x server on windows

Secure ssh

On your Windows machine:

1. Make sure you have the openssh package
   installed.

2. Launch Cygwin/X, then run
   
   

   Username@CygwinHost ~ $ startxwin.bat

   
   This just starts xterm for windows users and something else. For Vista, it's really hassle to do it. Sometimes you need repeat the command many times with error message.
   

3. Run the following in an X terminal:

   Username@CygwinHost ~ $ ssh -Y(or:-X) -l username remote_hostname_or_ip_address

   
   In linux, just run last command within xterm, it will work.
   

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, firefox &, and even another
   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.

   if got errors like:
   
   "error in locking authority file .Xauthority".
   
   then run:
   
   
   

   xauth -b quit

   
   

   This will create a new .Xauthority for the user.

   Xming and Cygwin/x can do same job as X server for Windows.但是要注意,登录用户的home,即~里的文件的owner和group要属于登录用户.否则,X server can not be authorized.会出现如上的Errors.
   
   用如下命令搞定:
   sudo chown user:user .*
   sudo chown user:user *
