08/01/2019 16:32:39    - use '-nowf' to disable wireframing completely.
08/01/2019 16:32:39    - use '-nowcr' to disable the Copy Rectangle after the

The VNC desktop is:      laurent-MS-7522:0
PORT=5900

******************************************************************************
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching

Puis je laisse la console active de la connexion ssh au serveur depuis la poste client.et j'ouvre un nouvelle onglet dans la console et tape

valerie@serveur-MS-7522:~$ vncviewer 78.xxx.xxx.24
vncviewer: ConnectToTcpAddr: connect: Connection timed out
Unable to connect to VNC server
valerie@serveur-MS-7522:~$ 

Ca ne fonctionne pas, comment faire ?
Parcontre en réseau local ça fonctionne.

Merci.

Re : Connexion à VNC impossible à distance depuis internet ?

Salut,
Ton poste manque de précision et d'explication.
Je que je peux te dire comme ça, c'est qu'il te faut un transfert de port (NAT) sur ta passerelle réseau pour accéder au réseau local depuis l'extérieur.
