Pynetdicom Across Virtual Machine with Port Forwarding

Description

QUESTION - How to access PACs server on Virtual Machine?

I have a linux box running on Virtual Box where i have setup Conquest Open Source PAC server. https://ingenium.home.xs4all.nl/dicom.html

Using pynetdicom on the virtual machine i can connect the to server and retrieve data. Then i have setup Port Forwarding on the VirtualBox instance so i should be able to access it from my local machine. Indeed, a connection is established, but no data is returned.

This is the script being run - https://pastebin.com/7tuqaX39

Expected behaviour

The connection is established and query status returns 0xff00, data is returned, status returns 00x000 and the connection is released.

Actual behaviour

The connection is established and query status returns 0x000 and the connection is released.

Association Established C-MOVE query status: 0x0000 Association Released

Steps to reproduce

Install conquest on linux virtual machine. Setup port forwarding. Run this script from the host machine - https://pastebin.com/7tuqaX39

Your environment

Please run the following and paste the output.

$ python -c "import platform; print(platform.platform())"
$ python -c "import sys; print('Python', sys.version)"
$ python -c "import pydicom; print('pydicom', pydicom.__version__)"
$ python -c "import pynetdicom; print('pynetdicom', pynetdicom.__version__)"

On the host machine

 python -c "import platform; print(platform.platform())"
Darwin-18.2.0-x86_64-i386-64bit
 python -c "import sys; print('Python', sys.version)"
Python 3.6.1 |Anaconda custom (64-bit)| (default, May 11 2017, 13:04:09) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)]
 python -c "import pydicom; print('pydicom', pydicom.__version__)"
pydicom 1.2.1
python -c "import pynetdicom; print('pynetdicom', pynetdicom.__version__)"
pynetdicom 1.1.0.dev0

Looking at your script the first part is for a C-FIND request, not C-MOVE. Is that correct? If so then I have no explanation on why you’re not getting any (0xFF00) pending responses before the (0x0000) success response. The simple fact that you are getting a success response tells me that everything on the pynetdicom side is working as expected, so I suspect its an SCP config issue.

Assuming thats the case:

1. Could you confirm that your Conquest configuration is set up correctly for handling associations from the local machine (perhaps in the known DICOM providers)? I’m not familiar with Conquest, but perhaps confirm that access to the QR service has been permitted for the local machine’s SCU (if applicable).
2. Are you able to run C-FIND requests as expected with DCMTK’s findscu?

If both those points are OK, could you run the SCU with a debug log level and post the output?

import logging
from pynetdicom import AE
etc...

LOGGER = logging.getLogger('pynetdicom')
LOGGER.setLevel(logging.DEBUG)

ae = AE()
etc...

So are you happy that things are working as expected? Can I close the issue?
