Chapter 2. Basic Client Use
SSH is a simple idea but it has many parts, some of them complex. This chapter is designed to get you started with SSH quickly. We cover the basics of SSH’s most immediately useful features:
Logging into a remote computer over a secure connection
Transferring files between computers over a secure connection
We also introduce authentication with cryptographic keys, a more secure alternative to ordinary passwords. Advanced uses of client programs, such as multiple keys, client configuration files, and TCP port forwarding, are covered in later chapters. Our examples in this chapter work with OpenSSH and Tectia on Linux and other Unix-inspired operating systems.
