Re: c-Store failing even though c-Echo is successful

[Sébastien Jodogne]

I am trying to send from latest orthanc, running inside docker on ubuntu, to a PACS server running on Windows. I can successfully complete a c-Echo, but the c-Store fails saying that there is an error in the network protocol. I have followed the troubleshooting guide and do not know how to debug further, so if you could point me in the right direction, that would be great.

As written in the troubleshooting guide, this issue most probably reflects the fact that your PACS server does not know about your Orthanc instance:

http://book.orthanc-server.com/faq/dicom.html

http://book.orthanc-server.com/dicom-guide.html#dicom-move

In other words, for a DICOM query/retrieve request between modality "A" and PACS "B" to succeed, "A" must know about "B" *and* "B" must know about "A". In your case, the second part of the condition is most probably not true.

HTH,

Well, C-Store and C-Move requires the same kind of configuration.  Do you mean you've been able to issue a C-Move and not a C-Store ?

Could you provide us with your configuration file, Orthanc IP address, PACS AET, IP and port.

On your PACS, what did you enter to configure the Orthanc modality ?

On your PACS, are your sure this modality is allowed to perform C-Store ?

I am seeing this issue with c-Store, not c-Move. I don't think the same issue applies.

Hello,

 

No, I have not tried to perform a C-Move. Only a C-Store via the web ui. [...] Here is the configuration of the PACS server. It is more of a proxy (CTXNode) provided by CortechLabs. I have also attached a usage guide they provided. From what I see, it makes sense that they would expect a C-Store

Please also provide the logs of Orthanc (cf. http://book.orthanc-server.com/faq/log.html) and the logs of your CTXNode.

Hard to say anything without the logs from CTXNode. The important part of the Orthanc log is:

Are you sure that "neuroquant_age" is really the AET of CTXNode? This is a strange AET name, as it should be in uppercase. Haven't you swapped the AET of the modality, with the symbolic name assigned to the modality in Orthanc? In other words, shouldn't you write:

>>>>>

"DicomModalities" : {

    "neuroquant_age" : [ "AGE-RELATED-ATROPHY-REPORT", "XX.XXX.XX.XXX", 4242 ]

}

<<<<<

Also, it is strange that the AET of CTXNode is 4242 (the DICOM port used by Orthanc). Shouldn't it be set to 104?

From what I understand from this image:

You should use:

   "neuroquant-age" : [ "neuroquant-age", "XX.XXX.XX.XXX", 4567 ],

If this does not help, you have to get in touch with the network administrator of your CTXNode. He is the only one to have full knowledge of all the network topology. It is for example possible that a firewall is blocking your connections from Orthanc to CTXNode. As far as we are concerned, we cannot remotely provide any additional hint.

[airr...@cortechslabs.com]

I'm trying to help Haydn figure this out - we have looked at all the configuration settings and they are correctly set as:

Orthanc:
IP: localhost
Port:4242
AET: ORTHANC

CTXNode:
IP: localhost (testing on same machine at this point)
Port:4567
AET: neuroquant_age

Remote modality settings on Orthanc:

"neuroquant-ctxnode" : [ "neuroquant_age", "localhost", 4567 ]

Can echo CTXNode from Orthanc successfully but when trying to send an MR study over we get the attached error (pretty much instantly). Log messages on the Orthanc side are:

E0106 16:38:20.034551 DicomUserConnection.cpp:166] DicomUserConnection: Peer aborted Association (or never connected)
E0106 16:38:20.050446 StoreScuCommand.cpp:86] Unable to forward to a modality in a Lua script (instance 91b9d396-cbf9846c-7d095904-67148e62-bd5300df): Error in the network protocol
E0106 16:38:20.055924 ServerScheduler.cpp:122] Job has failed (HTTP request: Store-SCU to peer "neuroquant-ctxnode")

On CTXNode there is no sign of a connection being made - nothing in the logs at all. tcpdump shows traffic to port 4567 however.

CTXNode can send to Orthanc.

Orthanc can send to a dummy server (dcmtk) on the same system and port.

Every other PACS, viewer etc we have ever tested can send to CTXNode (which uses dcm4chee to receive DICOM objects).

Seems like there is a network protocol incompatibility of some kind. What transfer syntax does Orthanc use by default when sending? Anything else you can think of?

Thanks,

Chris

From my point of view, the "Peer aborted Association (or never connected)" indicates that CTXNode does not know about your Orthanc server, and blocks your connection.

Have you properly defined Orthanc in the configuration of CTXNode? In DICOM, both software must about each other:

http://book.orthanc-server.com/faq/dicom.html

Double-check the AET, IP and port of Orthanc, as defined in the CTXNode configuration.

As of Orthanc 1.2.0, Orthanc never changes the transfer syntax of the files to be sent (no transcoding). Make sure that CTXNode supports the transfer syntax of your DICOM file.
