how to change DNS settings of my server ?
-
This doc seems to be for internal name resolution of my servers apps, like (app1.my-cloudron.com)
What I want is changing the DNS for external name resolution. For instance, instead of using google DNS 8.8.8.8 I want to use 9.9.9.9 -
no I'm using time4vps.
I tried edit the file
/etc/systemd/resolve.confwith this:[Resolve] DNS=9.9.9.9 9.9.9.10but it doesn't seem to work.
Is there something else I should do? I don't really understand the
unboundDNS configuration in this doc: https://docs.cloudron.io/networking/#dns -

I did restart systemd-resolved service but doesn't seem to work.
After doing so the content of/etc/resolv.confis :# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN # 127.0.0.53 is the systemd-resolved stub resolver. nameserver 212.24.109.143 nameserver 80.208.225.143Shouldn't it be 9.9.9.9 as specified in the

[Resolve] DNS=9.9.9.9 9.9.9.10Cloudron doc says
All apps and services use systemd-resolved for name resolution. You can configure systemctl-resolved as required by your network
So the above should have work isn't it ? -
I tried to changed the
/etc/unbound/unbound.conf.d/cloudron-network.confadding this:# Forward all DNS queries to Quad9 DNS forward-zone: name: "." forward-addr: 9.9.9.9 forward-addr: 149.112.112.112but request are still going to
212.24.109.143and not9.9.9.9what service is managing the /etc/resolve.conf file ?
here are all my files:

@cylon there's much to unwrap. Unfortunately, the way all these things interact is quite complicated.
Before I say anything, are you on Cloudron 8? I am wonder why you have your /etc/resolv.conf handled by resolvconf ? Cloudron 8 has removed this package. If you are still on some < v8, I recommend upgrading first because the instructions to change the DNS are different.
For Cloudron 8, here is a checklist:
- Make sure resolvconf package is not there . We don't install this anymore intentionally.
apt remove resolvconf /etc/resolv.confmust be a symlink to../run/systemd/resolve/stub-resolv.confsystemctl status systemd-resolvedmust be enabled- Finally,
/etc/systemd/resolved.confhas your preferred DNS servers (quad9 in your case).
That should be it. After that,
host www.cloudron.ioshould work out of the box. - Make sure resolvconf package is not there . We don't install this anymore intentionally.

I used to use Time4VPS and thoroughly enjoyed it. Did you check these out?:

I'm still indeed on v7, but I can't update to v8

@cylon for v7, cloudron uses unbound. For Cloudron 7, please check this:
/etc/resolv.confshould havenameserver 127.0.0.1systemctl status unboundshould say runninghost www.cloudron.io 127.0.0.1should work
systemd-resolvedis not used at all. So, you can ignore all those related threads and configs. I would like to understand how it got to this state though? Do you think it tried to upgrade to v8 and end it up in this state? -

That's possible, I don't remember if I first tried to upgrade to v8 or to change the DNS
I updated the
/etc/systemd/resolve.confand only after did I check the/etc/resolv/conffile, I don't know what state it was before I updated/etc/systemd/resolve.conf -
