NAME
     talkd - invokes the remote user communication server

SYNOPSIS
     in.talkd

DESCRIPTION
     in.talkd is the server that notifies a user that somebody
     else wants to initiate a conversation.  It acts as a
     repository of invitations, responding to requests by clients
     wishing to hold a conversation.

     In normal operation, a client, the caller, initiates a
     session 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 invitation currently
     exists for the caller (to speak to the callee specified in
     the message).  If the lookup fails, the caller then sends an
     ANNOUNCE message causing the server to broadcast an
     announcement on the callee's login 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 connection through which the conversation takes
     place.
