Login problems
Are you having problems logging in? Here are some tips.
Use your username
When you login to a DICE Linux computer, use your DICE username.
That username is the same as your University Username ("UUN" for short). For students it's the letter "s" followed by your matriculation number.
For example, if your username is s2345678 then type this to login: s2345678
Do not type: UUN
Do not type: [s2345678]
What's a firewall?
A firewall is like a doorman who keeps unwanted people out of a building.
Imagine that you are at home, using your laptop, and you want to use a computing service that's at the University. When your laptop tries to contact the University computer, its network traffic has to cross the internet, then go through the University's firewall computers.
The job of these firewall computers is to allow through only legitimate, harmless-looking traffic. Unwanted network traffic is not passed through, so it never arrives at the University computers.
