I noticed (among the more common icmp: echo request) these odd icmp types. The external net, my firewall is connected to, is plagued by smurf-attacks from various sources. So I have tcpdump watching.
Of what I gather, this icmp-type should not exist. Can anyone shed some light on this: ,---- | 11:49:16.273069 62.211.198.163 > x.y.z.255: icmp: type-#69 | 11:54:58.078683 62.211.198.163 > x.y.z.255: icmp: type-#69 | 11:56:29.741012 62.211.198.163 > x.y.z.255: icmp: type-#69 | 12:02:08.959131 62.211.198.163 > x.y.z.255: icmp: type-#69 | 12:08:28.202081 62.211.198.163 > x.y.z.255: icmp: type-#69 | 12:15:16.880586 62.211.198.163 > x.y.z.255: icmp: type-#69 | 12:20:58.878889 62.211.198.163 > x.y.z.255: icmp: type-#69 `---- Cheers, Cristian
