Components and Session Overview

A GO-Joe session involves several components working together to bring X Windows to network computer desktops:

• The network computer client(s)

• The X-to-RapidX converter (or RapidX server)

• A Web server to deliver the GO-Joe applet

The RapidX server and the web server could conceivably reside on two different machines. However, Netra j automatically configures them both on the same machine. Netra j also provides an example X session. The GO-Joe session proceeds as follows:

1. You enter a URL in the client system's browser or Java environment loading the HTML page containing the GO-Joe applet from the Web server.

2. The GO-Joe applet prompts you for a login and password to authenticate you to the RapidX server.

3. When you click the Start X Session button (or press Return, depending on the browser), the login and password are sent to the RapidX server at the port specified in the HTML page loaded in step 1.

4. The RapidX server accepts the applet's connection and passes it off to the go-login program.

5. The go-login program receives the user name and password specified in Step 3. If the user name and/or password are incorrect, an error is returned by the applet and it returns to Step 3.

6. If the user name and password are valid, the go-login program starts an X session with special arguments initiating its use of the GlobalHost loadable ddx module.

7. Initialization scripts check for a GO-Joe token, and if present, modify the session startup behavior as specified by the controls in the token parameter.

After these steps, the session is displayed within the GO-Joe applet and you are able to run X clients from the UNIX network.
