Re: [X2go-user] Hooking Up To A Running X-Session

Hi Axel, <snip> The second usecase is more tricky than the first. X2go shadow session
(that's what the guest user sessions are called) have only been
implemented quite recently. They are not available in the lenny
repositories. Use these two (both!) line in /etc/apt/sources.list (on
server and linux clients):

deb http://x2go.obviously-nice.de/deb lenny main deb http://x2go.obviously-nice.de/deb heuler main

On the server you currently have to install (this will change in the
near future):

Debian: apt-get install x2goserver-one x2godesktopsharing x2gognomebindings
x2goplasmoid

Ubuntu: apt-get install x2goserver-home x2godesktopsharing x2gognomebindings
x2goplasmoid

On the client you simply need the x2goclient package:

apt-get install x2goclient

YOU:

On the server you have to start the x2godesktopsharing util that will
dock to your systray panel. Make sure you allow other to knock on your
door.

YOUR GUEST:

The guest user first of all needs an SSH account on the X2go server.
Hope, this is not a hurdle. The guest user then has to start a
shared/shadow session from his local x2goclient app. The session name
for this in the session profile preference is:

,,Connect to local desktop'' ,,Zugriff auf lokalen Desktop'' in Deutsch

So, instead of using GNOME or KDE your guest user has to use either of
the above with the hostname, port, username etc. of your X2go server.

If the guest user then starts a session, he/she will knock on your
x2godesktopsharing icon virtual door and you can decide to let him/her
in or not. <snip> We take a slightly different approach - and that is exactly what it is - different - not better or worse. In our case, we want our users working in their virtual desktops all the time and the virtual desktops are all accessed across the Internet. Thus, we did not want users to have to leave their virtual desktops to open another X2Go session in shadow mode. Instead, we placed "share desktop" and "View Another Desktop" icons on their virtual desktops which use X11VNC to share the active desktop. Thus, all activity is from within the virtual desktops.

Since the VNC connection is inside the LAN (between virtual desktops), the performance is very good and we gain the Internet boost from NX for VNC just like we do for RDP when we push Terminal Server sessions through NX. Just another way for those with environments similar to ours - John
