I think i found why this is not working, as you can see below, socket is connected and first message is sent (the initialize message), which is answered and the response is read ({“result”: true}).

Problem is (and i’ve testing with golang and python) after the answer the “initialize” message, the socket is closed, so, getAllDomains message is being sent using a closed socket and that’s why i don’t see it on the responder side and pdns does not receive and answer, polls 2 times and reaches timeout.

i can see there’s no test for unixsocket in the source tree.

So this arises my question to you, do you think my conclusion is ok? do the unixconnector.cc <http://unixconnector.cc/> should be modified?


Context, im moving out from http to unixsocket to gain in speed, im not sure if using pipes will improve that or the UDS is still the best option.

Thanks again!! regards
