How to change hostname in raspberry pi
What is Hostname?
A hostname is the label assigned to a device on a network and is used to distinguish one device from another on a specific network or over the internet.If you are using ssh in your raspberry pi,then the concept of hostname will help you to make it little more easier.
Since IP address can change ,it is not a good idea to use IP address for ssh configuration . So here i would like to explain " how to change the hostname in raspberry pi"
1.Login into raspberry pi terminal
2.Use hostname command
This will show you the current host name of your pi(if you are using rasbian distribution from raspberrypi.org then the default hostname will be "raspberrypi.local" )
3.Use sudo hostname command
Then change the hostname in this file ( using " mypi " as new hostname)
4.Next use sudo nano /etc/hosts and change the hostname in that file
5.Next use sudo nano /etc/hostname and change the host name in this file
6.Lastly use the reboot command (or sudo reboot) to restart the raspberrypi ,
and ssh back in using this new hostname
sudo ssh <username>@hostname.local
