I'm not sure I'd know what I'm looking at, but started "iperf3 -s p 5001" in background on psonar-bwctl then ran tcpdump -i p1p1 host 165.91.55.4 (psonar-owamp, test client).  Output is attached as tcpdump1.txt.  I ran tcpdump on 2nd test with -XX and -vvv and attached as tcpdump2.txt.

Thanks,

Hi Trey,

If you have root on the suspect box, run tcpdump during a test that fails and see what's going on.

Measurement tools are wonderful and helpful and valuable, but if things are busted enough that the tools can't run, sometimes you just have to watch the packets to figure out what's going on....

Transferring a 4.3GB file fails...very bizarre.  The transfer started then scp reports "stalled".

The failure is between the 2 perfsonar boxes.  Transferring to a perfsonar box from a host on our campus LAN and not on our science DMZ works at the expected 1Gbps rate.

Transferring from another science DMZ host (stock CentOS) to the perfsonar box fails.

Transferring from science DMZ to science DMZ, both stock CentOS boxes, works.  So it's only the interactions with perfsonar host that fail.

I'm suspecting something local is broken and just so happens it's effecting interactions to/from my perfsonar boxes.

If there's any suggestions on how to debug I'd be glad to hear them, but seems like something is broken on our local network.

Thanks,

Hey Trey,

That is bizarre. Could you try scp’ing a large file between the two hosts?

Yes, it occurs in both directions between psonar-bwctl.brazos.tamu.edu and psonar-owamp.brazos.tamu.edu.

If I run the server side on either of those boxes and try and run the client from a plain CentOS host the tests also don't work.

These systems are both stock net installs of PS 3.4

Does this happen in both directions?

As the remote end was not setup by me I can't test this particular host, but instead I've tried iperf between my latency PS host and bandwidth PS host and got same results.  Below are results using iperf3 and nuttcp.  With iperf the connection seemed to stall at first then produce 0 bits/sec messages, but with iperf3 it rapidly printed the interval lines.

I'm not aware of anything that might explain that. Can you try iperf3 and nuttcp to see if they behave the same?

Right now most of the endpoints I'm testing against seem to not work with bwctl so to help some colleagues I've been trying to just use iperf by itself.  From my perfsonar boxes the iperf tests seem to do nothing while a non-perfsonar host with iperf installed from EPEL gives expected output.  The results are below.  I've removed the remote information as these were not against a perfsonar box but a remote site's cluster login node.

Is there something about iperf on a PS host that could cause this issue?  The 2 systems below are on same network and same core switch.
