ssh tunnel + rdesktop + virtualbox windows

1. We'd like to create an ssh tunnel between home pc and office PC.  On home pc,  type the following command

> ssh -L 3389:localhost:3389 timwu@deansoft

This means all traffic toward localhost:3399 will be redirected to timwu@deansoft:3399

2. on office PC, execute the virtualbox instance winxp
> VBoxHeadless -s winxp

3. then you can run rdesktop to attach remote windows screen
> rdesktop -P -z -a 8 localhost

-z -P -a 8 is for low bandwidth
