I saw the same thing at varnish report. Every time you apply settings, it will be included. Make report simple and it will never return.

Hi, I'm also new to snort… I'm just wondering if there is any easier way to search for a rule. I have a lot of them and when I want to review one upon an alert, I have to do find the matching one by hand.. The same with suppression....

CPU usage on my Atom D525 X64 with Snort enabled is really low, like 1%

This is not an issue anymore.  After upgrading to pfSense 2.0, I can set up my configuration so I don't need to run Snort on the LAN interface.  Thanks

Hello I have had exactly the same issue while updaing to one of post RC3 snapshots. Whole upgrade proces take about 6 hours to complete and looping screens was quite annoing, but when it finished system working stable till now. Now, when we have the final release, I will install fresh system and will restore from backup file Regards

You can use all: I've set this scenario some times and it worked very well. Https -> haproxy –--                             |---> apache + modsecurity -->  webserver Http -> varnish ------ You can Also set this: Apache+modsecurity ---> varnish --->  web servers(/test)                                            |-----> Web servers (/test2) In this case, apache handles ssl. Notes: Apache can do what you want but today the package Does not include this option. May be in a close future I may include this feature to gui. Varnish is faster then apache as a reverse proxy, do a test if you have time.

@jimp: Not sure what might be happening on your system, but on mine it keeps the settings when I uninstall it, reinstall it, or upgrade. Same here…. All fine.

@stvboyle: I seem to be having the same problem.  I'm running: 2.0-RC3  (amd64)  built on Tue Sep 6 17:46:35 EDT 2011 Installed snort, configured updates, enabled a WAN interface, enabled all preprocessors, enabled some rules, started it on the interface.  Its been running for about 12 hours now and no alerts.  Not sure how to troubleshoot the issue.  Any suggestions are appreciated. Have a look at http://forum.pfsense.org/index.php/topic,37557.285/topicseen.html for the cause and the solution of this issue.

@photonman: @serialdie: you can use ntop. Ntop is pretty cool…I think that will work out for me. thanks for the suggestion Been using it for a few years and is an awesome monitoring tool. Good Luck!

Perfect! It works! Hope to see soon an updated version of the cool package. Thanks again Romain

If you are using auth and msn client can't use your authentication method, you will ser this error. Check in log if urls that has a tcp_miss has also a username. You may need To create An acl by client address and map msn urls.

any update on this package? is this dead already?

You got a l7 filter to make this.

the widget has not work for some time now… at least 8+ months on the 2.0 branch... clearing alerts was reported a while ago and there is a ticket on it already http://redmine.pfsense.org/issues/1765

You can also try memory cache, its faster then Disk. With a lot of sites setting sessions, squid is not so efficient To handle this.

I'm all set, now… When I made it back to my test network earlier today there were system log entries on the pfSense box showing the ethernet interfaces had been restarted. The reason they restarted on their own while I was doing other things is a mystery to me, but they did restart. Shortly after that, Snort kicked off successfully for both interfaces I set it up on and was running just fine. Again, not sure why it decided to start right up on its own, but I had asked it to start repeatedly before working on other things, so maybe it just did what I told it to as soon as it could.  ??? I notice it clearly states on the Snort service web-interface that the interfaces will need to be restarted to pick up changes. Changes like just installing it to configuring it to run for the first time, say? Nice  ;D Once I had a running Snort install and the correct arguments for 'ps', it was easy to answer my own questions.

one possible cause for this that i have found: I was testing the cron command that updates the rules by running it manually.  The first time i got a few duplicate SID warnings.  I went and disabled a few rules and re-enabled them and ran it again and got a bit different output. Line 15 is: enablesid Line 19 is: disablesid I then went and disabled/reenabled a few more rules, and when i ran the update command i got more of the WARNING: line xx in your oinkmaster_blah.conf is invalid.  All of the warning lines were either "enablesid" or "disablesid" with nothing more. Each time i disabled a rule and ran the update, it would add one more "disablesid" to the /usr/local/etc/snort/snort_<interface_id>/oinkmaster_<interface_id>.conf file and each time i enabled a rule and ran the update it would add one more "enablesid" to the same file. I'm not sure how this relates to the problem, but it seems like snort is not able to keep track of which rules are enabled/disabled properly and when it merges the updates with the current rules it formats them in a way that the web interface cannot handle.
