We'll launch a new pricing model this year which will also include licenses for personal use. Please contact sales@veyon.io to discuss further possibilities

Exactly, it looks like KDE NEON is not fully binary compatible with Ubuntu 20.04. I suggest to build the Veyon package on your own as described here: https://github.com/veyon/veyon/blob/master/README.md#veyon-on-linux

Are you using the same logon credentials on the 2 affected teacher computers as on the other working teacher computers? Can you check that the time is synchronized on all computers properly? Besides this I recommend upgrading to the latest version (as of writing: 4.5.2) on both teacher and student computers.

The username/password of the teacher (or any other user using Veyon Master). The provided account has to exist on the remote computers (which should be default when working in an AD environment).

@itguy yep, i got upgrade my Interface to 1Gbit , theres no problem at network anymore. the problem now is, when i try controling client via Remote , sometime its fast connected, but sometimes it take about 1-2min. the respod client when i try to remote is lilbit anoying. and i didnt find where the problem is.

Does the chromebooks have Linux (beta)? Or blocked by admins?

Can you check whether you are in remote control mode, i.e. the "Send shortcut" button is visible? The remote control/view button logic may be somewhat confusing and needs to be improved.

@marcel You would probably have the default ACL applied which should by default permit all IPv4 inbound and outbound traffic. Security groups are stateful so any outbound traffic sent from an instance is allowed a return response regardless of the inbound rules you have defined. Responses to allowed inbound traffic are also not blocked regardless of any outbound rules applied. If you created and applied the security group then you will need to add the necessary inbound rules. By default this security group includes an outbound rule that permits all outgoing traffic. The default security group allows all inbound traffic (and by default all outbound traffic) unless additional rules have been applied. If you are using the default security group I would suggest removing any added rules then attempting another demo connection to see if that works. I’m assuming the demo port is 11400.

The VariantArrayMessage messages are interesting. They seem to indicate some kind of protocol incompatibility issue between master and client computers. Did you compile Veyon on your own on Linux Mint? If so, which version of Qt 5 is installed? Regarding the screenshot warning: thanks for pointing that out! I just fixed the issue which will also be part of the upcoming 4.5.3 release.

@norbinyo I mean the configuration page "Locations & computers" in the Veyon Configurator program where you added all the computers It would be interesting to see if there's a problem with hostnames.

Can you post a screenshot of the Master configuration page where you disabled some features? At a quick test I was unable to reproduce the behaviour you described. Please note that you can't delete websites/programs that you configured statically in Veyon Configurator. Only custom websites/programs opened by teachers and added after checking the "Remember" checkbox can be removed afterwards using the delete key.

I don't know if this helps ... but when I start "veyon-server" as a login-Script I get this message: [image: 1621874370270-screenshot_20210524_183807.png]

Hi, we also have implemented GCPW in our labs. At the moment we have no preblems on clients, but we are missing the login feature becuse windows is set up to try the login with GCPW while our needs would be to login on pcs through Veyon with a local user account. This seems to be impossible right now.

I do have quite the same experience with a number of 25 computers in wifi. You can probably increase the response by having the master on RJ45 network cable if possible.

@tobydox how would that even work? We have our guacamole server set up for RDP sessions, and for simplicity's sake we have every single laptop/VM set up with the exact same RDP credentials, how would we pass through the Guacamole login name or student name in guacamole as an environment variable?
