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.

Linux DNS settings is a total mess (lemdro.id)

I recently tried to enable system-wide DNS over https on Fedora. To do so I had to to some research and found out how comfusing it is for the average user (and even experienced users) to change the settings. In fact there are multiple backends messing with system DNS at the same time.

Most major Linux distributions use systemd-resolved for DNS but there is no utility for changing its configuration.

The average user would still try to change DNS settings by editing /etc/relov.conf (which is overwritten and will not survive reboots) or changing settings in Network Manager.

Based on documentation of systemd-resolved, the standard way of adding custom DNS servers is putting so-called 'drop-in' files in /etc/systemd/resolved.conf.d directory, especially when you want to use DNS-over-TLS or DNS-over-https.

Modern browsers use their buit-in DNS settings which adds to the confusion.

I think this is one area that Linux needs more work and more standardization.

How do you think it should be fixed?

Very much agreed 👍 I realized when using the dnscrypt to set the DNS settings. There is resolv.conf which used to be the final authority regarding your DNS. Now I don't know anymore

it still is, just make it read only.

not reliable, even if it should be. i've seen updates replace the file in a way that clears the read-only flag. same with other clever tricks like making it a symlink.

Yup. Tried that, doesn't work.
