I have two [VPS](http://en.wikipedia.org/wiki/Virtual_private_server) servers, and both have [MySQL](http://en.wikipedia.org/wiki/MySQL) installed, one for testing and one for development. One of my servers won't let me connect from outside. With the user;

According to [an open port finder](http://www.yougetsignal.com/tools/open-ports/), port 3306 for the offending server appears to be closed. I have C++ and Java programs of my own listening on arbitrary ports without any issues. Why is this happening and how can I fix it? 

Ubuntu installed is Ubuntu 11.10 (GNU/Linux 2.6.32-042stab072.10 x86\_64)
