15.6 Secure Shell (SSH) Public Key Authentication
This section covers how to generate public and private keys in a Linux and Windows environment and configure 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 pubic 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 insecure channels.
