NAME

     talkd — remote user communication server

SYNOPSIS

     talkd [options]

DESCRIPTION

     talkd is the server that notifies a user that someone else wants to initiate 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 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.
