NetBSD 6.1.5 - man page for talkd (netbsd section 8)

     ntalkd, talkd -- remote user communication server

     ntalkd [-dl]

     ntalkd is the server that notifies a user that someone else wants to initiate a conversa-
     tion.  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 request-
     ing 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.

     ntalkd supports the following options:

     -d     The -d option turns on debugging logging.

     -l     The -l option turns on accounting logging for ntalkd via the syslogd(8) service.


     talk(1), write(1), syslog(3), syslogd(8)

     The ntalkd command appeared in 4.3BSD.

     The original talkd program was coded improperly, in a machine and byte-order dependent fash-
     ion.  When this was corrected, it required a protocol change, which necessitated a different
     daemon to handle it, thus ntalkd or "new" talk daemon.  The old daemon has long since been
     removed, but the detritus remain.
