主题  SSH  Mac OS X  Apple

I  need to tunnel X Window securely over SSH bases session so that I run X program on my remote Linux/Unix server/workstation and get back display to my Apple Macbook pro laptop. I tried the  ssh -X user@server1  ssh -Y user@server2 command on both OS X Mountain Lion and Apple OS X Mavericks. But, I am unable to use the ssh command with X11

How do I fix this problem on OS X and enable X11 forwarding with ssh command ? How do I install XQuartz (X11.app) server on Apple OS X Mountain Lion or Mavericks?

You need to install XQuartz (X11.app) on OS X v10.8 or above to use ssh with x11 forwarding. The XQuartzproject is an open-source effort to develop a version of the X.Org X Window System that runs on OS X. This is Apple's version of the X server.

The latest version of Apple OS X Mountain Lion and Mavericks no longer ships with X11.app i.e. XQuartz server. You need to download and install the server before using ssh with X11 forwarding.

Step #1: Download and Install XQuartz server

Visit this page and download XQuarz server . Once downloaded the XQuarz package, install the server by double clicking the package icon in your Downloads folder. Please follow the instructions on-screen to complete the installations.

Step #2: ssh X11 forwarding syntax

A tunneling protocol is a network protocol which encapsulates a payload protocol, acting as a payload protocol. Reasons to tunnel include carrying a payload over an incompatible delivery network, or to provide a secure path through an untrusted network. SSH is frequently used to tunnel insecure traffic over the Internet in a secure way. Simply type the following command to use X over ssh:

 
ssh -X user@RemoteserverNameHere
x-app-name-here &
 

 
ssh -X userName@Server-Ip-Address-Here
x-window-app-name-here &
 

Examples

In this example, login to the Linux based nas01 server as a user called nixcraft: 
$ ssh -X nixcraft@nas01 
OR 
$ ssh -X nas01 
You will see XQuartz server in the Dock i.e. a new XQuartz icon sits at the bottom of side of your screen as follows:

To test X11 by running xeyes or xclock or any another GUI application you wish. The syntax is as follows on your remote server: 
$ app-name
$ /path/to/app-name
$ app-name &  
In this example, I am running xeyes on remote server: 
$ xeyes  
Sample outputs:

Edit your ~/.ssh/config file and append the following line and you wouldn't need pass the -X option to ssh command:

ForwardX11 yes

Finally, you can run ssh in the background after running a GUI app as follows:

ssh user@server -f -X app-Name
ssh nixcraft@nas01 -f -X gpass
ssh nixcraft@nas01 -f -X xeyes
