Hi, Johan;
Thanks for the report! Perhaps hit the client with a couple or three -v
options to increase the debugging details for me...
The output will be big so of you can capture it in a file that will
probably be best.

Hi,
this looks like a nice project and I started looking into whether it might
be useful for writing tests for an EtherIP communication project we have.
We're using a C EtherIP library from
http://ics-web.sns.ornl.gov/kasemir/etherip/ and it's working fine for
communicating with our Allen-Bradley PLCs.However, I have trouble getting that library to talk to the cpppo test
server and I'm wondering if this should even be expected to work. This is
what I'm doing:Starting the test server:
python -m cpppo.server.enip --print SCADA=INT[1]
and then I run the test program included with the EtherIP library:
./ether_ip_test -v 10 -i 127.0.0.1 -p 44818 SCADA
The result is "No response" and the server prints out the following

Ah, that was fast! :)
I did the exact same test with more verbosity and it wasn't horribly huge so I'm pasting it anyway. Here you go:

The ListServices (EtherNet/IP service 0x04) request has not yet been implemented. Up to this point, we've been using cpppo's EtherNet/IP CIP functionality with industrial scanning software that doesn't require this service. I am implementing it now...

Sounds great! It would be pretty cool if we could use cpppo for the client too, as it's a bit of a pain to build the C library and develop a python binding for it.
I'd be happy to provide more information or testing.

I have implemented ListServices in version 3.3.0; these tests now pass. Thanks so much for the report! Let me know if you see anything else, or if you need a hand integrating your solution.
