NAME

     ntalkd, talkd -- remote user communication server

SYNOPSIS

     ntalkd [-dl]

DESCRIPTION

     ntalkd 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 broad-
     cast 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.

OPTIONS

     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.

HISTORY

     The ntalkd command appeared in 4.3BSD.

     The original talkd program was coded improperly, in a machine and byte-order dependent fashion.  When this was corrected, it required a pro-
     tocol 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.
