I bought The Linux Cookbook by Michael Stutz.

dsl.org/cookbook

Anyways, it says to change the computer name type the command /etc/hostname
I'm running RH9 and it says theres no such file.

So how the heck do i change my computer name from Localhost.Localdomain to ..........UNDERWORLD!?

it should be there

/etc/hosts

oh yea that file was there. do i just delete the word localhost and replace it with what i want?

Mine looks like this

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 UNDERWORLD localhost.localdomain localhost

Oh, cool, thanks man.

had to change both these files for rh 7.3 - my computer name is Tron

/etc/sysconfig/network

/etc/hosts

To check if it is correctly set, use the /bin/hostame command. It should return the hostname. If not, use it to set your hostname : #hostname ServerName

You should tell Michael Stutz that by default their are no executable files in the /etc directory. It mostly deals with configuration files. Must be a typo.

I love you guys.....

ive had the same problem, and using the GUI to fix it (there is a tool for it) broke apache.

I did what megaspaz said, and it fixed everything (althought i had to reboot, im assuming restarting the network and logging out and back in would have worked too)


I will add a comment since chances are its your first time using linux, use emacss to edit the files

emaces /etc/sysconfig/network

emaces /etc/hosts

to save the changes to the files, typ:e control+x control+c y enter.


(assuming you are messing with this for the first time, you may have needed that, if not, sorry for insulting you)
