The CTIS systems support security. We support only software programs that utilize the Secure File Transfer Program protocol. SFTP software encrypts your username/password and the data you are transmitting. In order to upload files to our system, you need an SFTP software program.

The links below detail free and low-cost software which you can download, install on your machine, and use to transfer files between your home computer and our UNIX systems. These links also include step-by-step directions to connect and transfer files to our systems.

This is by no means a complete list of software that is available for this purpose.

Macintosh OS 8/9 - MacSFTP   ($25, 15 day free trial) *
Macintosh OS X - Fugu   (free) *

Windows - WinSCP3   (free) *
Windows - WS_FTP Pro   ($39.95, 30 day free trial)

* Indicates the program is installed in our labs.

Note: If you are using a UNIX machine like Mac OS X or Linux, and you are comfortable with the command-line interface, you have the free and built-in SFTP and SSH tools available in your shell environment. Try doing a man sftp or man ssh to learn more about these capabilities.
