I am unfamiliar with enabling/disabling firewalls on windows machines though. I'm not sure what the process is for that. </p> http://www.datastax.com/support-forums/topic/connection-was-refused-by-otherside-61620-61621#post-12725 Tue, 04 Jun 2013 08:24:17 +0000 vs 12725@http://www.datastax.com/support-forums/ <p>Hi tupton/camp5gong,</p> <p> I am facing the same problem now. Were you able to resolve the issue?<br /> Can you tell me how do I open the port 61621 on my opsCenter machine to enable incoming traffic?</p> <p>Thanks,<br /> VS </p> http://www.datastax.com/support-forums/topic/connection-was-refused-by-otherside-61620-61621#post-6989 Wed, 17 Oct 2012 15:51:57 +0000 tupton 6989@http://www.datastax.com/support-forums/ <p>camp5gong,</p> <p>Here is a reference for the ports that opscenter and the agent use: <a href="http://www.datastax.com/docs/opscenter/reference_opsc" rel="nofollow">http://www.datastax.com/docs/opscenter/reference_opsc</a></p> <p>The agent listens on 61621 for traffic from opscenter, and it appears that port is not open on your nodes with agents running. Can you open that port to your opscenter machine and see if that works? </p> http://www.datastax.com/support-forums/topic/connection-was-refused-by-otherside-61620-61621#post-6953 Mon, 15 Oct 2012 12:17:02 +0000 camp5gong 6953@http://www.datastax.com/support-forums/ <p>#OpsCenter<br /> root@ip-OpsCenter:/etc/opscenter# netstat -al | grep 6162<br /> tcp 0 0 *:61620 *:* LISTEN<br /> tcp 0 0 ip-OpsCenter:61620 ip-agent2_ip:57996 ESTABLISHED<br /> tcp 0 0 ip-OpsCenter:61620 ip-agent1_ip:36854 ESTABLISHED</p> <p># ip-agent1_ip<br /> root@ip-agent1_ip:/home/chaton/cass/conf# netstat -al | grep 6162<br /> tcp6 0 0 ip-agent1:36854 ip-OpsCenter:61620 ESTABLISHED</p> <p># ip-agent2_ip<br /> root@ip-agent2_ip:/var/lib/opscenter-agent/conf# netstat -al | grep 6162<br /> tcp6 0 0 ip-agent2_ip:57996 ip-OpsCenter:61620 ESTABLISHED </p> http://www.datastax.com/support-forums/topic/connection-was-refused-by-otherside-61620-61621#post-6952 Mon, 15 Oct 2012 10:59:39 +0000 camp5gong 6952@http://www.datastax.com/support-forums/ <p>Hello, I hava a question about those ports, 61620, 61621.</p> <p># opscenterd.conf<br /> [agents]<br /> ssh_port = 2022<br /> use_ssl = false<br /> https_port = 61621<br /> incoming_port = 61620</p> <p>#address.xml<br /> stomp_interface: "10.128.4.12"<br /> stomp_port: 61620</p> <p>2012-10-15 10:42:16+0000 [] DEBUG: Average opscenterd CPU usage: 0.10%, memory usage: 35 MB<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] DEBUG: Getting nodelist over thrift<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] DEBUG: Collecting topology info for node agent1_ip<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] DEBUG: Performing HTTP request: <a href="http://agent1_ip:61621/cluster/datacenter?node_ip=agent1_ip" rel="nofollow">http://agent1_ip:61621/cluster/datacenter?node_ip=agent1_ip</a>, body: {}<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] DEBUG: Collecting topology info for node agent2_ip<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] DEBUG: Performing HTTP request: <a href="http://agent2_ip:61621/cluster/datacenter?node_ip=agent2_ip" rel="nofollow">http://agent2_ip:61621/cluster/datacenter?node_ip=agent2_ip</a>, body: {}<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] WARN: HTTP request <a href="http://agent1_ip:61621/cluster/datacenter?node_ip=agent1_ip" rel="nofollow">http://agent1_ip:61621/cluster/datacenter?node_ip=agent1_ip</a> failed: Connection was refused by other side: 111: Connection refused.<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] WARN: Unable to collect datacenter, rack information: Failed query to <a href="http://agent1_ip:61621/cluster/datacenter?node_ip=agent1_ip" rel="nofollow">http://agent1_ip:61621/cluster/datacenter?node_ip=agent1_ip</a> : Connection was refused by other side: 111: Connection refused.<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] WARN: HTTP request <a href="http://agent2_ip:61621/cluster/datacenter?node_ip=agent2_ip" rel="nofollow">http://agent2_ip:61621/cluster/datacenter?node_ip=agent2_ip</a> failed: Connection was refused by other side: 111: Connection refused.<br /> 2012-10-15 10:42:16+0000 [OPSCENTER_TEST] WARN: Unable to collect datacenter, rack information: Failed query to <a href="http://agent2_ip:61621/cluster/datacenter?node_ip=agent2_ip" rel="nofollow">http://agent2_ip:61621/cluster/datacenter?node_ip=agent2_ip</a> : Connection was refused by other side: 111: Connection refused. </p>
