When you have established contact with the Unix system, the login prompt will be displayed. You must give your username followed by your password:
Password: secret1 -the password is not in fact displayed when you type it
The username can be up to 8 characters in length. Unix usernames contain only lowercase characters, and it is important that you type your username in lower case (if you don't you will be permitted to log in, and then the shell will not recognise case differences.) The password must normally contain between 6 and 8 characters. On some unix systems the password must contain at least 1 non-alphabetic character.
