Hi, I found that executing
solved some problems, like, pinging localhost works and MonoDevelop will start, but - where to put that command so it gets executed at boot time?

Thanks

You have severe probs there, the loopback device (lo) should always be up on boot otherwise lots of things stop working! Sorry I can't be of more help but I'm not familiar with ubuntu's boot model.

Hey, you met some point! You're an analyzer, aren't you?

On boot, there are always error messages like, "Basic networking -- failed".
After I've logged in graphically, I always enable eth2 (which is my current network card, and which is usually disabled in the graphic dialog after booting), and next, setup pppoeconf to dial-in to the DSL provider.

Actually, pppoeconf should access the internet at boot-time, automatically. On both Ubuntu 5.10 and 6.06 (both betas) (on different computers) I had to re-configure and initiate the internet connection everytime after I was graphically logged in.

Where do I have the option to adjust the settings manually?

Thanks indeed
