TCP/IP

This configures, tests, and debugs TCP/IP connections.

hcitcptest is run from the command line and helps debug TCP/IP interfaces.

In Windows, Start > Programs > Cloverleaf Integration Services 6.x > Tools > TCPIP test starts the TCP/IP Test stand-alone GUI.

An external interface is a system or device that produces information for translation by the system or receives information produced by a system translation. Essentially, it is any physical device that is connected to the system hub. In terms of the system, there is one protocol thread per external interface.

Use the Network Configurator to build external interfaces.

The connection from the system to an external interface or device is a basic concept. The process of establishing connectivity and verifying the protocol is a challenging aspect of the network.

The primary reason for simulating the external interfaces is that the physical device might not be accessible for testing purposes. It also isolates any protocol issues.

In an effort to better isolate potential problems when dealing with external interfaces or devices, use a step-wise approach to verifying the connection protocol. The tool for verifying external interfaces is hcitcptest, which permits a manual interface to a connection.
