Requirements RedHat Linux (should apply to 7.x and up) This
tutorial covers changing your hostname in RedHat Linux without having
to do a reboot for the changes to take effect. I?ve tested this on
RedHat 7.3, 9, Fedora Core 9, and RHEL 5.3. It should work for all the
versions in between since they all closely follow the same RedHat
configuration. What?s the point of this tutorial? Never reboot if you
don?t have to and keep your uptime intact. Make sure you are logged in as root and move to /etc/sysconfig and open the network file in vi. cd /etc/sysconfig vi network Look
for the HOSTNAME line and replace it with the new hostname you want to
use. In this example I want to replace localhost with ?MyServer?. HOSTNAME=MyServer When you are done, save your changes and exit vi. Next we will edit the /etc/hosts file and set the new hostname. vi /etc/hosts In hosts, edit the line that has the old hostname and replace it with your new one. 10.33.44.55 MyServer Save
your changes and exit vi. The changes to /etc/hosts
and/etc/sysconfig/network are necessary to make your changes
persistent(in the event of an unscheduled reboot). Now we use the hostname program to change the hostname that is currently set. hostname MyServer And run it again without any parameters to see if the hostname changed. hostname Finally we will restart the network to apply the changes we made to /etc/hosts and /etc/sysconfig/network. service network restart To
verify the hostname has been fully changed, logout of your system and
you should see your new hostname being used at the login prompt and
after you?ve logged back in. Quick, painless, and you won?t lose your server?s uptime.
The Acer Aspire 4710 uses a SATA hard drive. Unfortunately Redhat Linux 9.0 does not have SATA support (uses the 2.4 kernel). You will have to upgrade to something recent like Fedore Core 7 or Ubuntu 7.10. Hope this helps.
