      @Fesoj:

      Are there any clues in the system log (Status: System logs: System)?

      Hi, yes, there seems to be the generic 'version mismatch' errors:

      Jul 5 14:11:17 snort[937]: FATAL ERROR: Failed to initialize dynamic preprocessor: SF_DCERPC version 1.1.5 (-1)
      Jul 5 14:11:17 snort[937]: FATAL ERROR: Failed to initialize dynamic preprocessor: SF_DCERPC version 1.1.5 (-1)

      Current snort version is:

      snort -V

   ,,_     -*> Snort! <*-

      This seems pretty generic, and I'm not sure of the 'right' way of fixing this in pfsense

        from the console shell go to:

        /usr/local/lib/snort/dynamicrules

        Delete anything in this directory

        Start snort from the Gui.

          Saw that on another post but…there's nothing there:

           pwd && ls
/usr/local/lib/snort/dynamicrules

          :(

            I am sure you did but I have to ask, you did click on the update rules in the gui after the install and also select an interface for snort to run on and finally selected rules to apply to the interface correct?

                same issue here:

                starting snort from gui doesn't work. logs show this (end of log):

                Jul 6 12:58:02	snort[37407]: Search-Method = AC-Full-Q

                /usr/local/lib/snort/dynamicrules is empty -> have installed rules before!

                  On the interface IF settings tab at the bottom is there anything in the advanced configuration box?

                  Also is this a i386 or a amd64 build

                    @mschiek01: Nop, nothing in there. Redownloaded the rules, but same as before: pidfile empty:

                    /usr/local/etc/rc.d/snort.sh start
                    pgrep: Pidfile `/var/run/snort_pppoe016197.pid' is empty

                      You didn't say if this is a 64 of 386 build.  If it is a 64 build make sure you did not select any .so "shared object rules" on the categories tab of the interface.

                          You can try this:
                          Edit this file
                          /usr/local/etc/snort/snort.conf

                          and comment out line #254 'dynamicengine /usr/local/lib/snort_dynamicengine/libsf_engine.so'

                          then see if it starts.

                            Did that, but same message appears:

                            /usr/local/etc/rc.d/snort.sh start
                            pgrep: Pidfile `/var/run/snort_pppoe016197.pid' is empty

                            :(((

                              can you try to start snort from the gui and then post your system log?

                                The pidfile empty message is a normal error just put the system log here to know what is happening to your setup.

                                  Found it!

                                  The system-log had additional enties which were not shown in the gui:

                                        Reinstall snort

                                        Start snort and post the system log if it does not start.

                                          With a clean AMD64 install (did not save settings, uninstalled, executed "find /* | grep -i snort | xargs rm -rv" command, rebooted) and valid oinkcode, a rules update is attempted.  The Updates TAB indicates that no emergingthreats.net or pfsense.org signatures are installed.  The "Install Emergingthreats rules" option is however toggled on under the Global Settings Tab.  During an update, the status message is that Emerging Threats rules are up to date..although they are not present in the interface Category Tab.

                                          Unlike the previous attempt (clean install, but had "save settings" toggled on from 2.2.2), this time Snort 2.2.3 does start successfully with all rules (except emergingthreats which as described above are not there) enabled.

                                          The issue of Alert Description displaying "N/A" remains..not sure if it's on a fix matrix or not..

                                          Cheers,
                                          Dennis.

                                            Uninstall snort

                                            Delete /usr/local/lib/snort/*

                                            Reinstall snort

                                            Start snort and post the system log if it does not start.

                                            Looks like that did it - I suppose we'll never know what was really wrong. Thanks!
