Are there many people using FreeBSD 6.x and Smokeping? I asked this a while back but nobody seemed to have any input. Ever since moving from FreeBSD 5.3 to 6.0 (currently 6.1) I have been seeing artificial loss in smokeping that does not exist. It always shows up as two repeated intervals of 19/20 packets received (light blue) and never at the same time on any of the monitors. I think there is some sort of ICMP rate limiting or something else going on in the kernel but I have never been able to locate it. Users on the FreeBSD-Stable list didn't have any input either. You can clearly see on all of my graphs at the precise time I upgraded from 5.3 to 6.0 there is slight loss from that time forward. It makes the graphs that are logged for long periods of time look bad (always light blue) instead of mostly green which they should be (for my network anyway). I've done numerous tests with other tools to verify there is no packet loss from the same machine. I cannot reproduce the statistics I see with Smokeping using anything else. I'm hoping someone might have some input (other than use Linux). :)
If you need any more information about my setup, just ask. Almost all probes are Fping based and there are somewhere between 50 and 60 monitors setup. The server is a Dell 2650 with dual P4 Xeon 2.8GHz CPU's. MP kernel is enabled. I was toying with disabling MP to see if it was some sort of weird problem with multiple CPU's. Any help or suggestions are appreciated! :) -- Vinny Abello Network Engineer Server Management [EMAIL PROTECTED] (973)300-9211 x 125 (973)940-6125 (Direct) PGP Key Fingerprint: 3BC5 9A48 FC78 03D3 82E0 E935 5325 FBCB 0100 977A Tellurian Networks - The Ultimate Internet Connection http://www.tellurian.com (888)TELLURIAN "Courage is resistance to fear, mastery of fear - not absence of fear" -- Mark Twain -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/smokeping-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
