lpObj);
int ipworkssnmp_snmptcpagent_setlocalport(void* lpObj, int iLocalPort);

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

Default Value

161

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 (default 161).

You may also set LocalPort to 0. This allows the TCP/IP stack to choose a port at random. The value chosen is provided via the LocalPort property after the class is activated through the Active property.

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

Objects Property (SNMPTCPAgent Class)

The objects in the current request.

Syntax

• C++
• C

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

int AddUser(const char* lpszUser, int iAuthenticationProtocol, const char* lpszAuthenticationPassword, int iEncryptionAlgorithm, const char* lpszEncryptionPassword);

Unicode (Windows)
INT AddUser(LPCWSTR lpszUser, INT iAuthenticationProtocol, LPCWSTR lpszAuthenticationPassword, INT iEncryptionAlgorithm, LPCWSTR lpszEncryptionPassword);

int ipworkssnmp_snmptcpagent_adduser(void* lpObj, const char* lpszUser, int iAuthenticationProtocol, const char* lpszAuthenticationPassword, int iEncryptionAlgorithm, const char* lpszEncryptionPassword);

int AddUser(const QString& qsUser, int iAuthenticationProtocol, const QString& qsAuthenticationPassword, int iEncryptionAlgorithm, const QString& qsEncryptionPassword);

Remarks

The internal authentication cache can be used as an alternative to the GetUserPassword event, automatically checking the cache against the security parameters provided in the request signature.

The ShowCache method is used to show the contents of the internal authentication cache.

The ClearCache method can be used to completely clear the cache.

Valid Authentication Protocols are:

Valid Encryption Algorithms are:

NOTE: Specifying an authentication protocol of 0 is a special case where the class will attempt to verify users with all valid authentication protocols.

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.)

ClearCache Method (SNMPTCPAgent Class)

Clears the internal authentication database.

Config Method (SNMPTCPAgent 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_snmptcpagent_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.

int ipworkssnmp_snmptcpagent_sendresponse(void* lpObj, const char* lpszRemoteHost, int iRemotePort, int iRequestId, const char* lpszCommunity, int iErrorStatus, int iErrorIndex);

int SendResponse(const QString& qsRemoteHost, int iRemotePort, int iRequestId, const QString& qsCommunity, int iErrorStatus, int iErrorIndex);

Remarks

Use this method to send asynchronous response packets. A valid RequestId must be specified. SendResponse sends an unauthenticated response packet. Depending upon the value of the SNMPVersion property, the packet is constructed as an SNMPv1, SNMPv2c, or SNMPv3 (unauthenticated) response PDU. To send authenticated or encrypted SNMPv3 responses, use SendSecureResponse

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.

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.

Remarks

Similar to the SendResponse 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 GetRequest, GetNextRequest, SetRequest, or GetBulkRequest 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:

Valid Encryption Algorithms are:

Unicode (Windows)
INT SendTrap(LPCWSTR lpszRemoteHost, LPCWSTR lpszTrapOID);

int ipworkssnmp_snmptcpagent_sendtrap(void* lpObj, const char* lpszRemoteHost, const char* lpszTrapOID);

int SendTrap(const QString& qsRemoteHost, const QString& qsTrapOID);

Remarks

Depending upon the value of the SNMPVersion 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 SysUpTime property provides the trap timestamp.

SendTrap sends an unauthenticated trap. The SendSecureTrap 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 SysUpTime 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:

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.

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireDiscoveryRequest(SNMPTCPAgentDiscoveryRequestEventParams *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).

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 Oid, ObjectType, and 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:

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.

};

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

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireGetUserPassword(SNMPTCPAgentGetUserPasswordEventParams *e) {...}

Remarks

The GetUserPassword event is fired after initial inspection of SNMPv3 requests.

The type of password required is provided in the PasswordType parameter: 1 for authentication, and 2 for encryption (privacy).

The password corresponding to User (if any) must be provided in the Password parameter. If the password is valid, processing will continue to other events such as GetRequest, SetRequest, etc.

