*I haven't ever gotten dnssec-trigger to work, but today based on IRC
|
|
discussion, I finally understood what was wrong.*
|
|
|
|
It's very simple.
|
|
|
|
```
|
|
# Check for updates to the repos & install dnssec-trigger and unbound
|
|
sudo apt-get update && sudo apt-get install unbound dnssec-trigger
|
|
```
|
|
|
|
And this is the farthest I have gotten before. But today at IRC there
|
|
was talk on DNS proxies which Ubuntu and Fedora use, Ubuntu uses dnsmasq
|
|
and Fedora unbound. That made me *read the fine manual* of
|
|
NetworkManager.conf...
|
|
|
|
|
|
```man
|
|
dns
|
|
Set the DNS (resolv.conf) processing mode.
|
|
|
|
default: The default if the key is not specified. NetworkManager
|
|
will update resolv.conf to reflect the nameservers provided by
|
|
currently active connections.
|
|
|
|
dnsmasq: NetworkManager will run dnsmasq as a local caching
|
|
nameserver, using a "split DNS" configuration if you are connected
|
|
to a VPN, and then update resolv.conf to point to the local
|
|
nameserver.
|
|
|
|
unbound: NetworkManager will talk to unbound and dnssec-triggerd,
|
|
providing a "split DNS" configuration with DNSSEC support. The
|
|
/etc/resolv.conf will be managed by dnssec-trigger daemon.
|
|
|
|
none: NetworkManager will not modify resolv.conf.
|
|
```
|
|
|
|
And there is the solution, unbound. The third line of NetworkManager.conf
|
|
is usually `dns=dnsmasq`, just change it to `dns=unbound` or add the line
|
|
if it doesn't exist and restart networkmanager with `sudo systemctl restart NetworkManager.service` and your dnssec-trigger should now work.
|
|
|
|
And when you `sudo reboot` you should see new dnssec-trigger tray icon in
|
|
your tray bar or whatever it was called as.
|
|
|
|
*Edit*: Arch users do remember do `systemctl enable dnssec-triggerd` and
|
|
`systemctl enable unbound`.
