After an upgrade of my desktop machine to Ubuntu 8.10 Beta the NetworkManager in GNOME makes a mess of my network settings (Say truely, which “manager” doesn’t make a mess out of the thing he/she needs to… manage :p).
Anyway… my setup is very simple. One ethernet connection with a static IP. Can’t be hard, don’t you think? Well, NetworkManager manages to redefine an “Auto eth0″ (DHCP enabled) connection every time it restart and just ignores the nice “Static eth0″ I’ve added.
The config of “Static eth0″ is not in /etc/network/interface, but added through the NetworkManager. You would think that does the trick, but it ain’t.
Also, when I delete “Auto eth0″ and I set the “System setting” flag on “Static eth0″, the flag is reseted as soon as I open the “Static eth0″ details again.
There is a bug filed at Launchpad.
And another.
And another.
Gotta take some time to start trying the proposed solutions in this threads… I’ll report back to you!
