Tool doesn't seem to be working.

Hi Nitsan,

I'm trying your tool in EC2 and can't seem to get it working.

on server:
java -jar lib/java-ping.jar -client -select 10.0.0.228 5701 1
java -jar lib/java-ping.jar -server -block 10.0.0.228 5701

On the client I can see:

[simulator@ip-10-0-0-73 ~]$ java -jar lib/java-ping.jar -client -select 10.0.0.228 5701 1
Pinging 10.0.0.228:5701 messages of size 1
Min,50%,90%,99%,99.9%,99.99%,Max

But nothing happens.

I can see they are connecting. If I insert a wrong address on the client I get an error. And if I terminate while the client is 'freezing' the client throws an exception.

There are no firewall issues. I can run simulator (java based benchmark/soak test environment) on the environment without problems. I explicitly set the ports since I know these are open.

When I place both client and server in -block mode and kill the server when the client is connecting, the client starts to output

[simulator@ip-10-0-0-73 ~]$ java -jar lib/java-ping.jar -client -block 10.0.0.228 5701 1

Even though the java server has been killed with a 'killall -9 java'. So there is nothing running but the client is still reporting latencies
