Snort Won't Start After Upgrade

[eri--]

The amd64 support is there but look at redmine.pfsense.org under snort category of issues on pfSense-packages project.
I am trying to put there all known issues though solving those is not only based on my or pfSense good will :), some help is needed as well.

Ermal,

I know folks here have reported that the blocked hosts being cleared after the set time is working now, but I have not had success with that working yet. I have attached my screen shot of Cron entries on my system and don't think the job to remove the blocked hosts exists for Snort. I uninstalled and installed Snort just a few minutes back, so I am positive that I am running the latest iteration of your changes.

Thanks,
Hiranmoy

Never mind…..My mistake. Turns out I did not hit 'Save' after having installed the latest Snort package. The Cron entries appeared after that.

Thanks!

@ermal and others

Today I updated my AMD64 PFSense system (Intel Atom CPU D510 @ 1.66GHz) to the latest available snapshot (2.0-RC3 (amd64) built on Tue Aug 2 22:54:59 EDT 2011).

Snort completely deinstalled before updating to latest snapshot. Reinstalled Snort, but Snort cannot be found in any menu whatsoever. Furthermore, Snort service is not available either. Tried again: completely deinstalled Snort, restarted PFSense and reinstalled Snort again with no results.

Any suggestions on how to solve the menu and service issues?

You need to do a gitsync or wait for a new snapshot to come out.

Thanks ermal! It worked out by following the guide @ http://doc.pfsense.org/index.php/Updating_pfSense_code_between_snapshots. Menu and service are back again.

However (don't shoot the messenger), Snort service still won't start … as before. Just like:

@asterix:

Latest amd64 snapshot. Clean install.

Snort not starting.

That says the service is started.
Any other logs to claim that snort is not starting Ibor?

@ermal  startup is quiet… thanks again!

Thank you for helping in testing Cino.

need users to test it and report back with detailed errors… this will help the dev fix issues

Thank you for helping in testing Cino.

Anytime! I may just re-install my system this weekend or next week and try amd64

Mainly based on the following (see attached images):

• (dashboard widget system information) memory usage before and after are the same

• (dashboard widget services status) service status still indicates "stopped"

• (main snort menu) icon remains as "green play icon", not turned to "red cross button"

BTW if you require additional log file(s), feel free to ask. Please note: I'm not that familiar what log file(s) Snort use(s) exactly within PFSense. Guidance is then appreciated. If wanted I'm available for testing/debugging.

You just did but saying the binary is missing.

[seattle-it]

You just did but saying the binary is missing.

You make zero sense .. anyways, back to reality:

I've been able to get Snort + Barnyard to a working state with the current Snort package. For others that may be running into similar issues, the quick fixes i had to apply were:

1. pkg_add -r barnyard2
2. ln -s /usr/local/etc/snort/snort_<digits>interface  /usr/local/etc/snort/snort_ <interface>I've had other front-end issues with my config not being saved properly. Something triggers it to blank out interface and other snort settings, which is a pita. Things seem to work from the UI now, but I'm sticking with using the terminal to control things (and will probably roll out my own 2.9.0.X binary eventually).</interface></digits>

@Ermal  I'm testing the amd64 platform. Snort starts and seems to be work but when I check Block Offenders, I get this error

Aug 5 23:49:30 	SnortStartup[62468]: Interface Rule START for 0_39737_em3...
Aug 5 23:49:30 	snort[62343]: FATAL ERROR: /usr/local/etc/snort/snort_39737_em3/snort.conf(351) Unknown output plugin: "alert_pf"
Aug 5 23:49:30 	snort[62343]: FATAL ERROR: /usr/local/etc/snort/snort_39737_em3/snort.conf(351) Unknown output plugin: "alert_pf"

line 351 from my conf

output alert_pf: /usr/local/etc/snort/whitelist/defaultwlist,snort2c

snort2c table is defined under tables, whitelist files look to be the same format as i386

I retested i386 and it doesn't have this problem, its able to block offenders… would this happen to do with the amd64 snort binaries?

also noticed if i try to clear the alerts, it goes to a blank page without clearing the alerts (Does this on i386 and amd64)

I can confirm Snort and suppress working again with RC3-build 05-08 i386.
Barnyard is NOT working because it is not installed during the update process, that's why barnyard.conf does not exist.
Reinstalling the package will not bring Barnyard alive also. I think this is the reason for the GUI to break as well.

Second problem i have is this when I enable the snort_netbios.rules:

snort[26631]: FATAL ERROR: /usr/local/etc/snort/snort_61390_em1/rules/snort_netbios.rules(152) GID 1 SID 3239 in rule duplicates previous rule, with different protocol.

I noticed that too when I install the amd64 ver, that barnyard wasn't installing. it did try to change some of the files but came back with files not found.

uncheck netbios and it should start… you may get some more errors that are rules related... uncheck the rules until snort starts. These kind of errors I believe are not because of the snort package but because of the rules themselves. Sometimes its a duplication because of the .so rules and/or when you are using 2 different rulesets(emerging and snort together).

emerging threats seems to be okay after deleting and installing again .  I have not been able to clear the alerts log after hitting clear then ok just endup on blank page.

note: now seems to quit adding to log
