What is SSH?
Simply SSH stands for Secured Shell. SSH is a network protocol which is used for sucure data communication.This protocol is used between two networked computers which are connected via a secure channel over an insecure network. Two computers are distinguish as client(runs SSH client) and server(runs SSH server).
History behind the SSH: Tatu Ylönen (Country:Finland) a researcher from Helsinki University of Technology designed the first version of SSH which is now called SSH-1.
SSH Features:
1) SSH is a Command line terminal connection tool.
2) SSH Replaces rsh, rcp, telnet, and others
3) All traffic encrypted in SSH protocol.
4) Both client and server side authenticate.
5) SSH is able to carry and encrypt non-terminal traffic.
SSH Installation in Ubuntu Environment: The Ubuntu flavour of SSH is called openSSH, which is a free open source SSH implementation.This SSH contains two components an openssh-client and an openssh-server. To check SSH in both client and server side below command can be used.
sudo apt-get install openssh-client openssh-server
