Hi Jason,

Have you looked at the -P option?

I’m testing PP 0.7.0 and seeing what looks like a bug but want to confirm
it’s not a config issue on my end.



As I tune the sensor I add entries in each of the config files
(enablesid,disablesid,modifysid conf files) and then run pulledpork and
restart snort



/usr/local/bin/pulledpork.pl -c /usr/local/etc/snort/pulledpork.conf –vv



If there are no rule updates to download (from either VRT or ET) I get this
output

Next if I go into disablesid.conf and add another entry and re-run pp I get
the same output as the first run – the new entry in disablesid.conf doesn’t
get parsed or disabled in the snort.rules file.



Any ideas?
