Moving a Linux machine is fairly simple, but it requires that the IP address on the machine be changed in several locations. This has been automated. Register a new IP address for a Linux machine then log onto the machine in question and run (as root):

/home/fjord/a/redhat/changeip <new address>

So, for example, if you wanted to give a machine a new IP of 128.46.154.76 you would run:

/home/fjord/a/redhat/changeip 128.46.154.76

Once changeip is run you can shut down the Linux machine (poweroff or shutdown now -h work nicely, but you should know this already) and physically move it. When the machine is next booted it will have the new address and correct routing info for the new subnet.

Similarly, there is a changename script. Run it (as root) with the desired new hostname (not fully qualified domain name, just the hostname):

/home/fjord/a/redhat/changename <new hostname>
