| Packet socket sample |
| #################### |
| |
| Overview |
| ******** |
| |
| This sample is a simple packet socket application showing usage |
| of packet sockets over Ethernet. The sample prints every packet |
| received, and sends a dummy packet every 5 seconds. |
| The Zephyr network subsystem does not touch any of the headers |
| (L2, L3, etc.). |
| |
| Building and Running |
| ******************** |
| |
| When the application is run, it opens a packet socket and prints |
| the length of the packet it receives. After that it sends a dummy |
| packet every 5 seconds. You can use Wireshark to observe these |
| sent and received packets. |
| |
| See the `net-tools`_ project for more details. |
| |
| This sample can be built and executed on QEMU as described |
| in :ref:`networking_with_qemu`. |
