[Snort-sigs] Manually download and install Snort Rules updates

How do I know where Pulledpork reads the tarball from?  Is it on the pulledpork.conf file or the pulledporl.pl script?  Also could I just copy over the snort.rules and so_rules.rules files from one device to another?

You can either download them directly from snort.org and scp them to the box or you can copy them from other sensors you have. In either case, you would place the rules tarball into the directory where PulledPork is configured to read the tarball from. For example, PulledPork is configured to read the tarball from /tmp; this is where you want to copy the tarball.

Once the tarball is copied as explained above, you will run PulledPork with some extra parameters, in addition to the ones you have already, to update the rules locally -nP

-n Do everything other than download of new files (disablesid, etc)
-P Process rules even if no new rules were downloaded

This will force PulledPork to process the tarball from the local disk instead of downloading the tarball from the internet.
