This is the scenario:

• A Windows XP client
• A Linux Server

The client is natted/firewalled/unreacheable from outside, the linux server is public.

I need to allow the client, once upon some conditions, to expose the remote desktop port (3389) on the Linux Server, somethig like ssh -R 3389:localhost:3389.

I dream it as a service, or something like that so I can start and stop the "forwarding-session" on my needs.

I've to pilot this session from some program-language (python or ruby mostly).

Any hint?

Thanks in advance.

I need to connect via remote desktop to a Windows XP machine (logging out the current user), do some stuff, and then log out the remote desktop session and having a user X who logs in (from the front-end I mean).

I'll try to be clearer:

I have some Windows XP machines which offer some interactive information in public places. I need to remote dekstop them to do some assistance, and then I'd like to log out and have the main user (the one who offers the service) logged back. I know there's a command for the windows prompt to achieve this, but cannot find it out!

I've got a central server (linux based) and many clients (Windows XP Embedded, afaik) in public places around my country. I need to have these clients to connect to the server with a "reverse" tunnel, that is to say that I need to control the clients from the server but the connection is initialized by clients.

The requirement is that, during the connection, an overlay image (or something like that, like a modified version of login screen) is displayed. Some stuff like "Work In Progress".

My first idea was to use vncviewer -listen and vnc in reverse mode, but cannot understand how to obfuscate the work I'm doing. Other idea was to use rdesktop in "reverse" mode, but it seems it does not support it.

Using rdekstop reverse seems the nicest solution (I can login back the user was in before connection, the login manager - which I can modified - is displayed), but any hint will be appreciated!

Thanks in advance!
