      Ermal,
      I checked again today and I am not seeing anything in the sys log about the auto update running or not running. If I run manual update i see the entries. Also I have removed blocked hosts after 6 hours and snort hasnt been doing that. I just changed it to three and restarted the service to see if something was glitched. Will monitor to see if that is working properly. Not sure if its isolated to just my setup or not. Just wanted to mention it to see if anyone else has had the issue.

      Can you check /etc/crontab if it has the entries for snort?

      I pushed a fix which should help here.
      Just resave yor settings on Global tab.

      Here is what cron is showing. Looks like no time settings are entered. Looks like the remove host is doing the same thing as its blank too.. May explain why they arent being removed like they should.

        I am not seeing the update on the dashboard… Guess it takes a while to recognize.. Will check back on it.. What version number is it up to now?

          You need to have an alias cannot put ports there.

          I wild guess about the suppression is a missing revision?

          Why an alias when the specific ports are needed??

          By the way, running on 2.5.4 so unless package has been updated, then I am on the latest revision.

            No the version has not been bumped since some small fixes will come still.
            When those are finished ti will be bumped.

                Hi,

                I have the issue with the lib mysql.18 which I was able to correct with pkg_add -v -f -F http://files.pfsense.org/packages/8/All/mysql-client-5.5.29.tbz

                But when I reboot my VM, I have to do the command again, because snort won't start with my interfaces.
                It is very weird because before rebooting everything was working perfectly fine, alerts were there, all interfaces were enabled…

                Anyone has an idea ?

                Thanks in advance

                  It seems very weird because if I create a folder, after rebooting it is still there, but a modifications like the package is not working.

                  I suppose pfsense or Freebsd is blocking my modifications, is it possible to force the modification or disable the thing which is unabling me to saves changes ?

                  Thanks in advance

                    Are we seeing the end of this when Ermal/Bmeeks committed the last changes or do we have to wait until the package is bumped to 2.5.5??? So far running fine here, but havent upgraded to the last snaps from Ermal. Running the changed files from Bmeeks.

                        The "big pieces" for this update cycle are done, I think.  My main focus was getting auto-flowbit resolution working and integrating the VRT Policy rules selection.  Along with those main goals were some incidental fixes like the stream5 preprocessor memcap setting and some items related to http_inspect.  At Ermal's request, the last change was some code to automatically scan for and disable any rules in the selected rule sets that depended on disabled preprocessors.  This is necessary because certain preprocessor-dependent rule options (such as the ssl_state and ssl_version options associated with the SSL preprocessor) will cause Snort to error out and not start if the associated preprocessor is not enabled.

                        In my view, the next "big piece" is to update to the latest 2.4.x Snort binary.  I am not ready to jump out there and start that project on my own, though.  Still not experienced enough with the pfSense/BSD platform and its package building tools.

                          I'm still seeing a minor oddity when updating to a new snapshot of 2.1 and snort being re-installed during the reboot. When pfSense is all up and running, snort would show as running and presumably does have some rules to use, but the updates tab shows no rules installed. I have the "Keep snort settings after deinstall" option checked.

                          So in summary:
                          Snort re-installs fine
                          Snort is blocking offenders after re-install
                          But Updates tab shows no rules installed

                          Also the "Update log" button seems to still be broken. It's not inactive / greyed out anymore, but it doesn't do anything when clicked.

                            This is a problem that likely can be fixed, and I will take a look at getting the button working.  One small complication here is that the Update Log is only created when the automatic update cron job runs.  The log is not created during a manual update.  Basically what happens currently is the console output of the cron job rule update is redirected to a file in the /tmp/ directory.

                              Help! Snort will not start from the webgui after update to pfsense 2.02, currently running snort 2.9.2.3 pkg v. 2.5.4.  GUI reports service is stopped so I attempt to restart and it just stays stopped.  Individual interfaces respond similarly.  I have tried reinstalling snort as well, no dice.  I tried suggestions on this thread as well to no avail : http://forum.pfsense.org/index.php?topic=58175.0 .  Snort seems to start by simply typing "snort" in shell but webgui doesn't respond.  Any suggestions would be appreciated. BTW, I have read the thread and it seems this problem is ongoing, is it just best to wait for version 2.5.5?  Is snort really running and just not reported in the GUI?  Thanks in advance for your help.

                                Did you look at your log? You shuold post error messages you are getting in log. Snort works fine fine with 2.1

                                  I have copied the results of my log below. BTW, did you mean 2.01? Because version 2.1. Version 2.1!  Great Scott! In the future I bet anyone can get version 2.1 at the corner drugstore, but here in 2012 it's a bit hard to come by.

                                        First thing to check is that you actually have some downloaded rules.  That missing file is part of a rules update package.  Just to be sure, do a rules update from the UPDATES tab.  That should force everything to be created and copied to the correct places.

                                          Thanks Triton,  that link helped.  It's not fixed yet but it looks like the problem is the conf file is looking for the unicode.map file and it's missing.  I'll have to find it and cp it over.  BTW,  bmeeks, I have tried reloading the rules as well as comlete reinstall a couple times, none of this helped.  snort(interface).conf is corrupt.

                                            SUCCESS! THANKS TO TRITRON for putting me on the right track!!! Steps to recover from the unicode.map error

                                            1.) make a tmp directry and fetch the latest snort there. It's currently available from: http://www.snort.org/dl/snort-current/snort-2.9.2.3.tar.gz

                                            2.)untar the file above ie:
                                            tar -xvf snort-2.9.2.3.tar.gz

                                            3.) locate the unicode.map file:
                                            find / -name unicode.map

                                            4.) copy the file found above to the location the logs say it was missing from:
                                            cp snort-2.9.2.3/etc/unicode.map /usr/local/etc/snort/snort_46603_re0/

                                            5.) restart snort from GUI and VOILA!

                                            Thanks guys.  The only bad new is now I have to redo my snort configs for my LAN and DMZ since I removed them thinking that would help.  O well, maybe I could just increase the mem profile on the WAN.
