      Hello all-

      I just upgraded my pfsense firewall (from a snap on Tuesday May 31 to a snap today 2.0-RC2 (amd64) built on Tue Jun 7 06:12:50 EDT 2011).

      After I update SNORT with my oinkcode, add the interface and categories etc. it will not start.  If I try and start it via command line this is the error I get: '/libexec/ld-elf.so.1: Shared object "libpcap.so.1" not found, required by "snort"'.

      I unchecked all the categories I had selected and tried to restart the SNORT service, didn't make a difference.

      Any ideas on how to fix this?

      Thanks,

        Plus 1 here.. same issue.

        I did a clean install of the latest snapshot.. thrice… Same issue.

        Something has definitely gone wrong with the Snort package.

          I am not having problems with snort at all.  I know one important thing must be done right after an upgrade of pfsense.  You must manually update your rules in the snort>updates tab before trying to start since there's no sync after install.  When it re installs the package, the snort rules get deleted.

            Yes sir.  Before I make any changes the first thing I do is update the rules, then do the config.  Guess I will just have to keep messing with it.  Strange thing is, I've always done the same thing after upgrading to the latest snap, this is the first time it broke for me.

                I recently deployed 6 PFS 2.0RC2 boxes. The first two were deployed a week or so ago and I installed snort via the package manager; the other ones were installed a few days after. I have noticed on the more recently built servers I am having the same issue with snort failing to start.

                As others have noticed, it appears to be an issue with the dynamic link to libpcap. The WORKING snort I had installed was exactly the same version (2.8.6.1 pkg v. 1.34) as the "broken" snort installs, except the difference is the working snort installation has the following:

                $ ldd /usr/local/bin/snort
                /usr/local/bin/snort:
                libpcre.so.0 => /usr/local/lib/libpcre.so.0 (0x8006f9000)
                libpcap.so.7 => /lib/libpcap.so.7 (0x800835000)
                libm.so.5 => /lib/libm.so.5 (0x800966000)
                libc.so.7 => /lib/libc.so.7 (0x800a85000)

                The non working version has the following:

                $ ldd /usr/local/bin/snort
                /usr/local/bin/snort:
                libpcre.so.0 => /usr/local/lib/libpcre.so.0 (0x8006f4000)
                libpcap.so.1 => not found (0x0)
                libm.so.5 => /lib/libm.so.5 (0x800830000)
                libc.so.7 => /lib/libc.so.7 (0x80094f000)

                My resolution was this:

                ln -s /lib/libpcap.so.7 /lib/libpcap.so.1

                the result is:

                $ ldd /usr/local/bin/snort
                /usr/local/bin/snort:
                libpcre.so.0 => /usr/local/lib/libpcre.so.0 (0x8006f4000)
                libpcap.so.1 => /lib/libpcap.so.1 (0x800830000)
                libm.so.5 => /lib/libm.so.5 (0x800961000)
                libc.so.7 => /lib/libc.so.7 (0x800a80000)

                I won't say that this is an "official" fix but it does appear to work without issues and allow snort to function until this is resolved…
                Hope this helps someone!

                  Ok, so I tried the above fix.  Didn't work for me. Here's what it says:

                    At the bottom of this website, they talk about the same issues: http://michaelok.tumblr.com/

                    I'll read through it and possibly try some fixes and post back :)

                      Hello all–

                      I have same error after upgrade to 7-june and 8-june pfsense2-RC2 amd64 full.

                      after I ln -s /lib/libpcap.so.7 to /usr/local/lib/libpcap.so.1
                      and try running snort on the web-configurator I got unsupported output plugin: "alert_pf" error on my syslog...

                      @th3r3isnospoon:
                      ERROR: parser.c(5165) Could not stat dynamic module path "/usr/local/lib/snort_dynamicpreprocessor/": No such file or directory.
                      is dynamic lib path error.. the path in pfsense is "/usr/local/lib/snort/dynamicpreprocessor/"

                        FWIW, I submitted a bug report.

                          Hi all,

                          I have the exact same console output.  The interesting thing is syslog.

                          In the latest release of pfsense 2.0-RC2 I can't get Snort to start.  The syslog reveals the following:

                          Jun 9 07:12:19 SnortStartup[63658]: Snort HARD Reload For 34679_sis0…

                          Line 207 of the above file is:

                          output alert_pf: /usr/local/etc/snort/whitelist/defaultwlist,snort2c

                            no go.

                            Are we the only ones facing this issue? Can anyone else confirm the same with a clean install of pfsense and snort package?

                              Mine had some clean installs and I did have the issue; which I resolved with my ln fix. I'm not sure why it's not working for others. :(

                                Latest few snapshots even dynamic DNS is failing and IP shows in red as 0.0.0.0

                                Looks like both a snapshot and Snort package issue.

                                  I looked into snort.inc, looks like snort supposed to fetch perl-threaded-5.12.1_1.tbz as dependency… but couldn't find anywhere... the link to the file seems broken... I don't know if this is the cause of alert_pf error... hope this will be fixed soon. :)

                                      It's possible the maintainer is on vacation.  I sent him a pm a while back and have not yet received a response.

                                            Over a week since the package is in broken state  >:(

                                            Has no one installed snort since last 7 days?
