The WIERDEST problem!!!!!

[SHSaeed]

Hi,

The last couple of days I've run into the wierdest problem.. On one of our servers, we have about 32 IPs added. At times, I've noticed that about half of these IPs get really slow (high ping times) and have high packet loss while on the other half the ping is very fast and almost no packet loss. The IPs are randomly good/bad, not in any specific order or anything.

Anyone have any idea what the problem might be and maybe a solution?

It seems that there was a network upgrade at NAC

So you don't think it might be the NIC causing the problem? Traceroutes show that the problem start at the server.

Connect to these servers and traceroute and ping to your IPs
then you will have the results that you can count on
(you can't count on results which you get from a dial-up, dsl, or other non-route servers)

telnet://route-server.ip.att.net/

telnet://route-server.east.attcanada.com/

telnet://route-server.west.attcanada.com/


(I've selected Regional in-source and out-source Routers due to NAC)

Thanks a lot, I will make sure to use these next time (if there will be a next time) the ping goes up a little.
