Hello, If one of you happens to be looking for a job or knows of someone looking for a job, my company is looking for an IT Engineer to be a part of the same team as I. You will find the job offer at the following URL : http://www-nexthink.s3.amazonaws.com/open_position/Nexthink-IT-Engineer-201… <http://www-nexthink.s3.amazonaws.com/open_position/Nexthink-IT-Engineer-201…> We’re basically looking for someone to be part of a multi-disciplinary IT team.

## SwiNOG #29 - 05.11.2015 - Agenda ##
by Simon Ryf 14 Oct '15

14 Oct '15

Hello dear SwiNOG community We finally have the agenda released for SwiNOG #29 on the Thursday 05.11.2015 on top of Gurten. Please register NOW. Registration closes in 2 weeks. https://register.swinog.ch/ Agenda http://www.swinog.ch/meetings/swinog29/agenda.asp Remote LAB | Urs Baumann (INS (HSR)) For our Cloud Infrastructure Bachelor module we have built a OpenStack environment. The students can execute their assessments in this environment. For a network course we have developed eight virtual pods. The participants can deploy the labs with a web deployment tool. In the presentation I will explain how this infrastructure works and what the challenges are. NETCONF/YANG: the orchestration revolution | Roque Gagliano (Cisco) Additionally, I do have a short demo that I can also do during my slot using a Cisco product that implements NETCONF/YANG. The idea is to show how to use YANG to model a simple L2VPN multi-vendor network. Let me know if a demo could be part of the presentation. Trends in DC architectures | Michael Pergament (Juniper) This slot will cover recent trends in DC architectures, discussing how Juniper approaches the challenges we face in access, aggregation/core and DC Interconnect. Specific use cases will be illustrated based on new platforms (QFX5xxx, QFX10k) representing universal building blocks for any type of DC architecture (MC-LAG, L2/L3 Fabric, EVPN/VXLAN, MPLS-based DC). SwissIX update | Ulf Kieber (SwissIX) SwissIX update UC - Trends & Challenges | Roland Mamie & Marco Stieger) (zebbra AG) Is the development process in Unified Communication already done (is UC dead?) or will there be new trends, challenges and innovations? We think so and want you to present possible trends and challenges in the further innovation of UC ... - Integration of UC with SDN - WebRTC (UC going to the browser) - Video - SECURITY - What is going to happen to the PSTN? - UC Monitoring - Do it the smart way (Demo) Sponsor slot (tbd) | tbd (Brocade) promised to be very technical ;-) Hacking Arista appliances for fun and profit | Romain Aviolat (Kudelski) it's about presenting an unusual setup that we designed for my company, we have special networking requirements for applications like 10Gb port-scanners, DOS-as-a-service, ... and our edge routers must be able to handle that kind of traffic. the 101 of 100G interoperability | Thomas Weible (FlexOptix) Self-explanatory (comment by Simon ;) Your cache DNS server also requires your attention | Nicolas Cartron (Efficient iP) Nowadays, most of the DDoS attacks making the news are targeted against Authoritative DNS servers. While those attacks are the easiest to realise, as Authoritative DNS servers are public, it is important not to lose track of Cache/Recursive servers (As few PCs or laptops within the LAN can take it down very easily if they are infested by botnets). This presentation will focus on the Recursive/Cache part of DNS Security, and will take as example a specific attack that EfficientIP has named "Sloth Domain Attack", to illustrate how vulnerable a Recursive/Cache server is, and how easy it is to bring it down. We will also discuss some ideas and the necessity to take a new approach when dealing with DNS attacks on Cache/Recursive servers. DevOps | André Keller (VSHN AG) Many SP's have Servers around running Tools and Services such as Rancid, Icinga, Cati, LibreNMS, DHCP, DNS, etc... Usually setup at some time and never patched. DevOps, Puppet, Configuration Managment in general can help to structure the chaos. With real life examples, Puppet Code and maybe a small demo we show you how it could be done. Social Event | Everyone (SwiNOG Community) Yeah - you all know this one ;-) never gets boring Looking so forward to seeing all of you !!!! Simon SwiNOG (hope you dont mind the HTML, let me know if youre reading it from telnet ;)

IPv6 Transition - Deep Dive into Map - IPv6 Council event on October 26
by Silvia Hagen 06 Oct '15

06 Oct '15

Dear Swinog Members The trend in the IPv6 market is to plan for an IPv6-centric migration to IPv6, meaning to reduce operational complexity by supporting IPv6-only as soon as possible. New transition mechanisms such as MAP-T and MAP-E support such scenarios. Martin Gysi from Swisscom is evaluating these. Today Swisscom successfully uses 6rd to tunnel IPv6 over their IPv4 backbone. With MAP they will tunnel IPv4 over an IPv6 backbone. We kindly invite you to participate in our next event and get a quick update on this new technology and latest trends: IPv6 Council Event: MAP Deep Dive, by Martin Gysi Swisscom Date: Monday October 26, 6pm to 9 pm (including networking apero) Details and Registration: https://www.digicomp.ch/events/it-professional-events/mapping-of-address-an… Martin will discuss their plans and tests, explain how MAP works and compare it with other available technologies. The event will take place at our partners location, at Digicomp at Limmatstrasse 50 in Zurich (next to main station). The event cost is CHF 20 at Abendkasse, free for Council members (IPv6 Experts). Look forward to seeing you Silvia Hagen Chair Swiss IPv6 Council Swiss IPv6 Council CH-8124 Maur +41 (0)44 887 62 10 www.swissipv6council.ch<http://www.swissipv6council.ch> http://twitter.com/IPv6CouncilCH ****************************************** IPv6 Business Conference, June 18, 2015, Zurich<http://www.ipv6conference.ch/> International Top Speakers, Unique Program Great Networking - watch out for the 2016 Conference ****************************************** Switzerland is in the Top 5 in IPv6 User Adoption We reached 21% in June 2015! *********************************** Our website is dual-stack - how about yours? ***********************************

Telco contacts in Germany
by Antoine Benkemoun-André 22 Sep '15

22 Sep '15

Hello, I know this is Swinog but we’ve recently encountered a case that we are having issues solving. We’re a Swiss company in the process of opening new offices in Frankfurt but are having a lot of problems trying to reach the local telcos in order to get quotes regarding the connectivity we can obtain at proposed locations. This is due to contact numbers not working from abroad and german-only speaking help desks. Yes, unfortunately I don’t speak german so that makes that much more complicated :-) So my question is, would someone here happen to have a contact for German providers such as Deutsche Telekom that I can contact from Switzerland ? If you can provide us this connectivity, we could be interested as well. We’re looking to get set up basic business-grade internet, preferably not a dedicated line, over fiber. Thank you in advance for your help, Antoine
