perfSONAR User Q&A and Other Discussion

[<>]

Hello,

I recently found one of our servers failed running owping tests against other
servers. It can ping other servers. Meanwhile, other servers can run owping
against this owping-defaulty server. Noted all of them have the same
configuration.

The specific error showed below with the "server denied test". If I run owping
test from a to b I will get 100% packet loss. I read this post
'https://lists.internet2.edu/sympa/arc/perfsonar-user/2014-08/msg00044.html'
and tried to change the bandwidth from 20M to different values but had no
luck. Feel free to drop any suggestions. Thanks!
