OK.

Dont forget you can also use
          rdesktop
to windows ( if you like that sort of thing )

yup

You shouldn't be getting to here.


Set
        ENABLE_EXTERNAL_NXVIEWER="1"
in
        /etc/nxserver/node.conf



<boring explanation>

This code section is obsolete
and
nxviewer which was ( or would have been) a custom vncviewer
(included as much for compatibility with nomachine as for anything)
        **  doesnt exist **
but
hasn't been removed because no one has set the default
        ENABLE_EXTERNAL_NXVIEWER=
in
        nxloadconfig
as above ( even I haven't, but I don't use it (much) )

you have been caught out by "missing documentation" syndrome

Luckily I can function like a dynamic .pdf, having had to work it all out
myself . . .

Yup.

You can vnc to anywhere from the server, but if you want the NX server you 
can 
        1/ shadow an NX session
        2/ X connect to the console

You can also vnc from a normal NX desktop or as an application

Never existed AFAICT (DBTCMIIW)

No. Did it work ??

It's easier to ask me than plough through all that shell script

Well it was prbably a good idea at the time ( 2008 )
