This workshop is intended for novices who want to improve their practical knowledge and experience with OpenSSH.
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.
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.

Recently, he presented his work on SSL/TLS toolkits at Nullcon 2025 in Goa. He contributed to the cleanup and enhancement efforts done on ssldump lately. He particularly enjoys tinkering with open (and not so open) hardware. Currently he likes playing around with new tools in the current ML scene, building, hopefully, useful systems for fun and, maybe, profit.
