I\u25baRemote Display et Protocole X<\/span><\/strong><\/h1>\n

Un client X peut utiliser le display d’un serveur X.
\nPour rappel, le serveur X d’une machine linux est toujours d\u00e9mar\u00e9 mais le display manager (xdm, gdm, kdm) peut ne pas \u00eatre d\u00e9marr\u00e9 …<\/p>\n

Un client nomm\u00e9 HOST (172.17.112.46)<\/strong> souhaite utiliser le display manager du serveur nomm\u00e9 SRV (172.17.112.47)<\/strong> pour utilser les apllications graphiques du serveur qui n’a pas forc\u00e9ment d’interface graphique d\u00e9marr\u00e9e.<\/p>\n

    \n
  1. La commande xhost<\/strong> \u00e9x\u00e9cut\u00e9e chez le client \u00a0autorise ce host local \u00e0 utiliser un Xhost :
    \nxhost +HOST
    \nxhost +172.17.112.46<\/strong><\/span><\/span><\/span><\/li>\n
  2. Il se connecte ensuite sur le serveur en ssh avec l’option -X pour autoriser le forward de display
    \nssh -X root@SRV
    \nssh -X root@172.17.112.47<\/strong><\/span><\/span><\/li>\n
  3. Une fois connect\u00e9 au serveur, il va exporter un display vers le client ;
    \nexport display=HOST:0.0
    \nexport display=172.17.112.46:0.0<\/span><\/strong><\/strong><\/li>\n
  4. Il peut ensuite lancer xterm&<\/strong><\/span> pour afficher un termainal X qui s’affiche directement sur le bureau du client …
    \nOu bien directement dans la console lanser une application graphique comme firefox& ou libreoffice& pour l’exemple<\/span><\/strong><\/li>\n
  5. Le client uyilise alors le programme graphique du serveur qui n’a pas d’affichage mais d\u00e9porte chez le client son affichage<\/li>\n
  6. On pourra par exemple lancer le webmin du serveur sur le navigateur du client
    \nhttp:\/\/localhost:10000<\/li>\n<\/ol>\n

    Le serveur n’a pas d’affichage graphique, on ne peut pas utiliser le navigateur et webmin (s\u00e9curit\u00e9…), par contre le client prend possession du webmin du serveur en mode graphique<\/span><\/p>\n
