[Snort-users] Logging - A easy way ?

Change the icmp to UDP (or add another rule to do that).. do a UDP,
then the alert should fire.. then you know snort itself is seeing the
udp packets at that box.
and if you want to see if it works sniffing the netowkr, then udp scan
another box, whos traffic should pass through the span port, and then
see if it fires.
