Manual workaround for setting static IP address bug in Ubuntu 8.10 Intrepid Ibex
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:
This will disable and remove the Gnome Network Manager application. Now you will have to edit your configuration manually.sudo update-rc.d –f NetworkManager remove
Step 2 – Manual configuration of your network interface: In this step you will manually configure your network interface by editing the following two files using your preferred text editor(nano gedit vi). For the purpose of this example I am using the nano editor.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:
Once your prefered editor opens the file you want to enter the following information (changing your addresses where necessary):sudo nano /etc/network/interfaces
Be sure to save your changes.auto lo eth0
iface lo inet loopback
iface eth0 inet static
address xxx.xxx.xxx.xxx(enter your ip here)
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:
Once your prefered editor opens the file you want to enter the following information (changing your addresses where necessary):sudo nano /etc/resolv.conf
Be sure to save your changes.# 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:
This should return a result that looks like the following:sudo /etc/init.d/networking restart
At this point in your terminal you should be able to run the ifconfig command and the results should reflect your new settings. If the addressing is correct you should have full network access, even after a system restart.*Reconfiguring network interfaces… [OK]
Haven't tried reinstalling the Network Manger after doing these steps to see if it still works.
