Connect to a running/existing X session remotely

вт, 11/08/2009 - 16:30 — vladimir

From the computer you want to view the remote X session:

ssh root@computer2 -L 5900:localhost:5900

This does not need to be done as root, but you’ll need to be the actual user running the X session if you log in as a regular user. On ubuntu/debian you can use apt-get install x11vnc.


x11vnc -display :0 -passwd password

If it complains that it cannot connect to :0, try this


x11vnc -auth /var/lib/gdm/:0.Xauth -passwd password

Note that using the :0.Xauth method will work if X is just running at the login screen (so you could connect and log into X as a user).

Now, from computer1, do


vncviewer localhost

This is very useful, but make sure you use a password if port 5900 is open on computer2.

Festplattenrettung in Berlin

пн, 24/11/2008 - 11:38 — vladimir

Neulich einen Auftrag bei

http://xdatenrettung.de/

abgegeben und sehr angenehm überrascht worden -
zum Fixpreis von 900 € wurden die Daten von der alten Platte (Mechanik im Eimer)
gekratzt und auf eine andere(neue) kopiert.

Die (große) Konkurrenz - das was man so in Fachmagazinen findet etc. hätte ab 2000 € gekostet.

Hut ab!
