Did you enable Port scan detection?

General preprocessor settings section –> enable 'Portscan Detection'

Hello,

Suricata 3.2.1 is available on Fresh ports.

I saw this in the logs after the update:

/etc/rc.packages: [Snort] Removing all blocked hosts from <snort2c>table…
/etc/rc.packages: [Snort] Removing package files…
/etc/rc.packages: [Snort] Not saving settings… all Snort configuration info and logs will be deleted...
/etc/rc.packages: [Snort] Flushing <snort2c>firewall table to remove addresses blocked by Snort…
/etc/rc.packages: [Snort] The package has been completely removed from this system.</snort2c></snort2c>

Snort showed up in Installed packages with "newer version available". Tried to update:

Removed package. It threw some errors (attached). Rebooted.

Installed snort again without a problem. It now shows up in services and my settings are there too.

Have you tried turning it off and on again?

The only way that I could find to fix this, after serious testing, was to do a full reinstall, and restoring the backup configuration.

First thing of rule in security for me is never use someone else rules or whitelist. You as the administrator of your network should know it best and determine what is good and what is not. From your alert ip:

2017-02-23
11:55:30  3  TCP  Unknown Traffic  192.168.0.12
    88  192.168.0.10
    3871  120:3
    (http_inspect) NO CONTENT-LENGTH OR TRANSFER-ENCODING IN HTTP RESPONSE

Should .12 accessing .10? Is so then for what reason? Is it device or server compromise? If so did you check logs or do a wireshark capture? Things you need to ask.

2017-02-23
11:52:08  3  TCP  Unknown Traffic  151.101.124.84
    80  192.168.0.15
    34412  119:31
    (http_inspect) UNKNOWN METHOD

151.101.124.84 seems to be pinterest. Is .15 a device that is accessing pinterest at the moment is pinterest block? Content not showing? Most of the time http_inspect are errors with HTTP conversation. But not all the case, sometimes these can be some sort of consolidated attack on your servers or
possibly of trying to use them in an attack against another server or servers. In this case most likely not and consider safe if it isn't affecting the website or content I just leave it along. Hope that helps.

Yeah, remove and reinstall the package.

And why on earth is security software still using MD5?! :(

Thank you. I will try that when I'm back home. Out of the country for the next week.

Have you read the previous ~1356 threads about MD5 checksums mismatch?

HTTP 429 - server too busy. Stop hammering it, and wait a day or two before someone bothered to fix the checksums again. Yeah, nothing at all will happen meanwhile, it's not like the signatures would be updated every 5 minutes or it'd be the end of the world to not have the latest ones. Do NOT hammer the server 20 times per hour. That won't fix it. Broken checksums and server too busy are not pfSense package issues.

@OCKTechMag:

Ok. But what if…i mean just what if i want to use "Inline mode"?  :-\

My NIC 'em' is so called supported right? So why not HELP if you can to help me work it out?

But your response is snark-ish don't you think?

Whats the point of a TECH forum if folks seeking help are going to be meant with response as such?

Don't you THINK that like many people i know that 'legacy' mode is available and work?

Come on now!

What chipset your em nic use?

Hi pfBasic,

All that is needed is a Splunk installation and the app is installed on Splunk. I am running it on a standalone Splunk installation and running it 24/7. When Splunk and Snort for Splunk is installed, the app is viewed through any browser that connects to the Splunk server. I haven't tried using Splunk and Snort for Splunk on a VM, but I can't see why it shouldn't be installed on a VM. The setup for the Splunk and Snort for Splunk would be:-

1.) Install OS of choice (Windows, Linux, Mac OS X, Solaris, FreeBSD(?)). I don't know if there are still versions of Splunk available for FreeBSD.
2.) Install Splunk Enterprise and get a free licence.
3.) Connect to the Splunk server via the IP address (eg. 192.168.0.1:8000).
4.) Install Snort for Splunk from the SplunkBase through the web interface of the Splunk server and start monitoring the Snort logs.

That's about it.

Hope this helps.

At this point we can reliably recreate blocked traffic that is dropped in suricata and when we disable a specific category it starts to flow. But there is still no alerts in the log for that traffic or from that IP. But trying to find the offending rule when there is no alert and 1000+ rules in the category is next to impossible.

Disable a category at a time to find the right one is not a nice way to find a offending rule.

The only thing I can think of is the rules with "noalert" in them. @BMeeks Could these rules be the culprit? Can we get dropsid to take these rules into account and not add a drop to them ?

Awesome, got it. Thank you!
