15.6 Secure Shell (SSH) Public Key Authentication
This section covers the generation of public and private keys in a Linux and Windows
environment and configuring SSH for public key authentication. The steps to use in a Clustering
environment are:

Generate a new public and private key pair

Upload the keys to the Master and to each Slave Console Server
-
Fingerprint each connection to validate
15.6.1 SSH Overview
Popular TCP/IP applications such as Telnet, rlogin, ftp, and others transmit their passwords
unencrypted. Doing this across public networks like the Internet can have catastrophic
consequences. It leaves the door open for eavesdropping, connection hijacking, and other
network-level attacks.
Secure Shell (SSH) is a program to log into another computer over a network, to execute
commands in a remote machine, and to move files from one machine to another. It provides
strong authentication and secure communications over unsecure channels.
