Discoverability

Sometimes an embedded device should be automatically discoverable in a network. For instance, automatic discovery allows service technicians to scan for devices and users to find and access devices more easily.

To facility discovery, Avahi can be used. To install Avahi, you can use the Avahi Recipe available in the rugpi-extra repository.

Installing Avahi makes it possible to reach the system under the local domain name <hostname>.local in the local network via Multicast DNS. As a result, it is easy to access the Raspberry Pi simply by entering its hostname followed by .local, e.g., in the navigation bar of a browser. In addition, the recipe allows making SSH, SFTP, and an HTTP interface discoverable via DNS-SD. To this end, use the recipe's parameters.
