Well, clearly something wrong somewhere.

Hello Wayne,
once more thanks for your testing and providing such detailed feedback.
Restored backup from core127 with guardian against a fresh suricata iso install. Found: IPS service was running with no rules downloaded. Box's checked were enabled, monitor, red and blue. It did import the oinkcode but no rules sets downloaded automatically.
Thats correct, there was no code, which called the downloader in such a case. I've added it now to the "convert-snort" script, so in future if a snort config has got imported and no ruleset is present it automatically will be downloaded.
Since I had two rule sources in guardian I wondered how that would be handled here were one set is all that's possible. Picked a set and downloaded them, had to manually pick the rules. Not a big deal to setup. Made an attempt at importing the suricata tarball into current release core127 with guardian installed but no luck. Tar command exits with "This does not look like a tar archive". Had used "tar -xvf" to extract... Could be doing something wrong here?
Mhm, I've checked the archives they work here, may an incomplete download?
The md5 checksums should be:
c5a6830336fdb75cc1c59e735a0fa655 ipfire-2.x-suricata-rc3_i586.tar.gz 300943d7e6fa667b7c33843124182b4f ipfire-2.x-suricata-rc3_x86_64.tar.gz
Please only extract the "outer" tarball and call the "install.sh" script.
Thanks in advance,
-Stefan
Regards Wayne

Hello again and thanks for the feedback.
Exposed my test setup directly to my cable modem and noticed a couple of things.
-The Firewall log seems to only list items that match my firewall rules. Gone was the typical several a minute "drop_input" entry noise, there was zero drop_input's in 15min or so. Possible logging issue?
The IDS/IPS events are not logged to the firewall log. They only can be accessed in the "Logs"->"IPS Logs" section.
-Suricata placed entries into IPS log, but what is done with them? Don't see a block list like Guardian generated.
Thats exactly how suricata works and the main benefit why we choose to switch to suricata.
The old snort/guardian solution worked like this:
Snort detected (based on it's ruleset) an event and logged it to it's logfile. Guardian read this event from the file, parsed it again and if the configured block count for the matching IP-address was reached, the host was blocked by an iptables rule (block list).
The new suricata-based solution works like this:
Suricata detects (also based on the ruleset) an event and directly drops the bad package. There is no additional software involved anymore .
So one of the benefits of the new approach is to reduce the amount of time an attack has been recognized until it's blocked immediately.
-Are there any incompatibility issues with using the backup function to restore to this version? I had made a backup from my core 127 system with the old intrusion detection/guardian not active just in case.
There is a converter-script available, which will move the old snort/guardian and rules settings to be used by suricata. This script automatically will be called if a backup gets restored, which contains such settings files.
Therefore I would ask you to test this feature by restoring such a backup on a fresh installed nightly machine and if possible to install the "update tarball" on a regular machine with configured snort and/or guardian.
In both ways, all your taken settings should be the same for suricata as before for snort.
A big thanks in advance and best regards,
-Stefan
Regards Wayne

Yep I had downloaded the nightly and suspected is was not current, and so posted the build number.
With the 5d7d8749 loaded I have not seen any of the previous issues nor any others thus far.

Hello Wayne,
it seems you accidentally downloaded and tested the wrong image.
The latest one is 5d7d8749 were you downloaded one is an older release.
Sadly the nightly build service and therefore the images are one day later than the upgrade tarballs....
You simply can update to this release by using the RC3 tarball or download the available "5d7d8749" ISO.
Best regards,
-Stefan
Loaded the new iso, reports build 77c07352. Still having connection issues with suricata as soon as its activated where existing connections would continue to work, no new connections were possible. Reboot results in no connection timeouts. Disable suricata, reboot, connections work.
Any graphical data trend under Status tab reports errors and remains blank. Typically on new installs the trends at least show the chart even though data had not been collected.
Configured options: Geoip Proxy on green and blue URL filter suricata on red/blue Running a number of emerging threats rule sets.
Regards Wayne

Hello list,
I've uploaded the third release candidate, which hopefully would be the last one.
It fixes the issue that no traffic could be passed through the firewall when suricata was running on some machines and no graphs could be displayed anymore. Thanks to Wayne for reporting and Michael Tremer for testing and fixing.
The new tarball (i586 for 32bit-systems, and x86_64) can be found here:
https://people.ipfire.org/~stevee/suricata/
To start testing download the tarball and place it on your IPFire system. Extract the tarball and launch the install (install.sh) script.
If you already have installed a previous test version or image, with the same steps as noted above you can update the the new version.
As always, if you prefer a fresh installation, the latest image can be grabbed from here:
https://nightly.ipfire.org/next-suricata/latest/x86_64/
Direct link for downloading the ISO image:
https://nightly.ipfire.org/next-suricata/latest/x86_64/ipfire-2.21 .x 86 _64-full-core128.iso
Thanks for downloading and testing. There are no known bugs so far, as usual please file any bugs to our bugtracker ( https://bugzilla.ipfire.org) and share your feedback on the list.
Best regards,
-Stefan
