Snort Won't Start After Upgrade

Cino

We need to be able to dedicate more of our core developer resources to clean this up and keep it working, as is it's largely just Rob's volunteer efforts, where the base system is largely done by people on our payroll (who, no offense to Rob, are far more experienced developers). What gets done by our core developers is largely what people are willing to pay for, and it's been years since we've had anyone interested in paying for Snort work. I've dedicated 10 hours of Ermal's time (with no funding, as a favor to a partner) to cleaning up bugs and bad code in the Snort package this week, which has lead to this massive clean up today, with more work to be done on it tomorrow.
https://github.com/bsdperimeter/pfsense-packages/commit/c8b7c369d1b391fc687e4ad09ee156dbec37043a

That's not going to leave things in perfect shape (there are other improvements I'd like to see), but it will at least be much better. That's limited to the main snort package, not snort-dev, which Rob can continue to do whatever he wants with, but nothing will be merged back into the main snort package from now on without review and merge approval to keep things sane.

If anyone can dedicate some money to furthering our efforts here, please contact me (cmb at pfsense dot org). I'd love to get more of our resources on it, but we also have to make payroll so we're limited in what we can do because we want to do it.

funny I just checked github to see what updates are out there and Ermal has been busy!! I see the old snort package is enable… Who is going to be the brave soul and try it? Well i gave it shot and it installed on my system but it couldn't download the rules from snort.org

Warning: curl_exec(): Could not call the CURLOPT_WRITEFUNCTION in /usr/local/www/snort/snort_download_rules.php on line 859

I guess i should wait until the devs say its good to go.

going to see if i can manually download them

@cmb is right snort should be maintained by the core paid developers. My work on snort package will stop immediately and will move my code to a package called Orion.
I have really enjoyed giving my free time and code to the pfSense snort community. I hope people continue to enjoy my GUI I have built and code I have donated.
Those of you that expect the Old snort gui to return dont worry, 90% of my snort 1.2.3 code will not change for 2.0.

My snort 2.0 package I was working on will become Orion IDS package and will likely become private for paid supporters. This will help me give my full attention to this package.
I think I have a base now that can support me to work on this package on a limited part time.

Moreover, this should give me the freedom to add features as fast as possible.

I just made some other changes that should make it behave better in regards to rule downloading.

I couldn't test with snort.org since it was slow and did not have an account to test with.

Cino

This makes sense if i'm reading this last couple of post correctly. Snort being maintained my the core dev team.. If users want more then a basic Snort package… They have the option to pay for the Orion IDS.

@Ermal I'll give it a shot but you are right! Snort.org is really slow today... My manual updating from the cmd failed due to timeouts

Cino

Snorts site is timing out so i can't test. emergingnet rules downloaded with no problems.

When I tried to start snort on my WAN interface, this is the error i received:

Warning: Invalid argument supplied for foreach() in /usr/local/pkg/snort/snort.inc on line 92 Warning: fopen(/usr/local/etc/snort/suppress/): failed to open stream: Is a directory in /usr/local/pkg/snort/snort.inc on line 1184 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/snort/snort.inc:92) in /usr/local/www/snort/snort_interfaces.php on line 192 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/snort/snort.inc:92) in /usr/local/www/snort/snort_interfaces.php on line 193 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/snort/snort.inc:92) in /usr/local/www/snort/snort_interfaces.php on line 194 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/snort/snort.inc:92) in /usr/local/www/snort/snort_interfaces.php on line 195 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/snort/snort.inc:92) in /usr/local/www/snort/snort_interfaces.php on line 196 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/snort/snort.inc:92) in /usr/local/www/snort/snort_interfaces.php on line 197

This is in my system log:

I don't know if this is relate to adding snort or my mornings gitsync but when i look at my system log i get the below errors. I'm able to see the system log tho but this is at the header of the page. Also, none of the other tabs are showing this error(firewall,dhcp,openvpn)

Now i'm asking for too much, could it be possible to add a index.php in the root of the snort www directory with the below code? So when i click on the pfSense image in the upper left corner, it brings back to the main dashboard page instead of page no found.

