Hi,

Oinkmaster can modify the rules on the fly just after downloading.
You have to configure him as explained in the example. It is based on Sids, so 
you just can tell to oinkmaster to comment out your rule given a sid.

Objet : Re: [Snort-users] ignore bad rule on startup

Thank you for your answer Paul
however i'm asking if there is an option, an argument, a switch or
something, to make snort skip eventual garbage during startup

i've seen snort refusing to start due a 'fwsam' directive in some
bleedingedge rules, like the file 'bleeding-dshield-BLOCK.rules'

or, for example, if it finds two rules with the same SID

i'll like to know if the behaviour could be to simply skip those rules

this would provide me to auto-download the rules,
maybe with oinkmaster

now it's not possible because if a new rules update could breaks snort,
it will not startup anymore

think about the disaster if snort is inline:
all the traffic would be waiting in queue !

thank you very much for your time
.mike

Hi all !
i've just subscribed this list and here comes the first question:
is there a way to make snort ignore a bad rule on startup, instead of
throwing an error and don't start at all ?

Sure.  Just comment the rule out.
