storescp: "Illegal service parameter: Calling AP Title"

[marcelopham]

Hello,

I'm a dcmtk newbie and experiencing an issue: I start the storescp server with these arguments:

Code: Select all

$ storescp -v -d -aet XTEST -pdu 65536 8104

Then, sending from a Windows-based DICOM client with the AE Title XTEST is giving me this error:

Code: Select all

D: ======================= END A-ASSOCIATE-RQ ======================
E: Illegal service parameter: Calling AP Title
E: 0006:030c Illegal service parameter: Calling AP Title

Analyzing the log, I found that the "Calling Application Name" is empty, and different from the "Called Application Name" (XTEST), which may be not allowing the Association Request:

Code: Select all

D: Our Implementation Class UID:      1.2.276.0.7230010.3.0.3.6.0
D: Our Implementation Version Name:   OFFIS_DCMTK_360

D: Called Application Name:     XTEST
D: Responding Application Name: 
D: Our Max PDU Receive Size:    65536
D: Their Max PDU Receive Size:  65536

The only weird thing is, when testing the connection from the client (the client has a "Test" button) the connection is successful:

Code: Select all

I: Association Release

Am I calling the storescp with the wrong parameters? Or the DICOM client is not compatible? Are the different Implementation Class UID's an issue as well?

Thanks a lot in advance!!!!

Did you specify a (Calling) AE Title for the Storage Service on the SCU side? An empty AE Title is not allowed.
By the way, there is no need to use the same value for Calling and Called AE Title; usually they are different.

Thanks - Yes, I setup the DICOM client (Windows based) to use the following settings:
- server: finisterre-server (same host name as the server where storescp is running)
- Calling AE Title: XTEST
- Port: 104
