The reason I'm mailing the -net list is because I seem to have tracked down something I'm just not sure where to look now. If I use ping I get 5% drops -- 872 packets transmitted, 827 packets received, 5% packet loss round-trip min/avg/max/stddev = 0.168/2.263/357.140/20.485 ms If I use hping (to the exact same ip with icmp as well) I get none -- 875 packets tramitted, 875 packets received, 0% packet loss round-trip min/avg/max = 0.2/2.5/357.2 ms Is there some buffer filling up? Where can I look to try get more information. Any help/suggestions would be muchly appreciated Thanks Dave
