If you need to xdebug a remote php application, which is behind a firewall, and you have an ssh daemon running on that machine. you can redirect port 9000 on that machine over to your local machine from which you run your xdebug client (I am using phpStorm) So, run this command on your local machine and start your local xdebug client, to start debugging. more info: http://code.google.com/p/spectator/wiki/Installing

Will not handle filenames containing a single-quote (but if you are moving those, it's time to go yell at whoever created them in the first place).
