Can't enable unbound-control

[el_baby]

Hi,

since I didn't find a specific option in the unbound configuration, I added this under custom options:

remote-control:
        control-enable: yes
        control-interface: 127.0.0.1
        control-interface: ::1
        control-port: 8953

However, after restarting the service it still says that control-enable is 'no':

[2.7.2-RELEASE][admin@fw-ecuador-00.siu.edu.ar]/root: unbound-control stats_noreset
[1740747194] unbound-control[5960:0] warning: control-enable is 'no' in the config file.
[1740747194] unbound-control[5960:0] error: connect: Connection refused for 127.0.0.1 port 8953

What am I doing wrong?

Well... the resolver wasn't actually running because of a misconfiguration (though I couldn't see that in the GUI logs, I found out checking /var/log/system.log:

Feb 28 10:45:20 fw-ecuador-00 php-fpm[8951]: /services_unbound.php: The command '/usr/local/sbin/unbound -c /var/unbound/unbound.conf' returned exit code '1', the output was '[1740750320] unbound[68385:0] error: can't bind socket: Address already in use for 127.0.0.1 port 953 [1740750320] unbound[68385:0] error: cannot open control interface 127.0.0.1 953 [1740750320] unbound[68385:0] fatal error: could not open ports' 

Now... why would it try to open port 953 when I configured 8953?:

This :

@el_baby said in Can't enable unbound-control:

[2.7.2-RELEASE][admin@fw-ecuador-00.siu.edu.ar]/root: unbound-control stats_noreset

is not enough.
unbound-control with instructions, looks for the unbound control file here /usr/local/etc/unbound/unbound.conf
(go have a look - it isn't there, and if it does exists, that isn't the file actually used).

The unbound.conf file used by pfSense is here /var/unbound/unbound.conf
Ask pfSense ^^ :

[25.03-BETA][root@pfSense.bhf.tld]/root: ps aux | grep unbound
unbound 10684   0.8  4.9 223092 197948  -  Ss   Wed15     47:05.20 /usr/local/sbin/unbound -c /var/unbound/unbound.conf
......

also, is unbound listening on 8953 by default on local host ?

[25.03-BETA][root@pfSense.bhf.tld]/root: sockstat -4 | grep 'unbound'
unbound  unbound    10684 5   udp4   *:53                  *:*
unbound  unbound    10684 6   tcp4   *:53                  *:*
unbound  unbound    10684 7   tcp4   127.0.0.1:953         *:*
....

so it's port 953 (in my case).

Double check :
Cat /var/unbound/unbound.conf :
which tells you to look in /var/unbound/remotecontrol.conf
and there :

[25.03-BETA][root@pfSense.bhf.tld]/root: cat /var/unbound/remotecontrol.conf
remote-control:
        control-enable: yes
        control-interface: 127.0.0.1
        control-port: 953
        server-key-file: "/var/unbound/unbound_server.key"
        server-cert-file: "/var/unbound/unbound_server.pem"
        control-key-file: "/var/unbound/unbound_control.key"
        control-cert-file: "/var/unbound/unbound_control.pem"

Btw : Don't change these files yourself with a text editor. The pfSense recreates these files constantly, your edit will be gone in no time.

So, out of the box, this works :

unbound-control -c /var/unbound/unbound.conf stats_nores

Thanx a lot @Gertjan

That was it. It was listening on port 953.

Since I had not seen any configuration option in the UI I thought it was disabled.
