Hello again, Also, if I use tethereal to sniff for icmp packets to the host I'm pinging I see them all even though I am getting drops -- 23 packets transmitted, 22 packets received, 4% packet loss The last two lines of my tethereal -- 45 22.214610 x.x.x.x -> y.y.y.y ICMP Echo (ping) request 46 22.215133 y.y.y.y -> x.x.x.x ICMP Echo (ping) reply 46/2 (request/reply) = 23. So 23 packets actually went out and returned, yet I still get drops? Thanks again Dave -----Original Message----- From: Dave Raven [mailto:dave@raven.za.net] Sent: Tuesday, February 26, 2008 6:21 PM To: 'freebsd-net@freebsd.org' Subject: Hping/Ping Hi all, I have a problem where my machine is dropping packets and pings after a few days of running (under load). 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
