      Overall that's a great implementation for log file rotation.  Thanks!

      What is the timestamp based on?  Not possible/practical to make it a more 'human recognizable' YYYYMMDD…  value?  Would just make it easier to identify the file with the time frame you are looking for.

        The timestamp is the vanilla UNIX timestamp (the number of seconds that have elapsed since midnight January 1, 1970).  I used that format because that's what Suricata does for the other logs it does rotate on its own.  I figured consistency with the other logs would be the best way to do it.

          First, I'd like to apologize if my comment is incorrect. I am not the native english speaker.  The tabs "Check" and "Force" have the "opposite" meanings for me. If you want to just "Check" the program shouldn't download anything, just notify me.

            ?! Erm, maybe it is considered to be Update&Upgrade meaning updating the rules and upgrading the software accordingly ?!

              The two buttons were intended to work this way.  Your comment about "checking" versus "updating" is valid, though.

              The original behavior was to download the MD5 hash from the publisher's web site and compare the hash to the locally stored hash for the current rules package.  If the hash codes matched, nothing else was done.  If they did not match, new rules would be downloaded and applied to all running Snort processes (according to the specific rules enabled for each process).  There were occasions when a "bad" rules package would be downloaded but the MD5 hash file was OK.  In this situation, in order to get a fresh uncorrupted rules package, a manual edit of the MD5 hash file was required to "force" a mismatch in hash values so a new package would download.  This is what the new FORCE button does.  It downloads a fresh rules package without testing the MD5 hash first.

                Is there a trick to getting Suricata to start?  (Do I need to reboot, for example?)

                The documentation doesn't make this clear and I'm currently unable to start Suricata by clicking on the red "X" icon, I get this in the logs:
                Apr 14 18:07:38 pf1 php: /suricata/suricata_interfaces.php: Toggle (suricata starting) for XXX(Xxx Internet)…
                Apr 14 18:07:42 pf1 php: /suricata/suricata_interfaces.php: [Suricata] Updating rules configuration for: XXX …

                Apr 14 18:07:49 pf1 php: /suricata/suricata_interfaces.php: [Suricata] Suricata START for XXX Internet(igb6)…

                but then it returns to the config screen with the red X still present and no suricata processes running.

                I'm running 2.1-RELEASE on 4GB Nano.

                  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.

You are on the latest version.

                                  Any pointers?

                                  Thanks

                                  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.

                                            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.

                                            6 and a half billion people know that they are stupid, agressive, lower life forms.
