Strange log in /var/log/messages about sendmail.

Post by ??? » Mon, 10 Jul 2000 04:00:00



I installed sendmail 8.10.x on a RedHat 6.2 box. I got a strange logs in
/var/log/messages.

Jul  9 19:36:54 coke sendmail[630]: NOQUEUE: ed.dk [194.192.187.81]
(may be forged) did not issue MAIL/EXPN/VRFY/ETRN
during connection to MTA

What does that log mean? And can I know who(IP) connected to my
mail server?

This means that somebody just  telneted  your smtp and didn't issue any
command.
his address ed.dk [194.192.187.81]

1. How large can /var/log/messages and /var/log/syslog get ?

My /var/log/messages is now over 3 meg, and my syslog is 200+ k. I'm
very curious how far is this going to go ?
Is there a way to restrict their sizes ?

cheers,
Hong Siang.

The sticker on the box said, "Windows 95, Windows NT 4.0, or better."
So I installed Linux.
