Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm trying to force an xterm to open from a remote host, D, over an SSH connection between boxes B and C, to display on my windows PC, A.
Box A, the windows PC has a windows-based Xserver (EOD). I connect to box B and run Gnome. From box B, I run ssh -Y C xterm -ls. So then I get an xterm from box C running through the window manager on Box B, displaying on Box A.
Box D is the difficult part. It cannot route to Boxes B or A, and it doesn't have SSH installed. I can open an xterm to its local display, and I can open an xterm pointed back to a X11 tunneler on Box C, xmond, which then gets displayed back to box A. (I connect to Box D from box C using RSH and Telnet)
I'd like to get this xterm from box D running through the SSH tunnel between boxes B and C. Instead, when I run xterm -display C:10, I get this error: "X11 connection rejected because of wrong authentication." Ultimately, I'd like to run a proprietary X11 application over this tunnel, just using xterm to get started.
Has anyone been able to use an SSH tunnel between two boxes to route X11 from a third?
Distribution: Ubuntu 11.4,DD-WRT micro plus ssh,lfs-6.6,Fedora 15,Fedora 16
your method of ssh from a to b, run the window manager, then run an Xterm on box b, and ssh with X forwarding into box C seems the most logical, but yes, you could look into iptables to forward say, port 23 from box a to port 22 on box c via box b
