ETCA: TCP/IP Connection Establish

This message is generated when a connection to a service running on a grid node is permitted.

CNDR Connection Direction Indicates whether the connection was opened by the grid node or by a remote host:

INBO: Connection initiated by a remote host, which connected to the grid node.

SVIP Destination Service Port The port to which the connection was established.
DAIP Destination IP Address The IP address to which the connection was established.
SAIP Source IP Address The IP address from which the connection was established.
CNID Connection Identifier The unique identifier of the connection.
RSLT Result Code Connection status:

SUCS: connection successfully established

This audit message means an incoming or outgoing TCP/IP connection was successfully established. This does not indicate the corresponding user was permitted to use the service — only that they were not rejected. Typically, each service implements additional authentication mechanisms specific to the service type (HTTP).

This message can be used to report on external hosts communicating with the system, and to correlate higher-level protocol messages back to the IP address initiating the activity. The “Connection Identifier” field allows correlation of audit messages related to actions performed during a session.
