localhost localdomain

[cigtoxdoc]

i forgot my password and had to go into root by using recovery mode on boot and reset my password. Now instead of my pc being called a600n it calls itself localhost.localdomain. How do i fix this?

OS= 12.04 32-bit

john

What is the output of:

cat /etc/hostname

[cigtoxdoc]

john@localhost:~$ cat /etc/hostname
localhost.localdomain

Hello ,
you can change the names is two files .

1st , the file that @ducan12 mentioned

2nd , the file /etc/hosts.

Be careful to write the SAME name exactly.

e.g :

I want to change the name of computer to MyComputer.

I do

gksudo gedit /etc/hostname

and write

MyComputer

Then I do

gksudo gedit /etc/hosts

and change the 2nd line next to 127.0.1.1 (the first line is localhost) with MyComputer .
So the contents of the file /etc/hosts will be

127.0.0.1    localhost
127.0.1.1    MyComputer

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Reboot for the changes take effect.

Thanks
