     talkd - remote user communication server




     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.


     talk(1), write(1)


     The talkd command appeared in 4.3BSD.
