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. cURS5n[U5S:waUR5 g[[U5up4[ Us=::a [ ::a-O O*[ Us=::a [ ::aO OURX45 gUR[R"[55X45 g![a UR5 gf=f)N,) splitlen invalidQuerymapint _MIN_PORT _MAX_PORT validQuery _ebLookuprFailurer" ValueError)rlineparts portOnServer portOnClients r lineReceivedIdentServer.lineReceivedHs 3 u:?     -0e_* ::!\>Y>OOL?NN 6  $!!# $sB66CCc8URR5 gr ) transportloseConnectionrs rr/IdentServer.invalidQuery\s %%'rcFURR5RU4nURR5RU4n[R "UR X45RURX5RURX5 g)z Called when a valid query is received to look up and deliver the response. @param portOnServer: The server port from the query. @param portOnClient: The client port from the query.
