Getting Started
  1. What is Telnet?
  2. What is SSH?
  3. What is RLogin?
  4. What can GTelnet do?
  1. The telnet command is used to communicate with another host using the TELNET protocol. With telnet, you can have a remote shell in another computer. For example, you have to update some files at the university or your work place. Then you can do it by telnet-ing the remote computer and do the work within its shell with vi, emacs, etc.
  2. (From SSH Manual) SSH is a truly seamless and secure replacement of old, insecure remote login programs such as rlogin or rsh.  According to the official SSH (Secure SHell) site, SSH is "the secure login program that revolutionized remote management of networks hosts over the Internet. It is a powerful, very easy-to-use program that uses strong cryptography for protecting all transmitted confidential data, including passwords, binary files, and administrative commands.", and SSH2 is "the sequel to the award winning SSH1 protocol. It provides a set of radical improvements to SSH1. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. To learn more about SSH, you can visit http://www.openssh.com or http://www.ssh.com
  3. RLogin is kinda similar to telnet. RLogin is rather insecure though.
  4. GTelnet is the frontend to all these 3 protocols. Besides, it has quite a nice look and feel :-)
