      Just check to see that your rules and preprocessors are enabled.

        Updating the package and the rules work, but starting up fails with this message in the system logs:

        snort[10689]: FATAL ERROR: /usr/local/etc/snort/snort_2791_em0/snort.conf(120) => Failed to parse: No end brace found

            Heh fixed the ssl port definition of ports.
            I had tested it with custom SSL ignore range.

            Anyway in 15 minutes will be safe to upgrade and issue will be fixed.

              @miles267:

              ugh.  snort seems to get progressively worse with each build.  hasn't functioned reliably in months.  next time I get it to work, no way I'm updating again.  now:

              Thank you for helping in testing.

                Updated to: Snort 2.9.2.3 pkg v. 2.4.1

                Noticed that no matter what I enter into the If Settings > 'Advanced Configuration Pass Through' dialog box, it gets converted to a string of random characters.

                For example, if I enter: portvar FILE_DATA_PORTS [$HTTP_PORTS,110,143] and SAVE.  When I go back, it will then display in the same dialog box:

                cG9ydHZhciBGSUxFX0RBVEFfUE9SVFMgWyRIVFRQX1BPUlRTLDExMCwxNDNd

                Also, despite entering: 443 563
                into the Define SSL_IGNORE dialog box, snort still will not start.  And returns the following:

                snort[26571]: FATAL ERROR: /usr/local/etc/snort/snort_9414_em2/snort.conf(54) Missing argument to SSL_PORTS_IGNORE

                  Fixed also.
                  Again test after 15minutes.

                    @ermal:

                    Fixed also.

                    OK - great.  Will there be a 2.4.2? or have you already fixed 2.4.1?  I've re-installed 2.4.1 as of 7:30 PM CT but the same issue persists.  Perhaps I updated too soon.

                      install went well but snort isn't alerting. Usually a common port scan from https://www.grc.com/x/ne.dll?bh0bkyd2 will generate an alert

                        Reinstall with latest fixes it should behave better.

                          deinstalled snort, installed it newly, did a reboot after updating, snort started, but still no alerts nor blocking… :(
                          But at all the overhaul was great! Behaves much better!!!!

                          edit: snort started reporting alerts, but still no blocking :(
