Snort 2.9.2.3 pkg v. 2.5.0 Issues

mdima

@mdima:

Hi,
anyone for the local IPs blocked when "block: both" is selected? Am I the only one having this issue?

Thanks,
Michele

I'm having the same issue with src being selected. Its blocking my WAN IP. No matter which way its enter in HOME_NET and/or Whitelist.. It getting blocked. I believe ermal is looking into the issue

Ok, thanks. The important is that this issue is known and shared, because if I am the only one I have to ask myself what I am doing wrong…

Thanks,
Michele

@ermal:

I pushed a fix to the sensitive data rules.
Please test it after 30 minutes.

@ermail: is it possible to add the snort build number/date somewhere in the GUI? This way everybody nows exactly where they are.

I would prefer not since its not needed and you are just reporting bugs here.

Ermal this is still not fixed.

If snort is running and downloads a new rule update then tries to apply it, the same will occur. I have the latest version update. Of course if I uninstall snort and reinstall it will start again and run fine but it is still not fixed as the next rule update will cause the same error.

A reinstall and snort will still not start with a different error:bad-traffic.so <- This rule is not even enabled.

I am getting the same error. If I let it auto update this happens without fail. If I have the package removed and installed fresh, and manually update the rules I do not get this error. I do not have the sensitive data option enabled in the preprocessor section. (havent enabled it since it was an option on that tab) I generally do not change my rules/categories or options. They have been the same as they have been for a year or so now.
I am on the latest pfsense build that I can grab (official) and the latest snort version that has been pushed. FOr now I have disabled the auto update since its more important for me to have snort running at the moment rather than erroring out and not running due to this.

_igor_

same here. I disabled the auto update too.

aaronritter

same problem here:

i fixed it by doing this:

added the line: config classification: sdf,Sensitive Data was Transmitted Across the Network,2
at the end of: /usr/local/etc/snort/classification.config

and disabled auto update for now

dwood

I have two installations working fine, (2.0.1) and autoupdates set for every six hours for testing. So far so good..however the error may return when the rules are actually updated. I suspect that there are no new rules yet which would have triggered an actual update.

EDIT: Yep, an update (emerging threats) triggered same error. Removed, erased snort bits, reinstalled and started fine. Turned off updates for now. The good news is that snort is behaving and blocking just fine otherwise :-) Thanks Ermal.

Btw, the WAN blocking issue has not re-occurred on two AMD64, 2.0.1 installations. Important to note that snort should be uninstalled, then run "find /* | grep -i snort | xargs rm -rv" , then reinstall. This ensures you get a new SNORT binary..at least for now, reinstalling won't replace the SNORT binary file.

Cheers,
Dennis.

Should behave better if you just reinstall.
No new binary needed.

After reinstall I got

FATAL ERROR: /usr/local/etc/snort/snort_4672_em1/preproc_rules/preprocessor.rules(202) Unknown ClassType: sdf

After complete reinstallation snort rules download failes. Not even the md5 file gets downloaded.

php: /snort/snort_download_rules.php: Snort rules file downloaded failed…

Maybe snort server is down...but I get message that there is a new set available.

EDIT: 7 hours later and after another reinstallation snorts starts up without error and snort.org rules were downloaded. Everything seems to work so far...

aaronritter

Can anyone tell why this is missing after auto rule update:

added the line: config classification: sdf,Sensitive Data was Transmitted Across the Network,2
At the end of: /usr/local/etc/snort/classification.config

Ermal this is still not working. I reinstalled the latest. downloaded the rules clicked start same error as before.

bad-traffic.so is not selected in snort rules.

tester_02

It's so close now… I'm still on 2.9.1 and waiting for the list of issues to die down and I can see it's almost there.
Just wanted to thank all Ermal AND all the users doing the testing. Everyone's help is appreciated by the rest of us.

Cino

^^^ he was the smart one ::)

all my testing is on my home box, so i dont care if it breaks here and there… now the wife on the other hand is a different story... But she is best user tester... I know within seconds if the internet is down... In this case, snort blocking facebook or pinterest because it didn't like the http packets that were sent over..

I couldn't wait for my box to auto update but wanted to test your changes before i leave for my annual military training. So I ran the the cron job from shell and seems to work.. It downloaded a new set of rules and started snort… I love the fact now we dont have to download a new ruleset went we do a reinstall.. Thank you again!!!

Are you sure when you ran the rule update there was indeed an update downloaded?

dwood

Ermal, reinstalled (AMD64, 2.0.1) and got this:

Jul 18 22:04:22 snort[23595]: FATAL ERROR: Failed to load /usr/local/lib/snort/dynamicrules/bad-traffic.so: /usr/local/lib/snort/dynamicrules/bad-traffic.so: Undefined symbol "freeRuleData"
Jul 18 22:04:22 snort[23595]: Loading dynamic detection library /usr/local/lib/snort/dynamicrules/bad-traffic.so…

However, an uninstall, manual delete, and reinstall worked. Will set to autoupdate and see what happens.

digdug3

Had the same issues with auto-update. I didn't reinstall, but just updated manually and the manually restarted the Snort interface(s).
This worked for me this time. Will disable auto-update in the meanwhile.

Looks like I spoke too soon, check again this morning. And it failed

judex

At the moment snort ist working ok.

Autoupdates fail but snort keeps on snorting on my system.

Manual update works, if I delete snortrules MD5 file before.

WAN blocking does not occur any more.

Hi, I was updating this morning, few hours ago, and my WAN IPs were still get blocked (block: Both), even if they are on the whitelist (both choosing a whitelist then leaving "default" as whitelist)…

Thanks,
