Software :: Vim Not Connecting With Xdebug For Php Debugging

I'm running Ubuntu server 9.10 karmic koala and my client is also ubuntu 9.10 karmic. I've installed xdebug on the server and added to the php.ini file:

zend_extension = /full/path/to/xdebug.so
xdebug.remote_enable = 1
xdebug.remote_port = 9000
xdebug.remote_host = localhost
xdebug.remote_handler = dbgp

Vim and the proper plugins (debugger.vim and debugger.py) are both installed. I load the php file under consideration in my browser on the client with ?XDEBUG_SESSION_START=1 as part of the URL. I then vim the php file, press F5 and reload the page in firefox. Vim shows that it is waiting for 5 seconds for the connection. After 5 seconds it shows an error message that says:

[Code]....

After some googling it has become apparent that these messages mean nothing and the problem is that the connection is just never happening. Xdebug is supposed to be working on port 9000. I've looked at /etc/services and nothing else is mapped to port 9000. I've tried ssh -p 9000 xxx@a.b.c.d and had the connection refused (ssh without a port spec works fine). Now I don't know what to do to get this thing working and I really want it working.
