The Pi sets up RealVNC. Is it possible to use a TightVNC client to connect to it?
I have enabled the VNC server on
Raspbian GNU/Linux 10 (buster) without any special configuration. From the Pi to localhost the
vncviewer localhost works fine.
When trying to connect from a Debian host I get a security type error. This is on Debian Stretch
apt install xtightvncviewer:
$ vncviewer pi.local
Connected to RFB server, using protocol version 3.3
No configured security type is supported by 3.3 VNC Viewer
It looks like the Pi is running RealVNC and I'm trying to run TightVNC on the client. Seems like it should work.
RealVNC is not in the main Debian Stretch repository. I'm trying to work with something that is. Other options
ssvnc (tightVNC with SSL/SSH support) are available but do not work out of the box.
