Out of curiosity - does anyone know why Google is truncating ICMP responses ?
Assuming (not confirmed) mitigating old-style DOS attacks. See "ping
of death." ICMP packets should be small enough to never require
fragmentation. But large enough to contain at least the header of the
original packet.
When I used to write firewall stuff, there was a great debate about how
much data to return in an ICMP error/reply packet. I don't think the
debate was ever resolved.
