Although VNC allows multiple users to view the same screen at the same time (and fight over the mouse if they wish).

In all seriousness though it's useful if you use VNC just to remote monitor a screen and want to leave it open indefinitely.

Also RDP uses TCP and UDP which makes it bad for SSH tunnelling, as opposed to VNC which is TCP only and easy to tunnel.



RDP can be limited to TCP. Microsoft's client autodetects whether UDP is available and can work without it.


I'm not an expert on RDP. But I tunnel RDP over SSH all the time... What am I doing right?


it's very common to use RDP over an SSH tunnel. it's not great in low bandwidth situations, of course. but in today's world, it's usually fine.


It works much better in low bandwidth situations if UDP is also available because then things like "the user just closed this application, stop downloading this picture" can happen.

With TCP multi-megabyte buffers can end up forming and when you've shoved data into TCP there's no way to cancel sending it.
