Permissions.

Question 1: Update demo account

If you have just completed all the previous tutorials you need not use this setup button. However, if you have skipped part or all of the previous tutorial questions, or when you ran your virtual machine the demo account was missing, then the button below will create the demo account and create the files which the previous tutorials would have had you create.

By pressing the button below a new account is created called "demo", password is also "demo". Log in using this account and you cannot do any damage. If you mess the account up and want to start again, just press the button again.

Once created, you can log into this account using telnet or ssh, logging into the hostname linuxzoo.net. Remember the username is demo and the password is demo. And remember, you cannot break anything using this account! The account begins with an empty directory, so dont be shocked that "ls" shows nothing...
