TALKD(8)		  BSD System Manager's Manual		      TALKD(8)

NAME
     talkd -- remote user communication	server

SYNOPSIS
     talkd

DESCRIPTION
     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 message causing
     the server	to broadcast an	announcement on	the callee's login ports re-
     questing 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.

     The talkd command appeared	in 4.3BSD.
