perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hi Soichi;

The JOWPing client doesn't have a maintainer, so it is unlikely to be 
modified or included in future releases unless someone wants to claim 
ownership.  

With regards to owping - you need to provide the same ports to the client as 
well.  When you configure things via the FAQ that is only telling the server 
side to behave in that manner.  E.g. run owping with the -P option to specify 
a port range.  

Thanks;

-jason
