perfSONAR User Q&A and Other Discussion

[Rodesch Christian <>]

Hello,

I was finally able to install the perfsonar MP. After configuring and 
testing, I'm now at the point that measuring in one direction works but 
in the other doesn't.

So I tried to measure using the bwctl command tool and this is the result:

       bwctl -s 193.198.229.166 -c 158.64.56.218
       bwctl: 16 seconds until test results available

       RECEIVER START
       3420191373.062331: iperf -B 158.64.56.218 -P 1 -s -f b -m -p
       5002 -t 10
       ------------------------------------------------------------
       Server listening on TCP port 5002
       Binding to local address 158.64.56.218

       ------------------------------------------------------------
       [ 13] local 158.64.56.218 port 5002 connected with

       [ 13] MSS size 1448 bytes (MTU 1500 bytes, ethernet)

       RECEIVER END

Like I said, measuring in one way (our server as receivehost) works well 
but:

       eomer:/var/www # bwctl -s 158.64.56.218 -c 193.198.229.166
       bwctl: 16 seconds until test results available

       RECEIVER START

       RECEIVER END


Unfortunately if I take our server as sendhost it doesn't work and I 
only get the upper output.

Is this due to a missing authentication or what else could be the problem?

BTW: I tested with many servers, which I found in the list of perfSONAR 
UI, and except some servers which directly ouput "Access denied", I 
always get the upper message.

Thanks in advance for any help!
