Worth Trying Remote Computer Connection

This article explores remote computer access techniques, such as using x11vnc and pikvm for graphical interfaces, ControlMaster for persistent SSH connections, and port forwarding for secure access. Additionally, it suggests utilizing high-quality KVM switches with audio redirection and separate USB ports as hardware solutions to enhance the overall experience.

x11vnc can proxy existing x11 desktop on web.

sudo apt install x11vnc

for hardware kvm over ip, there is pikvm swite for turning rpi3b+ into ipkvm and armkvm series that are dedicated low cost ipkvm hardwares.

to persist ssh connection:

ssh -o ControlMaster=auto -o ControlPersist=yes -o BatchMode=yes user@hostname

ssh port forwarding:

# requires sudo
sudo ssh -v -N -L <local_addr>:<remote_addr> -R <remote_addr>:<local_addr> <user>@<remote_host>

remote or local address must at least have port number specified, optionally with host address like: [host]:<port>

-L opens a local port at local address and forward to remote address. -R opens a remote port at remote address and forward to local address. -N disable the tty connection. -v shows the debug info.

enable pubkey authentication for nomachine:

first generate the key with ssh-keygen, copy your pubkey content at .ssh/id_rsa.pub (local host) to remote host at ~/.nx/config/authorized.crt, one pubkey per line.

next change the setting AcceptedAuthenticationMethods as NX-private-key in file /usr/NX/etc/server.cfg at remote host.

no need to restart the service. change your connection method to key based authentication and select the private key file path.
