ubuntu 8.10 静态 ip 问题

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:

Quote:

sudo update-rc.d –f NetworkManager remove

This will disable and remove the Gnome Network Manager application. Now you will have to edit your configuration manually.

RESTART SYSTEM

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.

Step 2.1 – Manually configure your network interface file: You can edit the appropriate file by entering the following command into the terminal:

Quote:

sudo nano /etc/network/interfaces

Once your prefered editor opens the file you want to enter the following information (changing your addresses where necessary):

Quote:

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)

Be sure to save your changes.

Step 2.2 – Manually configure your dns configuration file: You can edit the appropriate file by entering the following command into the terminal:

Quote:

sudo nano /etc/resolv.conf

Once your prefered editor opens the file you want to enter the following information (changing your addresses where necessary):

Quote:

# Generated by NetworkManager nameserver xxx.xxx.xxx.xxx(enter your dns server ip) nameserver xxx.xxx.xxx.xxx(enter your alt dns server ip)

Be sure to save your changes.

Step 2.3 – Manually restart your network interface with the new settings: Enter the following command in the terminal:

Quote:

sudo /etc/init.d/networking restart

This should return a result that looks like the following:

Quote:

*Reconfiguring network interfaces… [OK]

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.

Haven't tried reinstalling the Network Manger after doing these steps to see if it still works.
