Re: Snort package should work now…Post problems here.

1.2.3-RC2, Snort 2.8.4.1 pkg v. 1.2

Snort do not update correctly. From the GUI, it appears to download the rules but never creates the ../rules folder (and I only see the Snort tar.gz.md5 file in the snort folder).

I'm having to manually download the rules manually, and place them in /usr/local/etc/snort/rules everytime I want to update.

My falt I was updating code yesturday and broke snort for a little while when I was updating code and I forgot to update the version number.

Just reinstall snort package and the probem will go away.

I just did a test and its working for me with the latest code.

Snort 2.8.4.1 pkg v. 1.3
PFSense version 1.2.1 built on Thu Dec 25 14:48:40 EST 2008
Hardware: VIA ITX, VIA C3 Samuel 2 800 Mhz

Rules updates are not working correctly. The script downloads the latest rules, but watching the drive activity light on the machine, it stops during the 'extracting the rules' stage.

I have rebooted, no change.
I have reinstalled the package, tried removing and reinstalling the package, no change.

I am fairly sure it is not a space or memory issue as the drive the PFSense install is on is largely unused and the system has a gig of physical memory.

Example stats from top:
Mem: 48M Active, 39M Inact, 129M Wired, 1212K Cache, 109M Buf, 759M Free

Using firefox, the throbber stops and top doesn't show tar running. Using IE (shudder), it seems to get further but exhibits the same end result. This makes me think that it's timing out, but it's never been a problem previously.

Using the script as a guide, I manually installed the rules but now have the error of "FATAL ERROR: Unable to open rules file: ../rules/local.rules or /usr/local/etc/snort/../rules/local.rules" appearing in the logs. snort2c does end up running in the end.

I cant figure out why your system is not seeing /usr/local/etc/snort/rules/local.rules. Even when the file exists.
I cant reproduce this type of error.

Do me a fav in the terminal type.

ee /usr/local/etc/snort/rules/local.rules

add a # i the file.

and then restart snort through the terminal

snort -c /usr/local/etc/snort/snort.conf -l /var/log/snort -v -i ng0

Where would I put the addition? Beginning or end?

EDIT: I tried restarting snort via the GUI again and this time it worked without any errors. Go figure.

And as for the automagic update failing, am I correct in my idea that it's just timing out? I could rerun the extract commands and time it (something I should have done, sorry).

jamesdean

I'm glad snort package is working for you.

Timing out ? Make shure you wait 15 min befor trying to update.

That's the download stage that needs to wait 15 minutes I believe.

The download phase works fine, it's during the extraction that the apparent timeout happens.

I'm using a ALIX 2d3 board that's 500 mhz and 256 ram and it takes around 5 minus to extract.

Give it some more time….

I gave it several hours during one attempt and it never progressed beyond the extracting rules phase.
