Invalid unbound.conf / syntax error when attempting to override host via includ

  • Hi there.

    It's taken quite some work, but i've gotten as far as i can.  I'm stuck!  Please help!  I am trying to create list of hosts that i'd like to block at the DNS layer.  I know that i can use the pfSense webUI to just add a host or domain override, but i want to do this in an automatic way and at scale.  Basically, i want to implement my own version of this block list:

    So, now it should be clear what i'm trying to do.

    Here's what I have done so far:

    • Via the webUI, i have added a directive to include my own config file.
    include: /var/unbound/my_blocks.conf
    • Via the webUI, i have added a host override for in order to route all DNS queries for this example host to a loopback.  The last line of my host_entries.conf file looks like
    local-data: " A" 

    This works!

    $ dig +short @pf_sense_ip

    So, now i try to move the line:

    local-data: " A" 

    from the

    host_entries.conf file into the my_blocks.conf file.

    i do this over SSH with cp then nano to remove all but the last line and save the file and then i use the web UI to remove the host override / trigger a config rebuild / test.

    Here's the feedback i get:

    The generated config file cannot be parsed by unbound. Please correct the following errors:
    /var/unbound/my_blocks.conf:1: error: syntax error
    read /var/unbound/test/unbound.conf failed: 1 errors in configuration file

    The content of my_blocks.conf is identical to the last line of host_entries.conf before i used the webUI to remove that host override.

    SO!  My question.  Why does unbound refuse to parse my config file when i'm following the EXACT SAME pattern / using the EXACT SAME syntax that the webUI loads into host_entries.conf

    The moment i take the line i copies from host_entries out of my_blocks (making it an empty file again) unbound no longer complains about syntax!

    What am i doing wrong / please help me get unbound successfully blocking hosts!

  • Oh hey!

    I was able to fix it.
    I'm really not sure how i missed it, but i now have added a server: line above my_blocks

    It now reads as

    local-data: " A" 

    I no longer need to have web hosts overridden through the webUI :)
