Si vous voulez utiliser des applications GUI avec ssh
vous devez utiliser l'option -X
ou -Y
options (utiliser -Y
):
-X Enables X11 forwarding. This can also be specified on a per-host
basis in a configuration file.
X11 forwarding should be enabled with caution. Users with the
ability to bypass file permissions on the remote host (for the
user's X authorization database) can access the local X11 display
through the forwarded connection. An attacker may then be able
to perform activities such as keystroke monitoring.
For this reason, X11 forwarding is subjected to X11 SECURITY
extension restrictions by default. Please refer to the ssh -Y
option and the ForwardX11Trusted directive in ssh_config(5) for
more information.
-Y Enables trusted X11 forwarding. Trusted X11 forwardings are not
subjected to the X11 SECURITY extension controls.
Ainsi, par exemple, pour utiliser eog
pour afficher l'image distante à /path/to/file.png
vous feriez
ssh -Y liarez@remote.host eog /path/to/file.png
