Jay your videos are very well done. The production is getting better with each video. Thank you so much for the tutoring. Also looking forward to the arrival of your 3rd edition. Keep up the great work.

[_Fortress_]

Great video! I really appreciate you taking the time to put together a guide like this. Would love to see you talk about how you manage/backup keys as well.

Hands down the best ssh walk through I've watched, finally I get it. Thanks!

[heikokraemer]

This was the second ssh tutorial I've taken on YouTube … now I know where I'll look first next time.
Thanks for this great session and for covering the security and troubleshooting essentials!

Jay, you’re a gem of an educator and I really appreciate the channel you’ve built and all the hard work you’ve done. Thank you.

[joshmcneil]

Thank you Jay. I've been using your videos for nearly a year now and I can honestly say that I have grown quite a lot, and much of that is attributable to you and your content. I am very much grateful for your time and tutelage. It has been integral to my learning. I'll be taking the RHSCA soon, and I will be remain a life-time viewer of the channel. All the best to you and yours.

Your videos always take me to the next level. I have been using ssh to access my pi's using keys but now I will harden them by moving away from blank keyphrases and definitely removing password authentication. Thanks for giving me such great perspective!

[GustavAgar]

This tutorial of SSH is simply the best one on whole internet. I also recommend the 5 tweaks to secure openssh from the same channel

I understood the inner workings of SSH more after this 90 minute video than I have over six months of Linux usage. Thanks, Jay.

[seanacus]

This was a great tutorial. Please keep making more of these. Thank you for taking the time.

Honestly, I don't know how can somebody dislike this video, it is a very clear, amazing explanation, all I needed.

[sathishkumarshanmugavel]

Thank you for this guide. you have covered all aspects of the tool including troubleshooting. Your lecture is clear and easy to follow. Audio and video qualities are excellent and particularly the bigger fonts on your terminal 🙂. I have been using ssh for several years but now I have clear picture of the tool.

[BokanoiD]

You'd make an excellent teacher. This is the clearest way I've seen anyone explain anything in a while. Well done.

[annihilatorg]

Thank you for this, Jay. I really appreciated your additional info such as the troubleshooting steps and watching the appropriate logs. I would have also appreciated a backup/restore section for the ssh keys. While it's as simple as backing up and restoring the appropriate private/public key pairs, I'd have appreciated having that step included.

[MarkusEicher]

Hi Jay, hello community. Thanks for this basic intro. Coming from a Windows world now embracing Linux and learning to manage it. These kinds of basics are boring for Linux gurus, but essential for newbies like me. Good to have you and your channel as a mentor. I appreciate your work. 🤛

[GeorgeMulak]

This is the first time I feel like I am understanding this SSH topic. You have a gift of teaching. Please consider hacking out the rest of this topic, if you have not already. Thank you.

[bonfireatnight]

Wow, this was a great video! The explanations are perfectly clear and it provides just the right amount of information to become somewhat competent without getting overwhelmed. Thanks!

[mickymcl]

As a complete novice I even surprised myself, by being able to follow most of what you taught first time, need a few more watches to get it all to sit. Thanks a lot for clear explanations and the great examples.

[Appalling]

Hi Jay. I am SO GLAD I stumbled upon this video (two years later). Thank you SO MUCH!
