Secure Shell or SSH is a network protocol thats allows users to communicate through network devices securely. SSH is ideally used to login to a remote machine and excecute commands but, it can also be used for Tunneling,forwarding TCP ports and X11 connections. It can also transfer files using SCP or SFTP protocols.

• Make sure that the package openssh-server is installed in the system.
   
• If not then go to system->administration->synaptic package manager and install the package openssh-server
  
  
• After the installation is complete, goto Terminal and type the command as follows

                                       ssh username@ip

• Here username refers to the username of the remote user's system and then its ip.
