DNS controller?

  • Yes it's started:

    But DNS queries uses the DNS server specified in : /etc/resolv.conf (which is in my case) instead of the server I had configured with OMV web GUI ( :

    I'm not sure but it seems that there's no symlink for /etc/resolv.conf. Do you know how to check this exactly? I've tried this and it doesn't output the file we're looking for:

  • It seems it's not a symlink:

    root@openmediavault:/etc# readlink -f resolv.conf



    And it seems that /run/systemd/resolved/resolv.conf doesn't exist... :

    root@openmediavault:/# cd /run/systemd/resolved/

    -bash: cd: /run/systemd/resolved/: No such file or directory


    Do you have an idea of what's going on?

  • I had a typo in my /run path. I corrected the post but it should be: /run/systemd/resolve/resolv.conf

    What is the output of (cut&paste works): ls -al /run/systemd/resolve/resolv.conf

    If it is there, I would:

    sudo rm /etc/resolv.conf && sudo ln -s /run/systemd/resolve/resolv.conf /etc/

    omv 5.5.12 usul | 64 bit | 5.4 proxmox kernel | omvextrasorg 5.4.2
    omv-extras.org plugins source code and issue tracker - github

    Please don't PM for support... Too many PMs!

  • Yes it exists:

    root@openmediavault:~# ls -al /run/systemd/resolve/resolv.conf

    -rw-r--r-- 1 systemd-resolve systemd-resolve 637 Jun 18 12:59 /run/systemd/resolve/resolv.conf

    Content of /run/systemd/resolve/resolv.conf:




    search local

    Deleted /etc/resolv.conf and re-created it as a symlink:

    root@openmediavault:/etc#sudo rm /etc/resolv.conf && sudo ln -s /run/systemd/resolve/resolv.conf /etc/

    Now we can see that resolv.conf is a symlink within the /etc/ folder:

    root@openmediavault:/etc# ls -la /etc/ | grep "\->"

    lrwxrwxrwx 1 root root 35 Jun 16 19:51 localtime -> /usr/share/zoneinfo/America/Moncton

    lrwxrwxrwx 1 root root 19 Jun 16 17:43 mtab -> ../proc/self/mounts

    lrwxrwxrwx 1 root root 21 May 2 16:39 os-release -> ../usr/lib/os-release

    lrwxrwxrwx 1 root root 32 Jun 18 13:14 resolv.conf -> /run/systemd/resolve/resolv.conf

    lrwxrwxrwx 1 root root 13 Jun 16 17:27 rmt -> /usr/sbin/rmt

    Checked content: It was empty...

    sudo nano /etc/resolv.conf

    Restarted systemd-resolved:

    systemctl restart systemd-resolved

    Checked content:

    sudo nano /etc/resolv.conf

    Now the content is:


    The name server I had set using omv-firstaid!!! :)

    Did reboot OMV to make sure everything stays as it is.

    Checked which DSN server was used using dig:

    root@openmediavault:~# dig twitter.com

    ; <<>> DiG 9.11.5-P4-5.1+deb10u1-Debian <<>> twitter.com

    ;; global options: +cmd

    ;; Got answer:

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6226

    ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1


    ; EDNS: version: 0, flags:; udp: 512


    ;twitter.com. IN A


    twitter.com. 391 IN A

    twitter.com. 391 IN A

    ;; Query time: 60 msec

    ;; SERVER:

    ;; WHEN: Thu Jun 18 13:43:59 UTC 2020

    ;; MSG SIZE rcvd: 72

    It's . So it stayed the same.

    Let's do another check:

    root@openmediavault:~# resolvectl status


    LLMNR setting: yes

    MulticastDNS setting: yes

    DNSOverTLS setting: no

    DNSSEC setting: allow-downgrade

    DNSSEC supported: yes

    DNSSEC NTA: 10.in-addr.arpa






    Link 2 (ens33)

    Current Scopes: DNS LLMNR/IPv4

    DefaultRoute setting: yes

    LLMNR setting: yes

    MulticastDNS setting: no

    DNSOverTLS setting: no

    DNSSEC setting: allow-downgrade

    DNSSEC supported: yes

    Current DNS Server:

    DNS Servers:

    Now it seems that the Global DNS isn't used. It's the Link 2 DNS that is used.


    Thanks a lot ryecoaaron!! (I did send you a PM would you please check it?)
