Ubuntu – How to change the computer name

hostname

When I connect to my server (ubuntu server 10.10), I get this:

name@server-name.belkin ~>

How can I remove ".belkin"?

You need to edit the computer name in two files:

/etc/hostname

and

/etc/hosts

These will both need administrative access, so run

gksu gedit /path/to/file

Replace any instances of the existing computer name with your new one. When complete run

sudo service hostname start

The name will also be changed if you restart your computer.

You should add :

Your Network Ip address          Name you want

Example :

192.168.0.1      My_Pc

127.0.0.1 & 127.0.1.1 are loop-back Ip addresses .

To know your Ip address just type ifconfig in Terminal .

if you are doing this in organization where you want to access this url anywhere in private network then configure DNS.

if you just doing in local system and want to access from a specific hosts then you can do this by /etc/hosts file

open /etc/hosts file using

sudo gedit /etc/hosts

then do entries like

192.168.100.2  domain.dev  hostname

also mention ip and FQDN on all system's /etc/hosts where you want to access . so , all system know each other.
