Another temporary workaround is to use the custom computer arrangement to create a "gap" in the middle of the 4 computers we have selected for that individual display TV, that way only 1 instance of Veyon Master needs to be open. This looks like its the more likely temporary solution we'll use.

(and for the demonstration, we'll often have the students name on the computer number in notepad in the middle).

You can "Start Application" using %USERPROFILE% environment variable.
For this You need to start it using cmd:

cmd /c start "" "%USERPROFILE%\program.exe"

This will work

Hi, I haven't used Veyon that much, but I remarkably familiar with WOL issues on OptiPlex PCs
Some of our OptiPlex don't WOL until You unplug it from AC power and wait for a minute.

But since You say WOL is working from another application, but not working from Veyon, I suggest you install Wireshark and just observe that Veyon generates network packets correctly. If it does problem is on Your side, make sure You've enabled all WOL features in Windows, and UEFI. And check the firewall - it may be blocking outbound WOL packets for some reason.

Valid variables are %type%, %name%, %host%, %mac% and %location%. Various examples are given in the command help (veyon-cli networkobjects help import).

from docs..

Construct each line as following - do not include header, do not separate with spaces Computer15;10.23.15.15;"Conference2"

note the quotes
2. Go to "C:\Program Files\Veyon" open cmd in this folder
command:

veyon-cli networkobjects import "FULL PATH TO CSV FILE HERE" format "%name%;%host%;\"%location%\"" You should see [OK] on the command line Read the docs for better understanding

issue 913 on github explains it - I cannot post any link

Close configurator if it's open Create csv file where each line is like this:
pc0;10.88.17.0;"class1"

here pc0 will be visible in Master interface, 10.88.17.0 IP Address, but it can be hostname, last "class1" - note the quotes is the name of the location

Once You have csv file go to "C:\Program Files\Veyon" open cmd there:
command:
veyon-cli networkobjects import "PATH TO YOUR CSV HERE" format "%name%;%host%;"%location%""

You will see [OK] on command line
4. Open Configurator and check

No they don't have the same keys

Hello,
In our organization, we fill in the attribute "location" in the SAMBA-AD attribute of a computer.

Then in the Veyon Configurator, in the LDAP Basic/Advanced parameters page, for the identification of the location of a computer I choose "Location Attribute in computer objects" (or something similar as mine is set in french language)

Also, in the LDAP Basic environnement paramaters page, for the field "Computer Location Attribute", I fill in "location". (not sure this last one is mandatory - I can' recall exactly as it is some time I have worked on these settings).

All the settings are set at the installation of Veyon with a json file preconfigured passed as an option to the Veyon installer , so everything is set automatically provided the AD has been fulfilled.

Veyon itself does not have a built-in feature to block specific websites, but you can achieve this through other methods. One option is to configure your network’s firewall or router settings to block specific URLs while keeping general internet access available. Another approach is to use web filtering software like OpenDNS, K9 Web Protection, or your school's content filtering system to restrict access to certain sites. Additionally, you can set up browser extensions or parental controls to limit website access on student machines. While Veyon allows you to monitor and control student activity, you can also use its screen-locking or application-control features to minimize distractions during lessons. Hope this helps!

Hello,
(I'm just a user like you.)

To do that with Veyon, you have to purchase the Internet Access Control plugin.

I have the same issue but my PCs have the latest veyon, 4.9.3, win 10 and file key authentification. Some PC have a duplicant screen from a working machine, some only gray all time. I tried clean reinstall windows, doest help, all settings same. Host names are unique and the veyon ports are open.
