I am a little bit confused about the dns : I have systemd-resolved
installed and when I list the content of the package (rpm -ql), I can
read on the first line:
/etc/systemd/resolved.conf
But there is no /etc/systemd/resolved.conf
It's a ghost file. If it exists, it's owned by the package.
There is a /usr/lib/systemd/resolved.conf but it is a file the lines of
whitch are all commented...
That's the system default config which doesn't override any of the
program defaults.
There is a /usr/sbin/resolvconf and a man for this, so I tried to use
this resolvconf and read the man... Under the OPTIONS :
" -i INTERFACE, --interface=INTERFACE
Specifies the network interface to execute the query on.
This may either be specified as numeric interface index or as network
interface string (e.g.
"en0")"
So, I tried resolvconf -i eno1 and...
Switch -i not supported
lol!
I can see that /usr/sbin/resolvconf is a symbolic link to ../bin/resolvectl
Yes, if you notice, the man page is actually for "resolvectl" and if you
read to the bottom, you will get an answer to your "lol".
Trying to use resolvectl I get:
Global

resolv.conf mode: stub
Link 2 (eno1)

Well! But where is the config file where all this is defined? That's a
mystery!
It's using the defaults. Presumably your DHCP server is providing that
info or you've configured it in the network config.
It seems that (at least) two systems are install for the dns but is
there a way to see what is the one in use and how can I -- safely --
configure the dns system on my machine to use DNSOverTLS?
What two systems?
