Response generation
|
|
===================
|
|
|
|
This example shows how to handle queries and generate response packet.
|
|
|
|
.. note::
|
|
If the python module is the first module and validator module is enabled
|
|
(``module-config: "python validator iterator"``), a return_msg security flag
|
|
has to be set at least to 2. Leaving security flag untouched causes that the
|
|
response will be refused by unbound worker as unbound will consider it as
|
|
non-valid response.
|
|

|
Complete source code
|
|
--------------------
|
|
|
|
.. literalinclude:: ../../examples/resgen.py
|
|
:language: python
|
|
|
|
Testing
|
|
-------
|
|
|
|
Run the unbound server:
|
|
|
|
``root@localhost>unbound -dv -c ./test-resgen.conf``
|
|
|
|
Query for a A record ending with .localdomain
|
|
|
|
``dig A test.xxx.localdomain @127.0.0.1``
|
|
|
|
Dig produces the following output::
|
|
|
|
;; global options: printcmd
|
|
;; Got answer:
|
|
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 48426
|
|
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
|
|
|
|
;; QUESTION SECTION:
|
|
;test.xxx.localdomain. IN A
|
|
|
|
;; ANSWER SECTION:
|
|
test.xxx.localdomain. 10 IN A 127.0.0.1
|
|
|
|
;; Query time: 2 msec
|
|
;; SERVER: 127.0.0.1#53(127.0.0.1)
|
|
;; WHEN: Mon Jan 01 12:46:02 2009
|
|
;; MSG SIZE rcvd: 54
|
|
|
|
As we handle (override) in the python module only queries ending with
|
|
``localdomain.``, unboud can still resolve host names.
