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

NAME
     talkd -- remote user communication	server

SYNOPSIS
     talkd

DESCRIPTION
     The talkd utility is the server that notifies a user that someone else
     wants to initiate a conversation.	It acts	as a repository	of invita-
     tions, 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.

SEE ALSO
     talk(1), write(1)

HISTORY
     The talkd utility appeared	in 4.3BSD.
