      Why does the package reinstall doesnt work, but the package delete- reinstall does?

        It should work after updating to 2.5.4 previously it was removing some files that were not being restored after an update.
        There is some resolution missing for enabled disabled preprocessors.

        After you get it running it will run ok.
        I will have to find some time to get back to solve this last bits and making it less error prone to this install/reinstall and using rules when the preprocessor is not active but for now you just have to find the preprocessors needed and activate them.

          So far I havent had any issues with the updated version. I am guessing the auto update worked fine as snort was still running this morning. I dont see any snort reload items in system log. (to be expected with the verbose items being turned off) Not sure if there is a way to find a good compromise of leaving all the other stuff off but still showing with the update runs and if its successful.

          Thanks again for the quick fixes on the problems yesterday.

            @tester_02:

            Updated snort today, now it does not start.  Error is…

            snort[4286]: FATAL ERROR: Failed to load /usr/local/lib/snort/dynamicrules/bad-traffic.so: /usr/local/lib/snort/dynamicrules/bad-traffic.so: Undefined symbol "freeRuleData"

            I disabled the bad traffic rules (so and non so) and it still fails to start.   reinstalled package again, and no go..   Was working for quite a while.  Had not updated for a month, but thought from the thread here that it was stable.

            I got this too. I had to delete snort, do a find all for snort and remove everything until nothing was returned. Then i reinstalled snort and configured. So far so good!

              Normally you should have the logs from the update process itself.
              Something like "Starting with your new set of rules…."

                I dont see this in the system log. When I go to the updated tab in snort the view updates log button doesnt do anything when clicked. I did a manual update and did see this in the sys log
                Jan 27 11:49:12 php: /snort/snort_download_rules.php: The Rules update has finished…
                Jan 27 11:49:12 php: /snort/snort_download_rules.php: Emerging threat rules are up to date...
                Jan 27 11:49:12 php: /snort/snort_download_rules.php: Snort rules are up to date...
                So i am guessing if the auto update ran I should see something similar? I do not see anything like this around midnight when the update generally runs.

                  Having issues with the latest snort package as well. Initial update killed the package. Uninstalled, did a reboot and reinstalled to make it work. But now the problem is with every reboot snort fails again. As long as its up after reinstall it works. Upon a reboot snort fails and only way to make it work is to uninstall, reboot and reinstall… till the next reboot.

                      You need to reinstall supermule or you have issues.
                      It will only print fatal/errors as i said now. Those things need some attention.

                            There is no failure there.
                            The error messages there are just too much noise.

                              Well I dont see any other logs in there.. It just fails to start. I am on a VM but that shouldnt be a an issue. Been using a VM for many months with no such issues.

                                Assuming this is the proper way to start snort from the prompt, you would see the following error:

                                /usr/local/etc/rc.d/snort.sh start

                                  Snort needs to be started automatically when pfSense boots. Even so the GUI service start should throw some errors.

                                  The latest package definitely needs a fix.

                                    Hrm that is a problem with the building of the package.
                                    barnyard2 requires mysql but snort does not require it.

                                    Will see to get it fixed. For now just install this mysql-client-5.1.53.tbz
                                    i386

                                    
pkg_add -v http://files.pfsense.org/packages/8/All/mysql-client-5.1.53.tbz

                                    AMD64

                                    
http://files.pfsense.org/packages/amd64/8/All/mysql-client-5.1.53.tbz

                                    For 2.1 PBI should include that

                                      I run mine in VM too…. So it shouldnt be a problem.

                                        Hi,

                                        The uninstall/install after reboot happens on my machine as well, with the same errors…

                                        Another thing - I don't think HOME_NET is being populated correctly on my machine. On my LAN interface, instead of including my network it only includes pfSense IP (and my external IPs, DNS, etc) . I've ended up editing snort.inc and manually adding my network address but I guess this will hold only until next reboot and reinstall. Older posts mentioned the possibility if using the firewall aliases, but I can only choose "default" at the "Home net" dropdown list.

                                          You have to create a whitelist to override.
                                          If you run snort on the LAN interface then there is no reason to trust your hosts, no?

                                            Is this a bug or intentional feature / behavior that Snort doesn't download new rules after a uninstall / install (pfSense snapshot update)? I need to go and download the rules which will then start Snort when finished. Shouldn't this happen during the first start?

                                            I'm fairly sure it ran just fine after a snapshot update before the latest changes. Today I updated from 24th January snapshot to:
