Original Pull Request: https://github.com/netbirdio/netbird/pull/1493

State: closed
Merged: Yes

Describe your changes

In the case of disabled stub listener the list of name servers is unordered. The solution is to configure the resolv.conf file directly instead of dbus API.
Because third-party services also can manipulate the DNS settings the agent watch the resolv.conf file and keep it up to date.

apply file type DNS manager if in the name server list does not exist the 127.0.0.53 address
watching the resolv.conf file with inotify service and overwrite all the time if the configuration has changed and it invalid
fix resolv.conf generation algorithm

Issue ticket number and link

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
