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.
