Subject Re: telnet to slave @ 1099 OK but Connection refused from jmeter-server
Date Mon, 04 Feb 2008 12:42:59 GMT
Turns out that the problem was on the client node - it was sending its
address as 127.0.1.1, so of course the server could not reply to it.

That's why the test started OK, but failed when a sample was generated.
