Pybatfish - Open source network validation SDK
by Ratul Mahajan 22 Aug '18

22 Aug '18

Hey, folks - Since many of you build and use tools for network validation, I wanted to share a quick announcement. We just released Pybatfish <http://github.com/batfish/pybatfish>, a Python SDK for Batfish. As you may know, Batfish is an open source framework for deep (semantic) validation in multi-vendor networks (which we presented at NANOG65 <https://www.youtube.com/watch?v=sKApcGY6MxQ>). Pybatfish will make it easy for you to leverage the power of Batfish and to embed validation in your testing/automation pipeline. Getting started is easy: Check out the Jupyter notebooks on our github page (or corresponding videos <https://www.youtube.com/channel/UCA-OUW_3IOt9U_s60KvmJYA>), or ping us on Slack <https://join.slack.com/t/batfish-org/shared_invite/enQtMzA0Nzg2OTAzNzQ1LTUx…> . Cheers.

2nd call for presentations RIPE 77
by Benno Overeinder 20 Aug '18

20 Aug '18

Dear colleagues, Please note the approaching deadline of *26 August 2018* for RIPE 77 plenary programme submissions. You can find the CFP for RIPE 77 below or at https://ripe77.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings, see the "Speakers" paragraph in CFP for more information. Kind regards, Benno Overeinder RIPE PC Chair https://ripe77.ripe.net/ripe-pc/ -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. *RIPE 77 will take place from 15-19 October in Amsterdam, The Netherlands* The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 77. See the full descriptions of the different presentation formats: https://ripe77.ripe.net/submit-topic/presentation-formats/ Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than *26 August 2018*. Proposals submitted after this date will be considered depending on the slots still available in the programme. The PC is looking for presentations covering the topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Connected Things (aka. Internet of Things - IoT) ---- Speakers ---- Presenters, RIPE Working Group Chairs and the RIPE Programme Committee are required to cover their own costs to attend a RIPE Meeting (meeting ticket, travel and accommodation). We have various ticket options available depending on your needs. In extraordinary circumstances, the RIPE Chair can waive the meeting fee for presenters. These requests are dealt with on a case-by-case basis via pc(a)ripe.net. Also note that, on an individual basis, participants can apply for a RIPE Fellowship or RACI to develop their professional or academic career. For more information, please visit: https://www.ripe.net/participate/ripe/ripe-fellowship https://www.ripe.net/participate/ripe/raci ---- Submissions ---- Presenters should be clear on whether they wish to submit a presentation for a plenary or working group (WG) session. At present, most working groups will solicit policy proposals, discussion points or other content directly via their mailing lists. If you’re not sure what kind of session you should be presenting at, please visit: https://ripe77.ripe.net/plenary-or-wg/ RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and should not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour (during evening sessions) - Lightning talks: 10 minutes in total for both the presentation and any discussion The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe77.ripe.net/submit-topic/ - Lightning talks should also be submitted using the meeting submission system (https://ripe77.ripe.net/submit-topic/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice, in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. ---- Diversity and Inclusion - On-Site Childcare and the RIPE Meeting Code of Conduct ---- Did you know that RIPE Meetings now have on-site childcare? You can reserve a spot for your child (age 6 months – 10 years) during the registration process for the meeting. Registrations for RIPE 77 will open mid-July. Childcare places are limited, so please be quick to reserve a spot for your child! Read about the experiences of our next generation of engineers at: https://labs.ripe.net/Members/agowland/ripe-meeting-diversity-efforts-on-si… Ensuring that RIPE Meeting values are upheld and that attendees experience a professional, respectful and safe meeting is a priority. Please do read the RIPE Meeting Code of Conduct: https://www.ripe.net/participate/meetings/ripe-meetings/ripe-meeting-code-o… --- If you have any questions or requests concerning content submissions, please email pc(a)ripe.net.

tcp md5 bgp attacks?
by Randy Bush 19 Aug '18

19 Aug '18

so we started to wonder if, since we started protecting our bgp sessions with md5 (in the 1990s), are there still folk trying to attack? we were unable to find bgp mib counters. there are igp interface counters, but that was not our immediate interest. we did find that md5 failures are logged. looking at my logs for a few years, i find essentially nothing; two 'attackers,' one my own ibgp peer, and one that noted evildoer rob thomas, bgprs01.ord08.cymru.com. we would be interested in data from others. note that we are neither contemplating nor suggesting removing md5 from [y]our bgp sessions. randy

Web UI DHCP Option 82
by Mike Hammett 18 Aug '18

18 Aug '18

Are there any web interfaces out there for DHCP servers that accommodate management of DHCP option 82 configs? Neither webmin nor Glass seem to handle ISC's agent.circuit-id outside of presenting the raw config file. I can do that just fine in nano, but I'm looking at something more user-friendly so I'm not the only one that can work on it. I'm also cheap, so not looking at Infoblox or anything like that. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Inbound Call Issues
by Will Duquette 17 Aug '18

17 Aug '18

Has anyone had issues reported over the last few weeks from customers with inbound calls in the Northeast reporting the following: 1. Long call setup 2. No ring back or very delayed ring back (Post Dial Delay) 3. Delayed audio in calls. Persons on each end maybe talking over each other. 4. Multiple call logs showing up for a single call in logs. We have been engaging multiple providers (CCI, Spectrum, Windstream and Onvoy) and have been making some progress but are looking to see if anyone else is experiencing the same issues. Thanks, -- Will Duquette *Network Engineer II*GWI *Office:* 207-602-1228 *Cell:* 207-590-2084 *Fax:* 207-282-5036 www.gwi.net

A lot of very useful netflow based analytical tools in an easy UI.

I built a Docker image to make it easy to install FlowViewer. I also factored the FlowViewer source files to make it easier to install in a Docker instance. I have no opinion whether Docker would be a good solution for a high performance Netflow collector. However, this Dockerfile makes it easy (~15 minutes) to get started with testing. Grab the files from my github repo's: https://github.com/richb-hanover/FlowViewer https://github.com/richb-hanover/docker-silk-flowviewer I also made a couple other Docker instances of Netflow tools. They're mentioned in my blog: http://richb-hanover.com/netflow-collectors-for-home-networks/ Enjoy! Rich Brown Blueberry Hill Software
