The below is the correct description. --------------------------------------- If it receives a icmp packet that: 1. icmp total length is bigger than 28(8 header + 20 data) 2. icmp[0] == 3 (or 4, 11 , 12. other value?) 3. (icmp[9] & 0x05) < 5 -- (ip header length < 5?) 4. icmp[17] == 17 or 6(other value?) -- (protocol field in ip header?) then it reboots. ---------------------------------------
