To permanently change your hostname that will survive the reboot, you will have to edit the file /etc/sysconfig/network. the command: $ hostname lappy is just a temporary change.

The actual file to change your hostname is: [arnav@dhcppc1 ~]$ vi /etc/sysconfig/network If you edited file /etc/sysconfig/network, then you need to reboot your computer.
