Re: Pulledpork and sid-msg.map

[Jeremy Hoel <jthoel () gmail com>]

Ok, I would still do it manually before you run pulledpork in the no
download mode.  That way you can still get all the features of pp without
changing it at all.

So basically you could run pp normally then cd to the directory where the
rules are (normally /tmp), run the sed command and then run pp again with
the -n switch.

try that and see if that give you the output you want.
