This is an interesting use-case. Indeed currently Veyon only reacts to mouse enter/leave events so in your case, it will never see any mouse events and therefore never hide the toolbar. Can you please submit an issue at https://github.com/veyon/veyon/issues so we can enhance the behavior of the program such that it will hide the toolbar automatically if no mouse events are received at all.

Hi! You can describe how you make this config? You set variable? And if yes, how to?

Hello,
This is a Windows login configuration on non-Veyon PCs to modify.
There should be no information from the previous user. Interactive login must be enabled :
gpedit.msc
Expand: Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options.
On the right, locate and double-click the "Interactive logon: Do not display last user name" policy.

Hello, i'll try wireshark. The problem is not on our side I think, it worked well until version 4.9. And I still use wake on lan with other apps. The MAC addresses of our computers are registered in AD attribut "networkAddress".

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

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.
