Hi, I started an X Server with none of the parameters being "-ac" (i.e. Access Control is NOT defeated) and I am NOT using XDMCP. As expected, the X Server is only accepting X Clients from the local machine. How do I make the X Server accept X Clients from specific remote machines also ? I am supposing that I would need to give the X Server some form of an Access Control List, which I could do because I know which remote machines I want to use. Regards Alan J. Caruana
