Problem:  Subscribers running an application called "Data Feed Connector v1.0" are unable to establish a connection to the data feed host(s).

Reason:  The datafeed software is run thru java.exe.  Java has in the recent past experienced major security concerns.  And so for these reasons,  in a CNS VPS, java.exe does not by default have a firewall exception.  In 2003 OS, localhost traffic is allowed thru the firewall but the Java runtime is not compatible with this software without a manual upgrade.

Solution:  To make the software work in 2008/2012 OS, you simply need to add a firewall exception for the java.exe runtime OR allow all TCP traffic to/from IP address 127.0.0.1.  We recommend adding a firewall rule to allow source and destination IP address 127.0.0.1 (TCP) instead of allowing java.exe.

Win2003:  This software appears to require Java v8.  Java 8 is not officially supported on the 2003/XP platform, but it can be installed using the offline installer.  Download and run the offline installer in the VM.  Also select to uninstall the older version.

Specific details how to add a java firewall exception for 2008/2012 OS will be posted to this KB article shortly.  In the mean time, if you require assistance in configuring Java to allow Data Feed Connector to operate, please contact CNS Support.

NOTE:  VM's provisioned on/after January 25, 2015 should already be configured for Data Feed software.
