NAME

       talkd — remote user communication server

SYNOPSIS

       /usr/sbin/in.talkd [-dpq]

DESCRIPTION

       Talkd  is  the server that notifies a user that someone else wants to initiate a conversation.  It acts 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 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.
