Accessing remote AMQ with JConsole.
Hi,
I am having trouble using JConsole to monitor a remote AMQ. I can run AMQ
locally and JConsole works fine.
I have looked already at:
http://java.sun.com/j2se/1.5.0/docs/guide/management/agent.html#remote.
My batch file to run AMQ remote is:
java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1099
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false -jar AMQ.jar
I then try to launch JConsole is either:
jconsole service:jmx:rmi:///jndi/rmi://WAN_IP:1099/jmxrmi
or
jconsole WAN_IP:1099
Neither of these work remotely.
If I launch jconsole on the same machine as AMQ, using the exact two methods
immediately above, the connection WILL be made. The AMQ batch file then is
just (for this local mode):
java -Dcom.sun.management.jmxremote -jar AMQ.jar
Thanks.

What worked for me was modifiying the /etc/hosts file on the Red Hat box so
that the machine hostname resolves to actual ip address instead of
127.0.0.1. After changing, restart AMQ. Hope that helps.

I have tried adding the line: -Djava.rmi.server.hostname=x.x.x.x, but this
still doesn't do it. I can connect fine from a remote machine on the LAN,
even using the public WAN IP, but not from a machine not on the LAN, using
the WAN IP. I have eliminated firewalls, and set up virtual server settings
(IP address/port forwarding) on my router also. I'm running on Windows XP
(it's firewall disabled also per testing).

I found a solution to my problem. The answer was unrelated to AMQ or JMX.
It was due to weirdness in the /etc/hosts file on Red Hat Linux box. Fixing
this, fixed RMI, which fixed JMX and all's well. More info can be found at:

Re: Accessing remote AMQ with JConsole.

I've got the exact same problem. My set up: local box (Windows) with AMQ and
remote box (Red Hat Linux) with AMQ. Both boxes are running JDK 1.4.2. I
can use JConsole to monitor my local box but not the remote box. Another
clue -- I tried using the "list" command in the activemq/bin directory with
the --jmxurl argument. On local windows box, it works fine to access local
AMQ url but not remote AMQ url. If I run the list command on Linux box, I
can access both the Windows AMQ url as well as the Linux AMQ url. So it
appears to be some issue with Windows box connecting outbound to port 1099
on another box. My Linux admin tells me port 1099 on the Linux box is not
restristed by its firewall in any way. From windows box I can telnet to
port 1099 on Linux box and I can tell something's there listening. Anyone
have any ideas?
