There are times you may want to control a computer remotely.
One of the best and most secure ways of doing this is with
                  ssh (Secure Shell)

ssh allows you to connect to another computer with encryption.
Once connected, you anything you do through the connection
is actually being done on the other computer.

The way you connect using ssh is to run the ssh command
and provide the username and the ip address of the remote machine.

ssh <user>@<ip address>

* note, if the remote user is the same as the local user 
* you don't need to enter a name
* and domain names can be used in place of the ip address if available.
* ssh mysite

Let's connect to a remote machine.
We will connect to a small camera running Linux.
We will connect as root (admin)
* note, normally you don't want to login as root
* but some times small devices only have root users 

 ssh root@192.168.1.30

I this case the password will be ember
Once logged in try running some of the following commands 

# make the camera talk
  tell "Hello"
  tell "I hope you are doing well" 

# move the camera to preset positions
  ptz_presets 0
  ptz_presets 1 

# control the camera using keys WASD 
  ptz-ctrl 

# play an audio file 
  audioplay /mnt/mmcblk0p1/mario.wav 70 
 


# when done you can disconnect with exit
  exit
