Re: Pass Rule not working?

Don't think so. I have my daemon set up to run -o.

Been running the command /usr/local/bin/snort -u Snorter -o -U -d -D -c /etc/snort/snort.conf -i eth1 -l /var/log/snort in /etc/rc.d/init.d/

I thought that was the problem too, but it doesn't solve anything for me.

And since it came in while I was typing this one:

In response to Shane: I know that *.*.*.* isn't a valid IP, I just didn't see any particular reason to hand out the IP addresses of my servers. The stars are supposed to represent an actual IP address, not a wildcard, since the snort wildcard is indeed any. Thanks, though.

Q: Why does the program generate alerts on packets that have pass rules? A: The default order that the rules are applied in is alerts first, then pass rules, then log rules. This ordering ensures that you don't write 50 great alert rules and then disable them all accidently with an errant pass rule. If you really want to change this order so that the pass rules are applied first, use the "-o" command line switch.

I've been getting alerts in ACID because of ICMP packets. The message is ICMP Destination Unreachable (Communication Administratively Prohibited) I know this particular issue has been addressed previously and I think I understand why it's happening. The servers on my Home Net are trying to ping to places that they aren't allowed to ping and the packets are being returned by an intermediary device. Trying to be clever, I wrote a pass rule in my local.rules file:

pass icmp any any -> *.*.*.* any (itype: 3; icode: 13)

I'm still getting errors.

What'd I do wrong?
