virtual server configuration

  • I have a conquest 1.4.17 installation running on XP 32 bit, that I am trying to use as a virtual server.


    Initially, I have one test server, with AET of RELAY, the conquest virtual server with AET of GATEWAY and a client AET of CLIENT.


    Both server and client are in acrnema.map, config in conquest is:


    # Configuration of the virtual server
    CacheVirtualData = 1
    OverlapVirtualGet = 0
    VirtualServerFor0 = RELAY


    If I make a query from CLIENT to GATEWAY, I reliably get a valid response from server RELAY with a list of studies, but if I try to retrieve, the retrieve fails at the client with a timeout - and Conquest does not seem to even try and retrieve the image from RELAY when I look in the log there.


    Here is a query followed by a retrieve request:


    [GATEWAY]
    [GATEWAY] UPACS THREAD 5: STARTED AT: Fri Jun 13 16:29:29 2014
    [GATEWAY] Calling Application Title : "CLIENT "
    [GATEWAY] Called Application Title : "GATEWAY "
    [GATEWAY] Application Context : "1.2.840.10008.3.1.1.1", PDU length: 116794
    [GATEWAY] Presentation Context 0 "1.2.840.10008.5.1.4.1.2.2.1" 1
    [GATEWAY] (StudyRootQuery) search level: STUDY
    [GATEWAY] C-Find (StudyRoot) located 1 records

    [GATEWAY] Calling Application Title : "CLIENT "
    [GATEWAY] Called Application Title : "GATEWAY "
    [GATEWAY] Application Context : "1.2.840.10008.3.1.1.1", PDU length: 116794
    [GATEWAY] Presentation Context 0 "1.2.840.10008.5.1.4.1.2.2.2" 1
    [GATEWAY] C-Move Destination: "CLIENT "
    [GATEWAY] C-Move (StudyRoot)
    [GATEWAY] UPACS THREAD 6: ENDED AT: Fri Jun 13 16:29:45 2014
    [GATEWAY] UPACS THREAD 6: TOTAL RUNNING TIME: 1 SECONDS

    To sum up, then, CLIENT can succesfully query RELAY via GATEWAY. GATEWAY can use its own query/move function to query and retrieve a study from RELAY and CLIENT, in turn, can successfully retrieve a study already present on GATEWAY.


    It is just the last step that fails - that of GATEWAY retrieving from RELAY and passing it to CLIENT. The logs on RELAY show no signs of GATEWAY ever trying to retrieve, only query.


    I'm sure I'm missing something basic, but what?


    Any thoughts?
