How to use SSH/Shell Access

Secure Shell or SSH allows users to exchange information through a secure channel. It is used mostly on an operating system that is based on Linux and Unix. SSH was developed to replace other insecure remote shells. SSH uses a secure encryption to ensure that your data is safe over an insecure network.

SSH uses a public key to encrypt the remote computer. SSH is usually used to login to a remote machine to carry out commands. Some of the features that SSH supports include tunneling, forwarding TCP ports and X11 connections.  The SSH client program is utilized to connect to an SSH daemon. The SSH client program and SSH daemon are available in operating system such as, Mac OS X, Linus, Open VMS and Solaris.

SSH was originally developed by a Finnish researcher called Tatu Ylonen at Helsinki Universy of Technology in 1995. The initial version of SSH is called SSH-1. SSH-1 was devekiped to replace TELNET and rsh protocols which did not provide secure encryption of the data. SSH-1 was first released as a freeware and many people start using it in a short time. At the end of 1995, there are already 20,000 users in 50 countries.
