Q. Under Windows Server 2003 I can use active directory domain tools to get information about current domain and hostname. Can you tell me command to list current domain name and hostname under Red hat enterprise Linux 5?
A. Both Linux / UNIX comes with the following utilities to display hostname / domain name:
a) hostname - show or set the system’s host name
b) domainname - show or set the system’s NIS/YP domain name
c) dnsdomainname - show the system’s DNS domain name
d) nisdomainname - show or set system’s NIS/YP domain name
e) ypdomainname - show or set the system’s NIS/YP domain name
For example, hostname is the program that is used to either set or display the current host, domain or node name of the system. These names are used by many of the networking programs to identify the machine.
$ hostname
Output
sun521nixcraft.com
The domain name is also used by NIS/YP or Internet DNS:
$ dnsdomainname
Output:
nixcraft.com

Hi
Had a good read through your site. The featured articles is an excellent section. Learned loads of things I did not know about the Linux OS I didn’t know.
Good luck.
