4. Suricata not working!

Suricata not working!

  • W

    I did the update today. Wish i didn't. :(  Snort doesn't work anymore ( i can't even download the rules) and i have all my network exposed to external attacks. Can't go back to the old working version.

    Also, the new interface is…  geez, crap. The ergonomy is a lot minimized. Anyone can help me go back to the old version? Before doing the update i made a full back-up from the update interface, but now i can't find any back-up. :((  I have a lot of critical servers, includind VoIP and GPS servers behind the firewall and i'm totally exposed now.

    Bellow is some errors from suricata logs.

    P.S. Yeah, i know i should't have done this update without a strong back-up in production enviroment, but i've trusted to much the pfSense development team. :(  Learnt my lesson.

    I don't know if this still works in 2.3, but I have found that reinstalling packages from the console often fixes them.
    https://forum.pfsense.org/index.php?topic=92577.msg513026#msg513026

    I had to use the same technique today with snort after reinstalling 2.2.6 and restoring my backup.

    I have already tried that. I can download the rules now, but the snort still doesn't work. Because i'm in a f*****g production enviroment i must find another solution quicik. Most probably i will go back to the old version of pfsense,

    Your post says "Snort not working" yet you posted logs of Suricata starting up.  Which are you actually trying to utilize?

    Try going to the UPDATES tab and clicking FORCE to force an update.  Let it sit there for several minutes!  Do not navigate away from the page (not even after the little modal dialog disappears).  Just let it sit there for maybe 3 or 4 minutes.  Then click the button to view the log file.  Post any errors you see there back here.  I'm betting that if you let it sit long enough on the UPDATES tab, you will get the rules.

    The rules are downloading at a point as i said, but the suricata doesn't work. No detection, no blocking, no alerts.  Deleted the package, reinstallled, without success. Unfortunately, as i did mention above i'm in a production enviroment. I wish i had time to investigate this issue, but i'm working hard to go back on 2.2.6 and restore a full back-up. I'm feeling (and i am) like a complete idiot for deploying this new version of pfsense in a productions enviroment without waiting a couple of months.

    As for the logs, that's all what i had in suricata.log after the update.

    Bellow is a more recent suricata.log Anyway, most of the errors doesn't relate with the malfunction of the Suricata.

  • All of those "SC_ERR_INVALID_SIGNATURE" errors are just Suricata complaining about keywords and rule options in Snort VRT rules that Suricata cannot interpret.  This is expected when using the Snort VRT rules package with Suricata.  Those errors are harmless in that they do not prevent Suricata from starting up; however, they do mean those particular rules are not getting loaded and thus are never being used to inspect traffic.  So from that point of view the network security is reduced.

    I'm still confused by the title of your thread.  It says "SNORT" but your logs are all Suricata.  Which package are you really running?  I assume Suricata ???  If so, then post the end of the Suricata log (you can skip all the rule parsing errors and just post the stuff after that).

    Sorry, it was a rough day. I've modified the tittle of my post. I realized now what i have written there.  I know those errors are not related to my problem, but i thought someone could find something usefull there.  I'm now on 2.2.6 again and i've abandoned all the hope on 2.3. For the moment. I must setup a test rig to check the potential of 2.3. Thank you for your reply.

    Hey we all have rough days, but just remember that Bill maintains the Snort and Suricata packages on his own time, and everyone here benefits from it…  It would be really great if more people participated in the testing/development phase, instead of waiting on a final polished version. Also keep in mind that you will see new Snort/Suricata package features in pfSense 2.3 that might never get ported back to 2.2. Some food for thought...

  • There are a handful of known issues in the current Suricata GUI package for pfSense 2.3.  I have all of those but one fixed in the code version I'm working on.  That last remaining issue to make the rules update download process a little more user-friendly by providing some visual feedback of progress.  I've said this in other posts, but internal changes in pfSense as a result of the Bootstrap migration made some of the system API calls I was using to show rules download progress no longer function the same.  I'm trying to come up with a viable workaround.

    I would be interested in learning more about your specific problem if you can take the time to try 2.3 again in the near future.

    This is my first post.  8)  I just installed a fresh installation of pfSsense 2.3 as a VM on ESXi 6.  All services run except Suricata. I turn on Suricata and in 30sec it switches back off automatically.  I've reinstalled it several times, and I didn't have this issue with any previous version.

    You will need to post some log data.  Post the suricata.log file from the interface where Suricata runs (it will be in /var/log/suricata/xxx (where xxx is the interface combined with a GUID).  Also post any relevant messages, if any, from the pfSense system log from around the time of the crash.

    There wasn't anything Suricata related in the system log that was odd. I will note I have OpenVPN setup for PIA VPN, not sure if that could cause issue.

    Thank you!!! That worked!  8)

    It's hard to tell how much I need, but i just increased it from 64MB to 128MB.

    For those looking to find the setting in version 2.3 its, Services > Suricata > Interfaces > Pencil Edit Icon under Actions > LAN Flow/Stream > Stream Memory Cap

  • Darn it!  I thought I had the Stream Memory Cap default set large enough, but apparently not true in all situations.
