NAME
       talkd - remote user communication server

SYNOPSIS
       /usr/libexec/ntalkd

DESCRIPTION
       Talkd  is  the  server  that  notifies  a  user	that somebody else wants to initiate a conversation.  It acts 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 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.
