[FreeNX-kNX] Protocol mismatch or no authentication data

[Peter O'Gorman]

Hi,
We managed to finally connect to a 2.1.0 server using a 2.1.0 client  
by patching nxnode.

There is a condition if [ "$clientproto" = "1.5.0 ] that then sets  
ookie=$proxie_cookie, if we remove the condition and unconditionally  
set cookie then I can connect.

We found that xauth was being called and add was failing because  
$cookie was unset.

Thanks,
Peter
