Easy way to get into root is just to download the X Terminal shell and type sudo su - and you are straight into root. Beware you can do a lot of damage which is why I have always thought sudo su - is a the second most dangerous Unix command after rm -f /*

It is therefore worth setting up a password for the user 'user' or someone may hack into it from a wireless connection!

You should be able to issue any command from a shell as if you are logged in directly. You should also be able to sftp or scp into it the same way to copy files up and down.

Hmm - that's interesting. I added a passwd to user and need that to ssh in from outside the box but not if I open the XTerminal or, more importantly. if I sudo su - into root. Not standard at all and rather dangerous.

do I really have to tell you how dangerous it is when unwanted person has physical access to linux device?

Just my two cents, i have modded mine quite heavily, and nearly all the mods do come with good guidance on each post - the problem is they are spread out quite far!

All of the themes available for download are quite heavily modded in the visual sense though - worth looking through those as a start!
