NAME    [Toc]    [Back]

     talkd - remote user communication server

SYNOPSIS    [Toc]    [Back]

     /usr/etc/talkd

DESCRIPTION    [Toc]    [Back]

     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 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 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.
