Free and Open Source computer monitoring and classroom management

Edit Package veyon

Veyon is a free and Open Source software for computer monitoring and classroom
management supporting Windows and Linux. It enables teachers to view and
control computer labs and interact with students. Veyon is available in
different languages and provides lots of useful features:

* see what's going on in computer labs in overview mode and take screenshots
* remote control computers to support and help users
* broadcast teacher's screen to students in realtime by using demo mode
(either in fullscreen or in a window)
* lock workstations for attracting attention to teacher
* send text messages to students
* powering on/off and rebooting computers remote
* remote logoff and remote execution of arbitrary commands/scripts
* home schooling - Veyon's network technology is not restricted to a subnet
and therefore students at home can join lessons via VPN connections just
by installing the Veyon service

      is now case insensitive.
  * Linux
    * The parameter order for the ping utility has been improved.
    * Issues regarding the session identification have been fixed,
      solving various issues when running veyon-server manually
      e.g. via autostart entries.
  * Master
    * A regression in Veyon 4.6.0 has been fixed to make the
      computer and user search case insensitive again.
    * Control messages between computers are now sent asynchronously
      which improves performance and responsiveness while reducing
      the CPU load.
    * When closing the program, it now stops all features on the
      student computers and waits until all corresponding control
      messages have been sent.
    * A new filter button has been added to show computers with
      logged on users only.
    * The dialog for confirming actions such as powering off
      computers only emphasizes ALL computers if all computers are
      selected.
    * If available, the full name of the user is now preferred in
      the tooltip.
  * Server
    * Server-side framebuffer update rate control has been added
      which improves performance and responsive.
- Update to version 4.6.0.
  * Core
    * Protocol errors during the initial authentication phase are
      handled more reliably. This fixes problems when connecting to
      incompatible servers accidentally.
  * CLI
    * The plugin and feature modules have been added.
    * The config and shell plugins have been integrated as static
      modules.
  * Plugins
    * Demo: The visual feedback when (re-)connecting has been
      redesigned.
    * DesktopServices: The Run program feature has been renamed to
      Start application.
    * RemoteAccess: The visual feedback when (re-)connecting has
      been redesigned.
    * RemoteAccess: The computer connection of the main window is
      reused if available resulting in immediate access to the remote
      computer.
    * RemoteAccess: The remote cursor is no longer used in view
      only mode to prevent occasionally observed render artifacts.
    * UserSessionControl: Non-user sessions (such as display
      manager/login screen sessions) are no longer terminated by the
      user logoff feature.
    * WebAPI: An error code has been added to report protocol
      errors occuring while connecting to the Veyon Server.
    * WebAPI: The connection limit is enforced at the HTTP server
      level already to properly report the connection limit reached
      error instead of timing out.
    * WebAPI: Skip ping for hosts which no connection could be
      established to. This allows using a higher connection limit
      on Linux when the number of open file descriptors is limited.
  * Master
    * In addition to the hostname, the computer display name is
      shown in the tooltip of a computer.
    * A computer's screen is shown in fullscreen and realtime while
      pressing and holding the left mouse button on a computer.
    * For Linux clients, [no user] is displayed as the user name
      instead of the name of the display manager user.
  * Server
    * Hostnames of connected computers
      (shown in the tooltip of the tray icon) are now reverse
      resolved in background to keep connections responsive.
  * Linux
    * SHM support is being detected more reliably.
    * Logging off users is now initiated properly through the
      environment-specific session manager while systemd-logind
      is used as fallback only. This fixes the display manager
      (especially GDM3) not being shown again after logoff.
    * Reboot and power down via systemd-logind has been improved
      while the environment-specific session manager is used as
      fallback only. The reboot and poweroff binaries are not usedany longer.
- Update to version 4.5.7.
  * Core: allow minus characters in authentication key name
  * Linux: x11vnc: auto-detect SHM support – fixes server crashing
    on start in case of lacking SHM support (no need to manually
    configure -noshm as extra parameter any longer)
