Changing Hosts file on Debian6
how to change hosts in debian6

http://www.cyberciti.biz/faq/debian-change-hostname-permanently/

Save and close the file. You may also need to edit the /etc/hosts file, enter:
# vi /etc/hosts
Find all references to server1 and replace with server2:

127.0.0.1 localhost
127.0.1.1 server2
# 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

Save and close the file. Please note that the host name is usually set once at system startup in /etc/init.d/hostname.sh (normally by reading the contents of a file which contains the host name, e.g. /etc/hostname). Just type the following command to apply new changes without rebooting the server:
# /etc/init.d/hostname.sh start
