Eu escrevo uma regra fácil para testar dinâmica / atividade. Mas eu recebo
WARNING: an activation rule with no dynamic rules matched.
12/26-03:35:45.759678 [**] [1:100:0] Activating [**] [Priority: 0] {ICMP} 192.168.1.1 -> 192.168.1.2
WARNING: No dynamic libraries found in directory /usr/local/lib/snort_dynamicrules.

dynamic icmp any any -> any any (msg:"Dynamic not activated"; sid:10000004; rev:011; activated_by:1; count: 10;)
O que devo fazer para que funcione corretamente?
