Secure Linux & protect servers from Hackers with Fail2Ban

[@JosephBenson]

Wow this is what I have been looking for, for years now. Thank you 🎉😂😊 I want to say God bless you, you really safe me from hackers now.

[@thekrobar]

Awesome stuff! Your explanation of fail2ban was great! I got my VPS secured now

[@DigitalIndependent]

Glad it helped! Fail2ban can be a bit tricky… Try the ssh keys if you haven’t tried them yet :) And lots of fun with your VPS!

[@massgrave8x]

this is my go-to resource for hardening ubuntu server instances. thank you for these clear and concise explanations.

[@DigitalIndependent]

Thanks! Happy to help! Do try using ssh keys also :)

[@jimcabezola3051]

I really like your CLEAR explanation of fail2ban. I feel more confident to do this on my Debian 12 laptop and this Mint 21.1 Mac Mini.

[@DigitalIndependent]

Thanks :) Fail2ban can be a bit intimidating, but it’s a great tool. Hope you have lots of fun with it and block all the bad stuff out there :)

@@DigitalIndependent Tinkering in Linux gives me a sense of control over things in my life. In a world spinning out of control, Linux is a help to me. Having JUST installed it less than an hour ago on both Mint 21.1 and Debian 12, i found my first surprise that "whois" was NOT a standard part of MY Linux distros. That was on the distros at work, but not at home. Hmmm...fascinating. I will ENJOY tinkering with this. Mahalo!

Bitteschön! Freut mich zu lesen. Der Akzent sollte aber nicht so deutlich sein :)

[@jim6477]

Great video, thanks!

[@DigitalIndependent]

Thanks! Glad I could help :)

[@Jamxknife]

Thanks been looking for something like this

[@lordquadrato437]

sudo ufw status just yielded "Status: inactive", and when I enabled it, the status still didn't display any ALLOW ports. I don't know if I doged a bullet because I was still connected, but I quickly added port 22. Mighty be good to keep in mind to check that first.

[@sudtheshawty]

will you continue to make more videos?

[@DigitalIndependent]

I had a video done and ready on your personal VPN. But the maintainer noped out, killing my video. Redid it, it’s in post production.

[@takennmc]

btw when you edit sshd config you should restart sshd with systemctl restart sshd so the new config applies as you may run the server without reboot for a while and have the bad setting

[@DigitalIndependent]

Thanks for pointing that out!

[@javabeanz8549]

While yes, they do attempt to ssh in as root, I just looked at 1000 lines of failed ssh logins, less than a dozen were for root, the rest were invalid users. They try just about anything.

[@iamrage4753]

Crowdsec?

[@DigitalIndependent]

Yes. A good option. But sometimes a bit tricky for absolute beginners…
