Thanks for answering. No actually I don't think someone is spoofing. There is a firewall (other machine, actually) blocking any kind of incoming&outgoing 127. adresses. So I don't think (at this time) that this is the problem.
What I ment with cron, is that there are daily reports the are being sent via sendmail. I've this sendmail option in rc.conf: sendmail_enable="NO". Sendmail is only listening on localhost. I assume that my freebsd host sends a auth command to 127.0.0.1 because a sendmail connection is being tried from 127.0.0.1. The samples of my 127.0.0.1 entries corresponds exactly at the time, that the daily reports arrives. Perhaps someone could confirm this? -----Original Message----- From: fbsd_user [mailto:[EMAIL PROTECTED] Sent: vendredi 23 janvier 2004 14:17 To: Didier WIROTH; [EMAIL PROTECTED] Subject: RE: log_in_vain="YES" If this is happening while your system is connected to the public internet then your system is under attack by somebody who is spoofing ip address 127.0.0.1. Port 113 is the ident protocol. There is no reason for the cron jobs to be doing that. You should power off you system when not in use at least until you install an firewall software solution. You really need an firewall, and should use IPFILTER as it's stateful keep-state rules function work correctly. FBSD's ipfw stateful rules are broken when used with ipfw's divert/natd function. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
