Chris, Thanks for pointing that out - I had forgotten about that bug report. The case I'm looking at is where an ICMP echo request goes out with an ICMP header of 8 bytes + a payload of 32 bytes for a ping. Then I receive an ICMP destination host unreachable containing the original IP header and ICMP header but *not* the 32 byte payload from the original ICMP echo request. My understanding is that this lack of echo request's payload (per RFC #792 - "Internet Header + 64 bits of Original Data Datagram") causes the ICMP echo request to no longer be verifiable. I have both the original and returned packets and the IP total length is 60 bytes in both cases, unlike in the bug report you had made. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
