PORT ISSUE

Hey!, I’m using pynetdicom3 with Orthanc. Starting from the SCP verification, in the beginning everything goes fine orthan ECHOES and succeed. But as I continue working on other things after sometime the same program fails to echo back. When I echo from orthanc it fails on that port. But if I use some other port it is back to normal.

    from pynetdicom3 import AE, VerificationPresentationContexts

    ae = AE(ae_title=b'leo', port=11111)
    ae.supported_contexts = VerificationPresentationContexts
    ae.start()

any suggestions?

Typically how many C-ECHO requests and/or how long before it stops working on that port?

Is your SCU port 1111 or 11111? If its 11111 you probably shouldn’t use the same port for both SCU and SCP.

I’ve just run 1000 associate -> C-ECHO request -> release runs against the echoscp in apps listening on port 11113 and haven’t had any issues. Could you run the following and tell me if it succeeds or not?

#!/usr/bin/env python

import logging

from pynetdicom3 import AE
from pynetdicom3.sop_class import VerificationSOPClass

LOGGER = logging.getLogger('pynetdicom3')
#LOGGER.setLevel(logging.DEBUG)
LOGGER.setLevel(logging.ERROR)

ae = AE(ae_title=b'mysc', port=11112)
ae.add_requested_context(VerificationSOPClass)

for ii in range(1000):
    assoc = ae.associate('127.0.0.1', 11113)
    if assoc.is_established:
        status = assoc.send_c_echo()
        if 'Status' in status:
            print('C-ECHO status: 0x{0:04x}'.format(status.Status))
        assoc.release()

Did you end up figuring out what was causing the issue?
