I think that's generally a bad way to customize rules unless you're
careful. Moving a rule into local.rules usually means it will be
forgotten and stay there untouched forever, i.e. if the official
version of it gets updated, you would still have the old one.
Now some shameless plugs...
I would use the "modifysid" function in Oinkmaster
(http://oinkmaster.sf.net/) to customize the rules instead. This way you
can continue to use the latest and greatest rules automatically while
still being able to tweak them, like changing the priority.
I tried to document these things in the Oinkmaster FAQ (Q21).
By the way, if you really ment Snort 2.3.3, you should upgrade to
2.4.3 ASAP. See the warning at http://www.snort.org/dl/old/ if you
don't believe me.
