Suricata IDS 1.4.6 BETA package update v0.3 released

@ScottCall:

@BBcan17:

Did you perform a Rules Update? If not, that needs to be done first before it will start.

Yeah before I configured the interfaces and tried to start.

Thanks

Goto the LOGS MGMT tab and open the suricata.log by selecting it in the drop-down selector to view the contents.  See what errors are in there.  Suricata logs it's stuff to its own private log file.  Report back if you see something in there.

Thanks Bill.

I checked under the "Logs Browser" and none of the logs exist, they all return "Log file does not exist or that logging feature is not enabled."

I'm using ETOpen, Snort VRT (free registered) and Snort GPLv2.

I'll schedule some time to reboot the firewall to see if that's what it needs.

Thanks

Whoa!  That's certainly not right.  The suricata.log file should always exist as it is created with any attempted start of Suricata.  Something is seriously borked with the Suricata install is my suspicion.  A reboot and possible reinstall of Suricata would be a good start.

EDIT UPDATE: just re-read your original post and noticed the NanoBSD mention.  I overlooked that previously. That could be the problem.  There may be some problems with Suricata forgetting to put the file system in R/W mode before it writes configuration information.  I did all my development and testing on regular installs with hard disks (well, virtual hard disks in VMs).  I have not tested Suricata on something like NanoBSD.  You also may not have enough RAM to run Suricata and pfSense.  You said 4 GB, so I assume that is total CF capacity.  The OS is going to take a bit, and then Suricata gets what's left over.  That is not going to be much.

I did the nano install to try pfSense over the existing (commercial, expensive and outdated) install on the boxes.  I've been planning on converting them to HDD based installs anyways, so I'll hold off on suricata until then.

Thanks!

It should work fine on a conventional HDD (or SSD) installation.  Unfortunately, I don't have a CF system to test with.

Have not seen that error before.  This essentially means the protocol on the interface is not supported by Suricata.  Let me first ask you to try the old standard technique of removing Suricata and reinstalling.  Before doing this, go to the GLOBAL SETTINGS tab and check the box near the bottom of the page to retain Suricata settings when deinstalling.  Save that change and then remove the package under System…Packages from the pfSense menu.  When removal is complete, install it again.

Please report back on the result.  Also, can you post what the interfaces are you are using Suricata on?  By that I mean vanilla Ethernet, or maybe something like PPP or some kind of tunneling interface?

Remember to reboot after deinstall….before you install it again!

Remove and reinstall done - no change - still get the error when using the WAN interface.

I have created a LAN interface mapping, and it works just fine.

The WAN mapping is a PPPOE interface - looks like that type is not yet supported.

Here is the log for the working LAN interface ( type em0 ):

@Gibbon_99:

Remove and reinstall done - no change - still get the error when using the WAN interface.

I have created a LAN interface mapping, and it works just fine.

The WAN mapping is a PPPOE interface - looks like that type is not yet supported.

Here is the log for the working LAN interface ( type em0 ):

Yep, that is the problem – PPPoE does not appear to be supported by the underlying Suricata binary.  I will research to see if there is anything I might could do to address this.  I seem to remember some folks using Snort just fine on a PPPoE interface, and Snort and Suricata both are using the same libpcap library on pfSense.

I have one of my pfSense boxes on ppoe with Snort for over a year without any issue like this. Just an FYI.

[Mr. Jingles]

I can confirm I have the same problem, my log is flooded with this:

suricata: 14/6/2014 -- 12:13:21 - <error> -- [ERRCODE: SC_ERR_DATALINK_UNIMPLEMENTED(38)] - Error: datalink type 0 not yet supported in module DecodePcap</error>

This might perhaps also explain why I don't see any hits on WAN (VDSL2) (but also not on WAN2 (Cable), for that matter), but quite some on LAN.

Suricata 1.4.6 pkg v1.0.3

It runs on VDSL2 (PPPoE), Cable (DHCP), and LAN.

Snort, which I ran for over a year did not show these errors. I only switched to Suricata yesterday as smart people in here recommended to do so.

[Cino]

I'm trying to setup Suricata basically the same way I have snort configured today and I may have found an issue or maybe the snort code wasn't carried over.

Home Net and External Net are not pulling from 'Pass Lists' tab like they do in Snort. Only the Pass List area is able to pull from the list in Suricata..

Another issue I found is in the Alert log… In Snort, IPv6 address are compress if there are a bunch of 0:0:0... So an address may look like 123:345:567::1. In Suricata, they are displaying like 123:345:567:0000:0000:0000:0000:1..  Hopefully that is something that can be fix

thanks again!!

It seems suricata has the same issue with the IPv6 link-local address as Snort has.
The default home net has the external link-local address with the interface reference in it.
This results in an error when parsing the home nets.

Using snort I can supply a home list and an external net by creating an alias.
On suricata I can create an alias but it will not show up in the drop-down list.

When looking in suricata_interfaces_edit.php I see the drop-down is populated using a passlist, however I cannot create a whitelist but only a passlist (used in the alert suppression).

@avink:

It seems suricata has the same issue with the IPv6 link-local address as Snort has.
The default home net has the external link-local address with the interface reference in it.
This results in an error when parsing the home nets.

Using snort I can supply a home list and an external net by creating an alias.
On suricata I can create an alias but it will not show up in the drop-down list.

When looking in suricata_interfaces_edit.php I see the drop-down is populated using a passlist, however I cannot create a whitelist but only a passlist (used in the alert suppression).

                                echo "<option value="default">default</option>\n";
                                if (is_array($suricataglob['passlist']['item'])) {
                                        foreach ($suricataglob['passlist']['item'] as $value) {
                                                if ($value['name'] == $pconfig['passlistname'])

I think you have indeed identified a bug in the code.  I'm sorry that one slipped by me.  I only recently obtained an IPv6 tunnel broker setup so I could test IPv6 in the flesh instead just in a limited VM world.

I will add this to my TODO list of fixes for Suricata.  I am currently working on moving that package to the 2.0.1 Suricata binary code base, so please be patient with me a little bit longer.  If I run into any significant delays with the 2.0.x update, I will push out a fix for this and several other reported bugs in a 1.4.6 binary update.

bill, thanks again for all the work you have done with suricata and snort.

not sure if this is on your todo list, but take a look at how the below alerts are displayed in the gui:

i'm pretty sure its because of the comma in the alert description. pushed everything over a column.

Modified suricata_interfaces_edit.php to be able to use the Home Net alias.
Also modified the /usr/local/pkg/suricata/suricata.inc to remove the interface reference from the link-local address.

Now suricata neatly generates the configuration file.
However, since I'm running over a PPPoE link, the syslog is filling with the 'datalink not supported' errors.

I hope we will find a solution for this too.
Snort is running without problems as mentioned by others also.

Ouch!  That's going to be a tough one to fix.  The whole premise of parsing the alert text is based on splitting the fields on the commas.  I'll have to chew on that one.

Yes, that should be fixed from the other end.
