 Name

    talkd - remote user communication server

 Syntax

    /etc/talkd [-d]

 Description

    talkd is the server that notifies a user that somebody else wants to ini-
    tiate 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 talk client initiates a rendezvous by sending a
    CTLMSG to the server of type LOOKUP (see <protocols/talkd.h>).  This
    causes the server to search its invitation tables to check if an invita-
    tion currently exists for the client.  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.

 Options
