Correction: in the meanwhile it jumped to 47890 KB, I don't know why. Logrotation?.

Hi,
...for the records...:
Since I switched "Loglevel" to OFF, memory usage stays at "14333 KB" and didn't change/rise since then.

Hi,
Sounds interesting.
So I thought I take a little test...
Initial RAM-Usage: 14334 KB
First I just switched logging, did nothing else:
syslog => file => 22726 KB file => syslog => 31117 KB syslog => file => 39507/47898 KB (RAM suddenly altered. Why? No idea.) file => syslog => 56289 KB
Restarted through console:
root@ipfire: /var/log/guardian # guardianctrl restart Stopping Guardian... Starting Guardian... Unable to continue: /usr/sbin/guardian is running [ WARN ]
Hm?
Stopped through console, no output, 'guardian' not found anymore, neither in GUI nor through console:
root@ipfire: /var/log/guardian # ps ax | grep guardian 6962 pts/1 S+ 0:00 grep guardian
Started through console and we're exactly where we started (14334 KB).
The same happens if I switch the 'Priority-level' or the 'Firewall-Action'.
Initial: 2 2 => 3 => 22723 KB 3 => 2 => 31112 KB
Firewall-Action: Reject => Drop => 39501 KB
Stop => Start => 14334 KB
Interestingly, during MY (log-)switching, 'guardian' never stopped.

I am now noticing that when I switch from Log facility “file” to “syslog”, Guardian Daemon stops and doesn’t restart. Switching from syslog to file didn’t stop the service, only switching back to syslog from file. I can manually start the service and be back to normal. Not a big deal, but if someone made the switch and didn’t think to manually start the service, it could be left without running Guardian.

Hi,
I mentioned this earlier, but it seems that 'guardian' has some kind of memory leak?
It started about two days ago with ~14 MB RAM. Then it jumped to ~34 MB, then to ~48 MB - today it suddenly uses 71 MB.
And if I start it on my testmachine (offline!) it uses ~90 MB.
Can someone confirm?
Besides this, its working without seen problems.
Best, Matthias

Hello testers,
I've uploaded a new test version (003).
Update or fresh install works like described in the announcement mail.
The Changelog can be found here:
http://people.ipfire.org/~stevee/guardian-2.0/Changelog.txt
At the moment I'm missing feedback for the following functions:
- Manually blocking / unblocking addresses.
- Dealing with the ignore list.
- Owncloud message parser.
- Logrotate, there should be an corresponding log entry in the guardian
logfile after rotation of the logfiles have been done.
- Reload of the ignore list after "Red" has been reconnected. There
also a corresponding log entry should be logged to the logfile and the new "Red-address" should also be logged as part of the ignore list (If you own an dynamic assigned one).
As always please report your bugs or experience with the new version to this list.
Best regards,
-Stefan
Hello mailing list followers,
this is the official release announcement for the first beta release of the new Guardian 2.0 approach.
- What are the differences to the current version of guardian
(legacy) and the first approach of guardian 2.0?
The most important difference is, that the new version of Guardian 2.0 completely has been re-written from scratch and released under the terms of the GPLv3. The legacy version of guardian is not maintained anymore by it's developer and the software has been released without any license details at all.
Guardian 2.0 has a very modular code base and has been designed as a multi-threaded application. This allows a parallel parsing of all monitored logfiles and faster actions, if one of the used modules detects an attack.
A very important difference to the legacy version is the support of configuring and managing the entire service through the IPFire webinterface. The entire configuration, managing of current blocked hosts, unblocking them or editing the ignored hosts list now can be done in a graphical way.
The legacy version of guardian only supported parsing snort alerts. HTTPD and SSH support has been patched by the IPFire development team some time ago. Guardian 2.0 supports all of them out of the box and includes a filter to detect owncloud login brute-force attempts. As a benefit of the new modular design, additional filters easily can be added.
Guardian 2.0 is able to reload it's configuration, reloading the ignore list during runtime and handle, if the logfiles will get rotated by logrotate. This actions can be called by using the webinterface or from the command line interface by using "guardianctrl".
These are just a handful of the changes and benefits which comes with Guardian 2.0, a complete list would be to long for this mailing list.
- How to join testing?
To get part of the testing team, simple navigate to http://people.ipf ir e.org/~stevee/guardian-2.0/ and download the latest tarball (currently 002). Please take care to download the correct one, based on your used architecture. The i585 packages are for 32Bit installations of IPFire, the x86_64 packages only can be used on 64Bit installations.
Put the downloaded file on your IPFire test system and extract the package by using "tar -xvf guardian-2.0-002.<arch>.tar.gz -C /".
The final installation step would be to regenerate the language cache by executing "update-lang-cache" on the console.
From now you can find a new menu item called "Guardian" in your "Service" menu after you have logged-in into your IPFire's webinterface.
Documentation can be found on the IPFire wiki: http://wiki.ipfire.org /e n/addons/guardian/start#the_guardian_20_addon
- Where to post bugs reports or provide feedback?
If you find any bugs, please report them as usual on the IPFire bugtracker, which can be found at https://bugzilla.ipfire.org.
To provide feedback or to join a discussion, please send your mails to "development@lists.ipfire.org" (Please register first at http://lists .i pfire.org if not yet done).

Happy testing,
