      Well, I seem to be able to make all the settings, update rules, etc.
      The interface is listed as enabled, as is snort, except: if I start snort, it will never show as running e.g. on the Dashboard's "Services Status" list. Similarly, the green "start" icon is always next to the interface, no matter how often I start the service there.

      So something seems to be a bit busted, unless snort is allergic to the fact that all my traffic leaves the system through an IPSec tunnel, which makes me wonder what Snort will even detect when I have it set up on the WAN interface, given that I cannot select the IPSec as the source to monitor.

        I have tried numerous times but have never been able to start snort. Exact same settings work on 2.0.1. Even a clean 2.1 install makes no difference. Always get some pf_alert issue. Tried re-installing on top of existing install too.

        I really want to start using 2.1 dev builds but don't want to opt out snort. Feel a bit secure with snort on my firewall.

              Any updates on this did you try to use ssh to connect to pfsense and type in snort start and post the out put you get ?
              Does anyone knows how to solve this error : Can't set DAQ BPF filter to 'start' (pcap_daq_set_filter: pcap_compile: syntax error)! This prevents me from starting snort.

                  Check my second post in this thread. That is exactly the error I am getting. I was not able to start snort even through SSH.

                    Any progress on this?

                    I checked with a clean install again last night. Same issue with Snort.

                      this may work… install the package log into the box via ssh. run

                      pkg_add -f http://files.pfsense.com/packages/8/All/snort-2.9.0.5_1.tbz

                      goto gui, update rules and see if it starts... make sure all the per-processors are checked..

                        Isin't that an older package? Is it compatible with the latest pfSense FreeBSD version?

                          it should work.. it worked for me a month ago when i tested 2.1 binaries… Remember that packages are built for the stable version of pfSense. The pfSense package is built around snort 2.9.0.5_1 binaries

                            How is this going to affect future updates, both of the packages and/or the OS or snort?

                              you would have to reapply it… i'm hoping once 2.1 is released, that snort will also be updated.

                                iirc a few months ago there was a monetary donation earmarked specifically for Snort, to finally integrate it with pf (ala spoink, snort2c, SnortSam etc). Perhaps do a new round of "crowdfunding" to finally get this done?

                                  i remember donating for that…... not sure what is left from the pool... but If I was PMing pfSense, i would want to get 2.1 release first...

                                    There is something interesting the snort package provided by 8.3 free is older than older freebsd version stable version 2.9.2.3

                                    Is pfsense 2.1 build on old packages ? It seems that when I try to install something on pfsense it states that needs newer packages

                                        install the pfsense snort package first via the gui…. then drop down ssh and run the above command

                                        this will overwrite the binaries that were installed from the pfsense snort package

                                          Tried that too. Via SSH it downloads the package but does not install it.
