new problem.. After updating snort, all the menu items for other packages are missing. I did a full firmware update so it would re-download all the packages.. Same thing, all package menu items are removed but Services-Snort is there..

countryblock, LCDproc, cron, shellcmd, vnstat2, ntop, notes are all missing from the menu

EDIT: I removed the code that was added to pkg-utils.inc, https://github.com/bsdperimeter/pfsense/commit/27018d3cc4f12c995efadf5dc5ba90eb7c1aa641 Rebooted the box and did a package re-install.. Now my package menu items are there

white list doesn't work.. I put the IPs into my home net list and snort also blocked them.

i checked my conf file and var HOME_NET contains none of the IPs i added. Not sure how the white list works since it broke a long time ago. The file "MainWhiteList 10285" doesn't contain any of the IPs i put in that list either.. Also, there is a space in the file name..

Well the whitelist option in snort:interfaces:edit works only if Block offenders is on!

I had Block offenders on and it was blocking whitelist IPs. I noticed you made some more changes… I'll update and retest

EDIT: new issue, snort wont start. See below:

also change https://github.com/bsdperimeter/pfsense/commit/27018d3cc4f12c995efadf5dc5ba90eb7c1aa641 is still removing package menu items. I see that you put a piece back in https://github.com/bsdperimeter/pfsense/commit/05ca39d93d972908e61da6f1b0b9132dd39b017b but that didn't fix it

as i re-install a package, its removing the last installed package from the menu

Edit: I' opened a ticket on this as this has nothing to do with Snort but with 2.1 Development code, ticket 1743

I can confirm same issue as above on the latest update. I do not have a problem with the package removal though

eri-- · Aug 3, 2011, 7:56 PM

Hmm just remove and reinstall the binaries again not just the snort files.
Those are files that come wiht the package difficult to loose those without something wrong :)

EDIT:

I put another fix to prevent the errors you are seeing.

All my re-installs have been 'Reinstall this Package'

btw, thank you very much for the quick responses on fixing the snort package as i'v been finding issues… I've been kind hoping other users would be reporting on issues other then myself since there was an outcry for snort a week ago...

I've already done two reinstalls of PfSense 2RC3 in the last week due to things going awry during a snapshot update (which may or may not have been related to having snort or snort-dev installed), and my first attempt to install the new snort didn't go too well (Snort was missing from the menu and services list after installation but someone else reported this before I could, with more insight as to the circumstances under which it occurred than I had).

So I'm afraid, I'm sitting on the fence at the moment, waiting for an all-clear!

Just did a reinstall same error:
Aug 3 15:06:12 snort[18906]: FATAL ERROR: parser.c(5165) Could not stat dynamic module path "/usr/local/lib/snort/dynamicpreprocessor": No such file or directory.

Snort was this morning this only started occurring after the reinstall.

@emarl Im able to start snort again :-) had some issues starting it but i forgot that in my main home net list, i have to uncheck 'Add WAN DNS servers to the list.' since I have a IPv6 in my WAN DNS entries. Snort doesn't like IPv6 yet.

looking at the conf file, my net list is there.. Going to test the IDS then enable blocking and see if whitelist works again.

EDIT: Issue with the suppress file again. The file looks good

the file:


# This file is auto generated by the snort package. Please do not edit this file by hand.

suppress gen_id 119, sig_id 2, track by_src, ip 68.x.x.x

system log


Aug 3 16:28:32 	SnortStartup[57067]: Interface Rule START for 0_39737_em3...
Aug 3 16:28:32 	snort[56934]: FATAL ERROR: /usr/local/etc/snort/suppress/(1) Invalid configuration line: Ú^Y^O
Aug 3 16:28:32 	snort[56934]: FATAL ERROR: /usr/local/etc/snort/suppress/(1) Invalid configuration line: Ú^Y^O

Whitelist isn't working. It is creating the file but there is a space in the name "MainWhiteList 10285" Also when I check 'Block offenders' and Select 'MainWhiteList' from the drop down; it goes back to 'default' when i click on 'Save'

mschiek01: Remove the package and install it again.
Do not use the reinstall features but really delete and install the pacakge.

That will fix your issue and it should not happen again after that.

eri-- · Aug 3, 2011, 9:04 PM

@cion

should be fixed the issues with whitelist selection and suppress.

Cino · Aug 3, 2011, 9:14 PM

thanks again Ermal!! I can't test right now but later tonight I will remove everything snort relate, do a firmware update(maybe a fresh install) and after my packages update i'll install snort.

not sure how this happen but I started up some bit-torrent downloads and it killed snort i think but it could just be my box..

Aug 3 17:01:11 	snort[26553]: FATAL ERROR: s2c_pf_block() => ioctl() DIOCRADDADDRS

when i started it back i got this:

Aug 3 17:03:41 	snort[58868]: FATAL ERROR: pf.conf => Table snort2c don't exists in packet filter

but i'm having issues with countryblock now so i need to do a reset before I can test again

That is IDS integration which might need some people to help out in funding to make properly usable.

I am having the same issue now of not seeing Snort menu entry under Services, even after successful install. I have uninstalled and installed the Snort package a couple times already as per the earlier suggestion.

I see the following error messages on system log which I thought were relevant:

Aug 3 17:28:50 SnortStartup[36465]: Snort HARD Reload For 21540_em0_vlan10…
Aug 3 17:28:50 snort[36189]: FATAL ERROR: Unable to open rules file "/usr/local/etc/snort/snort_21540_em0_vlan10//usr/local/etc/snort/snort_21540_em0_vlan10/rules/emerging-botcc.rules": No such file or directory.

Now even if there were some issues with the category 'emerging-botcc.rules', I cannot uncheck those now since I cannot bring up Snort setting to uncheck those.

That fixed the issue.

Thanks again for addressing this quickly.

Ok, Snort is running now. I had to export the config xml and edit out the rule categories which were generating exceptions on system log as stated before. Once I restored it, Snort is now running although I still feel that Snort should not die if choosing what it considers as a invalid category.

Anyway, now I have a different issue which I am not sure if it is Snort install related since I also updated to the latest snapshot. Now, I can install Squid or Squidguard or Cron individually, but if I install more than one, the other gets bumped off of the services list. Even the menu entry for the previous package is lost. In other words, only one service can be active at a time from among installable packages. This is just a rough observation since I haven't tried all different combinations of packages.

What IDS integration are you talking about?

So far so good! Whitelist looks to be working. I notice the format of the file has change. Suppress file seems to load without errors, have not tested yet. thank you again!
