      When I run the start script manually I get:

      /usr/local/etc/rc.d/snort.sh start
pgrep: Pidfile `/var/run/snort_sis01697.pid' is empty
pgrep: Pidfile `/var/run/snort_vr08627.pid' is empty

      If this were linux I'd have a pretty good idea what to drop into those files but…I'm a pretty big noob when it comes to bsd :)

      There's obviously a problem with my config/script, but I don't know what to add to those PID files.

      Running it manually it listens on sis0 without issues:

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

          @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

          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.

                            oh, sorry. Its amd64 and i have no .so rules activated. Looked twice to be sure.

                              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.

                                /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.

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

                                            Uninstall snort

                                            Delete /usr/local/lib/snort/*

                                            Reinstall snort

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