If the PasswordType parameter is 1 (authentication is used), the Algorithm parameter can be set. Possible values are:

If the password does not match the signature in the request, a BadPacket event will be fired, at which point you can decide whether to report the error to the client (see the description of the BadPacket 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 BadPacket event being fired, at which point you can decide whether to report the error to the client or not.

GetUserSecurityLevel Event (SNMPTCPAgent Class)

Sets the security level for an incoming packet.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireGetUserSecurityLevel(SNMPTCPAgentGetUserSecurityLevelEventParams *e);

typedef struct {
  const char *User;
  const char *EngineId;

};

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

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireGetUserSecurityLevel(SNMPTCPAgentGetUserSecurityLevelEventParams *e) {...}

Remarks

The GetUserSecurityLevel 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:

HashPassword Event (SNMPTCPAgent Class)

Fired before and after a password is hashed.

Syntax

• C++
• C
• Qt

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

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


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

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

#define EID_SNMPTCPAGENT_HASHPASSWORD 13

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

class SNMPTCPAgentHashPasswordEventParams {
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(SNMPTCPAgentHashPasswordEventParams *e);

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireHashPassword(SNMPTCPAgentHashPasswordEventParams *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

PacketTrace Event (SNMPTCPAgent Class)

Fired for every packet sent or received.

Syntax

  void SetEventRetVal(int iRetVal);
};

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

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FirePacketTrace(SNMPTCPAgentPacketTraceEventParams *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 (SNMPTCPAgent Class)

Fired when the class is ready to send data.

Syntax

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

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

Remarks

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

void Report(SNMPTCPAgentReportEventParams *e);

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireReport(SNMPTCPAgentReportEventParams *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 Oid, ObjectType, and 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.

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 Oid, ObjectType, and 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.

void SSLClientAuthentication(SNMPTCPAgentSSLClientAuthenticationEventParams *e);

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireSSLClientAuthentication(SNMPTCPAgentSSLClientAuthenticationEventParams *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 (SNMPTCPAgent Class)

Fires when connecting to the server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(SNMPTCPAgentSSLServerAuthenticationEventParams *e);

typedef struct {
  const char *RemoteAddress;
  int RemotePort;
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} SNMPTCPAgentSSLServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLServerAuthentication(SNMPTCPAgentSSLServerAuthenticationEventParams *e);

typedef struct {
  LPCWSTR RemoteAddress;
  INT RemotePort;
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;

} SNMPTCPAgentSSLServerAuthenticationEventParams;

#define EID_SNMPTCPAGENT_SSLSERVERAUTHENTICATION 19

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

class SNMPTCPAgentSSLServerAuthenticationEventParams {
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(SNMPTCPAgentSSLServerAuthenticationEventParams *e);

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireSSLServerAuthentication(SNMPTCPAgentSSLServerAuthenticationEventParams *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 (SNMPTCPAgent Class)

Shows the progress of the secure connection.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLStatus(SNMPTCPAgentSSLStatusEventParams *e);

typedef struct {
  const char *RemoteAddress;
  int RemotePort;
  const char *Message;
  int reserved;
} SNMPTCPAgentSSLStatusEventParams;


Unicode (Windows)
virtual INT FireSSLStatus(SNMPTCPAgentSSLStatusEventParams *e);

typedef struct {
  LPCWSTR RemoteAddress;
  INT RemotePort;
  LPCWSTR Message;
  INT reserved;
} SNMPTCPAgentSSLStatusEventParams;

#define EID_SNMPTCPAGENT_SSLSTATUS 20

virtual INT IPWORKSSNMP_CALL FireSSLStatus(LPSTR &lpszRemoteAddress, INT &iRemotePort, LPSTR &lpszMessage);

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

  int RemotePort();

  const QString &Message();

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

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

// Or, subclass SNMPTCPAgent and override this emitter function.
virtual int FireSSLStatus(SNMPTCPAgentSSLStatusEventParams *e) {...}

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.

Certificate Type

This is the digital certificate being used.

Syntax
