      I’m not familiar with Veyon throughput or whether this is configurable. Generally I haven’t experienced performance issues using either Fullscreen demo or Window demo and though deselecting unused computers would achieve a modest performance gain my experience has been this doesn’t work very well on the fly. Since you are down to two lists I think it would be best to exit and restart Veyon whenever your selections change.

      @tobydox said in Veyon 4.5.1 I can't open website from Master:

      Some technical background: first you should make sure the tray icon is visible on all computers. If it's not visible, the Veyon Service for some reason is not able to run it's own worker processes within the user session. The Veyon tray icon is provided by such a worker process. Launching the "Run program" or "Open website" features also launches a (different) worker process inside the user sessions as a helper process. This worker will then start the program or open the website and this way make sure the program or browser is opened with user privileges (instead of Admin/LocalSystem privileges which the Veyon Service is running with).

      On computers where the tray icon is not visible, can you please check the VeyonServer.log file for messages starting with WindowsCoreFunctions and post them here?

      Try turning off the Windows Defender Firewall (Domain Network) for one of the Windows 10 computers and try again.

      No problem, you can't be on dev and forum at the same time
      Your job is really helpful for a lot of people, thanks for that.

      I'd like to be more useful here on the forum, but not "good" enough yet with veyon to help much people.

      A tech at a neighboring school advised that rather than entering IP addresses into the Configurator’s Host address/IP field (Locations & computers) to instead enter computer names.

      A bit confusing to me but he said to make the Host address/IP field match the Name field when using DHCP assigned addresses.

      Veyon for Raspbian?

      @tobydox said in Veyon for Raspbian?:

      this is an interesting use case! Building packages for Debian (no matter which platform/architecture) isn't that complicated, just
      have a look at our README file. Besides that we recognized the growing demand for armel/armhf/arm64 binary packages so we
      might provide them in the future as well.

      Be aware that Raspbian has its own non-standard ABI.
      In standard Debian armhf means ARMv7 instructions with hardware floating point.
      In Raspbian all Debian packages have been rebuild with ARMv6 instructions, for compatibility with older Pi that do not understand the newer instructions.
      They do are compiled with hardware floating point, so it is not armel either.

      Any chance you will be maintaining an official Debian package submitted to Debian at some point instead of the current situation?
      That would simplify things. Let the Debian derivatives do the compiling, and allow users to just apt-get it.

      Hello tobydox

      I have created an environment variable in the operating system with a value equal to 2

      SET VEYON_SESSION_ID = 2

      And also in the veyon-client environment.

      veyon-cli config set Service/VEYON_SESSION_ID 2

      My session ID is two

      QUERY SESSION

      SESSION NAME USER NAME ID STATE
      services 0 Desc
      rdp-tcp # 2 administrator 2 Active
      console 3 Conn
      rdp-tcp 65536 Listen

      And in no case have I managed to make the screen that shows to the students the session in which the teacher works.

      I have also test with the new version of Veyon 4.4.0

      I would like to remind you that both the students and the teacher are working on their own virtual desktop connected by RDP, that is, they are all in session 2 of their own virtual desktop.

      @DrewLoker this is already possible - simply enable the "Show confirmation dialog for potentially unsafe actions" option in the master configuration page in Veyon Configurator - see https://docs.veyon.io/en/latest/admin/reference.html#behaviour for details.

      I just switched in General from "use system language" to English US... My local language GUI was really annoying in both Configurator and Master, and in older versions there was no English option for some reason.

      In 4.1.0 I just noticed there is English. The moment I switched to English and reopened Configurator, clicking "Start service" worked right away

      The line
      [WARN] WindowsServiceControl: 'VeyonService' could not be started.
      is not showing anymore in .log

      So far no errors, everything looks fine. Going to install it on few class PCs and see if Master works without issues.

      @Tuisku
      there was indeed an old bug which always made the Veyon Server crash with language set to Hebrew. This has been fixed in the code and a temporary test release is available at https://github.com/veyon/veyon/releases/download/v4.2.1/veyon-4.2.1.26-win64-setup.exe - feel free to test and report back!

      After updating to Veyon 4.5.1 the overlapping issue has not recurred. Everything is working perfectly.

      Thank you.
