Debian testing no network on boot
I am running Debian testing and after a recent dist-upgrade networking no longer comes up automatically after booting. eth0 doesn't come up and more surprisingly neither does the loopback interface. I can configure these manually after booting but would obviously like to have the interfaces come up during boot process. During the upgrade a new networking program 'dnet' appears to have been installed which I suspect is related to this problem. During the install it wanted to be configured so it could change the mac address of my nic. Until it was configured eth0 was dead and wouldn't come up at all. Does anyone know what's wrong and how I can fix it? I'm tempted to uninstall dnet but it's obviously been installed for a reason. I've googled around and haven't been able to find anything that helps with a fix. Many thanks in advance Geoff

Any messages in the logs about firmware? That wouldn't explain the loopback interface though. I don't know what dnet is (unless you are running DECnet :)... whatever it is, maybe you could do dpkg-reconfigure on it to get it to ask you the configuration questions again in case you made a typo?

dnet-common is a DECnet package, do you know why that would have been dragged in on my last dist-upgrade. I did a dependency check and the only package that it depends on libroar2. DECnet doesn't look particularly useful? Anyways I checked /var/log/dpkg.log to see exactly what the last dist-upgrade did and found that ifupdown had been removed!! Re-installed that and networking starts on boot again. Cheers Geoff

Why not apt-get remove the package and see if that makes a difference? Also try "ifconfig -a", as just "ifconfig" by itself won't show downed interfaces.

It appears dnet wasn't the problem. An inspection of /var/log/dpkg.log revealed that apt in it's wisdom uninstalled ifupdown on my last dist-upgrade. I've re-installed and all is good again. Cheers Geoff

You're running testing. You're expected to keep an eye out for such things, and to deal with problems as they arise. If that's too hard, debian stable is <over there>. PS: I couldn't find a polite way to say the above. Sorry about that.

I always read the list of packages that will be removed *before* I confirm the dist-upgrade. I've learned that lesson before.

That a very fair call. I've been running testing for many years now and know the drill so don't have an excuse for not paying more attention.
