Part of twisted.protocols.ident View Source 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||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.|
Inherited from LineOnlyReceiver:
|Method||dataReceived||Translates bytes into lines, and calls lineReceived.|
|Method||sendLine||Sends a line to the other end of the connection.|
|Method||lineLengthExceeded||Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.|
|Method||connectionLost||Called when the connection is shut down.|
|Method||makeConnection||Make a connection to a transport and a server.|
|Method||connectionMade||Called when a connection is made.|
|Parameters||line||The line which was received with the delimiter removed.
|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.|
