Configuring is VERY important, otherwise your could get locked out to the Internet! Also need ssh Enabled. You would have to go to the Servers Terminal to correct this!
i tried setting up ufw on my laptop but even with ssh allowed i can't connect to ssh. ssh only works with ufw disabled. why? on arch edit: seems kde's settings was allowing from 22 to anywhere instead of from anywhere to 22, manually setting it up fixed it
Hi there. The problem I'm getting is (I'm running Kali Linux in a Virtual Machine): Once I configure the UFW and I run the command "ufw status" it says "port xx deny" but if I use the NMAP it says "port open". Do you know what could be? Thnak you!
If you're checking with Nmap locally then it may be using the loopback interface which has separate rules in UFW. You can change how UFW handles loopback connections in the /etc/ufw/before.rules file. If you're testing from another server, then you may want to try setting up UFW again to make sure everything's configured as you expect. If you're scanning over IPv6, make sure that IPV6=yes is included in /etc/default/ufw so that it handles IPv6 traffic as well.
Hi, thank you for all the videos you make ! I do have an issue though, I have a contact form that sends messages to the gmail smtp server, but it doesn't work (but works on development and on PythonAnywhere). I would like to know how I could achieve the same thing on my Linode. I think this is related with the UFW, but I can't be 100% sure. Anyway, thank you for your help!

All of this information is really nice but I'm having a real interesting problem no granite I'm just trying to figure out Lennox button when I open terminal and put something in and push enter it says enter password but it will not let me enter Anything push button to keys and nothing what the hell am I doing wrong
Why everybody think that if you are using a firewall in Linux then you must be using it in your server and not in your desktop??!! Not everybody running a server at home or using a VPS or they have a linode server!!! Why people can't think that there are a lot of SIMPLE people like me who use Linux as their daily drive??!!
@@ofchaot Because they post videos where they assume that Linux and firewall means you are running a server. You might know that a Server environment is a lot different than a Desktop environment and those who are new to Linux and use it in desktops cannot relate. If you are making a video tutorial then you should name it in a way that the viewer can understand for whom the video is made so that their time would not be a waste. I think you would understand by now. 🙂
Typical Linux, each and every tutorial always starts out with something crazy simple that does not work when you reproduce it, each and every time. " Connection refused".
crisp and clear. Thanks Jay LaCroix
thank you so much for these videos. very practical, very informative.
Thank you so much, hopefully you make an updated 2021 compilation video for hardened security settings in linux
I am a beginner, this was valuable information.
Clearly explain. Thanks for the great explanation and sharing. Have a nice day ahead!
Thanks as always Jay! Awesome video.
Thank you! Linode customer for about 2 years now.
Just a heads up you still leaked your public ip in the video, i am kinda late seeing this video but still.
Thank You So Much You Made It So Easy And Clear 💓

when you allow ssh from your dynamic public ip, how can you prevent not being locked out from your own server?

Hi Jay,
Out of scope of this video, just wondering if could post series dedicated to DNS?
lost at the start how do you create linodes for UFW ?
Nice and clear. grettings :)
is it possible for you to make a tutorial about port forwarding with ufw ?
Is portmaster is the better firewall than firewalld and ufw/gufw
Thanks , it was very useful.
How can I configure ufw for just one specific interface?

Why do you care? Dont care what other people think

have you checked iodéOS firewall?
Hi . very useful. thanks
gREAT work Thank you
need a geo blocking video!...id like to block some countries
Thank you!
Thank you.
too bad we can't use dns instead of ip to white list our ssh. that would make things better
