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

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/
