Yes, it is possible to take screenshots using Veyon-cli. Veyon provides a command-line interface (CLI) that allows for various actions, including capturing screenshots, on remote computers. You can use the veyon-cli tool to send a screenshot command to a specific computer or to all connected computers.

@Bilgediver said in Performance considerations for network: As far as I can tell Veyon uses self-hosted VNC. As far as I know VNC is between client and server, there is no inbetween. The only way that would work (in my head) would be to set it up on a server, then you use your instructor computer to remote into the server to view everything. I just tested it on our network and you can use Veyon on your Instructor computer to remote into the Server Installation of Veyon, and use the Server Veyon to view all of the other computers. Thank you so much for this input!! Although I don't really have a specific deadline for getting this setup, ideally it'll be setup before summer break kicks in, because we have summer day camps that will use the computer lab much more heavily than during the school year. So I'm gonna definitely slot out some time here within the next month or so to get this all fully figured out. Again, I appreciate this! Helps me greatly in getting a better idea of if Veyon may be a high potential solution for our needs. Thank you!

@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?

@Antoine Yes, the core solution is free, as Veyon is open-source, but some advanced features or enterprise support may require additional costs. You can use the main functionalities without paying, but addons or custom integrations might come at a price. Regarding audio monitoring, Veyon does not support direct audio listening from remote PCs, including VoIP calls. It primarily focuses on screen monitoring, remote control, and classroom management. If you need to monitor audio, you may have to look for third-party solutions designed for that purpose. Hope this helps!

@AbrBahen I was in a similar situation with my website, and I managed to resolve it. The best approach is to check if there's a password recovery option on the login page—most platforms have a "Forgot Password" feature that allows you to reset credentials via email. If that doesn't work, try contacting customer support directly. Provide them with details about your organization, such as the email address associated with the account or any proof of ownership. In my case, I had to verify my identity and ownership through billing details or domain registration records. If your previous staff member used their personal email, you may need to request an update from support. I recommend reaching out as soon as possible to avoid any delays. Hope this helps!

Hello, This would also be an interesting feature for me but as for now I have not found an option to diasble it. Anyone an idea?

If your systems are already connected to a Domain Controller (DC), Veyon will automatically integrate with Active Directory during setup. Your IT specialist should have configured this when installing Veyon. Once this integration is complete, students can log in with their DC accounts without any additional steps needed.
