unbound v1.6.0 python module on debian 9

Fri Oct 26 09:09:19 UTC 2018

Hello, 

Did you try: 

apt-get install python3-unbound 

On Debian9 Unbound uses python3 iirc.

This is what I have: 

server: 
verbosity: 1 
statistics-cumulative: "yes" 
extended-statistics: "yes" 
num-threads: 2 
interface: "0.0.0.0" 
interface: "::0" 
interface-automatic: yes 
outgoing-port-permit: "32768-65535" 
outgoing-port-avoid: "0-32767" 
chroot: "" 
root-hints: "/etc/unbound/root.hints" 
module-config: "validator python iterator" 
directory: "/etc/unbound" 
cache-max-ttl: 300 
log-queries: no 
do-not-query-localhost: no 
include: /etc/unbound/unbound.local.d/*.conf 
python: 
python-script: "/etc/unbound/dns-backend.py" 
remote-control: 
control-enable: yes 
include: "/etc/unbound/unbound.conf.d/*.conf" 

Here's what I see when I try to run unbound: 

unbound -dv -c unbound.conf 
[1540500365] unbound[18398:0] notice: Start of unbound 1.6.0. 
Traceback (most recent call last): 
File "<string>", line 1, in <module> 
ImportError: No module named 'unboundmodule' 

However, it's there: 

ll /usr/lib/python2.7/dist-packages/ | grep unbound

Hi Christopher, 

What is the error you are getting from unbound? 
Can you share some bits of your configuration file? I am mainly 
interested in the following options: 
chroot: 
directory: 
module-config: 
python-script:

Thanks for the reply George. ?When I run what you suggested, I see 
/usr/lib/python2.7/dist-packages, and the unboundmodule.py is indeed in 
there. ?If I run my python script on it?s own from my shell, it works 
fine. ?unbound itself still does not see it, nor any of the other 
dependencies in that directory. ?Any idea why this might be?

I?m trying to set up a server running unbound and a python script. 
?This is working OK on an older server running version 1.4.2. ?On the 
newer one, I can?t seem to get unbound to see the python script 
dependencies. ?I do recall on the old server, this was because chroot 
was enabled. ?Once I disabled it in the config file via chroot: ??, 
it was fine. ?It?s disabled on the new one too, but still doesn?t 
seem to help. ?If I symlink the requested file from 
/usr/lib/python2.7/dist-packages/unboundpython.py to /etc/unbound/, 
that resolves that error, but more come up because of course it can?t 
see the other libraries. ?This leads me to believe that unbound isn?t 
looking out of /etc/unbound/ even though chroot is disabled. ?Is 
there something else I?m missing? 

I am assuming that you want to use a python script with unbound's python 
module. 

I see that when initializing the python module, unbound appends to the 
sys path also the directory reported by Python as the 
"platform-dependent include directory" [1]. 

You can find that directory by starting up the Python interpreter (the 
same that unbound will also use; in case of Python virtual environments) 
and typing: 

BQ_BEGIN

BQ_BEGIN
import distutils.sysconfig 
distutils.sysconfig.get_python_lib(1,0) 

BQ_END

BQ_END
'/usr/local/lib/python2.7/site-packages' (in my case) 

As a side note you can also achieve the same with chroot enabled but 
then you would need to link the same python directory structure inside 
the chroot in order for unbound to find the libraries.
