Hi, I'm stress testing some network devices by doing some cross flood pings among them. It occurs sometimes that one of the hosts (host foo) will stop answering to pings from other hosts. foo can ping all the other hosts, and I can use ssh back and forth, but it doesn't answer ping requests. More info: - tcpdump at foo actually shows the ping requests (but no replies) - other network interfaces connected at foo also stop answering pings - icmp_echo_ignore_all is 0 - foo cannot even ping itself. I would swear it was able to ping itself, but just went to confirm it for this mail and found out it isn't. I took a look at icmp.c to see where the packet could get dropped but found nothing. I assume it's some kind of DOS prevention, but I don't know where it is taking place nor how to revert it. Any clue would be appreciated.
