You'll need both X-windows server software (like Exceed, Xming, Xwin32) and a secure shell package, such as SecureCRT or Putty. Below are the steps to configure Exceed and SecureCRT:

• Once Exceed is installed:
  • Click Start -> Hummingbird -> Exceed -> xconfig (or rt. clic k Exceed in Task Bar -> Tools -> configuration)
  • Dbl click on Security icon and select "Enabled (no host acce ss)".
  • Click "OK" and close window.
• Once SecureCRT is installed:
  • Start SecureCRT.
  • Click File -> Quick Connect
  • Set Protocol: ssh2
  • Hostname:
  • SSH Server: Standard
  • Click on the "Advanced.." button -> click on the "Port Forwarding" tab and check the "Forward X11 Packets"

Exceed does not have SSH built into it. You MUST have Exceed running in order to display an "X" window back to your Windows PC. When Exceed is running, click the "Connect" button in Secure CRT and enter user name and password to connect.
