How to use SSH in Linux ?

All modern Unix-like systems (Linux, OS X, BSDs, and others) include a command-line ssh client. To login to your computer from a Unix-like machine, go to a command-line and type:
ssh <username>@<computer name or IP address>
Example:
ssh This email address is being protected from spambots. You need JavaScript enabled to view it. (or) ssh This email address is being protected from spambots. You need JavaScript enabled to view it.
You should get the usual password prompt (or be told you can't log in, if passwords are disabled).See ssh keys if you want to authenticate using keys instead of passwords.
