having the same problem…...
FATAL ERROR: pf.conf => Table snort2c,src,kill don't exists in packet filter
looks like the file pf.conf should be in /etc/pf.conf but I can't seem to find it there on my pfsense box
http://www.freebsd.org/doc/handbook/firewalls-pf.html
http://www.openbsd.org/cgi-bin/man.cgi?query=pf.conf&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=htmlif the file isnt where its supposed to be no wonder snort cant find the table.....
-
the binaries didn't build last night. I heard that they are being built now. We just have to wait until they are built.
When it comes to snort, if you see a new version and don't understand pfsense and freebsd that well, wait till there is an announcement or experience users confirming that it works before re-installing.
other then barnyard, snort has been very stable for the last month.. Once in a while it has to be restarted on my box but only when I'm doing heavy heavy bit-torrent downloading..
-
I'm wondering if it's possible to make the package "publishing" via the GUI the last step? In other words, remove the installation option entirely until the binaries and code etc. have been pushed to the update server?
I check the packages regularly via the PF GUI, and if an update is there, tend to install it. The downside is that in cases like this, you can't go back and install the previous package. That said, I remain very impressed with PF in general since pulling the pin on the previous routers. Kudos to all in the chain.
Cino, can you describe (with a link or two if possible :-) ) the process you used to check github?
-
or add automatic checksum comparison to the package manager, this would prevent this problem and any man-in-middle attacks
-
Check out the github site for pfsense. There u can see the old changes and new ones.
-
Cino, is there a newby guide to checking github for snort? I had a look here but beyond that, no idea on what to do beyond that: https://github.com/pfsense/pfsense
-
there isn't and it would take me a while to make one..
the changes where done here https://github.com/pfsense/pfsense-packages/commit/e4c13a5752c5f7b4947edbc4227b005cd333566d You will have to manually edit the files.. Remove what is in green and add what is in red.. There is way to download the whole file it a few steps.
see if this helps everyone:

Thanks Cino, that did the trick !
I can now turn on Snort blocking :)
Here's the steps for the Newbies…
- SSH to the pfsense machine
- select 8) Shell
- cd /usr/local/pkg/snort/
- cp snort.inc snort.inc.bk
- fetch https://raw.github.com/pfsense/pfsense-packages/3b0730f14734da787f673bd81260f7c65f8c882e/config/snort/snort.inc
- cd /usr/local/www/snort/
- cp snort_interfaces_edit.php snort_interfaces_edit.php.bk
- fetch https://github.com/pfsense/pfsense-packages/raw/3b0730f14734da787f673bd81260f7c65f8c882e/config/snort/snort_interfaces_edit.php
Exit shell and try things out. If all works, then go back to shell and remove the two backup copies of the files (ie. rm the .bk files )
Curious if it works for others as well.

I have just changed the two files you mention and the problem seems the same. I am still getting the following error when I try to start Snort with "block offenders" on:
snort[12668]: FATAL ERROR: pf.conf => Table snort2c,, don't exists in packet filter
Any ideas?
-
binaries seem to be in but there are some issues..
@emarl The GUI doesn't have anything for the "Which ip to block" field under If Setting. Going to see if I can manually edit the conf file and see if I can get it to start when i have block offenders enabled.
log:
Jan 26 20:27:50 snort[52895]: FATAL ERROR: snort.conf => No option on which ip to block src/dst/both: Unknown error: 0 Jan 26 20:27:50 snort[52895]: FATAL ERROR: snort.conf => No option on which ip to block src/dst/both: Unknown error: 0
conf line is missing the new option:
output alert_pf: /usr/local/etc/snort/whitelist/MainWhiteList,snort2c,,
Still have to manually add the barnyard2 binary and add "portvar FILE_DATA_PORTS [$HTTP_PORTS,110,143]" under the advance
Edit: If i have Kill States enabled, snort to start..
output alert_pf: /usr/local/etc/snort/whitelist/MainWhiteList,snort2c,,kill
-
When you say that the binaries are there, does this mean that they will be used to install Snort in PFSENSE from the GUI? I have just reinstalled Snort and I still get the old error:
snort[48751]: FATAL ERROR: pf.conf => Table snort2c,,kill don't exists in packet filter
I still still version 2.02 when it should be version 2.1 I think?
-
there is new timestamp, you can check here http://files.pfsense.org/packages/8/All/. Because the way my box is setup, i have to manually add binaries after using the package gui.
-
The first time I "upgraded" to the new 2.1 version of SNORT I had three options under "Which IP to block"… SRC, DEST. and BOTH. They're not there now.

thanks catfish, i followed your instrustions and snort is working with the old gui!
one thing to note is i went to services in the gui and stopped the snort service before everything else, then ran your instructions, checked 'block offenders', and started snort without problems -
I completely uninstalled Snort and then reinstalled using the GUI. While I still see the wrong version (v 2.02), I can start it with host blocking on and it works so progress is being made :-)
I agree that there is a prblem with the select box "Which ip to block" as this is empty. I see no error generated by this as I think it defaults to SRC.
The previous version of Snort didnt remove the blocked hosts after one hour (as I had configured it to do). This is why I upgraded in the first place so I will wait for an hour and see if blocked hosts get removed! :-)

cino/catfish…thanks. The old gui with the two files copied in via your instructions works.
Cheers,
Dennis. -

if you go to the page where you select the time frame, when you save it; it should re-create the cron job.
should look kinda like this: */5 * * * * root /usr/bin/nice -n20 /usr/local/sbin/expiretable -t 3600 snort2c -
Cino, did you mean add code that is in green and remove the red?
You will have to manually edit the files.. Remove what is in green and add what is in red.. There is way to download the whole file it a few steps.

Hello
I have tried all the above steps, but now I'm getting a new error message:
snort[62529]: FATAL ERROR: Unable to open rules file "/usr/local/etc/snort/snort_47562_xl1//usr/local/etc/snort/snort_47562_xl1/reference.config": No such file or directory.
Any ideas?
Thanks.
