when changing the ssh port number just be careful to not lock yourself by ufw (enable that port before changing the sshd config file)

I realize this video is dated however, I'm just starting to learn about home labbing and this was a great video, with a great instructor! I learned things! ...and took notes.
One thing I want to do is provide movie streaming for my disabled neighbor who is on a low fixed income with stage 4 RA to be able to have a way to watch movies, especially over the long winter months. This is going to require my eventual media server to be accessible off premises.
I've acquired a HUGE assortment of dvd's from a pawn shop that closed down.
Security is going to be a must.

Quick tip make sure before switching your port to allow the port. I ran into an issue where my firewall was blocking my assigned port number. Use this command to allow/enable it - sudo ufw allow PORT_NUMBER

Internet: adoption of IPv6 goes too slow
Tony: disable IPv6

You should display commands in yellow and bold it will be helpful

How likely is it to be attacked if the server is managing your local network on a private ip network?

[doughayden]

YOU ARE GREAT! I have spent $$$$ on upwork consultants but I learn more from your videos. I would gladly send you $$ if you tell me how

[arkofimagination]

I use SSH directly from my GCP. Should I still SSH keys, not password?

[WHAT-GRINDS-MY-GEARS]

Good stuff. What do you think about the project on github?

[EdwinMartin]

“SSH port is 22 and every hacker knows this”.
Oh, shit! 😱

Hey can I use contabo vps for live streaming 24/7 does they provide streaming service

[YukiNakaii]

should someone using a desktop still use SSH, or are all of those steps primarily for ppl using servers remotely? thanks in advance

[TLOZ]

If you want secure Linux Distro pls install Debial or Arch 😅

[david_osipov]

Disabling IPv6 for security? That's a bs

[ilyaaztiki]

liveoverflow debunked most of these tips

This man is not a specialist he obviously gets all his information off google and has no real insight on the cybersecurity field.