EDIT: The permissions are wrong on the /usr/local/etc/rc.d/snort.sh file I believe. Its currently 644, should 755. i tried to manually start snort using the snort.sh but i think there is an syntax error with the interface

Hello,

i am running the latest pfsense 2.0 rc3 from today and have installed the snort 2.0 package as a virtual machine on kvm. If i want to edit the network interface in the snort settings, i get an "error: no uuid". How can i fix this problem?

Regards, valle

eri--

@Cino,

should be fixed, just reinstall.

@valshare,

please give me the right error message since that does not mean anything!

NightHawk007

The thing on this forum that just does not sense .People do not read the forum snort has been broken for a long time now .there was a couple of posts on the forum saying it will be awhile before it gets fixed .
Will someone tell us how far it has come and is the beta out yet for us to test out .
I am using my standbye UTM software with snort in there operating system and it works perfect .

@ermal:

@Cino,

Almost there… it seems to forget the interface.. I noticed that you made some changes to how it puts the interface, wondering if something is missing there.

I deleted all my snort configs... Added a interface... told me i had no rules... updated the rules again.... checked some rules.... tried to start it, didn't start. Went back to the categorizes and was told i dont have rules... its picking the wrong directory or something.

Try the new update i just made.

That is the startup script and not the config. But for now all should be fixed.

sorry about that… Just tried the new updates and seeing a different error... snort engine is trying to start tho. When i'm in 'Snort: Interface Edit:' the server, preprocessors, barnyard2 tab show the interface as '0em3' instead of '39737 em3' but the other tabs are showing the interface correctly.

EDIT: I found the issue in the conf file under var HOME_NET 01.1/32,/,192.168.5.1/24

was able to manually start snort after editing the conf file :-)

It doesnt create the folder/file for the suppress list

I have a couple of issues:

1. When updating rules, when it tries to download the snort.org rules, the following error is shown at the bottom of the page and the rules are not processed:

Warning: curl_exec(): Could not call the CURLOPT_WRITEFUNCTION in /usr/local/www/snort/snort_download_rules.php on line 820

2. If I have the option enabled to "Keep snort settings after deinstall" and then reinstall the package, the menu link for Snort does not appear and Snort is not listed in the "Status: Services" page. I have to backup the config, remove the "snortglobal" section, upload the new config and reinstall Snort to fix it.

Thanks!

Thank you all for great work - snort kicks back online on my router - I really felt naked during last few weeks.
BTW. If I understand it correctly classic snort package maintenance was shifted from JamesDean, I really admire his work, I can only hope that you will get on well.

I think that no 1 is fixed with the latest update (package version did not change).
I encountered the same issue as in no 2, although I didn't try fiddling with config yet.
What I did was simply use direct link to snort webconfiguration:
http://192.168.1.1/snort/snort_interfaces.php
to update rules and start snort and it seems to be working correctly.
During the snort "holiday" break I messed up with the snort-dev package - maybe something left over from it.

First let me say thanks for getting this package back now I can go back to testing ;D

The only problem I've found is that if you tick the Block Offenders under the if settings tab then snort refuses to restart. The following error is logged.

snort[9497]: FATAL ERROR: /usr/local/etc/snort/snort_50697_bce0/snort.conf(351) Unknown output plugin: "alert_pf"

Untick the box and it fires up fine but obviously no hosts get added to the block list.

Just got the e-mail that this was fixed. Awesome! Thank you!

@Ermal great work! I found small bug with the Suppress List. The interface doesn't seem to be saving the file needed for the interface to come up. Is the path wrong?

I'm going to do more testing with white list and home net list today and report back… I know white list wasn't working in the old package but the work around was to use the home net instead if you needed to white list an IP.

All the issues should be solved now.
Please reinstall and test.

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
