IN.COMSAT(1M) Maintenance Commands IN.COMSAT(1M)


NAME


in.comsat, comsat - biff server

SYNOPSIS


/usr/sbin/in.comsat


DESCRIPTION


comsat is the server process which listens for reports of incoming mail
and notifies users who have requested to be told when mail arrives. It is
invoked as needed by inetd(1M), and times out if inactive for a few
minutes.


comsat listens on a datagram port associated with the biff service
specification (see services(4)) for one line messages 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 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, To, Date, or Subject lines are not printed when displaying the
message.
