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

SYNOPSIS
       talkd

       ntalkd

DESCRIPTION
       The  talkd  server  notifies  a	user or callee when a client or caller
       wants to initiate a conversation. The talkd daemon sets up the  conver‐
       sation  if  the	callee accepts the invitation.	The caller initiates a
       conversation by executing the talk command and specifying  the  callee.
       The  callee accepts the invitation by executing the talk command speci‐
       fying 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
       internal 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 ta‐
       ble, 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  rebroad‐
       casts  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.

NOTES
       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 versions of talk.

FILES
