Nomachine "NX> 596 ERROR: Could not generate cookie: ."


Distribution: OpenWrt, custom

I am using Nomachine NX for headless control, shadowing existing desktop.

Success scenario:

After boot, if, manually as root on server machine do:

"startx &", then SUCCESS, can remotely control server desktop

if, however, I place in rc.local for unattended X startup

"startx &" OR "su root -c startx &" then, FAIL with:

Nomachine "NX> 596 ERROR: Could not generate cookie: ."

this is bizarre, because rc.local is run as root, but, I suspect that something in the environment is different between the two startx invocations.

anyone "have a clue", which I am lacking?

Solved: NX> 596 ERROR: Could not generate cookie: .

Sorted this out. Works, but testing not complete.

If you get the "NX> 596 ERROR: Could not generate cookie: ." error,
the first thing to try is

"rm -f /home/nxuser/.Xauthority"

This was insufficient for me, so I had to:

1 - Completely uninstall NoMachine NX on server
2 - rm -rf /usr/NX
3 - remove user nx and any nxuser and their home directories defined

add nxuser
re-install NX on server

in rc.local:

rm -f /home/nxuser/.Xauthority
su root -c startx &

where nxuser is the client user YOU have defined.
