NCA (Network Configuration Application)
This process is in charge of connecting to and talking to the agents
resident on an HP Traffic Director. It also connects to and talks to the
dns server and the backed process. It is the NCA that updates
configuration information of the dns server every time user types a
commit command.
Some of the messages that are logged by the NCA are:

started.
This message is displayed when NCA tries to establish connection to
an agent on the specified port.
Aug 2 12:13:27 madagascar NCA: Connection
established to address 10.168.16.3 on port
1999.
When connection to an agent fails the following message is
displayed.
Aug 3 01:27:23 fox NCA: >>> Error: Connection
to address 10.168.16.27 on port 2037 has
failed.
Other major errors include the following:
