I disabled the firewall - which I do not think was running and same read out.
anarcho@LuNoHo:~$rpcnfo -p
Command ‘rpcnfo’ not found, did you mean:
command ‘rpcinfo’ from deb rpcbind (1.2.5-9)
Try: sudo apt install
anarcho@LuNoHo:~$
Ok, so that looks good. So strange that NMAP from OSMC doesn’t show the ports. Can try rpcinfo -p 192.168.0.10 from OSMC to see if that shows the ports (but I doubt).
I saw that as the Tunnel address on your Notebook.
What is that Tunnel about? What are you doing there!
A Tunnel IP should not be related to anything on the LAN!
AHhhhhh, you also have VPN activated on your OSMC!!!
That surely can mess up things. First disable all VPN’s so that we can reach a stable Network environment.
