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:
|Class Variable||delimiter||The line-ending delimiter to use. By default this is
|Class Variable||MAX_LENGTH||The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.|
|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||logPrefix||Return a prefix matching the class name, to identify log messages related to this protocol instance.|
|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. (type: |
|Parameters||portOnServer||The server port from the query.|
|portOnClient||The client port from the query.|
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.|
