I'm trying to set up a development box using Virtualbox / Vagrant / Puppet with the intention of eventually provisioning all my machines up to production. However this is stopping me going forward at the moment. I've installed ubuntu lucid over windows 7. When trying to connect to xdebug by starting a debugging session in eclipse, it hangs at 57% (common in eclipse when it cannot communicate with xdebug). Here is my xdebug.ini and the settings here are appearing in phpinfo(). xdebug.remote_enable=On xdebug.remote_handler=dbgp xdebug.remote_host=192.168.56.1 xdebug.remote_port=9000 I'm now wondering if it's an issue with port forwarding? If eclipse is looking on port 9000, will it find port 9000 on a virtual machine? Any help would be greatly appreciated!
