host name

[nanjil]

when I open a shell tjhe prompt in my system is

<name>@localhost

this despite the fact teh machine has been asiigned a definite name by the dhcp server.
why does my machine does not recognize its own name?

The dhcp server assigns you an ip address, it has nothing to do with the hostname.
To change the your hostname do

nano -w /etc/hostname

Change it to whatever you like.
Hit Ctrl + x to quit, say y to save your work, hit Enter.
Hostname changed.
