JMeter: Distributed (Remote) Testing: Unable to run tests remotely - jmeter

Question

I setup a distributed load testing environment using JMeter. I am running a Linux Virtual Machine (CentOS) on my Windows Vista (Host). The Linux VM is the JMeter Master (client). I have a server (Linux CentOS) that is my JMeter Slave (server).
I did the following:
1) Added the following to client (master) jmeter.properties:
remote_hosts=172.22.222.22:55501 #IP address of the JMeter Slave
client.rmi.localport=55512
mode=Batch
num_sample_threshold=250
2) Added the following to server (slave) jmeter.properties:
server_port=55501
server.rmi.localhostname=172.22.222.22
server.rmi.localport=55511
3) Added the following to server (slave) jmeter-server:
RMI_HOST_DEF=-Djava.rmi.server.hostname=172.22.222.22
4) Then from my Master, I did:
ssh -R 55512:localhost:55512 172.22.222.22
5) Then I started the jmeter server:
sudo ./jmeter-server
I got:
Using local port: 55511
Created remote object: UnicastServerRef [liveRef: [endpoint:[172.22.222.22:55511](local),objID:[637a4bg5:14185b4361e:-7fff, 894250217845851586]]]
6) Then from my Master, I launched the JMeter GUI, and did
Run --> Remote Start --> 172.22.222.22
I got the following error:
2013/10/04 16:03:06 ERROR - jmeter.gui.action.RemoteStart: Failed to initialise remote engine java.rmi.ConnectException: Connection refused to host: 172.22.222.22; nested exception is:

Can anyone please help me figure out what I did wrong, and how can I resolve this issue?
I tried turning off iptables on both client and server, but I get the same thing:
sudo service iptables stop
sudo chkconfig iptables off

Answer 1

I have seen this issue. You need to setup reverse SSH tunnels from master to client for results transfer. Check this: http://rolfje.wordpress.com/2012/02/16/distributed-jmeter-through-vpn-and-ssl/

Answer 2

See my answer here
I think the only way to work around this is to setup a full featured VPN.
