You may ask "Why another version of the hostname command?". The answer is
|
|
simple. A lot of people misuse the domainname command to get the DNS domain
|
|
name. Since the domainname command should ONLY be used to set/show the NIS
|
|
domain name (formerly known as Yellow Pages) there was no easy way to get
|
|
the FQDN (Fully Qualified Domain Name) or the DNS domainname from within a
|
|
shell script.
|
|
|
|
This hostname command offers you some additional features:
|
|
|
|
- show the FQDN (long host name)
|
|
- show the short host name
|
|
- show the DNS domain name
|
|
- read the host name from file
|
|
|
|
For further informations simply type "hostname --help" or read the manual
|
|
page.
|
|
|
|
If the program is called as dnsdomainname it will simply show the DNS domain
|
|
name.
|
|
|
|
If you ONLY use the loopback mode you can only use the normal features
|
|
(set/show the host name) since you probably don't have a FQDN (Fully Qualified
|
|
Domain Name) in the /etc/hosts file. You can change this by either using
|
|
the dummy device or by changing the localhost line in /etc/hosts to
|
|
something like this (it will use localhost as an alias name):
|
|
|
|
127.0.0.1 erdos.maths.groucho.edu localhost erdos
