Question: What Is 'SSH'?
You see this odd technical expression around the Net. Techie guys say "our network administrators use full SSH management techniques". But what exactly is 'SSH'?
Answer: SSH stands for "Secure Shell". SSH commonly uses port 22 to connect your computer to another computer on the Internet. It is most often used by network administrators as a remote login / remote control way to manage their business servers. Examples would be: your email administrator needs to reboot the company email server from his home, or your network administrator needs to reset your office password while she is away at a conference.

SSH strives to create confidential connections across the Net. With only a very few exceptions, it is not possible for a regular hacker to break into an SSH connection...the encryption technology is as reliable as 21st century programming can make it. SSH effectively locks out eavesdroppers by encrypting (ciphering) the connection, and scrambling the transmitted data so it is meaningless to anyone outside of the two computers involved.
