 NAME    [Toc]    [Back]
      talkd - remote user communication server

 SYNOPSIS    [Toc]    [Back]

 DESCRIPTION    [Toc]    [Back]
      Talkd is the server that notifies a user that someone wants to
      initiate a conversation.  It acts as a repository of invitations,
      responding to requests by clients wishing to initiate a conversation.
      To initiate a conversation, the client (the talk command) sends a
      message of type LOOK_UP to the server (see
      /usr/include/protocols/talkd.h).  This causes the server to search its
      invitation table to check if an invitation currently exists for the
      caller to talk to the callee specified in the message.  If the lookup
      fails, the caller then sends a message of type ANNOUNCE, which causes
      the server to display an announcement on the callee's terminal
      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.

      To activate the talk service, the following entry must be added to the
      /etc/inetd.conf file:

           ntalk  dgram  udp  wait  root  /usr/lbin/ntalkd ntalkd
