There seems to be a known bug with the Gnome Network Manager included with the Ubuntu 8.10 release that resets any static ip address settings that are set manually when the system is rebooted reverting back to a DHCP setup. These steps will remove the Gnome Network Manager and help you manually setup the required files for your static network configuration.
Step 1 – Remove the Gnome Network Manager: You need to complete this step first because if left installed this application will overwrite any changes you make to your configuration when the system is rebooted. This is apparently where the bug is located.
To remove the Gnome Network Manager issue the following command in the terminal:
sudo update-rc.d –f NetworkManager remove |
RESTART SYSTEM |
Step 2.1 – Manually configure your network interface file: You can edit the appropriate file by entering the following command into the terminal:
sudo nano /etc/network/interfaces |
auto lo eth0 iface lo inet loopback iface eth0 inet static address xxx.xxx.xxx.xxx(enter your ip here) netmask xxx.xxx.xxx.xxx gateway xxx.xxx.xxx.xxx(enter gateway ip here) |
Step 2.2 – Manually configure your dns configuration file: You can edit the appropriate file by entering the following command into the terminal:
sudo nano /etc/resolv.conf |
# Generated by NetworkManager nameserver xxx.xxx.xxx.xxx(enter your dns server ip) nameserver xxx.xxx.xxx.xxx(enter your alt dns server ip) |
Step 2.3 – Manually restart your network interface with the new settings: Enter the following command in the terminal:
sudo /etc/init.d/networking restart |
*Reconfiguring network interfaces… [OK] |
Haven't tried reinstalling the Network Manger after doing these steps to see if it still works.
