comsat
DESCRIPTION
Comsat is the server process which receives reports of incoming mail and
notifies users if they have requested this service. Comsat receives mes
sages on a datagram port associated with the ``biff'' service specifica
tion (see services(5) and inetd(8)). The one line messages are of the
form:
user@mailbox-offset
If the user specified is logged in to the system and the associated ter
minal has the owner execute bit turned on (by a ``biff y''), the offset
is used as a seek offset into the appropriate mailbox file and the first
7 lines or 560 characters of the message are printed on the user's termi
nal. 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

biff(1), inetd(8)
BUGS
The message header filtering is prone to error. The density of the in
formation 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.
