How to change hostname in Linux

I’m trying to build an Oracle RAC system at work to understand how it works better. As part of this I had to build three Linux systems. I built one, then cloned it (it was a virtual machine in VMware).

But having done that, it of course kept the hostname of the first machine. So I had to work out how to change that.
It turns out that is quite easy.

  • Edit file /etc/sysconfig/network using your favourite editor. In my case is nano.
  • Look for HOSTNAME=xxxxxx
  • Change the xxxx to the name you wish to set for your computer.
  • Save the file and restart the xinetd service. (eg. type service xinetd restart in your shell)
    Or simply reboot.

What’s all the fuss about Ubuntu ?

I see that Ubuntu has released a new version of its desktop edition. It seems to be a very popular distribution although I haven’t used it myself much, but I might give this new version a try for a while.

I’ve used Red Hat a little and I was running a Debian server at home for a while. I know its not linux at all, but I kind of prefer Solaris 10. It’s what I use at work and what I’m most used to (aside from Windows). Although I will grant you, some things are easier to do in Linux. But Solaris feels like a real operating system.

Juscelino over at J.M.A daily has an interesting post about the 5 reasons linux will never be better than windows. I agree with most of what he says. Although many things about using and installing Linux has become easier over the years, Microsoft has spent and will continue to spend millions and probably billions of dollars developing software that is easy to use for as many people as possible.
