      2.3.1-RELEASE-p5

      I had the same problem tonight.  At first I had a bad checksum.  I restored to a known backup where I knew Snort was downloading VRT rules.

      NOW, Snort is giving me a "Server returned error code 422" error.  I had this error a couple nights ago but noticed that Snort had a new version come out.  I was using Snort Ver. 3.2.9.1_13.  After I upgraded Snort to 3.2.9.1_14 the "Server returned error code 422" went away for the past 2 days….

      BUT the "Server returned error code 422" has come back to haunt me tonight.  My thinking is Snort is having issues with 2.3.1_5???

      Have you tried reinstalling Snort or reverting to a saved backup image?

          There must have been changes on Snort side.

          I can download ET rules, Community rules, but not the VRT subscribed ones. I guess we have to wait.

              I described the problem alredy in another thread before i found this one:
              https://forum.pfsense.org/index.php?topic=114954.msg638677#msg638677

              a manual verify of the file shows a correct checksum, but a problem with the line format?!

                I think there is an issue with the MD5 checksum file posted along with the VRT rules.  That file is not formatted correctly (or at least is not formatted like it has been).  I suspect the Snort guys will get it fixed soon.

                Snort on pfSense downloads both the gzip rules archive and the posted MD5 checksum file from the VRT site.  It then calculates its own local MD5 checksum of the downloaded gzip archive and compares it to the value stored in the downloaded MD5 file.  If they don't match, it assumes the download failed and aborts updating the VRT rule set.

                You can see in the log snippets some folks posted that the "expected MD5 value" is showing up as blank.  That is not correct and indicates a problem in the downloaded MD5 checksum file's content.

                  if you want to temporarily ignore the MD5 issue for VRT rules, do the following:

                  Open the /usr/local/pkg/snort/snort_check_for_rule_updates.php in your favorite editor, go to line 459, and add $snortdownload == 'on';

                      457
                      458 /* Untar Snort rules file to tmp and install the rules */
                      459 $snortdownload == 'on';
                      460 if ($snortdownload == 'on') {
                  

                  Then go to the Snort -> Update tab and click Force Update

                  I recommend removing line 459 once this is completed.

                    @bmeeks and Paint,

                    Thank you for the info.

                    It's working now.

                    Snort is the only package I use in pfSense and I use on both interfaces ( strict mode).

                    It's perfect.. I love it.

                            Thank You for the quick response!  I got it working.  In the last 2 days I've installed squid.

                            I reverted back to a early restore point when I didn't install squid in the last 2 days and snort updates correctly.

                            I am guessing squid is somehow blocking snort updates, and pfsense packages.

                              I figured I'd update this with what turned out to be the actual problem.

                              It was not SQUID it was PFBLOCKER and a BOGON list I had installed from iBlocklist.com….

                              PFBLOCKER Bogon list was blocking the SNORT VRT Rules and other updates.  Kind of weird as this hasn't happened before and I've been using these lists for quite sometime...

                              ohh well...  at least I figured it out :)

                                  Yes, it has been fixed since the day it was reported.  The problem was a corrupted MD5 checksum file stored on the Snort VRT rules web site.

                                      this looks to be an error on the snort side of things - the md5 for the packages (from Snort) don't match the md5 listed for the download. This happens from time to time and will get resolved at Snort's convenience.

                                        Hi -

                                        I continue to get this "Bad MD5 Checksum" error on a daily basis.  I'm currently updated to the latest version of pfSense Base system - 2.3.2_1.  I believe that I've configured the Snort service properly (oinkmaster code.

                                        If you have any suggestions of what else I could look at, please let me know.

                                          People, which part of "this is NOT a pfSense issue" is difficult to get?

                                            To be clear, I didn't say this was a pfSense issue. – I've seen the previous responses to my request,

                                            What I'm asking is if there's a different avenue of investigation I might be able to pursue to figure out what the problem might be.  Perhaps with snort.org?

                                            You may have noticed from my badge that I'm a newbie here.  I was given the impression that this was a helpful forum.  My misunderstanding.
