What is SSH?How to install SSH?



SSH:

        1.Secure Socket Shell.

        2.SSH is program and protocol for securely logging into remote machines  across a network. It allows you to run programs, and do a variety of tasks as if you were sitting at the machine.

Example:
                  If a person is accessing computer A,and at the same time,you want to access the files which are present on computer A,then at that situation you can use SSH from your terminal as follows.

               ssh -X Computer_A_IP_ADDRESS

As both can access the files on one machine without affecting each others work.

Installation:
                       
sudo apt-get install openssh-server

Enter password of computer_A

Enter yes

then from your computer try to access your computer_A using

ssh Computer_A_IP_Address.
