Environment

Cause

Permissions needed to perform network operations for non root user are not set.

Resolution

Perform the following operation on the system (the path may need to be adjusted):

   sudo setcap cap_net_raw+eip /opt/nimsoft/probes/network/net_connect/net_connect

To verify it has been set:

   getcap /opt/nimsoft/probes/network/net_connect/net_connect

Deactivate and activate the net_connect probe.
