SH SSH is a TCP/IP service that provides a secure mechanism for remotely logging into one system over either a local network or the internet into another system. SSH also provides the ability to transfer files between remote systems. When a user logs into a remote system using SSH, they receive a command prompt allowing them to enter commands on the remote system as if they were sitting at the remote system and had opened a terminal session.
In this chapter we will cover the steps necessary to configure an Ubuntu Linux system to accept SSH connections. This involves installing the SSH server on the local systems and configuring the firewall to allow SSH connections.
