Free Shell Accounts

I would like to ssh tunnel ALL of my internet traffic because I use my laptop all around my university campus, I know that this is not that safe. I have looked everywhere and found nothing, basically does anyone have heard sites like these were they offer free shell accounts? I know that I could use my home PC but the PC belongs to the family but they routinely turn it on and off, this would simply not work.

Thanks

You might find something here:

If it doesn’t have to be free, you should be able to get something for about $25 (USD)/year.
