Full Discussion: X11 forwarding through a tunnel

X11 forwarding through a tunnel
Is it possible to launch an X11 application and have it use an X11 server on the other side of a bastion host? Specifically, here's my setup:


my laptop ------------- bastion -------------- remote host

I have putty installed on my laptop. The bastion is rhel 6.5 and the remote host is CentOS 6.3. Also, putty is installed on the bastion. I have an X Server running on my laptop.

Using xclock as a test app, what works fine are these two scenarios:

Code:
      my laptop ------------- bastion -------------- remote host

[A]  X Server <------------- xclock

[B]                            X Server <----------- xclock

.. in each case I needed to set up X11 forwarding, and that is working fine.

However, what I'm really trying to get is xclock from the remote host to display all the way back on my laptop's X Server:

Code:
      my laptop ------------- bastion -------------- remote host

      X Server <------------- [       ] <------------- xclock

My tools on both the laptop and bastion are either putty or ssh.

I tried, for example, running this from my laptop:

Code:
remote% ssh -X user@bastion ssh -X user@remotehost xclock

or:

laptop% ssh -X user@bastion ssh -X user@remotehost 
remote% xclock


I thought maybe I need an ssh tunnel on the bastion, but the X11 packets seem to be coming on the ssh port (22), so I wasn't exactly sure how to set up the tunnel. I tried source port 22 destination laptop:6000 (and 6010) to no avail.

macpack

macpack(Mono 1.0)														 macpack(Mono 1.0)

NAME

       macpack - Macintosh OS X Packager for managed gui assemblies

SYNOPSIS

       macpack [options] assembly

DESCRIPTION

       macpack	is a tool used to package managed assemblies (like System.Windows.Forms or Cocoa#) that require gui availability for deployment on
       Mac OS X.

       macpack will prepare a OS X compatible bundle from the provided assembly and resources.	The bundle will include the specified assembly	as
       well as any of the provided resources (specified with the -resource: switch).

       Developers  can	specify the kind of application to produce using the -mode: argument.  This controls how the environment in the Mono class
       libraries is setup.

OPTIONS

       -a assembly

       This option tells macpack where the managed assembly that you want to bundle resides.  This option is also  used  to  point  to	the  shell
       script to launch in the case of a X11/Gtk# application.

       This is the same as just passing the assembly as an argument.

       -m [winforms,x11,console,cocoa] or -mode:[winforms,x11,console,cocoa]

       A  value indicating the kind of application: WinForms is a Winforms application running on Quartz;  X11 is an application that requires the
       X11 server to run;  console is a non-graphical application;  cocoa is an application based on Cocoa#

       -n NAME or -appname:NAME

       This option specifies the application name of the emitted bundle.  This is what you will see in Finder.

       -o DIRECTORY or -output:DIRECTORY

       This option specifies the path to output the generated Application.

       -r RESOURCE or -resource:RESOURCE

       This option can be specified multiple times.  It will place a copy of each resource into the bundles resources  directory.   Alternatively,
       you can use a comma separated list of resources.
