Sorry, my customer is bound to SL 6.10, a medical programm is only supported

Ubuntu 20.04 is an LTS version, in long-term support until ...
mainstream April 2023, extended security maintenance April 2030.
I would see when the medical program will be supported on Ubuntu 22.04
(the next Ubuntu LTS version, due out next spring) and move to Ubuntu
20.04 or 22.04.
, a new server was just installed 2 months ago
for 25 linux workstations (XDMCP linux clients, Win10 with NX ). Thats the
server for next 5-7 years!! No update possible, special features for
userfriendly communication with medical server in internet only supported
under 6.10. , NOT 7.x , 8.X!!
Once again: who has idea why nxserver 3.2.0-74 is locked/ blocked?
I see you are using
xhost +
Even in SL6 that was considered very insecure.
Could you/they switch to xauth security instead ?
If you are using heavy graphics and need GPU, DRI or OpenGL you may be
stuck with NX, but otherwise I would consider switching to using VNC
for the display connection.
Oh, I see that NX supports VNC clients; I would try that, perhaps in
windowed mode if that suits your use, rather than having the whole
desktop sesson on the medical server.

Hello,

Stop there. Update to SL 7 if you expect contemporary tools to work or
continue to work: the underlying RHEL 6 from upstream The final
release of RHEL 6 was more than 3 years ago.

Why not accessible viel IP/ network? Only accessible local? What is locked

/home/pc44/.nx/C-arthur-1002-27736AF6397123CD7F3F645BCA8E28A4/options
-nolisten tcp :1002
nxstarts with "-nolisten tcp". Where is that set? - In
/etc/nxserver/node.conf:
#AGENT_EXTRA_OPTIONS_X="-nolisten tcp" # is commented out!!
When I modify it to
AGENT_EXTRA_OPTIONS_X="-listen tcp" # nolisten -> listen!
Then nxserver doesn't allow any login, aborts with error message
Error: Aborting session with 'Unrecognized option: -listen'.
anybody here can help?
Some security policy on SL 6.10 that forces nxserver to "-nolisten tcp" ?
Or: who or what forces to start nx with "-nolisten tcp" although its not
commented in in node.conf?
