DNS Host Resolution Issues [SOLVED]

For some reason I'm having a lot of problems with my dns settings. I think it may be connected to my attempt at setting up protonvpn with qbittorrent yesterday. I don't have complete recollection but I probably ended up messing with my dns settings somehow. At first nothing was working, but after I edited /etc/resolv.conf to "nameserver 194.242.2.2" and /etc/systemd/resolved.conf to "DNS=194.242.2.2" (all other lines are commented out). Firefox stopped having issues. However, even with this solution Prism Launcher, a minecraft launcher, and pacman -Syu will not work. And in order for firefox to work, I have to reedit /etc/resolv.conf upon each boot (I'm aware this is intentional functionality). My firefox dns settings are set to max protection on custom, with https://doh.mullvad.net/dns-query as the custom dns (ips used for both conf files are mullvad dns). Other computers on the same network are functioning fine.

Re: DNS Host Resolution Issues [SOLVED]

dig @194.242.2.2 google.com
dig @1.1.1.1 google.com

194.242.2.2 is a mullvad server and will require that service to be properly configured and you logged in there and whatnot in order to give you a DNS
https://wiki.archlinux.org/title/Mullvad

Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Re: DNS Host Resolution Issues [SOLVED]

When I try to install bind (and any other package I'm met with this output:

$ sudo pacman -S bind
resolving dependencies...
looking for conflicting packages...

Packages (3) jemalloc-1:5.3.0-2  libmaxminddb-1.7.1-1  bind-9.18.17-1

Here's the output of the second command:

Forgot to mention this, but when I have firefox dns settings set to "Off: Use your default DNS resolver", any attempt to connect to a site gives me a typical server not found error.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at phoenixnap.com.

If you entered the right address, you can:

    Try again later
    Check your network connection
    Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Re: DNS Host Resolution Issues [SOLVED]

Download the bind package with another system, usb walk it to the problematic one and install it w/ "pacman -U"

You don't seem to have resolved enabled (not sure whether NM will just launch it by itself)

resolvectl status

Also post the contents of /etc/resolv.conf before editing it.

Lastly, the mullvad-daemon.service isn't enabled so I'd not expect their DNS to work for you?

Re: DNS Host Resolution Issues [SOLVED]

resolvectl status returns:

Failed to get global data: Unit dbus-org.freedesktop.resolve1.service not found.

and /etc/resolv.conf before editing looks like this:

Generated by NetworkManager

nameserver ::1

Also correct me if I'm wrong but I thought the mullvad-daemon service was only necessary to run mullvad vpn?

Haven't downloaded the bind package yet, will give update asap.

Re: DNS Host Resolution Issues [SOLVED]

You're not using resolved, editing /etc/systemd/resolved.conf is idempotent.
Change the NM settings and specify 1.1.1.1 as DNS server, you can also briefly manually edit etc/resolv.conf to that effect

nameserver 1.1.1.1

Should™ get you usable DNS (via cloudflares open DNS server), whether that's what you want is a different matter.

You can test

nmap -p 53 _gateway

on whether eg. your router has a DNS server (or stub) and otherwise might want to use resolved or a local dnsmasq instance.

Edit:

the mullvad-daemon service was only necessary to run mullvad vpn?

Yes, of course. But you were also trying to use their DNS…

Re: DNS Host Resolution Issues [SOLVED]

Was able to install bind locally by downloading from mirrors, had to grab some dependencies though.
