]

In the line enter

kdesu kwrite

or use your favorite text editor. When you are finished press enter. After a few moments, you should than be greeted with a password dialog box.

In this box enter your root users password, when you are done press OK.

Your text editor should now open. In our example "kwrite" will open.

Click on the "OPEN" button and open the following file.

/etc/sysconfig/network

We are only interested in on line in this file. This is the first line starting with

HOSTNAME=localhost.localdomain

Now we want to change it to reflect our new hostname. In this example we want to change it to read.

HOSTNAME=workbox.localhost.localdomain

When you have finished click on "SAVE" Once saved you can than close your editor. Your changes will now take effect the next time you reboot your computer.

Also Note: I've found that I need to add DHCP_HOSTNAME=<myhostname> to /etc/sysconfig/network for my router to "see" the hostname.

Changing Your Hostname yet another way

Open synaptic and install the package edit_hostname

Once installed you can run the file from your menu -> Configuration -> Change Hostname

when ran a dialog box will ope as below. Simply put your desired host name in the box labeled Enter Hostname. When finished click on save. The dialog box will close.

Another way to run the program is from a terminal window. Open a terminal window as root and typed edit_hostname.sh at the prompt followed by pressing enter. A dialog box will open. Enter your chosen hostname in the box labeled Enter Hostname and then click Save. The dialog box will close. You can simple close the console window.

As with both options, your new host name will appear after you restart your machine.
