NAME

4     talkd — remote user communication server

SYNOPSIS

7     talkd [-dp]
8

DESCRIPTION

10     Talkd is the server that notifies a user that someone else wants to ini‐
11     tiate a conversation.  It acts a repository of invitations, responding to
12     requests by clients wishing to rendezvous to hold a conversation.  In
13     normal operation, a client, the caller, initiates a rendezvous by sending
14     a CTL_MSG to the server of type LOOK_UP (see ⟨protocols/talkd.h⟩).  This
15     causes the server to search its invitation tables to check if an invita‐
16     tion currently exists for the caller (to speak to the callee specified in
17     the message).  If the lookup fails, the caller then sends an ANNOUNCE
18     message causing the server to broadcast an announcement on the callee's
19     login ports requesting contact.  When the callee responds, the local
20     server uses the recorded invitation to respond with the appropriate ren‐
21     dezvous address and the caller and callee client programs establish a
22     stream connection through which the conversation takes place.
