Hi! I have a really weird problem with some of my servers, namely all the ones running Centos5 When I try to download a file from the server to a machine outside our Cisco 6500 router/firewall, the download hangs about half the times (15 out of 40) when less than half a megabyte into the transfer (varied from 76 kb to 496 kb). One server has a portchannel (Cisco speak for ethernet bundle), others do not, some use e1000, some use broadcom, I've tried httpd and scp transfers, I've tried from three different clients, Here's the really annoying part: the problem only occurs when downloading from outside the firewall, not when transferring files internally in the serverroom! And the switch is the firewall is a modular chassis, so the data comes over the same backplane regardless. And there's 42 files in /proc/net/sys/ipv4 which differ between EL4 and Centos5, so I'm a little lost here Anybody got some ideas? with kind regards, Bent PS Crossposted from Centos Forum, in case sombody on the list, who doesn't read the forum, can help me _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
