my goal is simple.

"mstsc" like remote desktop through a secure connection, under Linux.

Dude, I don't really understand what exactly you are trying to accomplish, but this seems like the least efficient and highest-bandwidth method.  Passing Gnome desktop information across ssh connections is about as high a bandwidth operation as there could be.  You could generate huge amounts of lag due to the large amounts of data being passed - even on the same local network.  Also, there is a reason for turning off the DissallowTCP option as it is highly insecure.  If this is the setting I'm thinking of, it allows the trusted-ness of a remote system to be spoofed by any system thus allowing any system on a given network access to running remote applications on your system without any serious authentication.

If you are just trying to control the remote desktop (Gnome session) of computer A from computer B, maybe you would be better served by using the remote desktop applications.  You can setup the settings for computer A via System -> Preferences -> Remote Desktop and then access it from computer B via Applications -> Internet -> Remote Desktop Viewer.  Also, you could setup a stripped-down system on computer B with a basic Xorg session and xtightvncviewer.

If you are just attempting to run specific applications remotely, you can accomplish that with ssh -Y (not -X).  This uses a secure connection to accomplish Xorg forwarding - basically a secure way to get around the DIsableTCP settings.

So yea, it really depends on what your ultimate goal is.

ok, I tried: 

ssh -CX ubuntu at /usr/bin/gnome-panel

it gives me a panel, from where I can launch the applications on the remote machine, but it's still just an idea.

There is no such thing as "remote ssh gui"? :O I mean the remote machines full desktop through ssh?

thank you

client & "server" = Ubuntu 9.04
Both has GNOME GUI installed.

server []: I just install openssh-server on it, and set "DisallowTCP=false" in "/etc/gdm/gdm.config", then "/etc/init.d/gdm restart". Ok.

client: I press "Alt+Ctrl+F2", ok, then I:

$ ssh -X ubuntu at /etc/gdm/Xsession default
ubuntu at's password:

/etc/gdm/Xsession: Beginning session setup...
xrdb: Can't open display ''
Setting IM through im-switch for locale=hu_HU.
Start IM through /etc/X11/xinit/xinput.d/all_ALL linked to /etc/X11/xinit/xinput.d/default.

I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to
GPG_AGENT_INFO=/tmp/seahorse-k6FXTU/S.gpg-agent:6252:1; export

Why isn't it working? Am I missing something?

Please help..
