perfSONAR User Q&A and Other Discussion

[Rodesch Christian <>]

Hi again,

well I've done some research using wireshark and the result is that even 
though perfsonar UI does show a blank result screen, a valid XML result 
is being send by the BWCTL MP host:

So here's the request XML from the perfsonar UI client

   POST /services/MP/BWCTL HTTP/1.0
   Content-Type: text/xml; charset=utf-8
   Accept: application/soap+xml, application/dime, multipart/related,
   text/*
   User-Agent: Axis/1.4
   Host: 158.64.56.218:8090
   Cache-Control: no-cache
   Pragma: no-cache
   SOAPAction: ""
   Content-Length: 1181

   <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope
   xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";

           <nmwgt:dst type="ipv4" value="158.64.56.116"/>
         </nmwgt:endPointPair>
       </perfsonar:subject>

       <nmwg:eventType>bwctl</nmwg:eventType>
       <nmwg:parameters id="param1">
       <nmwg:parameter name="protocol" value="TCP"

     <!-- triggers to indicate head of chains -->
     <nmwg:data id="1" metadataIdRef="meta1"/>

And this is the result from the BWCTL MP Host

As you can see, the reply xml contains the result values, therefore I 
think that the problems comes from perfSonar UI, maybe the parser has 
some problem. I'm using the Java Webstart version 0.11 of perfSonar UI. 
Maybe there is a newer one?

However, I'm quite happy now that the 2 hosts are working fine :-)

Thanks for your help

Christian
