In the testbed the hostagent somehow can not connect to the AgentManager within mininet.
I am running the control message drop attack.
When executing in mininet
java -jar $HOME/delta-agent-host-1.0-SNAPSHOT.jar 10.0.3.1 3366
the following error occurs
java.net.NoRouteToHostException: No route to host (Host unreachable)

Full output of host agent

I verified that the agent manager is listening on Port 3366, which is true.
netstat -tulpn | grep LISTEN gives

In addition it is possible to connect from the DELTA_CP container to 10.0.3.1:3366
nc -zv 10.0.3.1 3366

What might be the issue here?
I also verified in the source code that it gets the right paramters.
