I have three scripts which have been working for quite some time but now they don't (within the last two weeks).  They are located at the following addresses:
http://www.jbnf.net/reachability.php
http://www.jbnf.net/rcon.php
http://www.jbnf.net/status.php

Has something changed server-side that would disable the f.... commands or has something been firewalled?  Nothing has changed in the code but none of them work anymore.
