By default, with
LLMNR=yes
set in/etc/systemd/resolved.conf
, here are the port bindings (usingnetstat -l -p -a -n
):tcp 0 0 0.0.0.0:5355 0.0.0.0:* LISTEN 8214/systemd-resolv tcp6 0 0 :::5355 :::* LISTEN 8214/systemd-resolv udp 0 0 0.0.0.0:5355 0.0.0.0:* 8214/systemd-resolv udp6 0 0 :::5355 :::* 8214/systemd-resolv
When
LLMNR=no
is set in/etc/systemd/resolved.conf
, I still have the following bindings:udp 0 0 0.0.0.0:5355 0.0.0.0:* 8214/systemd-resolv udp6 0 0 :::5355 :::* 8214/systemd-resolv
How can I completly unbound all LLMNR port bindings?
