How can be sure about that is slave machine's response data return correctly in JMeter distributing testing?

I want to make a distributing testing.When I tested target sites in my master computer;return response data correctly,but when I tested target sites from remotely(slave machine),response data is empty and starting the test on host "slavemachine's ip",finished the test on host "slavemachine's ip"appears slave machine's jmeter-server.I did the steps in this link carefully. http://ift.tt/1HjCqAJ

How can be sure about that is slave machine's response data return correctly in JMeter distributing testing? Thanks in advance...
