Hi Bill,

many thanks…

Dirk

Which file are you editing?  When I directly edit the config, I use the file /conf/config.xml.  I navigate to the file using Diagnostics > Edit File.  It is living dangerously to directly edit the production file, but since mine is a home system I take the risk.  I don't know why your changes are getting overwritten.  I've never had that happen to me.

I think there are some hoops to jump through if you import or copy in a new config.xml file itself from a remote source.  The contents of the file are saved in a large global memory array.  Perhaps something is triggering a "dump" of the in-memory data back to the file and thus overwriting the changes you just made.

@NetDefense:

OK I did some digging and figured that out. Your post now makes sense to me now that I know what emerging threats is.

I did notice this post is kind of old and when I take a look at the RBN rules and it appears they are no longer updated. http://doc.emergingthreats.net/bin/view/Main/RussianBusinessNetwork

The RBN list has been discontinued for awhile now… The only two free lists available from Emerging Threats (now Proofpoint) is ET Compromised and ET Block....  With the ET IQRisk suite (Paid subscription) they have an IPRep list available...

Create an extra DMZ and place the server inside of this then. Set up snort scanning on your LAN port.
So the Server will have Internet connection and the rest of the LAN will be scanned by snort.
WAN - NAT and pf
DMZ - Snort is not scanning
LAN - snort is scanning

Ok great.  THank you Bill.  I can definitely live with that!

thanks for your reply, I already tried that, but it didn´t work out, there are a number of configuration files that need to be updated, but I could not find  which ones and what to write

Did it !  :D  Great !
In effect, I only intend to set up Suricata for the moment.
Thank you a lot !

I tried to put only the adresse and i have change de port from 514 to the pappetrailapp port and I have opened this port in firewall and it doesn't work. I want to try again.

Multiple instances happens sometimes when the pfSense core code sends more than one "restart packages" command in a short time interval.  This can happen, for instance, during a WAN IP update caused by DHCP (if you have that configured on the WAN side).  There are a few other triggers of the "restart packages" command.

Hi guys, this topic really helped me, but in my case the solution was create two databases, one for each Barnyard instance (i have two monitored interfaces), no more "Duplicate entry" now, thanks!

Finaly i found the solution. I have create a supress list and then apply to the interface then restart snort. I have find a youtube video.

@bmeeks:

You could safely disable that rule if you wish.

Bear in mind that if you decide to allow HTTP traffic on 443, all the rules with $HTTP_PORTS wont be inspecting that traffic. Unless you add 443 to the $HTTP_PORTS variable, which will cause other false positive with some HTTPS inspection. In other word, the way alot of rules are made, HTTP, non encrypted traffic,  shouldnt be on 443

Thanks for your reply.

That makes perfect sense. Hadn't thought it through enough…

Happy Holidays,
John

Hi
Thank you for the reply,
Well…did not really understand on what you mean I been trying to follow this guide
http://www.moh10ly.com/blog/pfsense/configuring-snort-on-pfsense

All I would want lets say i open port 443 webgui and someone tries to access many times eventually it gets blocked that IP as it shows on the guide But i was not able to get it working.

Not sure if I add all the rules?

And not sure what is this unknown rule http inspect

See pics

Thanks you

Good to know!

I have disabled those rules for now but I feel there is still some cleanup to do before I get snort running smoothly and not act crazy on every bit that comes & go from my LAN.

Another think for people micromanaging the rules:  we can remove "Enable/Disable" changes in the current Category, remove all Enable/Disable changes in all Categories (good if you want to return to the stock ruleset), disable all rules in the current Category, enable all rules in the current Category (those two are good to enable/disable all rules quickly), but there is a missing filter to display only specific sets of rules, for example all rules that were manually disabled or enabled, all rules currently disabled or enabled, etc… and a filter to search rules by SID would be great as well... especially during a fatal error..

No problem here in the USA with Snort VRT updates.  Here is the log output from just after midnight Eastern Standard Time today –

Could be (or could have been) a temporary condition.

That's not really ideal to be honest :(, but thank for the idea!

It's really really annoying that Snort can't do this easily

The alerts are just DNS queries for .pw and .su domains. Often related to torrents webpages, like piratebay.su. You also need to make sure your dns servers, specially 8.8.8.8 is in your HOME_NET of your Snort interface, otherwise if you chose block offenders and select "both" in the which IP to block, your DNS server will get block with those alerts, therefore not allowing any external DNS…. Check if your DNS servers are in the blocked tab of your snort interface.

As for the SNMP, make sure your firewall is configure with some permission to access this service, only allowing your specific IP.
