Utility: packet acknowledger

  1. Introduction

The packet acknowledger is a simple helper program listening on a single UDP port and responding to PUSH_DATA datagrams with PUSH_ACK, and to PULL_DATA datagrams with PULL_ACK.

Informations about the datagrams received and the answers send are display on screen to help communication debugging.

Packets not following the protocol detailed in the PROTOCOL.TXT document in the basic_pkt_fwt directory are ignored.

  1. Dependencies

This program follows the v1.1 version of the gateway-to-server protocol.

  1. Usage

Start the program with the port number as first and only argument.

To stop the application, press Ctrl+C.
