I would recommend you to use -i $MONITORINTERFACENAME-$COUNTER instead, because if you monitor 4 interface on the same system then you could Still encounter $COUNTER collision. -elzOn Tue, Sep 4, 2012 at 5:24 PM, beenph <beenph () gmail com> wrote:On Tue, Sep 4, 2012 at 5:09 PM, Jack <kingofnerds () gmail com> wrote:In case anyone is interested, I modified a start script I found on a forum somewhere to start multiple instances of snort and barnyard2.
