GUI client hangs trying to start remote test
Not sure why. Server is running on port 10130; I can telnet to that
port successfully.
My issue seems similar to this poster:

Any ideas?
2008/10/03 15:33:20 ERROR - jmeter.engine.ClientJMeterEngine:
java.rmi.ConnectException: Connection refused to host: 75.149.167.25;
nested exception is: java.net.ConnectException: Connection timed out

I suspect that is how the sample results are returned.
Maybe if you did not have any listeners in the test plan (and no -l
flag on the GUI command-line) the test would work without allowing the
back-channel. But it would not be very useful...

I have a lot to learn about RMI, but after a little bit of digging I
think that connecting directly to the client is only necessary if you
want to do make RMI calls *from* the server. I gather JMeter does.

Remote Testing -> Tips (section 15.2 in the v2.3.2 user's manual)
would be a good place.

Yes, the return connection is a feature of how RMI works.
If you can suggest where best to put this info in the JMeter docs -
i.e. where you would go looking for it - I'll add it.

Hi Sebb, sorry for the slow response, and thank you very much for your
help so far.

That's strange! I've commented out the relevant line in /etc/hosts on
the client, but I can't see how that would have adversely affected
networking.

Interesting. Still not sure how a mapping for 127.0.1.1 would mess
things up... then again, I don't know how Java gets the host name.

Client is firewalled from inbound traffic, server is not firewalled.
> Are you sure the client is using the correct port?
Ok, I noticed the server was trying to connect *back* to the client on
a high TCP port. I opened this port and now I can run JMeter tests
remotely. Does it make sense that the server needs a direct connection
back to the client? I don't remember reading about this in the JMeter
user manual.

The client log shows:
IP: 127.0.1.1 Name: scraps FullName: scraps
which means that the client /etc/hosts is not set up correctly.
However, that normally only affects the server.
Normally, the error "Connection refused to host" means that the client
cannot connect to the host, but you say that telnet works to the
server port. Are there any firewalls or routers in between the client
and server?
Are you sure the client is using the correct port?

Are the IP addresses XXX.XXX.XXX.XXX in the client and server logs the same?

And here's the JMeter script: http://tinyurl.com/43deda
I've changed the hostname and some parameters of the test plan since
this is a public mailing list.
