Systemd: flushing the DNS cache	2022-07-04T17:22:48+02:00	2022-12-14T16:05:48+01:00	computerstuff	linux systemd networking manjaro dns

First off I want to say, that Systemd is quite new to me and I always used the old and classic init systems like OpenRC (which is still available on Gentoo -- if someone cares about that more than I do).

Now let's start right away, flushing the DNS cache on a linux box using Systemd is not that complicated, but the correct commands should be known.

And this post is all about that:

$ sudo systemd-resolve --flush-caches

You could also use sudo resolvectl flush-caches if you like or prefer.

Now verify the empty cache:

$ systemd-resolve --statistics

I usually do not need to flush my computers DNS caches, but fiddling with my firewall at home made me use this very often over the last few weeks.
