Windows VNC client cannot access due to no security types supported

Post by ssxitoperations » 2019/06/06 14:35:16

I enabled VNC through screen sharing in Gnome. I think this runs the vino as the VNC server.

From a Windows computer, I used various VNC clients (e.g. TightVNC, RealVNC, etc.).

All of them return an error message indicating no security types supported.

Did some research and it seems that vino requires TLS encryption. The workaround is to bypass encryption by disabling it

Code: Select all

gsettings set org.gnome.Vino require-encryption false
I tried that and restarted machine. However, I still get the same error.

Any ideas on how to get VNC working?

Just install the tigervnc server package and configure it properly.
I prefer to tunnel VNC traffic through ssh.

For details check the documentation

I followed the instructions in the article.

I was able to configure the VNC server for a single user and can remote into it fine by remoting with [IP of machine}:[display number]

However, I wanted to setup VNC based on xinetd with XDMCP for GDM also referenced in the article. I completed the steps required. However, when I tried to remote in with [IP of machine]:5950 -- I received a message that the machine actively refused it.

It looks like xinetd never loaded the new services. Am I missing a step?
