comsat — biff
Comsat is the server process which
receives reports of incoming mail and notifies users if they have requested
Comsat receives messages on a datagram
port associated with the “biff” service specification (see
services(5) and inetd(8)). The one line
messages are of the form:
user specified is
logged in to the system and the associated terminal has the owner execute
bit turned on (by a “
biff y”), the
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 terminal.
Lines which appear to be part of the message header other than the
“From” or “Subject” lines are not included in
- to find out who's logged on and on what terminals
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 email@example.com and include diffs/patches, compiler error logs or as complete a bug report as you are able.
