Here is the agenda for the OpenSource-WG at the upcoming RIPE 73: A. Administrative Matters (Working Group Chairs) [5..10 mins] . Welcome . finalize agenda . approval of minutes from previous WG meeting(s) . review of action list B. PCAP BGP Parser [15 mins] Network operations increasingly relies on tools and features to perform in-depth analysis of Internet routing behavior to optimize traffic flows or dissect DDoS attacks. In particular, IXPs commonly operate software routers such as BIRD or Quagga as BGP route servers. However, the implemented data processing features and tools are somewhat limited. BIRD does not support continues BGP exports, MRT dumps allow a post-best-path-selection view only, and the tshark BGP filtering capabilities are limited, just to name a few. In this talk we present a TCP dump BGP parser to overcome these limitations. The raw packets can be captured with tcpdump at the network interface of any software router and either be processed as a live-stream or stored and analyzed subsequently. For a post mortem analysis the BGP parser comes with a rich set of filters and export formats to meet the desired level of granularity. The presentation will showcase some compelling examples. Moreover, the tool can be extended as favored since it is available as open source project at GitHub. (Christoph Dietzel, DE-CIX) C. DHCPKit presentation [20 mins] DHCPKit is a fully customisable DHCPv6 server. It was initially written for ISPs to provision FttH customers, but because of it's flexible architecture it can be used in almost any setup. Behaviour can be customised with simple plugins. Some examples are an Apache Kafka based distributed looking glass, simple CSV-file based prefix delegation and rate limiting. This presentation will give an introduction to DHCPKit and show how it can be customised. (Sander Steffann) D. Automated management of Continuous Integration Jobs When you start testing your software using continuous integration you might start small where manual management is easy. But when you grow bigger it becomes tedious and there comes point in time when you have to do it automatically. In this presentation I will look at different approaches how to use your CI in automated way using reuseable configuration to describe a CI jobs on top of several Open Source CI tools: Jenkins Job Builder // Build Bot // Gitlab CI. (Ondřej Surý, CZ.NIC) E. OpenSource Lightening Updates [20 mins] These are short updates on different relevant OpenSource projects. They should be 5 mins (preferably) with a maximum of 10 mins (if space allows). No formal submission required ahead of RIPE, but please send a short message to opensource-wg-chairs@ripe.net by noon on Tuesday during the RIPE if you want to present an update. Selection of talks are done on Tuesday afternoon. Regards, Martin Winter & Ondrej Filip OpenSource-WG Chairs
