I'm running Xubuntu Hardy 8.04 (Kernel 2.6.24-19-generic).
The machine has been running fine on the current hardware with no real changes for years. Recently I've been using this machine for a lot of downloads, and a central point for copying files around. I've got a number of USB hard drives mounted locally, as well as a SAMBA share for my RAID array on another computer.
I've found when I'm running a lot of downloads, or file transfers, sometimes the networking will just stop working. I can ping locally, but not to the gateway, or out to the internet. To fix it I have to restart the networking:
Any torrents have to be restarted as they've gone to [CLOSED] in rtorrent, but hellanzb seems to recover on its own, once it can resolve the host address again.
sudo /etc/init.d/networking restart
dmesg just shows this for the eth0 restart:
[388006.122108] eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
[388016.901461] eth0: no IPv6 routers present
I checked in /var/log/messages, and I can't see any errors for the networking, just a lot for the hard drives and RAID connections. No problems with the USB drives, I assume the RAID connections are for when the networking goes down.
I was hoping to get some ideas on how to increase logging for the network connection to troubleshoot, or get some ideas on how to fix this problem. I do a lot of work on this machine remotely, so when it cuts out like this, it's a real pain.
