Description (partial)


The error message:
"global correlation update failed: openConnection: Caught IpAddrException badAddrString"
indicates that a DNS lookup failed when the sensor attempted to resolve the address of a SensorBase Network update server.  This error message is not descriptive of the problem.


Occurs when global correlation inspection and/or reputation filtering is enabled and the sensor is unable to resolve a server's ip address due to an incorrect configuration of DNS or HTTP proxy or a network connectivity problem.
