x11vnc, alternative Linux à RealVNC

Mis à jour le

Notre avis

x11vnc is a solid replacement for RealVNC if you need to expose an existing X11 session or a virtual display on a Linux box. It handles the core VNC protocol, supports password and TLS, and can run headlessly as a service. It is best suited for system administrators or developers who already run X11, not for users who want a turnkey Windows‑style VNC server with a GUI configuration tool.

Ouvrir vos fichiers RealVNC

RealVNC stores its server settings in a proprietary configuration file (.vnc or .conf) that x11vnc cannot read. You will need to reconfigure x11vnc manually using command‑line options or a custom config file; there is no direct import/export tool.

Passer de RealVNC à x11vnc, étape par étape

  1. 1. Install x11vnc from your distribution’s package manager (e.g., apt install x11vnc).
  2. 2. Create a password file with x11vnc -storepasswd and note the location.
  3. 3. Start x11vnc with desired options, e.g., x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pass -rfbport 5900.
  4. 4. If you need it to run on boot, create a systemd unit file or add the command to /etc/rc.local.
  5. 5. Test connectivity from a VNC client on another machine.
  6. 6. Disable or uninstall the old RealVNC server to avoid conflicts.
