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:
|
|
|
|
|
|
|
|
|
|
~~~console
|
|
|
|
|
$ sudo systemd-resolve --flush-caches
|
|
|
|
|
~~~
|
|
|
|
|
|
|
|
|
|
You could also use `sudo resolvectl flush-caches` if you like or prefer.
|
|
|
|
|
|
|
|
|
|
Now verify the empty cache:
|
|
|
|
|
|
|
|
|
|
~~~console
|
|
|
|
|
$ 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.
