Gaargh! Upgraded Ubuntu and simply upgraded my existing problem. For some reason which I cannot fathom, my desktop with it’s nice wired connection is not permitted to connect automatically. With the wonderful new GUI based tools I can’t simply tweak the boot scripts to fix it.
This is definitely more painful then needed, but this works (with thanks to the people over at the Ubuntu forum):
1) Setup /etc/network/interfaces to have an appropriate entry for the
interface you use such as:
1: auto eth0
2: iface eth0 inet dhcp
You may also wonder why that entry is not already there… I know I did!
2) Purge the Network manager:
1: sudo aptitude purge network-manager network-manager-gnome
3) KILL the remaining Network Manager processes (if you don’t; any DHCP sessions you try and create will not bind)
1: root 5749 1 0 11:59 ? 00:00:00 /usr/sbin/nm-system-settings
2: --config /etc/NetworkManager/nm-system-settings.conf
3: xxxxx 6328 6086 0 11:59 ? 00:00:01 nm-applet --sm-disable
4) Restart the networking:
1: sudo /etc/init.d/network restart
The Pros of this approach ? There is now hopefully only one thing managing your network and it will no longer do it by creating merged config files in /run to do it. The Cons ? You lose your nice status icon. You may get over that.
