Probleme connexion VNC via tunnel SSH

Bonjour,

Je suis sur ubuntu 12.04 et je voudrais me connecter ac VNC via tunnel SSH pour controler une machine egalement sur Ubuntu 12.04. Je parviens déjà à me connecter par SSH à cette machine avec la simple commande

ssh -CX "user"@"password"

mais en suivant les différentes documentation (notamment remmina http://community.linuxmint.com/tutorial/view/83), je ne parviens pas a me connecter ac VNC. J'ai déjà coché l'option dans la machine serveur "permettre les connexions a distance".
Quelqu'un pour m'aider s'il vous plaît?

23/11/2013 10:31:32 ------------------ USEFUL INFORMATION ------------------
23/11/2013 10:31:33 X DAMAGE available on display, using it for polling hints.
23/11/2013 10:31:33   To disable this behavior use: '-noxdamage'
23/11/2013 10:31:33 
23/11/2013 10:31:33   Most compositing window managers like 'compiz' or 'beryl'
23/11/2013 10:31:33   cause X DAMAGE to fail, and so you may not see any screen
23/11/2013 10:31:33   updates via VNC.  Either disable 'compiz' (recommended) or
23/11/2013 10:31:33   supply the x11vnc '-noxdamage' command line option.
23/11/2013 10:31:33 
23/11/2013 10:31:33 Wireframing: -wireframe mode is in effect for window moves.
23/11/2013 10:31:33   If this yields undesired behavior (poor response, painting
23/11/2013 10:31:33   errors, etc) it may be disabled:
23/11/2013 10:31:33    - use '-nowf' to disable wireframing completely.
23/11/2013 10:31:33    - use '-nowcr' to disable the Copy Rectangle after the
23/11/2013 10:31:33      moved window is released in the new position.
23/11/2013 10:31:33   Also see the -help entry for tuning parameters.
23/11/2013 10:31:33   You can press 3 Alt_L's (Left "Alt" key) in a row to 
23/11/2013 10:31:33   repaint the screen, also see the -fixscreen option for
23/11/2013 10:31:33   periodic repaints.
23/11/2013 10:31:33 
23/11/2013 10:31:33 XFIXES available on display, resetting cursor mode
23/11/2013 10:31:33   to: '-cursor most'.
23/11/2013 10:31:33   to disable this behavior use: '-cursor arrow'
23/11/2013 10:31:33   or '-noxfixes'.
23/11/2013 10:31:33 using XFIXES for cursor drawing.
23/11/2013 10:31:33 GrabServer control via XTEST.
23/11/2013 10:31:35 
23/11/2013 10:31:35 Scroll Detection: -scrollcopyrect mode is in effect to
23/11/2013 10:31:35   use RECORD extension to try to detect scrolling windows
23/11/2013 10:31:35   (induced by either user keystroke or mouse input).
23/11/2013 10:31:35   If this yields undesired behavior (poor response, painting
23/11/2013 10:31:35   errors, etc) it may be disabled via: '-noscr'
23/11/2013 10:31:35   Also see the -help entry for tuning parameters.
23/11/2013 10:31:35   You can press 3 Alt_L's (Left "Alt" key) in a row to 
23/11/2013 10:31:35   repaint the screen, also see the -fixscreen option for
23/11/2013 10:31:35   periodic repaints.
23/11/2013 10:31:35 
23/11/2013 10:31:35 Client Side Caching: -ncache mode is in effect to provide
23/11/2013 10:31:35   client-side pixel data caching.  This speeds up
23/11/2013 10:31:35   iconifying/deiconifying windows, moving and raising
23/11/2013 10:31:35   windows, and reposting menus.  In the simple CopyRect
23/11/2013 10:31:35   encoding scheme used (no compression) a huge amount
23/11/2013 10:31:35   of extra memory (20-100MB) is used on both the server and
23/11/2013 10:31:35   client sides.  This mode works with any VNC viewer.
23/11/2013 10:31:35   However, in most you can actually see the cached pixel
23/11/2013 10:31:35   data by scrolling down, so you need to re-adjust its size.
23/11/2013 10:31:35   See http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching.
23/11/2013 10:31:35   If this mode yields undesired behavior (poor response,
23/11/2013 10:31:35   painting errors, etc) it may be disabled via: '-ncache 0'
23/11/2013 10:31:35   You can press 3 Alt_L's (Left "Alt" key) in a row to 
23/11/2013 10:31:35   repaint the screen, also see the -fixscreen option for
23/11/2013 10:31:35   periodic repaints.

23/11/2013 10:31:35   If this makes the key mapping worse you can

Re : Probleme connexion VNC via tunnel SSH

Voir la doc suivante : cliquer ici.
Il y aurait un paramètre dans la commande ssh qui permet de rediriger le port "vnc" (-L).
