Snort: Won't Update, bad checksum
-
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.
-
same problem… hopefully there will be a fix soon!

I described the problem alredy in another thread before i found this one:
https://forum.pfsense.org/index.php?topic=114954.msg638677#msg638677a 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.

Same here, working now!

Worked on 7/12/16 BUT hasn't updated since. I "Forced Update" and I get a
"Snort GPLv2 Community Rules md5 download failed.
Server returned error code 0."Any suggestions?

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 :)
-
Has this snort download issue been fixed? I was planning on buying into the snort rules tomorrow.

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.

Hello,
I'm also struggling to get rules updated after REinstalling pfSense-pkg-snort-3.2.9.1_14. I've tried adding and removing line 459 and "force update" per the solution given by Paint on 07/12/2016 with no success. I'm noticing the MD5 codes listed for both the downloaded and expected rules files.
Any suggestions about other things I can try?
Thanks!

The Rules update has finished. Time: 2017-01-04 15:48:34this 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.
-
Yeah, to be clear this is absolutely wrong place to post. Noone here maintains the snort.org webservers so noone here can fix broken checksums they keep uploading over and over and over again. If you have a paid subscription, complain to the Snort guys, if you have none, then you get what you paid for and simply wait till someone fixes it.
