note 30991 added to function.gethostbyaddr

Hello, alrighty, here's my setup at home: |---Windows laptops (2) Internet ---- DSL Modem (static IP) ---- Gateway ---- Linux box the problem i'm having is that reverse DNS is not working on the linux box, specifically, the PHP function gethostbyaddr simply returns the IP address, not the hostname. my /etc/resolv.conf file contains the DNS servers for my ISP. see http://www.yankeesinthesouth.org/test.php (and http://www.yankeesinthesouth.org/test.phps for source). are there any other network options that need to be set to get reverse DNS functioning? the box can browse the web, etc just fine without any problems. thanks, dm -- http://www.php.net/manual/en/function.gethostbyaddr.php http://master.php.net/manage/user-notes.php?action=edit+30991 http://master.php.net/manage/user-notes.php?action=delete+30991 http://master.php.net/manage/user-notes.php?action=reject+30991
