I think this is what I originally needed to do, although I must admit I currently don't see these changes in my x0.hosts file so not sure if it is now no longer needed or I modified my setup in some other way to avoid the requirement.

However if you are having the same problems with both xming and SSH from a separate nix machine then the issue is likely not this.
