I have an old page on it--probably completely outdated. It's one of those things where the docs on their site are about 4 years old and useless.
But I don't know if that page is any use anymore either, to be honest. I only run it on CentOS, but the Fedora install, at the time I used it, was completely lacking documentation, and in addition, needed some tricks to get it working.
On the other hand, last time I tried the nomachines one, it wasn't working properly for me either, but at that point, a friend was making a CentOS package, wanted it tested, I did, and it worked, so the nomachines issue was quite possibly something simple I overlooked, then never went back to checking.
