Secure Shell or SSH is a network protocol used to remotely access the Linux shell (that is something similar to the MS/DOS prompt of the Windows users) to launch programs or do anything else on the FOX Board.

To remotely access the FOX command line (shell) from a Windows PC it is available for free a very light application called putty.exe and freely downloadable from:

• http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Putty.exe doesn't need to be installed, just download and run it.

At startup you have to specify:

• Host name: is the FOX Board G20 IP address. Read this article to find it
• Connection type: SSH

Save this configuration and press the Open button to continue.

As shown on the image above, do specify the FOX IP address, select the SSH connection type and click on Open button.

FOX Board will show its prompt and the request for login:

Type root and then netusg20 at password request.

The debian GNU/Linux welcome message and debarm:~# command line prompt will appear.

The FOX is now ready to execute your commands:

Try to type:

debarm:~# pwd 
/root

to know were you are in the FOX filesystem then move to the root (/) and get a list of files and folders:

debarm:~# cd /
debarm:~# ls 
debarm:/# ls
bin   dev  home  lost+found  mnt  proc	 root  selinux	stage2	tmp  var
boot  etc  lib	 media	     opt  sbin  srv	sys	usr

On a Linux Ubuntu GNU desktop open a new terminal session selecting the the menu Applications → Accessories → Terminal then type:

$ ssh root@192.168.1.28

Where 192.168.1.28 has to be replaced with the IP address of your FOX (Discovering the IP address).

At first login a security message will appear. Confirm it typing yes

The authenticity of host '192.168.1.28 (192.168.1.28)' can't be established.
RSA key fingerprint is cc:8b:6a:3d:05:d2:34:34:2b:65:17:57:50:00:17:e6.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.1.28' (RSA) to the list of known hosts.

At password request type netusg20:

root@192.168.1.28's password: netusg20
