Norsk versjon - X-win 32

Software information

X-Win32 makes it simple to make different types of X Windows connections (XDMCP, REXEC, SSH, etc.) to remote Linux and Unix servers. It uses the graphic interface X-windows and associated software from a Windows computer.

License information

Site license: Available to all students and employees.

Used by some faculties at NTNU.

Note that the program can only be used for academic work and not for commercial work.


Using the program

The X server is started from All Programs --> X-Win32 --> X-Win32. When the program has started, an icon will appear in the bottom right on our screen, on the toolbar. By clicking this icon we will get a few different options, including Help. For more help, see StarNet Knowledge Database

Setup of a connection is done by starting the X-Config from the same menu the program is started from, or by right-clicking the X-Win32 icon we talked about before, and choosing X-Config. All settings can be done in the X-Config interface. An instance of settings are saved as a Connection.

A Connection can be changed by choosing Edit in this window. Setting up a connection is done by right-clicking the X-Win32 icone in the toolbar and choosing a Connection we have made, or choosing Connection and then Launch in this window.


As long as the computer you want to connect to is configured with support for x-forwarding, you can log into the computer and run programs through SSH. You can use X-Win32 to set up an SSH connection by doing the following steps:

  • Use the X-Win32 wizard, and choose SSH as Connection Method.
  • Choose a name for the connection.
  • Press Next, and write in the hostname for the server. (ex.
  • Press Next, and enter your NTNU username and password.
  • Press Next, and choose operating system. Press Finish.
  • Click the icon that was added to the list, and choose Launch to start a terminal.

You can also choose to simply run the X-server and use a different SSH client than the one bundled with X-Win32. Most SSH clients will support x-forwarding.

Error messages

If you get an error message saying the following;

Xlib: connection to "localhost:16.0" refused by server
Xlib: Client is not authorized to connect to Server

it's because the machine you're trying to connect to is trying to connect to your X server, but is unable to authorize it. The solution is to add the machine to the X-Host list. You can find this list under the Security drop down menu in the X-Win32 Configuration window.

Screen Shot

Mark the option Screen Shot when you right click the X-Win32 icon.

You can take a screen shot of either the entire screen, a spesific area, or a window. The screen shot can be printed, added to the clip board, or saved as a file in the .PNG format. Note that you can take a screen shot of everything on the screen, not just the windows from the UNIX machine you have access to through X-Win32. For more information about screen shots, see HELP.
