运行于Unix/Linux上的软件，越来越多地采用图形界面，特别是软件安装和应用管理。这得益于java，虽然java的图形界面非常丑陋，但确实极大地降低了开发的门槛。

那么，远程如何启用xwindow呢？下面介绍的就是一个基于cygwin上xwindow+openssh的方案。

Displaying remote X clients with Cygwin/X

Displaying remote X clients with Cygwin/X is nearly identical to displaying remote X clients with any other X Server. You may use the secure ssh method, or the unsecure telnet method (not recommended).

Secure ssh

On your Windows machine:

  1. Make sure you have the openssh package installed.

  2. Launch Cygwin/X

  3. Run the following in an X terminal:

    Username@CygwinHost ~
$ ssh -Y -l username remote_hostname_or_ip_address

  4. Enter your password when prompted by ssh.

  5. Your ssh session should now show you a shell prompt for your remote machine.

  6. You can now launch remote X clients in your ssh session, for example, xterm& will launch an xterm running on your remote host that will display on your Cygwin/X screen.

  7. Launch other remote clients in the same manner. I recommend starting the remote clients in the background, by appending & to the command name, so that you don't have to open several ssh sessions.

Unsecure Telnet

On your Windows machine:

  1. Make sure you have the inetutils package installed.

  2. Launch Cygwin/X

  3. In an X terminal type /usr/X11R6/bin/xhost remote_hostname_or_ip_address

  4. In an X terminal type /usr/bin/telnet remote_hostname_or_ip_address. Use the explicit path to ensure that Cygwin's telnet is run instead of Microsoft's telnet; Microsoft's telnet will crash on startup when run from Cygwin/X.

  5. Login to your remote machine via your telnet session

  6. In your telnet session type, DISPLAY=windows_hostname_or_ip_address:0.0

  7. In your telnet session type, export DISPLAY

  8. You can now launch remote X clients in your telnet session, for example, xterm& will launch an xterm running on your remote host that will display on your Cygwin/X screen.

  9. Launch other remote clients in the same manner; I recommend starting the remote clients in the background, by appending & to the command name, so that you don't have to open several telnet sessions.
