"If you're a Linux administrator and you're still using telnet for authentication, your network could be in danger. Telnet passes your user IDs, password/passphrase, and the content of your terminal sessions in the clear, where anyone with a sniffer can see what you're doing regardless of whether they have your password."
"Secure Shell (SSH) is a protocol for secure terminal sessions over the Internet. This means you can control who gets into your servers with strong cryptography, keep passphrases from being transmitted in the clear over the Internet, and strongly encrypt as well as compress terminal sesions as they happen."
"Although the Internet Engineering Task Force's Secure Shell working group (SECSH) has yet to publish any formal SSH standards, SSH version 2 is currently documented in draft form and has been implemented both by commercial and open source developers. (SSH version 1 is a different protocol with the same goals; it is still widely supported.)"
