  talkd, ntalkd	- The remote communications server for the talk	command





  The talkd server notifies a user or callee when a client or caller wants to
  initiate a conversation. The talkd daemon sets up the	conversation if	the
  callee accepts the invitation.  The caller initiates a conversation by exe-
  cuting the talk command and specifying the callee.  The callee accepts the
  invitation by	executing the talk command specifying the caller.

  The talkd daemon listens at a	socket for a LOOK_UP request from a local or
  remote talk client.  On receiving a LOOK_UP request, talkd scans its inter-
  nal invitation table for an entry that pairs the client (the local or
  remote talk process) with a caller.

  If an	entry exists in	the talkd daemon's international invitation table,
  the talkd daemon assumes that	the client process is the callee. The talkd
  daemon returns the appropriate rendezvous address to the talk	process	for
  the callee.  The callee process then establishes a stream connection with
  the caller process.

  If an	entry does not exist in	the invitation table, the talkd	daemon
  assumes that the client process is the caller. The talkd daemon then
  receives the client process's	ANNOUNCE request. When talkd receives the
  ANNOUNCE request, talkd broadcasts an	invitation on the console of the
  remote host where the	callee is logged in, unless the	caller specifies a
  particular tty.  At approximately 1-minute intervals,	talkd rebroadcasts
  the invitation until either the invitation is	answered by the	callee or the
  call is canceled by the caller.

  Debugging messages are sent to syslogd(8). For further information on	the
  files	used by	this daemon, see the syslogd command.


  The Tru64 UNIX version of talkd uses the talk	4.3BSD protocol. This command
  is sometimes referred	to as ntalkd. It is not	compatible with	4.2BSD ver-
  sions	of talk.
