      updated this morning and now snort fails to start with this:

        Had the same issue.  Fixed it at least for now by:
        1. uninstalling snort
        2. from command line find / -name snort
        3. rm -r all files left from snort found from the above command
        4. reinstall snort.

          If you uncheck that specific list of rules snort will start, but I am still having my current issue with the preprocessor error. Any idea on how to resolve this?

            @dwood: had the same problem.

            Just removed and reinstalled with the latest binary and all is working again.

            @ermail: is it possible to add the snort build number/date somewhere in the GUI? This way everybody nows exactly where they are.

            This is an excellent suggestion.

              Hi,
              anyone for the local IPs blocked when "block: both" is selected? Am I the only one having this issue?

              Thanks,
              Michele

                  Ok, thanks. The important is that this issue is known and shared, because if I am the only one I have to ask myself what I am doing wrong…

                        @ermal:

                        I pushed a fix to the sensitive data rules.
                        Please test it after 30 minutes.

                        @ermail: is it possible to add the snort build number/date somewhere in the GUI? This way everybody nows exactly where they are.

                        I would prefer not since its not needed and you are just reporting bugs here.

                        Ermal this is still not fixed.

                        If snort is running and downloads a new rule update then tries to apply it, the same will occur. I have the latest version update.  Of course if I uninstall snort and reinstall it will start again and run fine but it is still not fixed as the next rule update will cause the same error.

                        A reinstall and snort will still not start with a different error:bad-traffic.so <-  This rule is not even enabled.

                          I am getting the same error. If I let it auto update this happens without fail. If I have the package removed and installed fresh, and manually update the rules I do not get this error. I do not have the sensitive data option enabled in the preprocessor section. (havent enabled it since it was an option on that tab) I generally do not change my rules/categories or options. They have been the same as they have been for a year or so now.
                          I am on the latest pfsense build that I can grab (official) and the latest snort version that has been pushed. FOr now I have disabled the auto update since its more important for me to have snort running at the moment rather than erroring out and not running due to this.

                              same problem here:

                              i fixed it by doing this:

                              added the line: config classification: sdf,Sensitive Data was Transmitted Across the Network,2
                              at the end of: /usr/local/etc/snort/classification.config

                              and disabled auto update for now

                                I have two installations working fine, (2.0.1) and autoupdates set for every six hours for testing.  So far so good..however the error may return when the rules are actually updated.  I suspect that there are no new rules yet which would have triggered an actual update.

                                EDIT:  Yep, an update (emerging threats) triggered same error.  Removed, erased snort bits, reinstalled and started fine.  Turned off updates for now.  The good news is that snort is behaving and blocking just fine otherwise :-) Thanks Ermal.

                                Btw, the WAN blocking issue has not re-occurred on two AMD64, 2.0.1 installations.  Important to note that snort should be uninstalled, then run "find /* | grep -i snort | xargs rm -rv" , then reinstall.  This ensures you get a new SNORT binary..at least for now, reinstalling won't replace the SNORT binary file.

                                Cheers,
                                Dennis.

                                  Should behave better if you just reinstall.
                                  No new binary needed.

                                    After reinstall I got

                                    After complete reinstallation snort rules download failes. Not even the md5 file gets downloaded.

                                    php: /snort/snort_download_rules.php: Snort rules file downloaded failed…

                                    Maybe snort server is down...but I get message that there is a new set available.

                                    EDIT: 7 hours later and after another reinstallation snorts starts up without error and snort.org rules were downloaded. Everything seems to work so far...

                                      Can anyone tell why this is missing after auto rule update:

                                      added the line: config classification: sdf,Sensitive Data was Transmitted Across the Network,2
                                      At the end of: /usr/local/etc/snort/classification.config

                                          It's so close now…  I'm still on 2.9.1 and waiting for the list of issues to die down and I can see it's almost there.   
                                          Just wanted to thank all Ermal AND all the users doing the testing.  Everyone's help is appreciated by the rest of us.

                                            ^^^ he was the smart one  ::)

                                            all my testing is on my home box, so i dont care if it breaks here and there… now the wife on the other hand is a different story... But she is best user tester... I know within seconds if the internet is down... In this case, snort blocking facebook or pinterest because it didn't like the http packets that were sent over..
