One more thing I forgot, I am told...
Important: CHANGE YOUR PASSWORD AFTER INSTALLATION, using PuTTy (in Telnet protocol, port will be 23):
After installation of PurE2 image your login details are:
username = root (hit Enter button on your keyboard)
password = pure2 (> Enter, as above).
To change the password type: passwd (be careful!)
Now, enter the new password (5 - 8 characters long) of your choice and hit Enter button on your keyboard.
Repeat the password > hit Enter.
You will not see anything happen on the screen, when you are doing this, so BE CAREFUL!!! 
==========================RCU CAN DO, TOO!!!=========================
Alternatively, by simply using your Remote Control Unit, from the comfort of your armchair/sofa:
in PurE2 > MENU > Setup > System > Network > Password setup > input new password...
