Trying to get unbound + pythonmod to work

Unbound
1

Hi.

When I run
sudo unbound -d -vv -c /usr/local/etc/unbound/unbound.conf

I get the following in syslog:

unbound: [18452:0] debug: chdir to /usr/local/etc/unbound
unbound: [18452:0] debug: module config: "validator python iterator"
unbound: [18452:0] error: Unknown value for next module: ' python
iterator'
unbound: [18452:0] fatal error: failed to setup modules

unbound.conf follows the guide in the pythonmod/doc
( http://www.fit.vutbr.cz/~vasicek/nic-vip/pythonmod/examples/example0.html )

Where I have the line:
module-config: "validator python iterator"

I got unbound-1.4.1 (apt-get source, through Ubuntu 10.04, lucid )
SWIG 1.3.40

Here's how I installed unbound:
./configure --with-pythonmodule
make
sudo make install

Following the testing instructions in pythonmod/doc/install.rst
sudo make test
gives the the same result as above:

./unbound -dv -c ./test-resip.conf
[1299845059] unbound[19650:0] notice: Start of unbound 1.4.1.
[1299845059] unbound[19650:0] warning: did not exit gracefully last time
(17067)
[1299845059] unbound[19650:0] error: Unknown value for next module: '
python iterator'
[1299845059] unbound[19650:0] fatal error: failed to setup modules
make: *** [test] Error 1

Any suggestions to what I may try next?
Could it be that pythonmod is not built? The directory build/pythonmod
does contain a set of .o & .lo files.

Javier,

unbound: [18452:0] debug: module config: "validator python iterator"
unbound: [18452:0] error: Unknown value for next module: ' python
iterator'

Based on the other information in your email, it appears that you have
compiled in support for python, so I would suggest changing your module
config to "python validator iterator". I was only able to get Python
support working when python appeared first.

I just found this in the source of "unbound-checkconf.c":

    && strcmp(cfg->module_conf, "python iterator") != 0
    && strcmp(cfg->module_conf, "python validator iterator") != 0
    && strcmp(cfg->module_conf, "validator python iterator") != 0

But I can't find a resource saying _why_ those wouldn't work.

Anyawy, now i'm runing it with:

module-config: "python"

and getting:

Mar 11 14:57:23 dab unbound: [4611:0] warning: did not exit gracefully
last time (2858)
Mar 11 14:57:23 dab unbound: [4611:0] debug: chdir
to /usr/local/etc/unbound
Mar 11 14:57:23 dab unbound: [4611:0] debug: module config: "python"
Mar 11 14:57:23 dab unbound: [4611:0] error: Unknown value for next
module: 'python'
Mar 11 14:57:23 dab unbound: [4611:0] fatal error: failed to setup
modules

Does any one have any suggestions on what to try next?
What does "known value for next module: 'python'" mean?

Ok, "sudo make test" in pythonmod/ now works.

I removed all modules except for "python".
I ran "./configure --with-pythonmodule"
Checked config.h that WITH_PYTHONMODULE was defined to 1
ran
make clean
make
sudo checkinstall (debian-style make install).

and now it seems to work.

I'm still wondering whether or not I'm allowed/recommended to use the
python module _and_ valdiator/iterator or not.

Hi Javier,

The first error was because you did not compile support for the python
module.

This error is because you have not understood the code, checkconf checks
the module list, if the combination can work.
