Hi Jeremy,

Is there a manual for using pulled-pork? I can't find the manual for it in
http://www.snort.org/docs

Thank you very much.

1/2 - Look at pulled-pork to handle the rule management tasks; including
enabling all the rules if that's what you want

3 -  www.testmyids.com for a quick test, there may or may not be rules
written for the vulnerability checks.

check your snort.conf for proper variable usage

learn what the rules do and why you expect them to fire.

Dear list,

I downloaded this set of rules file http://www.snort.org/downloads/2874 (
snortrules-snapshot-2960.tar.gz <http://www.snort.org/downloads/2874>).

Why are most of the Snort rules commented out? It's like 80% of all the
Snort rules are commented out/disabled.

Question 1: Shall I un-comment the disabled rules???

Also, why are many of the rules files empty?

Question 2: Why are many of the rules files empty?

I installed Nessus 5.2.6 on my Windows 8.1 machine. I ran Nessus
vulnerability scanner against my public IP and no alerts showed up on my
Snort IDS at all!

Question 3: The Nessus vulnerability scanner reported numerous
vulnerabilities. Why are there no alerts in my Snort IDS box at all?

I need a favor from you guys. To uncomment all the DISABLED Snort rules,
which is probably thousands and thousands of lines, is a colossal task. I
think I need to write a sed 's/original text/replacement text/g' linux
shell script to uncomment all the disabled Snort rules. But the problem is
that my Linux shell scripting knowledge is a bit rusty and I would need to
revise it. Hence I am wondering if any of you guys can write a bash script
with sed and for loops to uncomment the disabled Snort rules??? Thanks in
advance!!! Don't worry, I will vet through the submitted shell scripts.

I am looking forward to your replies.

Thank you very much.

Yours sincerely,

Teo En Ming
