That's exactly what "pulledpork" does.. it first checks the latest MD5 from VRT and compares against the last rules tarball that it fetched.. if matches.. the it does not re-download the file.. that being said, I am about to check in the code that will handle changes in the md5 file format.

I think this just MD5 sum's the file after download? How about something built into Snort for auto rule updating that would check a page like http://dl.snort.org/sub-rules/snortrules-snapshot-CURRENT_s.tar.gz.md5 against the last downloaded MD5. If it doesn't match, go ahead and download the rules then and only then. This should reduce the bandwidth load of people just constantly grabbing the 90mb rules file over and over. Tenable does something similiar with their NASL feed system. -- Eoin Miller Joel Esler wrote:On Fri, May 29, 2009 at 12:56 PM, Jeff Dell <jdell () activeworx com <mailto:jdell () activeworx com>> wrote: The problem with once a week is what happens if you check on Monday at 8am and the rules are updated on Monday at 8:05? You won’t get any updates for 2 weeks. It would be really great to have something like a checksum that will be available to see if there is a change in the rules file. This way users know exactly when an update has occurred and even if they check it every 15 minutes they will be checking a tiny file as compared to 90megs+ file. Then incorporating this into your favorite update utility will make updates very fast most of the time as there won’t be an update to the file, and would severely lower the bandwidth that snort.org <http://snort.org> needs. A tool was recently written by one of our guys here at Sourcefire called "PulledPork". http://code.google.com/p/pulledpork/ This tool updates rules and does exactly that (Checks the checksum of the rules first). -- joel esler | Sourcefire | gtalk: jesler () sourcefire com <mailto:jesler () sourcefire com> | 302-223-5974 ------------------------------------------------------------------------------------------------------------------------------------------------------Register Now for Creativity and Technology (CaT), June 3rd, NYC.
