There should be sync messages written to the system logs (especially on the destination machine). I probably forgot to add a "sync trigger" to the new OpenAppID code. I will check that so that when it is enabled/disabled, a sync is forced. Bill

@simby: Bill can you please share your list or. PM? Please,.. Here is what I have on my home firewall.  I have not added or removed entries in quite some time… #"(http_inspect) JAVASCRIPT WHITESPACES EXCEEDS MAX ALLOWED" suppress gen_id 120, sig_id 10 #"(http_inspect) HTTP RESPONSE HAS UTF CHARSET WHICH FAILED TO NORMALIZE" suppress gen_id 120, sig_id 4 #"(http_inspect) NON-RFC DEFINED CHAR" suppress gen_id 119, sig_id 14 #(http_inspect) IIS UNICODE CODEPOINT ENCODING suppress gen_id 119, sig_id 7 #"BROWSER-IE Microsoft Internet Explorer userdata behavior memory corruption attempt" suppress gen_id 1, sig_id 16482 #"ET TROJAN Suspicious Malformed Double Accept Header" suppress gen_id 1, sig_id 2008975 #"GPL WEB_CLIENT PNG large colour depth download attempt" suppress gen_id 1, sig_id 2103134 #"FILE-IDENTIFY download of executable content" suppress gen_id 1, sig_id 11192 #"FILE-IDENTIFY Portable Executable binary file magic detected" suppress gen_id 1, sig_id 15306 #ET SCAN Behavioral Unusually fast Terminal Server Traffic, Potential Scan or Infection suppress gen_id 1, sig_id 2013479 #ET SCAN Behavioral Unusually fast Terminal Server Traffic, Potential Scan or Infection suppress gen_id 1, sig_id 2013479 #ET INFO Packed Executable Download suppress gen_id 1, sig_id 2014819 #(smtp) Attempted response buffer overflow: 1448 chars suppress gen_id 124, sig_id 3 #(http_inspect) UNESCAPED SPACE IN HTTP URI suppress gen_id 119, sig_id 33 #(http_inspect) TOO MANY PIPELINED REQUESTS suppress gen_id 119, sig_id 34

@somosane: Jim Thompson speaks about QI integration on his blog entry on https://blog.pfsense.org/?p=1724 Will the pfSense Snort packages have QI detection before upstream integration? Not sure how to interpret the blog post. I won't try to speak for Jim, but my guess is the answer to your question depends on whether or not QI detection is merged into the FreeBSD port of Snort before it makes it into upstream.  If or when that might happen, I have no idea.  I do know that pfSense likes to stay in sync to the maximum extent possible with FreeBSD ports. Bill

Thanks :)

Thanks everyone for their inputs, especially bmeeks . I recently purchase the gold subscriptions :) ,  time for me to do some reading before asking some noob questions. Cheers

Hello Bill, that would be nice ;) many thanks for your dedication.

Thanks doktornotor for the bug report.  It does appear I have some more work to do there with validation of aliases. Bill

Thanks fsansfil, yes i think youre right. All alerts came together and was shown as one. I will have a look at this and try to download again.

Great thanks! I just get nervous when upgrading SNORT as once there was a bug that would clear my block list when it wanted to no matter which option I choose for keeping the list.

Replied to you PM on this topic. Bill

I do recall seeing on the Barnyard2 Github page that OpenAppID events are not supported by Barnyard. Your new error seems to be related to the general issues the newer Barnyard2 code seems to have with SQL.  I became so frustrated with Barnyard2 and Snorby on my own home firewall installation that I just disabled Barnyard2 last month.  Got tired of restarting it and clearing the signature reference table and all the other hassles. Bill

Go to the RULES tab in Snort.  In the Category drop-down, select Custom Rules.  That will open a text window where you can type in your rule.  Click SAVE and you're done… ;). Bill

@Beerman: Had some troubles to update the package. Output of the installation process stops sometimes at "…waiting for snort to start...". Sometimes it stops at "... generating interface configuation...". Even the attempt to remove the package, was sometimes not successful. Output stops at some point. Second try, works... I tried several times the installation, but no success... Snort was running, but no entry in the web-config. Then I restarted "php-fpm", and use the IE (before I was using Firefox - v.38.0.5) and installation was OK and did not take long... I don´t know what helped... My guess is the change of browser, because on console I saw the whole installation process and snort did run after that, but the output stuck. Unfortunately I tried both together... :-( I checked again, today. Removing and installation fails with Firefox 38.0.5 Output at removing of the package stops at: Starting package deletion for snort-2.9.7.3-amd64... Output at installation of the package stops at: Please wait while Snort is started... But with IE11 removing and installing of the package worked. Installation took ~ 5 min.

All rules are logged exactly the same way in the same places (ALERTS tab and also the system log if you have that option enabled).  If you don't have alerts from your Snort VRT Community rules, then either none of the those rules have yet been triggered, or you don't have them actually enabled.  The Community set ships with the vast majority of the rules disabled.  You must enable the ones you want to use.  You do this on the RULES tab by selecting the Community rules in the CATEGORY drop-down and then enabling the rules you want to use. The IPS Policy rules do not false positive very often, so it is normal for them to be quiet. Bill

@SixXxShooTeR: increasing the stream memory cap from 32MB to 64MB fixed the issue. Yes, the old default stream memory setting is too small as of the 2.0.7 release of Suricata.  I will update the default size and make it some larger in the next package update. Bill

Thx for reply, ok i understand it now. But the Problem is, that the SRC is my dynamic external IP-Adress, which change ever 24h. So if i understand you right and i whould set the SRC for e.g. Downloads on the supress list, it would block after 24h again. Is it possible to show the real ip from internal lan and not only the external of my isp?

I fired up my VM again and changed every single editable setting on the LOG MGMT tab and they all saved.  I am unable to duplicate your problem.  Is there perhaps a caching server somewhere between you and the firewall that might be serving up a stale copy of the page?  Something like Squid, for example? Try clearing your browser cache and refreshing the page to see if the changes took. Bill

The specific character code I'm talking can only be seen if you view the data in a Hex Editor.  The character is "invisible" when viewed in plain-text mode.  It's a trick used to get IP addresses to wrap properly in the narrow confines of the table cells on the ALERTS tab.  I have code that is supposed to strip that out prior to "pasting" content into a Suppress List.  Perhaps for some reason that failed in your case, or there may be some other character in there. The Suppress List is encoded in the XML configuration as a Base64 string.  You can use an online Base64 decoder site to turn the encoding into regular text.  You can then view that regular text in a Hex Editor. Bill

Forget the last, I clicked on start WAN1 and both stayed on this time.  Weird.
