-
this is fixed in the package now

What is fixed?
i do not see any package update?
can you please be more specific what is fixed? and how? did you add the preprocessor "dcerpc2" and the preprocessor "dcerpc2_server" ?
or just modify the snort.inc to disable the use of them? -
@cmb:

OK, Confirm that it is now working after i uninstall and reinstall from the package. Thanks guys you guys are highly appreciated.

Well it is not really fixed…. netbios rules still get snort to fail.

Use the netbios.rules from the so_rules folder.

I've tried all of the suggestions contained within this thread and it's still not functioning properly. My PfSense box has been up and running for over 30 hours and not a single Snort alert in all that time. I just don't understand what the problem is. Can anyone advise?
Thanks…

Do you have any snort rules in the Categories section of snort? If you are using pfsense 1.2.2 version i believe that it's haveing problem updating the rules so you might have to manually download the latest rules from snort.org and do a SSH and also manually install the rules. If you have the latest rules already install than you might have to start the service.

Ironically, Snort worked perfectly on 1.2.2. The problems started as soon as I "upgraded" to 1.2.3 RC-1. After monkeying with it for far too long, I finally "downgraded" back to 1.2.2–a version known to work on my machine. Unfortunately, Snort doesn't run on 1.2.2 now either. But I appreciate the suggestion. I'll try it again.

I would tell you to try reinstalling snort; there was a problem recently and doing a reinstall corrected my brief issues, so do that first. Then try re-doing your pfSense box. I can't say how many times I've redone mine over problems I didn't understand. Which has got me in hot water with the Mrs. I have changed my setup at least 10 times. I now have two pfSense boxes running snort - the netbios rules + using ac-bnfa and have squid running on the second box behind the first WAN connected pfSense box. If at first you don't succeed, try again.

Hi.
Sorry I have been gone. I just started a new job and have been really busy.
Snort 2.8.4.1 right now does not work because the mysql client port is out of date.
Mysql client needs to be at mysql 5.1, dependencies libdnet-1.11_3.tbz and pcre.7.9 must be installed.
Moreover, It seems that the snort port and the mysql client port were built on different machines.
Sourcefire is using the new RPC2 netbios rules so snort needs to be at snort 2.8.4.1.My snort.inc is good so theres no need to comment out the RPC2 options.
I emailed the core team on how to fix the package hopefully this will be resolved today.
I'll be hear all day so, please ask and I will respond to any messages.thanx

Did you update the rules at all after installation? If not update..should start.

Seems to be working great on pfs 1.2.3 w/dual wan & CP, thanks for the update.

If any of you are still having problems. Please fallow these steps.
1. Reinstall snort. (So that the new code gets updated.)
2. Deinstall snort. (New code deinstalls all the old snort packages.)
3. Install the snort package.
4. Update the rules.
Finished, snort should work now.

i've just modified /usr/local/etc/rc.d/snort.sh and changed:
snort -c /usr/local/etc/snort/snort.conf -l /var/log/snort -D -i em1 -A fast -q
to:
snort -c /usr/local/etc/snort/snort.conf -l /var/log/snort -i em1 -A fast -q &
then the snort work properlyis there any way to trace the problem?
thanks.
