OpenSSH is the most popular version of the SSH protocol. In the process of researching this video today I kept coming across signs that some are confused by all the jargon. So I tried to boil it down and explain how SSH works, and what tools are available for ssh servers, ssh clients, a few of the ssh utilities, and finally even went into the application development side to explain what bindings are available in hopes more developers will begin adding SSH capabilities to their software (where is makes sense of course).
00:00 - Intro 00:24 - Title 00:31 - What is OpenSSH? 01:19 - History of SSH and OpenSSH 02:36 - What does OpenSSH do? 05:49 - SSH Protocols 12:22 - Other SSH Implementations 13:56 - SSH Client side products 18:10 - SSH Utilities 19:24 - Program Language Bindings 20:35 - OpenSSH things to be aware of 21:44 - Final Thoughts on OpenSSH 22:54 - Thanks
Today I am doing a bit of a reaction video to a statement made by one of the participants of a zoom conference hosted by the Linux Saloon about 3 weeks ago. I am not naming any names, nor do i mean this to be an attack against that person.
This video is meant to show how to evaluate a statement like that and determine if it is true or false. The comment (and I paraphrase) was "Do NOT use Debian it is not secure, the packages are old and out of date, use Ubuntu instead".
There is of course a couple of immediate red flags, first the statement is inflammatory, and does not succinctly describe the bounds of the statement, for example is this about the Workstation products or the Server products? Second what is the definition the person is using for secure.
I will be limiting my definition of secure by to what degree of hardening is applied to the system as a starting point. My plan is to make a 2nd part of this video and repeat the experiment for the Workstation versions of Ubuntu 22.04+ and Debian 11.5+.
I am hoping you will find this video as a possible method to use to evaluate different questions like this one, so we can arrive at a conclusion that is possible for you to reproduce.

How does Moore's Law stand up to the revision made in 1975, the disaster of the Tejas and Jawhawk project, the revision made in 2007, the stagnation of 2016 - 2020 and now that the chip manufactures are all pushing the Power and Heat Wall once again.
