Chapter 3. Communicating Between Nodes via SSH

SSH is one of the most important tools for a Linux network administrator. It allows you to connect to servers and other workstations remotely, and work on them from within your favorite terminal emulator—all from the comfort of your desk. While SSH might not be the perfect tool for every situation, it's one of those that you won't be able to imagine life without, once you start using it.

In this chapter, we explore SSH and cover the following topics:

  • Using OpenSSH

  • Installing and configuring OpenSSH

  • Connecting to network hosts via openssh-client

  • The OpenSSH config file

  • Understanding and utilizing scp

  • Transferring files to another node via scp

  • Tunneling traffic via SSH

  • Generating public keys

  • Keeping SSH connections alive

  • Exploring an alternative to SSH – utilizing Mosh (mobile shell)
