Re: Restart snort inline without traffic loss?

If Snort is configured with reload option such as --enable-reload, then you can supply the -H argument to pulledpork 
whenever it is run. This will cause Snort to reload the new signatures processed by pulledpork without having to 
shutdown the Snort process. However, there are certain limits to what can be reloaded, such as dynamic libraries, 
output plugins, and other configurations from the snort.conf file.

Hi,

I am new to snort, I have it installed on a web server running inline
mode
with iptables, nfqueue, barnyard2 and snorby.

I've downloaded the emerging threats rules, firstly all the rules are
alerts, do I have to convert these to drop if I want to drop the
traffic?

Have a look at Pulledpork,  http://code.google.com/p/pulledpork/, it will
do this for you + a lot of other cool things.
Assuming I do, how do I restart snort without loosing good traffic,
currently if I kill the process and restart I lose about 30 seconds of
traffic while snort restarts, not good on an ecommerce site.

I also would like a fail safe nfqueue bypass in case things go wrong, at
the
moment if snort goes down I also get locked out but its on a cron job to
restart if its down for more than 1 minute.

I need some advice please..

Thanks.


Regards,
Lysemose
