Assuming the Network Security Toolkit was booted with a network card and the network card drivers loaded properly, you will have access to the Network Security Toolkit system via ssh (or putty - for Windows users). Assuming the Network Security Toolkit has a IP address of 192.168.0.17, you should be able to connect in the following manner (NOTE: Just hit the enter key at the passphrase prompt, and then enter your password at the password prompt):

[pkb@salsa docs]$ ssh root@192.168.0.17
Enter passphrase for key '/home/pkb/.ssh/id_rsa':
root@192.168.0.17's password: nst@2003 # NOT ECHOED

Please note, ssh access is only available if the sshd is running on the Network Security Toolkit. This should always be the case if you used the default boot settings.
