Setting Up Your Host Name and DNS Addresses
To set up the host name of the Linux machine and the addresses of your Domain
Name System servers, select the Host name and name server button. A screen like
that shown in Figure 1-24 appears.
The host name of your Linux machine can be anything you like, such as a person’s
name, a descriptive name, or something random. The only thing that you have to
bear in mind is that the host name and domain name can contain only letters and
numbers as well a hyphen or an underscore. The host name can be only one string
of characters and cannot contain a space or a period. As the name suggests, the
domain name dictates the network domain that this machine falls into. This domain
may well be something in line with your company’s policy or could be something
you have set up yourself.
When integrating a new system into an existing networked environment, you should
always follow the same naming conventions that are already being used, especially
for the domain name. If you do not, other systems on the network may not be able
to locate your system correctly, and certain services on your system may not be able
to interoperate with existing network services.
