Subject Need help for udp port testing blueprint
Date Mon, 03 Jul 2017 14:29:29 GMT

I made a blueprint which opens tcp and udp ports and makes assertions 
for port reachability. [1]
The blueprint is testing the reachability of ports with ncat.
It is working for TCP but not for UDP.
I am also using

In case deploying `org.apache.brooklyn.udp.tests` blueprint against AWS 
machines (applicable for AWS BYON nodes), udp port server says no 
messages went through.
When testing manually the nc commands against AWS machines udp packets 
are going through.
When testing with the blueprint against localhost, it is working.
See examples. [2]
Tried with other port numbers, same result.
Could you assist me with that check, thanks.
