Meeting Materials

Participant Preparation and Prerequisites

  • Choosing a Project
    • Champions will have table signs on the center of their table identifying their project and be available to answer questions at the start and throughout the hackathon
    • Optionally, champions may create and display posters on flip charts with additional information on their project
    • Details on each project and links to additional information for each project are in this wiki in the "Projects Included in Hackathon" section
    • Familiarity with technology area(s) in which you plan to participate will certainly help
    • It is perfectly fine, even encouraged, to work on multiple projects
  • Development Environment
    • Bring a laptop on which you are comfortable developing software
    • Some projects may require installing additional software or make use of VMs
    • Installing and becoming familiar with VirtualBox, Vagrant, or something similar will help
    • Note to champions: if planning to make use of VMs, please bring on USB drives to make available to others as download times can be painful
    • Specific coding languages are called out by some projects (e.g. Python, Java), but this is heavily dependent on the project(s) you choose
  • Network
    • Wireless access to the IETF network will be provided, and from there to the outside world
    • Wired access to the IETF network is available by request only
    • If you have additional requirements, email Charles Eckel: eckelcu@
  • Sharing Code
    • Git/GitHub is commonly used for open source projects. Familiarizing yourself with it is recommended.
    • An online tutorial is available here: Git Tutorial
    • IETF Hackathon GitHub Org
      • If you would like to have your project/code hosted here, send your GitHub ID and the name of your project via email to Charles Eckel: eckelcu@
  • Training Materials
  • Champions for each technology are encouraged to share any other things they think would be helpful in preparation for the hackathon
  • Project Presentations
    • All teams have the opportunity to present what they did on Sunday afternoon at the end of the hackathon
      • is for IETF hackathon participants to upload their hackathon project presentations
      • You must be a member of the IETF-Hackathon GitHub org to upload a new presentation or update/replace an existing presentation
      • To be added as a member, email Charles Eckel: eckelcu@ your GitHub ID at your earliest convenience
      • DO NOT WAIT until just before hackathon project presentations start or your request may be lost in the chaos

Remote participation

  • Participating in person is preferred, but we understand not everyone can travel. If you want to participate remotely, please contact the champion(s) of the project to determine how best to coordinate.
  • Jabber room:
  • Meetecho:

IPR and Code Contribution Guideline

All hackathon participants are free to work on any code. The rules regarding that code are what each participant's organization and/or open source project says they are. The code itself is not an IETF Contribution. However, discussions, presentations, demos, etc., during the hackathon are IETF Contributions (similar to Contributions made in working group meetings). Thus, the usual IETF policies apply to these Contributions, including copyright, license, and IPR disclosure rules.

  • Champion(s)
    • Aleksi Peltonen <aleksi.peltonen at>
    • Eduardo Inglés Sánchez <eduardo.ingles at>
  • Project(s)
    • EAP-NOOB is an EAP method where the authentication is based on a user-assisted out-of-band (OOB) channel between the server and peer.
    • It is a generic bootstrapping solution for Internet-of-Things devices which have no pre-configured authentication credentials and which are not yet registered on the authentication server. Consider devices you just bought or borrowed.
    • EAP-NOOB draft:
    • EAP-NOOB Implementation:
    • During the hackathon, we plan to work on the following:
      • Bug fixes
      • New OOB channels such as NFC and audio
      • Testing of new Reconnect Exchange


  • Champion(s)
  • Petr Špaček <petr.spacek at nic dot cz>
  • Project(s)
    • Common configuration interface for DNS - YANG. Cross DNS server manageability may significantly benefit from alignment on some baseline formal modeling approach. The combo if NETCONF protocol with YANG modeling was designed and in the meantime also is proven to work well in many configuration contexts - and might prove beneficial also for management of DNS servers and/or services. The hackathon project provides a prove of the concept
    • For more details, hackathon results summary and contact to the contributors please see IETF_104_hackathon_DNS%20-comon-config-dns-yang-v12.pdf
  • DNSTAP over CBOR. Today DNSTAP messages are delivered using protobuf encapsulated over fstrm, this project will try to use CBOR (RFC 7049) instead of protobuf but still use fstrm for the encapsulation and implement this in both sending (authoritative, resolver) and receiving (dnscap, dsc etc) software. Gist of CDDL example:
  • Brainstorm/hack around DNSTAP and usage of fstrm, current common implementation is that the DNS server software connect out to a fstrm/DNSTAP listener, would also be nice to be able to connect to the DNS server and get the DNSTAP when needed

  • Champions
    • Ted Lemon <mellon>

  • Projects (this ambitious, and we probably won't do all of it, but these would all be good things to work on if there is interest):
    • Turnkey homenet build of OpenWRT
    • If the Turris folks are down, it would be nice if they could join us and make it work in Turris OS as well.
    • Homenet-wide service discovery using the DNSSD Discovery proxy we’ve been working on, which is fully functional at this point.
    • Support for DNSSD SRP (this would involve finishing the SRP gateway I’ve been working on, and getting it to update Unbound or BIND).
    • Joining constrained-network edge routers to homenet routing and service discovery infrastructure
    • MUD support for devices that are not on a separate link, but are isolated from nodes that don’t have permission to talk to them. This should be doable in OpenWRT.
    • Automatic IKEv2 tunnels on OpenWRT that use the new split DNS stuff being published in IPSECME to allow us to serve to VPN clients.

    • At this Hackathon, in order to save precious time, we will not focus on live LPWAN connectivity. Instead, we will exchange SCHC messages over UDP, allowing easy remote participation including remote testing between participants.
    • on Sunday, we may still pull out a few pycoms and a LoRaWAN gateway, if Saturday was productive.
    • The 4 actions points for this week-end:
      • clean up the GitHub? repos, notably the documentation. In general, make it easier for a newcomer to join the project and contribute.
      • test the last version of Ack-on-Error fragmentation. Add consistent, human-readable logs. Add scenarios with various parameter values.
      • reconverge between two versions of the compression code.
      • discuss fragmentation rules representation, implement.
