License Activation

While installing X-Win32, allow the Windows Firewall additions if asked. When starting X-Win32 for the first time, the License Activation Window will appear. Choose License your copy by contacting a license server. Enter Hostname: and Port: 5053

License Activation Window

The X-Win32 license server uses ports 5053 and 5055. Check your firewall if the license fails to activate (X-Win32 closes after 30 minutes.)

Creating A Connection

  • Configure connections with the X-Config option after activating the license.
  • Under the Connections tab, click the Wizard button.
    Name your session. Click ssh in the Type: box   Click Next
  • Enter the Host to connect to, ie:   Click Next
  • You may enter a Login and Password. I suggest leaving the Password blank. This prevents someone from accessing your account by just clicking the connection name!
    Click Next
  • Click the system the remote host uses. Edoras uses the Linux XTERM command
    Increase the scrollback buffer by adding -sb -sl 1000 to the xterm command line.
    Click Finish
  • Notes

      The default xterm font size can be increased if desired. Increase the xterm font size by editing the XWin32 connection settings. For example: /usr/bin/xterm -fa 'Monospace' -fs 18
      The license activation window is found by starting X-Win32, then right click on the X-Win32 icon in the system tray, then select Help -> Activate License.
      X-Win32's ssh client does not include a file transfer utility (sftp). We recommend installing the free WinSCP client to transfer files between your PC and Edoras.
      X-Win32 license expires June 30, 2026.
      The X-Win32 connects using port 22. Check your firewall if you can't connect to Edoras.
