Network-Manager applet missing if / eth0

It seems that network manager is not configured to manage interfaces which ifup/ifdown is configured to maintain

gksu gedit /etc/NetworkManager/nm-system-settings.conf

or

gksu gedit /etc/NetworkManager/NetworkManager.conf (appears to have changed to this since squeeze has gone live)


Change
[ifupdown]
managed=false

To
[ifupdown]
managed=true

# restart networking
/etc/init.d/network-manager restart
