From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hi everyone! Can someone please walk me through changing dns on Fedora 38. I have pihole setup on my home server, but Fedora won’t use for the life of me. (It does work on my phone). Explain it like I’m 5, cos I’m losing my mind haha

Open the GUI network settings
Set DNS to the IP of the PiHole, make sure the "automatic" switch is off.
Do the above for each active interface (ethernet, wlan) and for both IPv4 and IPv6
Save/apply settings
Turn the interface(s) off, then back on
resolvectl flush-caches just in case

Look at resolvectl dns to check there's no DHCP-acquired DNS servers set anymore

If you use a VPN, those often set their own DNS servers too, remember to check it as well.

Thanks, I did that and so far so good. I did most of this before but it was reverting back to some other dns address and not working -_- now it works, so far

If its reverting, you may have a fallback DNS configured somewhere, or your browser is using DNS over HTTPS, which sometimes will bypass whatever DNS server you've configured.
