3 | .SH NAME | |
4 | comsat \- biff server | |
5 | .SH SYNOPSIS | |
6 | .B /etc/comsat | |
7 | .SH DESCRIPTION | |
8 | .I Comsat | |
9 | is the server process which listens for reports of incoming mail | |
10 | and notifies users if they have requested this service. | |
11 | .I Comsat | |
12 | listens on a datagram port associated with the ``biff'' service | |
13 | specification (see | |
14 | .IR services (5)) | |
15 | for one line messages of the form | |
16 | .PP | |
17 | .ti +0.5i | |
18 | user@mailbox-offset | |
19 | .PP | |
20 | If the | |
21 | .I user | |
22 | specified is logged in to the system and the associated terminal has | |
23 | the owner execute bit turned on (by a ``biff y''), the | |
24 | .I offset | |
25 | is used as a seek offset into the appropriate mailbox file and | |
26 | the first 7 lines or 560 characters of the message are printed | |
27 | on the user's terminal. Lines which appear to be part of | |
28 | the message header other than the ``From'', ``To'', ``Date'', | |
29 | or ``Subject'' lines are not included in the displayed message. | |
30 | .SH FILES | |
31 | .DT | |
32 | /etc/utmp to find out who's logged on and on what terminals | |
33 | .SH "SEE ALSO" | |
34 | biff(1) | |
35 | .SH BUGS | |
36 | The message header filtering is prone to error. | |
37 | .PP | |
38 | Users should be notified of mail which arrives on other | |
39 | machines than the one they are currently logged in to. | |
40 | .PP | |
41 | The notification should appear in a separate window so it | |
42 | does not mess up the screen. |
