SSH Series

SSH (Secure Shell) is a cryptographic network protocol used for secure communication between a client and a remote server. It is the standard way to log into remote Linux machines, transfer files, and create encrypted tunnels.

This series covers everything you need to work with SSH, from basic connections to advanced techniques like tunneling and chroot jails.

You can also use the SSH cheatsheet as a quick reference while reading the series.

What You’ll Learn

  • Getting Started — The SSH command, enabling SSH on different systems, configuring the client, and changing the default port
  • Key-Based Authentication — Generating SSH keys on Linux and Windows, setting up keys on various distributions, and configuring passwordless login
  • Tunneling & Port Forwarding — Local and remote port forwarding, dynamic tunneling, and SOCKS proxies for private browsing
  • File Transfer — Copying files with SCP and SFTP, changing the SFTP port, setting up chroot jails, mounting remote directories with SSHFS, and using Rsync over SSH

Prerequisites

  • Access to a Linux, macOS, or Windows terminal
  • A remote server or virtual machine to connect to
  • Basic familiarity with the Linux command line

Each article includes step-by-step instructions and practical examples. By the end of this series, you will be able to securely manage remote servers, automate authentication with SSH keys, and transfer files over encrypted connections.
