I guess that’s a limitation of the tap/tun interface. I tried searching there are workarounds, but not really a good way.

Thank you for the information. I believe it will make it more convenient to share access to services between Clients and NX Server, and possibly between servers.
(Sound seems like Kubernetes 😀 )

Strangely, these devices still appear in dmesg logs, but don’t work.

Thanks, I forgot it could just do that. 😀

I configured it on a proof of concept machine and copied all of its config to all the remaining machines. Perhaps there was an error somewhere when configuring manually.

I think for crontab is quite simple, I will check every 30 minutes, and if any host has problems, it will automatically call ssh with the command “/etc/NX/nxserver –restart” to restart the nxserver on that host.

But it’s the immediate solution…. I will find out the reason why it is forced to restart (or it will hang and cannot be accessed).
