Name
       comsat - biff server

Syntax
       /etc/comsat

Description
       The command is the server process which receives reports of incoming mail and notifies users if they have requested this service.  The com-
       mand is invoked by when it detects an incoming packet on the datagram port associated with the ``biff'' service specification.  For further
       information, see The command reads the packet, which is a one line message 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 included
       in the displayed message.

Restrictions
       The message header filtering is prone to error.

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.
