我使用JMeter设置分布式负载测试环境。我在Windows Vista（主机）上运行Linux虚拟机（CentOS）。 Linux VM是JMeter Master（客户端）。我有一台服务器（Linux CentOS），它是我的JMeter Slave（服务器）。JMeter：分布式（远程）测试：无法远程运行测试
我做了以下：
1）增加了以下至客户机（主站）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）加入下列到服务器（从属）jmeter.properties：
server_port=55501
server.rmi.localhostname=172.22.222.22
server.rmi.localport=55511
3）增加了以下到服务器（从）JMeter的服务器：
RMI_HOST_DEF=-Djava.rmi.server.hostname=172.22.222.22
4）然后从我的主人，我所做的：然后
Using local port: 55511
Created remote object: UnicastServerRef [liveRef: [endpoint:[172.22.222.22:55511](local),objID:[637a4bg5:14185b4361e:-7fff, 894250217845851586]]]
6）：
ssh -R 55512:localhost:55512 172.22.222.22
5）然后，我开始JMeter伺服器：
sudo ./jmeter-server
我我的主人，我启动了JMeter GUI，并且做了 运行 - >远程启动 - > 172.22.222.22
我得到了以下错误：

任何人都可以请帮我找出我做错了什么，我怎么能解决这个问题呢？ 我试图在客户端和服务器上关闭iptables的，但我得到了同样的事情：
sudo service iptables stop
sudo chkconfig iptables off
有没有防火墙可以阻止连接？ –
请检查端口是否打开，本地和远程。你可以采取netcat。 – tfb785
