[FreeNX-kNX] No nx service

[Jim]

FC8 x86_64
Error message ;
"The NX service is not available or NX access was disabled on host 
76.251.280.60"

The rpm's I have installed on x86_64 is;
nx-2.1.0-22.fc7 x86_64.rpm
freenx-0.7.1-3.fc8 x86_64.rpm

 From the Fedora repo's

I get the error from my Laptop i386 box, with the Nomachine  
nxclient-3.1.0-2.i386.rpm installed , trying to connect to my x86_64 box.
I can successfully connect to another i386 PC box with fedora in another 
state, using NXclient from this same laptop.
