This tool replaces Telnet, rlogin and RSH while providing secure communications between hosts over insecure networks.
X-11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. It provides typical remote system administration, file transfers and access to corporate resources over the Internet. The program includes compatibility with SSH protocol version 1.5, password authentication, compression support and connection forwarding, including support for X-protocol connection forwarding.
The program also includes dynamic forwarding, a feature that lets you start FTP and other facilities through established SSH connections without direct access to remote hosts.
