How do you manage systemd-resolved?

Possible workarounds:

1. Disable LLMNR to let systemd-resolved immediately continue with appending the DNS suffixes.
2. Trim /etc/nsswitch.
3. Switch to using fully-qualified domain names.
4. Use /etc/hosts to resolve hostnames.
5. Fall back to using glibc’s dns instead of using systemd’s resolve.

How do I remove systemd-resolved?

How do I stop systemd resolve?

What’s the difference between systemd / resolve / stub.conf?

When using stub-resolv.conf, applications will make DNS requests to the DNS stub resolver provided by systemd on address 127.0.0.53. This stub resolver will proxy the DNS requests to the upstream DNS resolvers configured in systemd-resolved, applying whatever logic it wants to those requests and answers, like caching them.

Where is the DNS stub for systemd resolved?

· Additionally, systemd-resolved provides a local DNS stub listener on IP address 127.0.0.53 on the local loopback interface. Programs issuing DNS requests directly, bypassing any local API may be directed to this stub, in order to connect them to systemd-resolved.

How to use systemd-resolved.service in Ubuntu?

Note that /run/systemd/resolve/stub-resolv.conf should not be used directly by applications, but only through a symlink from /etc/resolv.conf. This file may be symlinked from /etc/resolv.conf in order to connect all local clients that bypass local DNS APIs to systemd-resolved with correct search domains settings.

What does systemd resolved do to a DNS server?

SIGUSR1 Upon reception of the SIGUSR1 process signal systemd-resolved will dump the contents of all DNS resource record caches it maintains, as well as all feature level information it learnt about configured DNS servers into the system logs.
