99% of your userbase will be covered by this. This configures resolved, which is the DNS daemon on almost all Linux distributions. You should be able to use the tool resolvectl. It doesn’t always achieve what you want and when it does, it creates a broken system. VPN clients should not be able to change /etc/nf.

As a final example, some third party applications on fedora still use /etc/nf, so depending on the application, it will have different behavior.Īs a user, I think made the right decision here.

Another example: if the user is working with a local Kubernetes cluster, DNS integration with their desktop will stop working.

To the user, it will seem as if they can still modify their DNS settings, but none of the modifications will actually change anything.

For example, all GUI and CLI interfaces to change DNS settings will silently fail.

It will cause a bunch of weird to debug issues. It completely bypasses the “regular” DNS infrastructure of the host machine and will make a lot of users and OS developers annoyed. It’s akin to throwing a brick through a window in order to get some fresh air. That means any script or program that writes to /etc/nf is probably broken.Īpart from the fact that it won’t work, it’s also a user-hostile solution. Importantly, when nss-resolve is used, glibc does not read /etc/nf when performing name resolution, so any configuration that you put there is totally ignored. See Understanding systemd-resolved, Split DNS, and VPN Configuration for more information on how modern DNS resolution works. Even changing /etc/nf is not a universal solution, as it will not work on Fedora anymore, for example. However, I do have some experience with vpn clients so I can offer some info on there any universal solution to changing DNS settings on the host machine? Probably, I miss some snap interface.Įasy-openvpn-server is a vpn server, not a client, so it doesn’t need to change DNS settings on the host machine. systemd-resolve dns -interface=wlp3s0 -set-dns=1.1.1.1).īut, unfortunately, it is not accessible from strict confinement (no permissions). The way which have effect is to use systemd-resolve (e.g.

echo 9.9.9.9 | resolvconf -a wlp3s0).Īnd sometimes it returns an error: run-parts: /etc/resolvconf/update.d/libc exited with return code 1. Unfortunately, usage of resolvconf does not take effect on the host system (e.g. It means, again, the application needs access to /etc/nf to configure it properly (to create a symlink to a correct file).Īnyway, I was tried the resolvconf with properly configured systemd-resolved on the host machine: So, any manipulations with resolvconf/systemd-resolve/resolvectl do not have an effect.

On my machine, for example, it points to /run/resolvconf/nf.

The systemd-resolved functionality does not work when /etc/nf linked to something else than /run/systemd/resolve/nf. I have doubts that using resolvconf approach will work on every user’s machine: I don’t see here the danger to harm user configuration. It just makes a backup copy of /etc/nf (in your case, it is a link to /run/systemd/resolve/nf) and replaces it on the configuration required for the current VPN connection.Īfter the VPN disconnects - the daemon restores the previous configuration.Īdditionally, the OS is overwriting this file with the original data on every reboot. Thanks in application do not change /run/systemd/resolve/nf at all. I kindly ask you to approve the package and allow auto-connect for the interfaces: system-files, network-control, firewall-control.

The interfaces above are critical for our software to work properly. firewall-control - IVPN client needs to control firewall rules (iptables) to avoid any potential IP leaks.network-control - ability to establish VPN connections and monitor network settings/chnages.system-files - (for /etc/nf and /etc/) we have to control global DNS configuration when VPN is connected (and we have to keep and restore original DNS settings when VPN disconnected ).Interfaces explanation (needed for the daemon part of the package): The software I want to publish is an open-source VPN client
