A small clarification I'd recommend for this video is you don't put in firewall rules to connect out, only if you want to allow things to connect in. SSH doesn't need a rule on your workstation to connect to a remote server, but the server would need a rule to allow a connection, while Transmission would need a rule on your workstation for torrent peers to download your seeded torrents. Missing that distinction can be confusing if you're not familiar with firewalls.

Thanks, with all the hightened cyberattck awareness of late I was just thinking of this!

[aussierule]

Thank you very much! I'm one of those people who asked and I was shocked and surprised when I saw this video come up. So awesome dude, you rock!

[CyperN]

That's what I like about you videos Matt, you provide the important things in a easy way to understand.

[antoinestevan]

Things have been asked. Answers have been given back.
Really great job, thanks a lot!

[supergrafxengine]

Thank you! you go straight to the point plus extra informations ! Great man indeed

[fecklesstech]

Perfect demo Matt. You have a knack for posting videos about the exact thing I happen to be thinking about. Weird I know. Good timing? Telepathy? Whatever--thanks.

[OcteractSG]

Thanks for the intro. I’d definitely want to look at allowing traffic from only specific IP addresses and specify ports in place of applications.

[ClarenceNickels]

Great job Mat I really appreciate your explanations, thanks and keep up the good work!

Hello, I'm also also interested in more education videos. Such as how linux file system works .etc more towards deeper level into linux

[walter_lesaulnier]

I LOVE Fedora, but the firewall that comes with it is an unholy complicated nightmare designed for IT professionals in Enterprise situations.

@TLC maybe you can do some tutorials about pfsense? I know that on net are many tuts about that but you very clearly talking about things and this can be good series for your viewers including me ;) thank you!

As a normal user who only uses Firefox, I don't have a server. Do I really need to enable SSH for income connection?

Gufw, ufw it's so old! after install just one click and done. in terminal you are typing just to hear the knocking buttons?

[roberttranceedm]

Rather use nftables and firewalld (and gui for, which is easily available and blatantly called Firewall).
Better solution, newer, replacement for iptables.

[lazynoob]

Sudo apt install gufw
Sudo pacman -S gufw

Enable and you are done

[SkyFly]

I believe Linux also needs a real time anti malware and virus app against real time attacks and threats.

[andreaspriantono]

Somehow, gufw is not simple at all for me.... ufw is better...
