Remote connection and administration is very common and helpful.  OpenSSH or Secure Shell will allow you to get full terminal access at any terminal you are at, like bringing your computer with you.  I connect using Putty A Free Telnet/SSH Client. 

 You will need root access “administrative rights” to install.

Goto: your prompt and do these comands. “on your linux machine you want to connect to!”

sudo apt-get install openssh-client

sudo apt-get install openssh-server

-While connecting with putty you will come across these screens

While connecting you will just put in your username at your domain name or ip address

such as mark @ techtutorial.com without spaces. See picture.

 this is a warning that the key is not stored on the computer yet.  If you click yes it will prompt for a login.

Once authenticated you will be connected and look you have your terminal right in front of you with no messing with a spare mouse or keyboard and you dont have to try to walk someone though a command to start a service when it fails or needs to be restarted.
