I'm a newbe to logcheck and need some help writing a rule.

Here's the output I'm trying to  block:

Nov  1 09:11:52 m0n0wall ipmon[79]: 09:11:52.330133 xl0 <at> 100:3 p 192.168.2.201 ,1900 -> 239.255.255.250,1900 PR udp len 20 291 K-S IN

And here's my rule in /etc/logcheck/violations.ignore.d/local-m0n0

^\w{3} [ :0-9]{11} m0n0wall ipmon\[[0-9]+\]: [0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{6} xl0 <at> 100:3 p 0-9]\.[0-9]\.[0-9]\.[0-9],1900 -> [0-9]\.[0-9]\.[0-9]\.[0-9],1900 PR udp le9n 20 291 K-S IN$

The rule is on one line in the single file (it's the only rule in the file)

I've tested it using:

sed -e 's/[[:space:]]*$//' /var/log/syslog | egrep '^\w{3} [ :0-9]{11} m0n0wall ipmon\[[0-9]+\]: [0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{6} xl0 <at> 100:3 p 0-9]\.[0-9]\.[0-9]\.[0-9],1900 -> [0-9]\.[0-9]\.[0-9]\.[0-9],1900 PR udp le9n 20 291 K-S IN$'

and it prints out the data I wish to block.

Anyone have any ideas?

Thanks,

It turned out the the rule was fine, however for some reason the file wants to see a CR/LF at the end of the rule, even if it's the only rule.

Thanks,

I'm trying now two write a rule that will filter out all outgoing port 80 requests from users.

How do I make a list of the variables I'd like to search for?

XXX.XXX.XXX.XXX,80 PR tcp len 20 52 -AF IN
XXX.XXX.XXX.XXX,80 PR tcp len 20 52 -AR IN
XXX.XXX.XXX.XXX,80 PR tcp len 20 52 -S K-S IN

the AR, AF and S-K are the three I'd like to search for.

Here's a bit of code I've got running for the K-S.

[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3},80 PR tcp len [0-9]{2} [0-9]{2} -S K-S IN$


Thanks,

Denis
