I've been running Squeeze for awhile, and like most Debian "testing" systems, it has been running fairly smoothly.
However, today I ran into a problem with OpenVZ, the kernel, udev, and sysv-rc.
Seems that some combination of an update or some other, my network interfaces would not start. I believe that this was caused primarily by an update to udev without and update to the kernel, or to sysv-rc.
I'm running apt-get upgrade now, and I'm very hopeful that one of the updates will fix the problem. I'm very glad I had KVMOIP setup, as the server was simply offline, and its about 8 hours away. :-(
Once I was able to access the console, the usual command did nothing:
Instead, I issued the following commands:
ifconfig eth0 192.168.8.12 netmask 255.255.255.0 up route add default gw 192.168.8.1 eth0 ifconfig lo 127.0.0.1
Good, back online.
So if networking restart does not work, what does? A little research turns up this:
invoke-rc.d networking restart
Nope, still no luck on why no networking in starting on this machine. It has other problems, so I can't diagnose at the moment.
The server at least needs a new CMOS battery (CR2302), and after that, I plan to do a complete re-install of Debian Squeeze, including a change from RAID5 to RAID10.
