ntalkd, talkd —
| ntalkd | [ -dl] | 
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 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.
ntalkd supports the following options:
-d-d option turns on debugging logging.-l-l option turns on accounting logging for
      ntalkd via the
      syslogd(8) service.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
    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.
