Recently (last few weeks), networking on my server just stops working. I can't make any new connections (TCP or UDP) and there is no network traffic other than some arp & netbios stuff. `ifconfig' and `route' look normal and there's nothing in the system or kernel logs. I can restart the network with `service network restart', and everything is hunky-dory. It doesn't happen that often, perhaps once every few days, but the frequency seems to be increasing to about once a day. It stops usually at night. (During the day I frequently listen to Internet radio and I don't recall having to restart the network.) When the network is not working, I've poked around with netstat, ethereal, in addition to the two previously mentioned utilities. I haven't seen anything unusual. Ethereal reports some arp and netbios traffic (normal), but nothing else. It will not exit cleanly. There are also hung processes, I suspect because they have open NFS files. I've appended the list of rpms that I have installed. The only one I can imagine might affect networking is, of course, the new kernel that I installed about a month ago (kernel-smp-2.4.20-30.9 on Thu Feb 19 17:03:38 2004). `chkrootkit-0.43b' does not report any problems, and Tripwire hasn't shown anything unusual. I am behind a firewall (a D-Link DI624 wireless router) that only allows inbound ftp, httpd, dns, smtp, ssh, rtsp and cvs traffic. Any suggestions on how to debug this problem? Thanks. --- Vladimir ------------------------------------------------------------------------ Vladimir G.
