What you will learn

Use client and server configuration files to cutomize SSH to your very needs

Securely trasnfer files and directories over the network using the secure shell

Enhance authentication security by enforcing public/private key authentication

Run GUI applications over the network through SSH X11 forwarding

Bypass local and remote firewalls using SSH tunnels

Create your own SOCKS5 proxy using only SSH


Description

Whether you are a UNIX/Linux administrator, a casual user, a macOS owner, or even a Microsoft Windows user, you've probably used SSH (secure shell) in some way or another. This course is going to uncover some of the less-known features of SSH. Yes, it will teach SSH for the total beginner, but it will also show SSH veterans some tips and tricks that perhaps they don't know they ever existed.

I tried to make this class as modular as possible. This means that you could skip lectures whose topics you already know, and watch only what want to gain knowledge about. You can view the lectures in any order you want because they are largely non-dependent on each other.

Have a quick look at the lecture titles, watch the free preview and enroll now to become an SSH wizard!

This is a great ssh course. Topics are explained clearly and they are supported with practical examples. You'll need some command line knowledge, though. While ssh commands are explained in detail, other Linux CLI commands are not and things are happening pretty fast - make sure you can follow along.
