Biff is the name of a dog, when Unix first have a email alert program,
hackers want find a name for this program.
His dog biff always bite when he find the postman come, so the dog's
name biff become the program's name.
you need turn comsat server, comsat let the biff make sound.

I check the man page of comsat, but still cannot get any hint :(

what do you mean? the sentence do nothing or
because I have no letter? I try to email me with many emails :(
and it is strange in this board:
one possibility: few people comes here
the other possibility: people are not as man always mentioned:
people who love unix are lover to knowledge and always ready for
strange problem and helping others :)

/etc/services is only a table which let inetd to kow what process/protocal
and what port if the demo is running. It is staticly the same every where.
If you want start a tcp/udp demo in UNIX system, you need find where is
your inetd(or other) start from. Add comsat demo in it and restart inetd
(killall -HUP inetd)
Differet UNIX os using different demo system,I can't tell you more before
I know you OS.

This is true, UNIX is difficult for these M$ guys.
Cause some time we just don't know how to a

nothing to complain....
just to note another probability :
people came, and read your post, but just know no more than you do..
should be ready to read on your own..

I do not use biff now. You can use xbiff if you work on X.
If you always work on text based shell, your shell should tell you
when mail comes.

HP HPUN
SUN Solaris/SUN OS
IBM AIX
SGI IRIX
Compaq OSF
Compaq Trye 64
SCO UNIX Ware
Apple MAC OS X

Other may be BSD like, Linux Like, Minix Like, ....

Good,
put such line in your /etc/inetd.conf
comsat dgram udp nowait root /usr/sbin/tcpd in.comsat
And then
killall -HUP inetd
I haven't touch SUN for several years, maybe not right, just as reference.

我给你个一次性解决方案, 我写了一个 shell demo 来替代 comsat, 免得
去搞系统, 在说不同 shell, 也不同, 也许你的喇叭关了呢. 以后问问题
尽量描述清楚, 这样大家都很方便的.
把下面的程序 copy 到一个文件里, 后台运行. 有信件会 bell 三十声
注意, 也许要修改的部分是 ' { print $5 } ', 不过我测试过基本 run anywhere.
#!/bin/sh
mailcheck(){
COUNT=1
while [ $COUNT -lt 30 ]
do
echo -ne \\a
sleep 1
COUNT=`expr $COUNT + 1`
done
}
MAILST=`ls -l /var/spool/mail/$USER | gawk '{print $5 }'`
LOOP1=1
while [ $LOOP1 -lt 100 ]
do
MAILED=`ls -l /var/spool/mail/$USER | gawk '{print $5 }'`
if [ $MAILED -gt $MAIL
