My snort alert file has only these entries so far. ----------------------------------------------------------- [**] ICMP Destination Unreachable (Undefined Code!) [**] 05/17-06:51:34.581889 Z.Z.Z.77 -> X.X.X.36 ICMP TTL:253 TOS:0x0 ID:0 IpLen:20 DgmLen:56 Type:3 Code:1 DESTINATION UNREACHABLE: HOST UNREACHABLE ** ORIGINAL DATAGRAM DUMP: X.X.X.36:63586 -> D.D.D.213:53 UDP TTL:125 TOS:0x0 ID:29521 IpLen:20 DgmLen:64 Len: 44 ** END OF DUMP [**] ICMP Destination Unreachable (Undefined Code!) [**] 05/17-06:51:38.578669 C.C.C.157 -> X.X.X.36 ICMP TTL:253 TOS:0x0 ID:0 IpLen:20 DgmLen:56 Type:3 Code:1 DESTINATION UNREACHABLE: HOST UNREACHABLE ** ORIGINAL DATAGRAM DUMP: X.X.X.36:63587 -> D.D.D.214:53 UDP TTL:125 TOS:0x0 ID:32081 IpLen:20 DgmLen:57 Len: 37 ** END OF DUMP ----------------------------------------------------------- The original datagram says it is a DNS query. I get notified via ICMP that the destination is unreachable. This looks normal to me. How do I find out which rule has triggered this alert. I am not going to remove that alert but will modify my DNS resolution. Is there a way to make snort dump the rule ID along with the alert dump? Any info appreciated.
