If you're still using Telnet to connect to Darkwing, Gladstone, Oregon, or other systems, you should know your username and password are at risk of being "sniffed" or "eavesdropped" upon.
SSH is a replacement for Telnet that encrypts your traffic between your desktop and the remote system you're using. You should begin using it instead of Telnet.
This year's Duckware CD-ROM has SSH software for PCs and Macs. For more information about SSH, see http://www.ssh.org/
