Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com> |

.. _ipv4-autoconf-sample: IPv4 autoconf client application ################################ Overview ******** This sample application starts a IPv4 autoconf and self-assigns a random IPv4 address in the 169.254.0.0/16 range, it defends the IPv4 address and resolves IPv4 conflicts if multiple parties try to allocate an identical address. Requirements ************ - :ref:`networking_with_host` Building and Running ******************** These are instructions for how to use this sample application running on a :ref:`frdm_k64f` board to configure a link local IPv4 address and connect to a Linux host. Connect ethernet cable from a :ref:`Freedom-K64F board <frdm_k64f>` to a Linux host machine and check for new interfaces. Running Avahi client in Linux Host ================================== Assign a IPv4 link local address to the interface in the Linux system .. code-block:: console $ avahi-autoipd --force-bind -D eth0 FRDM_K64F ========= Build Zephyr the ``samples/net/ipv4_autoconf`` application using these steps: .. zephyr-app-commands:: :zephyr-app: samples/net/ipv4_autoconf :host-os: unix :board: frdm_k64f :goals: build flash :compact: Once IPv4 LL has completed probing and announcement, details are shown like this: .. code-block:: console $ sudo screen /dev/ttyACM0 115200 .. code-block:: console [ipv4ll] [INF] main: Run ipv4 autoconf client [ipv4ll] [INF] handler: Your address: 169.254.218.128 Note that the IP address may change at each self assignment. To verify the Zephyr application is running and has configured an IP address type: .. code-block:: console $ ping -I eth1 169.254.218.128
