The IETF ZeroConf working group and Apple both consider link-local addressing, especially IPv4 link-local addressing ( 169.254.0.0/16 addresses) to be part of ZeroConf/Bonjour, even though link-local addressing shipped years before the other two “legs of the stool”. Stuart Cheshire, who was the creator and is a primary maintainer of Rendezvous/Bonjour at Apple, who also co-chaired the IETF ZeroConf working group, and wrote the O’Reilly book on Zero Configuration Networking, has described Bonjour as a “three-legged stool” where the legs are: And I want to use Bonjour to help computers discover each other (computers are working in a local network). Every computer should run an Apache web server. I will try to formulate my question in a more clear way. Please ask questions if something is not clear in my question. These options seem to me to be the simplest! Since in these case, I do not need to use any additional libraries to communicate with Bonjour from a particular programming language. I have a special interest in accessing information about services from files, environment variables, or commands in the command line. Can Bonjour provide this information in some way? If it is the case, how exactly it works? How my program can get this information from Bonjour? Can my program read some files created by Bonjour containing the above-mentioned information? Can I use some commands in the command line to retrieve this information? Each service in the list should have a name, the IP address where it is running, and the port which is used by the application. In more detail, my application needs to have a list of services. For that, my application needs to know which devices/services are present in the network. How exactly my application can broadcast itself? Can I use the command line to register a service (so that all applications using Bonjour know that a new service appeared)?įurther, I would like to have an application that uses the IP network created by Bonjour. So, it is applications that broadcast themself (not computers) and it is not done automatically (application needs to broadcast themself explicitly). I mean that the applications running on the computers need to use Bonjour to broadcast themself. Or maybe a computer running Bonjour is not considered a service and it does not broadcast itself just because Bonjour is running on this computer. So, laptops (where Bonjour is running) build an IP network. Then, let's say, on some laptops I have Bonjour running, and then, as a consequence, these laptops assign IP addresses to them self automatically. Does it work in the following way? First I connect devices (for example laptops) physically so that they potentially can communicate with each other. But I thought that it not only "discovers devices on IP network" it also creates an IP network by assigning IP addresses to devices where Bonjour is running. Here I found out that Bonjour enables the automatic discovery of computers, devices, and services on IP networks.
First, what exactly Bonjour does (please read my guesses written below)?
