 Posted: Wed Mar 22, 2006 11:27 pm Post subject: [ssh] X11 forwarding (résolu) |
 |
|
bonsoir !
je me connecte en SSH avec mon laptop sur mon PC (de chez moi) et sur les serveurs de l'uni.
lorsque je le fait sur le serveur de l'uni, jarrive a lancer des applications comme mozilla, et la fenetre est "redirigée" vers mon laptop (j'adore !)
Seulement voilà, ça marche pas quand je le fais depuis chez moi.
| Code: |
alex@Gentoo_Server ~ $ firefox &
[1] 12057
alex@Gentoo_Server ~ $ xdpyinfo: unable to open display ":0.0".
No running windows found
(firefox-bin:12084): Gtk-WARNING **: cannot open display:
firefox-bin exited with non-zero status (1)
[1]+ Exit 1 firefox
|
J'ai regardé sur ce tuto , j'ai essayé de bidouiller le /etc/security/pam_env.conf mais rien n'y fait.
j'imagine que la manipulation a faire est uniquement sur le serveur, vu que ça marche si je fais un ssh sur l'uni.
j'ai regardé ce bug mais j'ai pas pigé grand chose, à part que ça a un rapport avec mon erreur ...
help !
thx.

c'est dans /etc/ssh
vérifie ssh_config et sshd_config : active "ForwardX11" et "X11Forwarding" ; puis redémarre sshd et ta session ssh

j'ai modifié , et ça n'a rien changé 
| /etc/ssh/ssh_config: |

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

Ha oui, autre chose : tu dois aussi autoriser les flux X : sous gnome : /etc/X11/gdm/(je ne sais plus par coeur) , tu dois activer TCP (mettre décommenter TCPDissallow et le mettre à "No") ; et bien sûr redémarrer xdm

Je ne trouve pas le fichier pour le TCPDisallow et je n'utilise pas gnome, donc y'a rien dans /etc/X11/gdm , je vois pas où chercher d'autres, car il n'y pas de directory /etc/X11/kdm ...

si le forward fonctionnait, tu aurais :10 à la place de :0 ...
chez moi, cette config suffit pour fonctionner, je n'ai pas d'autres idées
