(View In Hierarchy)
The Identification Protocol (a.k.a., "ident", a.k.a., "the Ident Protocol") provides a means to determine the identity of a user of a particular TCP connection. Given a TCP port number pair, it returns a character string which identifies the owner of that connection on the server's system.
Server authors should subclass this class and override the lookup method. The default implementation returns an UNKNOWN-ERROR response for every query.
Method | lineReceived | Override this for when each line is received. |
Method | invalidQuery | Undocumented |
Method | validQuery | Called when a valid query is received to look up and deliver the response. |
Method | lookup | Lookup user information about the specified address pair. |
Method | _cbLookup | Undocumented |
Method | _ebLookup | Undocumented |
Inherited from BaseProtocol (via LineOnlyReceiver, Protocol):
Method | makeConnection | Make a connection to a transport and a server. |
Method | connectionMade | Called when a connection is made. |
Inherited from BaseProtocol (via LineOnlyReceiver, Protocol):
Method | makeConnection | Make a connection to a transport and a server. |
Method | connectionMade | Called when a connection is made. |
Inherited from BaseProtocol (via LineOnlyReceiver, Protocol):
Method | makeConnection | Make a connection to a transport and a server. |
Method | connectionMade | Called when a connection is made. |
Override this for when each line is received.
Parameters | line | The line which was received with the delimiter removed. (type: bytes ) |
Called when a valid query is received to look up and deliver the response.
Parameters | portOnServer | The server port from the query. |
portOnClient | The client port from the query. |
Lookup user information about the specified address pair.
Return value should be a two-tuple of system name and username. Acceptable values for the system name may be found online at:

This method may also raise any IdentError subclass (or IdentError itself) to indicate user information will not be provided for the given query.
A Deferred may also be returned.
Parameters | serverAddress | A two-tuple representing the server endpoint of the address being queried. The first element is a string holding a dotted-quad IP address. The second element is an integer representing the port. |
clientAddress | Like serverAddress , but represents the client endpoint of the
address being queried. |
