i connect to a remote machine called 123.456.789.12 and would like to
display as machine1 instead of the long IP. After reading hostname usage and
testing for many times I still fail to do that despite I'm a root. is that
due to DNS restriction or some other commands I should use? Thanks for your
advice~

It's unclear to me exactly what you want to do. Here are several
suggestions:

- The name service itself is configured using /etc/nsswitch.conf.
You _must_ tell the system which service you want to use -- local
files (/etc/hosts), DNS, or otherwise.

- You can put static host name to IP address mappings in /etc/hosts.
See hosts(4) for details.

- DNS is configured using /etc/resolv.conf. If you don't have the
correct addresses in there, it won't work.

- Many networks use DHCP to configure local networking applications,
such as name services. If you set up your system to run DHCP, and
if you have a properly configured DHCP server, all of this will
"just work."

Dear Mr. James Carlson,

Thank you for helping me shape my question more precisely. In fact I am
using SSH to connect a machine with fixed IP, say, 133.144.155.66,
133.144.155.67, 133.144.155.68, ...

when I'm opening more windows, I can only see 133.144 something. I would
like to assign each machine a specific name so I can quickly identify which
window I should use. Thanks again.
