Mdns/Dns-Sd Tutorial
MDNS/DNS-SD TUTORIAL In this tutorial, we will describe how to use mDNS/DNS-SD on Raspberry Pi. mDNS/DNS-SD is a protocol for service discovery in a local area network. It is standardized under RFCs 6762 [1] and 6763[2]. The protocol is also known by the Bonjour trademark by Apple, or Zeroconf. On Linux, it is implemented in the avahi package. [1] http://tools.ietf.org/html/rfc6762 [2] http://tools.ietf.org/html/rfc6763 About mDNS/DNS-SD There are several freely available implementations of mDNS/DNS-SD: 1. avahi – Linux implementation (http://www.avahi.org/) 2. jmDNS – Java implementation (http://jmdns.sourceforge.net/) 3. Bonjour – MAC OS (installed by default) 4. Bonjour – Windows (https://support.apple.com/kb/DL999?locale=en_US) During this course, we will use only avahi. However, any of the aforementioned implementations are compatible. Avahi installation avahi is available as a package for Raspbian. Install it with: sudo apt-get install avahi-deamon avahi-utils Avahi usage avahi-daemon is the main process that takes care of proper operation of the protocol. It takes care of any configuration of the interfaces and network messaging. A user can control the deamon with command line utilities, or via D-Bus. In this document, we will describe the former option. For the latter one, please see http://www.avahi.org/wiki/Bindings. Publishing services avahi-publish-service is the command for publishing services. The syntax is: avahi-publish-service SERVICE-NAME _APPLICATION- PROTOCOL._TRANPOSRT-PROTOCOL PORT “DESCRIPTION” --sub SUBPROTOCOL For instance, the command: avahi-publish-service light _coap._udp 5683 “/mylight” --sub _floor1._sub._coap._udp will publish a service named ‘light’, which uses the CoAP protocol over UDP on port 5683. -

Open Printing Project Updates - 2019 Joint PWG/Open Printing Meeting - Lexington, KY Apr 16, 2019 Aveek Basu Till Kamppeter GSoC 2018 Projects ● Conversion of bannertopdf to QPDF: To make all filters in cups-filters which use Poppler only use the standard API of Poppler and no unstable, unofficial APIs. ● Enhancements for ipptool: Write additional ipptool scripts for coverage of operations and attributes that are required by IPP Everywhere, but not yet tested in IPP Everywhere Self-Certification process. ● PWG Raster "ippdoclint" program: To have a tool that can take an input PWG Raster document file and check it’s structure and report any errors / warnings / issues with the document's structure or content. ● Content-oriented printer auto-selection: Cluster arbitrary collection of printers (all available printers) into one queue with merged PPD with all options of all printers available. Depending on the document and which options the user sets the printer where the job gets printed is selected automatically. ● *Common Print Dialog Backends project: D-Bus interface to separate the print dialog GUI from the communication with the actual printing system (CUPS, Google Cloud Print, …) having each printing system being supported with a backend and these GUI-independent backends working with all print dialogs (GTK/GNOME, Qt/KDE, LibreOffice, …). (This project is partly complete) GSoC Project List for 2019 Upcoming Projects: ● Generic Framework to turn legacy drivers consisting of CUPS filters and PPDs into Printer Applications: Printer Applications are simple daemons which emulate a driverless IPP network printer on localhost, do the conversion of the print jobs into the printer's format, and send the job off to the printer. -
