There are various connect functions that allow connections through either TCP or UNIXstream. Determine which is appropriate for you by evaluating whether you are connecting to the same machine or a different machine. If the agent and the subagent are using the same machine, use the UNIXstream connection for better performance. If the agent and the subagent are using different machines, you must use the TCP connection. There are two connect processing parameters:

• Hostname—name or the IP address of the agent
• Community name—password that allows the DPI connect function to obtain the port (for TCP) or path name (for UNIX) that allows the socket connect to occur.
