In order to use X-win, there is a catch at the moment. You also need software known as SSH (Secure Shell), which is like telnet in that it allows you to talk to other computers, but as the name implies, it encrypts your computer's conversation with other computers, thus making it much harder for anyone `listening' to take your passwords, or any other important information. SSH and X-win can both be obtained free of charge from the Rice IT Software Page http://software.is.rice.edu. Don't forget to get a license key from the license page http://software.is.rice.edu/License/index.html. For X-win and other software by OS, click on the links at the bottom. SSH also includes an encrypted FTP program, giving you a graphical interface that allows to to easily see and select the files you wish to move. Michael Swartz has put together a two help files that show how to set up both X-win and SSH.
