Using NX protocol, and there is no $HOME/.nx/config/client.crt.  Only player.cfg is there.  All directories are owned by my user.

I don’t have any $HOME/.nx/R-*, only  F-M* and M-* directories.  The latest session says:

I agree it shouldn’t change.  I’ve only installed NX once on all my machines, yet every day it complains that the key has changed.  Same details, in fact I’ve created icons with the IP, port and other settings, which has never changed.

Here’s how I use it, in case it makes a difference.  I run nxserver on the remote CentOS 7 machine. (installed with rpm)  The server starts with systemd.  In the config file I’ve changed each port it listens to, to reflect the IP of that host, for example 192.168.1.14 listens to port 4014.  On the client machine, I set up a reverse SSH tunnel, which reaches out to the remote machine, takes 127.0.0.1:4014, and brings it back to the client through the tunnel, so 4014 then shows up on the client at 127.0.0.1.  On the client when I hit the icon, it goes to 127.0.0.1:4014 and the machine reaches into its bellybutton and gets 4014 from the remote machine as if the remote server is local.

I’ve used reverse SSH tunnels for many years, to extend all kinds of services, and I can’t see why it would have an effect on the NX keys, but I thought I’d explain my method.  Also my method is the reason I wish there were a way to make nxserver listen only on 127.0.0.1, as I don’t want anything listening on outside interfaces for security reasons (in case the firewall is ever compromised).

Thank you, that works.

Another question:  Every morning when I start sessions on the various remote machines, it always says the remote host key has changed, and I have to approve the new key.  This should not happen, and could mask cases where the key has actually changed maliciously.  Why is this happening?

I don’t have a Documents directory.  I do have ~/.nx/config/Hex.xns which I drag from file manager to the desktop itself (KDE), but it never appears on the desktop.  I try clicking on Hex.nxs in the file manager, but nothing happens.

Normally what I do is Edit the Start menu and create a new object there.  I have to give the command which is run to start that object, but no commands work that I’ve tried so far.

What is the actual mechanism of how this is supposed to start?  Isn’t an executable supposed to be associated with .nxs files?

Thanks, but nothing works.
