This is only some strange restriction that Netbeans adds. Xdebug doesn't
care. The idekey is only required and used for DBGp proxying.

localhost is fine if IDE and PHP/Xdebug run on the same machine.

I would suggest to have a look at the /tmp/xdebug.log contents, as it
might provide valuable clues.

> Hello. I'm trying to enable xdebug, and have run into a problem that I can't solve. xdebug seems to be configured and enabled, but fails to connect to a waiting debugger on the same host as the server (I tried geben in emacs and the xdebug supplied debugclient). I get a message from the debugger "Waiting for debug server to connect." and nothing happens. xdebug does output a stack trace in the error log.
