Re: XDMCP chooser in linux.. as solaris

Hello again:

No luck trying to obtain any way to connect to remote xdmcps using
gdmchooser.  For this reason I had created the following shell script.

This script is  called without parameters. Only will run correctly if all X
remote sessions are launched with xinit executions. In a few words, this
code obtain the greatest $DISPLAY value from all remote sessions, add 1 to
this value, executes gdmchooser and if a server is returned, tries to
launch xinit with the necessary values.
If firewall rules in both local or remote machines blocks X protocol, you
will only obtain a gray or black screen with the mouse pointer.

Tehory of operation:

     Suppouse that you have your machine up and running in graphic mode.
Have xhost +<lan or ip range for servers that you wanna connect >,
and firewall rules that permit X protocol. Of course, you have gdmchooser
     Execute the xrchooser script


     If all goes well, you will obtain the gdmchooser screen. If the Close
button is pressed, the script finishes with 'No server selected from
gdmchooser' message.
     But if a server is selected from gdmchooser, the script executes a
xinit call with this form:

     # first assign a new value to the DISPLAY environment var. This value
is the highest display used by any xinit process currently running,
     # to this value 1 is added to get the next DISPLAY value unused. If no
earlier xinit processes are executing, the :1 value is assigned to DISPLAY
     # by default.
     export DISPLAY=localhost.localdomain:<display_value>

     # And xinit is called in background

     xinit -- -query <gdmchooser_selected_server> :<display_value> &

     Then the display offers the remote server gui login.

     You can work with different Xsessions at the same time. Only need to
know the following equivalence:

      If DISPLAY=:0 ( the default X session in your machine), then the
screen is located at Ctrl+Alt+F7
      If DISPLAY=:1 ( the default X session in your machine), then the
screen is located at Ctrl+Alt+F8
      If DISPLAY=:2 ( the default X session in your machine), then the
screen is located at Ctrl+Alt+F9
      And so...

     When you have finished to work with this X session, then logout from
session to obtain the remote gui logon again. Then you can kill this X
remote session
     with Ctrl+Alt+Backspace. This only kills the actual session, not
others, but if you kill your local sesission, all other will die, of

     When xinit is called, one xterm is created in the local X session. If
you close this term, the X sesion dies. May be is possible to avoid the
xterm execution.
