NAME
     comsat -- biff server

SYNOPSIS
     comsat

DESCRIPTION
     Comsat is the server process which receives reports of incoming mail and notifies users if
     they have requested this service.	Comsat receives messages on a datagram port associated
     with the ``biff'' service specification (see services(5) and inetd(8)).  The one line mes-
     sages are of the form:

	   user@mailbox-offset

     If the user specified is logged in to the system and the associated terminal has the owner
     execute bit turned on (by a ``biff y''), the offset is used as a seek offset into the appro-
     priate mailbox file and the first 7 lines or 560 characters of the message are printed on
     the user's terminal.  Lines which appear to be part of the message header other than the
     ``From'' or ``Subject'' lines are not included in the output.

FILES
     /var/run/utmp  to find out who's logged on and on what terminals

SEE ALSO
     biff(1), inetd(8)

BUGS
     The message header filtering is prone to error.  The density of the information presented is
     near the theoretical minimum.

     Users should be notified of mail which arrives on other machines than the one to which they
     are currently logged in.

     The notification should appear in a separate window so it does not mess up the screen.

     Please report bugs to netbug@ftp.uk.linux.org and include diffs/patches, compiler error logs
     or as complete a bug report as you are able.

HISTORY
     The comsat daemon appeared in 4.2BSD.
