I'm running an X server on a virtual host (VSD controlled) and just had this message from the sysadmins:

"It's come to our attention that the X server that you're running on xxxx.com is listening on IN_ADDR_ANY rather than the
specific IP address that has been assigned to your Virtual Server.

This is causing problems for some of our other customers, so I'd like to ask that you reconfigure your server to only listen on IP address xxx.yyy.zzz.www. I'd appreciate confirmation when this has been done. "

I just start Xvfb on startup, its effectively a headless workstation. How can I do what they want? Is there a general setting to tell processes to listen to spectific IP addresses or is there something in the X server I should look at please?
