NetworkManager and systemd-networkd/systemd-resolved
Hello,
on my notebook computer, I have a WLAN interface that is managed with
NetworkManager and a cable-bound network interface that gets its static
IP address by a systemd-networkd configuration file. But as of course on
a portable notebook the cable-bound network interface is not always
connected, it is a additionally also managed by NetworkManager. Hostname
resolution takes place through systemd-resolved, that is,
/etc/resolv.conf is a symbolic link to
/run/systemd/resolve/stub-resolv.conf .
This all works fine so far, but when the cable-bound interface is not
connected (that means, when NetworkManager de-activated the connection),
the nameservers defined for that connection in the systemd-networkd
configuration file are still in the active systemd-resolved
configuration, as can be seen in the file
/run/systemd/resolve/resolv.conf and in the output of "resolvectl
status". Though this is - at least in my case with maximum of three
nameservers - only a cosmetic problem, my goal is that the nameservers
defined for the cable-bound connection disappear from the active
systemd-resolved configuration when the cable is disconnected.
Is it possible to realize such a combination of NetworkManager and
systemd-networkd/systemd-resolved?
Regards
Christoph
