If you use Linux your kernel is more than likely 5.xx unless you’ve changed
Yup, mine’s 5.4.0-42
Running Kubuntu 20.04
Only port open is for the web and I have my firewall set up as per recommendations from Ubuntu.org.
I don’t even know how one would go about setting up sudo to be used by anyone but it’s not set up that way with a standard install. I have to give a password anytime I use it to update, install or work on a protected file etc, as is standard.
Love Linux. Boot time is about 15 seconds on my dual boot windows/linux system and shut down time for Linux is less than 5 seconds. That’s running Plasma desktop which is one of the heavier ones and running an 8 year old Thinkpad. I can shut down 3 browsers, two email clients and a couple of other programs and still, less than 5 second shutdown time. Try that on windows. Walked by my son yesterday and glanced at his windows 10 shutting down and doing an update. 10 minutes or so. I’m updating as I type and will not have to do a restart. I haven’t paid for an operating system or program for well over 15 years.
Update is done:)
