GCE Debian 7, X11 Forwarding over SSH problem: solved

This is my first time using Google Compute Engine.

My plan was this: using GCE running Debian, and all Graphical User Interface should be forwarded to my Microsoft Windows desktop. Of course on Debian (Linux), XWindows (X11) over SSH is the most secure and mature method to me.

Then, it became an 18-day struggle for myself, because it did not work at all!

Today, I finally installed the same Debian 7 operating system inside a virtual machine using VMware Player. Of course, with default installation, X11 forwarding over SSH works perfectly inside this virtual machine. And then, I can start to compare the differences between the working Debian and that of my GCE instance. Now I found where the problem was.

Translation of my previous post: My inspiration from a hatched chicken breaking through the shell

This post is a translated version from my previous post in Han language.

We saw this video on YouTube when I was explaining to my daughter about the process of the eggs hatched into chickens yesterday.



At around 3:29, the shell of the second egg was broken from inside.

My daughter raised a very enlightening question: “What would happen to the chicken, if it cannot break through and walk out of the shell?”
