Hai,
If you feel like getting started with Linux, you can use this:
http://linuxzoo.netIt's pretty cool and useful.
OS available:
- Fedora 15
- Caine Forensics
- Win 2008/7
You can access it using something like putty or the available Java gui...
If you're into forensic Analysis, the Caine CLI & Autopsy are nice and well known.
I'm not quite sure how restricted are the guest accounts, but it's worth a try.
