Veyon Community Forum

@studentloans999 Did you change the access group of the public key file to "Guest" or "Everyone" after importing? BTW the authentication test will only work on the master computer since it tests whether a private key file is readable and matches the public key file, so it's not an error if it "fails" on the client computers.

Have you installed all available Windows updates? The AcceptSecurityContext call has been an issue with certain updates 1 or 2 years ago. As a workaround you can enable the Use alternative user authentication mechanism option in the Windows configuration page in Veyon Configurator after enabling the advanced settings (View -> Advanced).

Have you verified that the key pair IDs are identical on all computers? Did you set the access group for public and private key files properly? The public key file needs to be readable by everyone/guest on all computers while the private key file should be accessible by Veyon Master users on the teacher computers.

Hi,
There is a way, besides of Veyon which could meet easily your need, and give you ideas : BGinfo.
https://docs.microsoft.com/en-us/sysinternals/downloads/bginfo

This is a small exe launched automaticaly at each start up of a computer and stopped immédiately after :
function : create a desktop wallpaper with the information you may need, color wished etc...
Then you can have: user name, host, group, IP, MAC...
you can chose position and size of all this.
for me top right, about 1cm height characters (i can see them in real from my desk and from veyon also)

Good luck

@tobydox said in Veyon for endless os:

AFAIK Flatpak does not support systemd services (only systemd user units supported). However the Veyon Service is required to run with root privileges and interact with the systemd logind manager. So all we could package is Veyon Master which wouldn't help that much since you'd always have to install the Veyon Service (and Veyon Configurator) additionally.

oh... Was about to ask the same thing about using a Snap package but I'm guessing it would be the same.

@tobydox After further investigation, the student's are able to bypass the firewall. For example, students accounts are prohibited from visiting Reddit.com. However, if the teacher computer is running Veyon, the client can go to Reddit and the firewall records it as traffic under the teachers account. This is a serious issue for us.

If the teacher computer is not turned on, filtering works correctly.

Thanks and regards..

@tobydox I don't see where to add the parameter. I switched to advanced mode, under "service" I don't see any place to add a parameter under the VNC server section.

it would be great to have a solution 🐶 so how to do it...

Unfortunately there are limitations by the VNC protocol which could lead to the latencies you've described. Where do you observe the latencies? In the monitoring view with thumbnails or also while remote controlling/viewing a computer?

@tobydox Thank you for this information! 😊 👍

FYI: the issue has been fixed in Veyon 4.5.6.

Thank you for sharing your findings!

That's an interesting feature but currently not implemented. Maybe the network discovery add-on would be useful in this case? It will however group/show all computers in the network so I'm not sure if this is what you're looking for.

As written elsewhere already, nested AD groups are supported by Veyon 4.5.6 and newer.

Certain Veyon features can only be disabled globally in the configuration (https://docs.veyon.io/en/latest/admin/reference.html#features) so if student workers work on computers different from the lab management staff, you could deploy a modified Veyon configuration on these computers. Restricting functionalities to certain groups however is currently not possible.

@tobydox Thank you very much.
