perfSONAR User Q&A and Other Discussion

[Michel Vale Ferreira <>]

Hello, This is my first post. I'm assessing using Owping on probes using 
OpenWRT at users' homes.

I've downloaded the I2Util and Owamp sources and had to make a little 
patch and Makefiles to compile them for OpenWRT. When running owping 
I've seen that it auto-negotiates a port on each side and send the packets.

Our scenario includes absolute control in one end (the server running 
owampd) and one end with no control (the user running owping), so the 
user might be behind NAT or Firewall.

In that scenario the probe sends and the server receives all the 
packets, but the client loses all packets from the server. I'd like to 
know if it's possible to use the owping (owamp protocol) starting on the 
client but receiving the packets on the same socket, so it works in both 
ways, as I'm interested on the latency and jitter, regardless of the 
connectivity on the client.
