      2.2-RC (amd64)
      built on Sat Jan 10 03:54:06 CST 2015
      FreeBSD 10.1-RELEASE-p3

      When I reboot the system (Diagnostics, Reboot, Yes), I see this message
      Stopping /usr/local/etc/rc.d/snort.sh…done.

      but snort is not installed, no packages are installed.

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

          It looks like snort does not remove that snort.sh on deinstall: https://github.com/pfsense/pfsense-packages/pull/784

            Yeah, it was a bug leftover from some earlier experimenting when I was trying (unsuccessfully) to get each configured Snort interface to show up as a separate service under the SERVICES menu.  Looks like that piece of experimental code got sucked into the production branch due to an error on my part.

            Phil has submitted a Pull Request to fix the problem (thanks …  :)).  And as Cino noted, you can just manually delete the file and the message will go away.

              Ok, so the problem was/is easily rectified and doesnt hopefully amount to much, but one question I do wonder, is what sort of oversight is there for code getting pulled?

                Just noticed as I've just installed snort (15:22 local time), firstly it wasnt showing in the packages, but having installed it, the below text is visable on the snort updates page.

                Would this also be connected to the snort.sh script?

                Edit.

                Just to be clear, this was a fresh memstick install this morning, restored a backup but later decided to abort it so I chose to use the option 4 on the console, reset to factory defaults.

                Is it possible the Reset to factory defaults is not resetting everything ie there are still traces of apps & settings from packages left over?

                I could not see anything in the xml backup related to snort apart from "snort_alerts-" found in the <widgets><sequence>section having done the factory reset.

                fwiw.

                  The devs with commit access look at it before committing it - Renato seems to have been doing most of that lately, and I know he makes quite a few comments on people's pull requests.
                  I scan stuff for obvious dumb typos… but when it is a big pull request I don't think through every line of logic in detail. And there have been a few others who have caught and given code review comments also.
                  Obviously the more competent people who review this stuff, the less errors get through - so feel free to browse pull requests and commits regularly and comment on them.
                  But from a configuration/security point of view, I think the devs are doing good review now. There won't be any back-doors or other "bonus code" introduced by contributors - that will be caught before commit.

                    Would this also be connected to the snort.sh script?

                    No, this is simply showing that upon the reinstall, Snort detected an existing configuration in the config.xml file and acted upon those settings.  Snort's settings are stored in the _<installed_packages></installed_packages>_section.

                    I have not tested this, but it very well could be that the reset to factory defaults only resets the pfSense firewall settings and leaves any existing packages information in the aforementioned _<installed_packges></installed_packges>_section of config.xml alone.

                    Thanks for reporting these inconsistencies.  I will look into them and fix them as necessary.  There have been at least three different sets of "hands" modifying the Snort package over the years, and there is some inconsistency here and there in all the PHP code.  For example, in some cases Boolean parameters in the config are stored as "yes" or "no", while in other places it may be "on" or "off".  I have been trying to clean those up.
