talkd - remote user communication server
talkd
Talkd is the server that notifies a user that someone else wants to ini- tiate a conversation. It acts as a repository of invitations, responding to requests by clients wishing to rendezvous to hold a conversation. In normal operation, a client, the caller, initiates a rendezvous by sending a CTL_MSG to the server of type LOOK_UP (see <protocols/talkd.h>). This causes the server to search its invitation tables to check if an invita- tion currently exists for the caller (to speak to the callee specified in the message). If the lookup fails, the caller then sends an ANNOUNCE mes- sage causing the server to broadcast an announcement on the callee's lo- gin ports requesting contact. When the callee responds, the local server uses the recorded invitation to respond with the appropriate rendezvous address and the caller and callee client programs establish a stream con- nection through which the conversation takes place.
