During this workshop, you will learn how to use the various tools from the
OpenSSH suite. We will start with a presentation of the problems that are solved
by OpenSSH, then we will dive into the details of its most important and useful
features.
Among the topics covered, we will discuss about remote host authentication,
password and public key client authentication, key generation, local and remote
port forwarding, forward and reverse SOCKS proxying, X11 forwarding, jumphosts, connection to legacy systems, and more.
Hands-on exercises will be proposed throughout the exploration of the tool suite
using real-life scenarios. There will be space for questions and discussion.
This workshop is intended for beginners who wants to improve their practical
knowledge and experience with OpenSSH.
Basic networking and Linux shell knowledge are required in order to follow this
workshop. Each participant will need a Linux machine (on which they have root access) with Docker pre-installed and Internet access.
Most beginners only use the ssh command from OpenSSH to reach a shell on
remote machines, and that's it. They don't really know how to deal with
features like port forwarding in order to ease their work.
This workshop is designed to help them level up their skills with OpenSSH.
