There's a little-known change in the way JMX uses ports that was add to
JDK7u4 which simplifies the use of JMX in a firewalled environment.
The standard RMI registry port for JMX is controlled by the
com.sun.management.jmxremote.port property. The change to Java 7 was to
introduce the related com.
The way RMI (which JMX uses, which is what nodetool uses) works is it will
first connect, then send a address/port back over the wire for it to make a new
2nd connection too. This will be potentially to a different address then
127.0.0.1 (can override with -Djava.rmi.server.hostname= in
/etc/c
I’ve done an install on an amazon instance, and for some strange reason I can
telnet to the JMX port, but node tool just hangs and doesn’t do anything. I am
hoping I’m overlooking something simple that someone could help me point out?
Thanks (:

Do you allow both outbound as inbound traffic? You might also try allowing
both TCP as UDP.
