None of the connections listed there are the opscenter process. You can change the interface the web server binds to in the opscenterd.conf file. <a href="http://www.datastax.com/docs/opscenter/configure/configure_opscenter_adv" rel="nofollow">http://www.datastax.com/docs/opscenter/configure/configure_opscenter_adv</a> Abhijit on "OpsCenter" http://www.datastax.com/support-forums/topic/opscenter#post-3125 Mon, 16 Jul 2012 11:12:00 +0000 Abhijit 3125@http://www.datastax.com/support-forums/ Hi, I have SSL installed in my machine as well as rest of all the settings are up to mark.

You will need to allow access to port 9160 on your cassandra servers in order for OpsCenter to be able to connect. Can you verify that port 9160 is open?

It was missing SSL. But currently I am not able to connect to the cassandra cluster using the opscenter dashboard. The cluster has been configured in aws instance. I am using public dns of the child node cluster instance to add the cluster in the opscenter dash board but getting the connection error.

Traffic to the public dns should redirect to this. Also, make sure that your security rules permit external tcp traffic on port 8888.

There I in /etc/opscenterd/opscenterd.conf i have set the interface as public dns of the instance. Please let me know if I am missing something. Regards, Shankha thobbs on "OpsCenter" http://www.datastax.com/support-forums/topic/opscenter#post-1888 Thu, 10 May 2012 17:15:33 +0000 thobbs 1888@http://www.datastax.com/support-forums/ Hi Shanka, By default, the OpsCenter webserver only listens on 127.0.0.1, so if you need to access it from another machine, you need to edit <code>/etc/opscenterd/opscenterd.conf</code> and set the <code>interface</code> option under the <code>[webserver]</code> section to something else, like the ip address of the machine. After changing this, restart opscenterd and try again.

When I start the opscenterd service using "sudo service opscenterd start" I am able to see the process using "ps -ef|grep opscenter" root 1024 1 0 11:06 ? 00:00:00 /usr/bin/python2.7 /usr/share/opscenter/bin/twistd -u 0 -g 0 --pidfile /var/run/opscenter/opscenterd.pid -y /usr/share/opscenter/bin/start_opscenter.py ubuntu 1681 1551 0 14:06 pts/1 00:00:00 grep --color=auto opscenter But when I try to access the web console through browser hitting <a href="http://<ip>:8888" rel="nofollow">http://<ip>:8888</a> I am getting "Connection Refused". Can anyone help out please? Thanks Shankha
