How to enable IPv6 support on OMV6?

1st Official Post
    • Official Post

    ipv6 is enabled by default at the OS level. Some services managed by OMV will disable ipv6 support if ipv6 is not detected. If your network interface has an ipv6 address, it should just work. I used it for a long time until my ISP dropped support.

    I'm running into a similar issue. I cannot enable IPv6. When I attempt to switch and apply, I get the following error message and I am forced to undo the action. IPV6 is supported by my ISP. Maybe I'm missing something super obvious.

    Is this file installed by an omv-extra.org plugin?

    Nope.

    I would like to see what 20domains looks like if it exists.

    I don't know at all what 20domains is. My main issue is that I was getting IPV6 related connection issues. The OMV network page showing IPV6 disabled turned out to be a bit of a red herring. It turns out that I failed to create an AAAA IPV6 entry in my host record for my domains pointing to my local server. I created the records last night for all domains and it tested perfect this morning.


    However, attempting to enable IPV6 in the OMV gui still results in the error. My server is working with IPV6 now. Guess I'll ignore the error.

    ¯\_(ツ)_/¯

    What is the output of:

    ls -al /srv/salt/omv/deploy/hosts/

    cat /srv/salt/omv/deploy/hosts/20domains.sls

    Interesting. I investigated the entry in this file and noted that it is trying to append some custom hosts in a second hosts file in /etc. The /etc/hosts2 file exists but is empty. I removed the 20domains.sls file and tried once more to enable DHCP for IPV6 in the OMV dashboard. This time it succeeded! Though I wonder where this came from.


    The contents of the 20domains.sls file:


    Code
    {% set hosts = salt['cmd.shell']('cat /etc/hosts2') %} append_custom_hosts: file.append: - name:
"/etc/hosts"
- text: "{{ hosts }}"


    Output of ls -al /srv/salt/omv/deploy/hosts/

    Code

    This jogged my memory. A long while back I recall learning and dealing with some issues pertaining to the inability to edit /etc/hosts in OMV as it is controlled by OMV. I ran across this blog where a user claimed to have crafted a workaround. Apparently it didn't work or no longer works or something. I was a little careless on this and didn't document what I did for future me to know what the heck past me did.

    That explains more. I would delete that file.

    Here is what votdev told me.

    RE: Proper way to add entry to /etc/hosts
    You need to use a custom Salt state to do not loose your changes when OMV rebuilds the file.

    Check
    votdev


    Maybe there could be an "Extra Options" or something?

    You know my opinion about adding any input fields to give users any tuning options. Those are only added if they make sense for all users, they fit into the OMV concept and do not complicate the administration & configuration experience.

    With openmediavault 6.4.0 i hope that many networking issues will be fixed because some things were misconfigured in older versions. With the fixes done in 6.4.0 systemd-resolved is correctly used.

    For reference, here's what my system shows (IPv6 enabled and working)
