RHEL 10 must configure a DNS processing mode in Network Manager to avoid conflicts with other Domain Name Server (DNS) managers and to not leak DNS queries to untrusted networks.
Description
Discussion Text
To ensure that DNS resolver settings are respected, a DNS mode in Network Manager must be configured. The following are common DNS values in "NetworkManager.conf [main]":
- default: NetworkManager will update "/etc/resolv.conf" to reflect the nameservers provided by currently active connections.
- none: NetworkManager will not modify "/etc/resolv.conf". Used when DNS is managed manually or by another service.
- systemd-resolved: Uses "systemd-resolved" to manage DNS.
- dnsmasq: Enables the internal "dnsmasq" plugin.
