Maki, thanks for your reply. for the second question, I wasn't using the
loopback address, I was using the actually IP address for that server. I am
able to telnet to that IP on port 8081, but using jconsole failed.

Subject: Re: cluster IP question and Jconsole?
127.0.0.2 to 127.0.0.5 are valid IP addresses. Those are just alias
addresses for your loopback interface.
Verify:
% ifconfig -a
127.0.0.0/8 is for loopback, so you can't connect this address from
remote machines.
You may be able configure SSH port forwarding from your monitroing
host to cassandra node though I haven't try.

I have followed the description here
http://www.edwardcapriolo.com/roller/edwardcapriolo/entry/lauching_5_node_cassandra_clusters
to created 5 instances of cassandra in one CentOS 5.5 machine. using
nodetool shows the 5 nodes are all running fine.
Note the 5 nodes are using IP 127.0.0.1 to 127.0.0.5. I understand
127.0.0.1
is pointing to local server, but how about 127.0.0.2 to 127.0.0.5? looks
to
me that they are not valid IP? how come all 5 nodes are working ok?
Another question. I have installed MX4J in instance 127.0.0.1 on port
8081.
I am able to connect to http://server:8081/ from the browser. However how
do
I connect using Jconsole that was installed in another windows
machines?(since my CentOS5.5 doesn't have X installed, only SSH allowed).
Thanks.
