Your opinion on network analysis in the presence of uncertain events
by Vanbever Laurent 17 Jan '19

17 Jan '19

Hi NANOG, Networks evolve in uncertain environments. Links and devices randomly fail; external BGP announcements unpredictably appear/disappear leading to unforeseen traffic shifts; traffic demands vary, etc. Reasoning about network behaviors under such uncertainties is hard and yet essential to ensure Service Level Agreements. We're reaching out to the NANOG community as we (researchers) are trying to better understand the practical requirements behind "probabilistic" network reasoning. Some of our questions include: Are uncertain behaviors problematic? Do you care about such things at all? Are you already using tools to ensure the compliance of your network design under uncertainty? Are there any good? We designed a short anonymous survey to collect operators answers. It is composed of 14 optional questions, most of which (13/14) are closed-ended. It should take less than 10 minutes to complete. We expect the findings to help the research community in designing more powerful network analysis tools. Among others, we intend to present the aggregate results in a scientific article later this year. It would be *terrific* if you could help us out! Survey URL: https://goo.gl/forms/HdYNp3DkKkeEcexs2 Thanks much! Laurent Vanbever, ETH Zürich PS: It goes without saying that we would also be extremely grateful if you could forward this email to any operator you know and who may not read NANOG.

For more on the historical record, about 10 years after Randy, and from my own experience, this was briefly touched on this in a lightning talk at NANOG 41, "Explorations in the Public Peering Address Space". As part of a project looking at peering discovery, in the Q&A Louie Lee as I recall provided a partial answer to the announcement question raised. It might be worth watching the video for those interesting in this. Scroll to the bottom to see the deck and video here: <https://www.nanog.org/meetings/nanog41/agenda> John

Re: Network Speed Testing and Monitoring Platform
by rapier 16 Jan '19

Hello all, A colleague of mine pointed out this conversation to me. I'm not sure this is going to be the best solution to your problem but it may be helpful in some instances or for other people. At PSC we also have to deal with customers complaining of speed issues. Generally speaking this is all on the customer end but diagnosing these issues remotely, especially when people have limited access or skills, is huge time sink. It's compounded by the fact that many times we're trying to work over a number of different operating systems configurations and so forth. In order to cut down on that we created a service called TestRig2.0. In short, it dynamically generates an bootable ISO that automatically runs the host system through a number of network performance tests, packages the results, and send them back the network engineers via scp. The tests are run against the perfSonar infrastructure*. The reason why we use a bootable ISO is because we want to make sure that the tests are being conducted under a known good OS environment. Additionally, we can also limit the number of tests the users can run - either by restricting them to specific time frame (say 7 days) or a total number of runs. After that the ISO will no longer conduct the tests. If anyone is interested please take a look at https://testrig.psc.edu/ for more information. If you are interested in using the service let me know. Setting up an account is pretty easy but I'd like to work with people in the initial process. Thanks, Chris Rapier * Not all commodity users will have access to all of the perfSonar nodes so this is a part where some extra work might be required on the part of the engineer.

Service Provider NetFlow Collectors
by Erik Sundberg 16 Jan '19

16 Jan '19

Hi Nanog.... We are looking at replacing our Netflow collector. I am wonder what other service providers are using to collect netflow data off their Core and Edge Routers. Pros/Cons... What to watch out for any info would help. We are mainly looking to analyze the netflow data. Bonus if it does ddos detection and mitigation. We are looking at ManageEngine Netflow Analyzer PRTG Plixer - Scrutinizer PeakFlow Kentik Solarwinds NTA Thanks in advance...

I think that is essentially what the service does, but in a BGP feed and maintained for you, kind of like the bogons service. John

Call for Participation -- ICANN DNSSEC Workshop at ICANN64 Kobe, Japan
by Jacques Latour 16 Jan '19

16 Jan '19

Call for Participation -- ICANN DNSSEC Workshop at ICANN64 Kobe, Japan The DNSSEC Deployment Initiative and the Internet Society Deploy360 Programme, in cooperation with the ICANN Security and Stability Advisory Committee (SSAC), are planning a DNSSEC Workshop during the ICANN64 meeting held from 09-14 March 2019 in Kobe, Japan. The DNSSEC Workshop has been a part of ICANN meetings for several years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. For reference, the most recent session was held at the ICANN Annual General Meeting in Barcelona, Spain, on 24 October 2018. The presentations and transcripts are available at: https://63.schedule.icann.org/meetings/901549, and https://63.schedule.icann.org/meetings/901554, and https://63.schedule.icann.org/meetings/901555. At ICANN64 we are particularly interested in live demonstrations of uses of DNSSEC, DS automation or DANE. Examples might include: * DNSSEC automation and deployment using CDS, CDNSKEY, and CSYNC * DNSSEC/DANE validation in browsers and in applications * Secure email / email encryption using DNSSEC, OPENPGPKEY, or S/MIME * DNSSEC signing solutions and innovation (monitoring, managing, validation) * Tools for automating the generation of DNSSEC/DANE records * Extending DNSSEC/DANE with authentication, SSH, XMPP, SMTP, S/MIME or PGP/GPG and other protocols Our interest is to provide current examples of the state of development and to show real-world examples of how DNSSEC and DANE related innovation can be used to increase the overall security of the Internet. We are open to presentations and demonstrations related to any topic associated with DNSSEC and DANE. Examples of the types of topics we are seeking include: 1. DNSSEC Panel (Regional and Global) For this panel, we are seeking participation from those who have been involved in DNSSEC deployment in the region and also from those who have not deployed DNSSEC but who have a keen interest in the challenges and benefits of deployment. In particular, we will consider the following questions: Are you interested in reporting on DNSSEC validation of your ISPs? What can DNSSEC do for you? What doesn't it do? What are the internal tradeoffs to implementing DNSSEC? What did you learn in your deployment of DNSSEC? We are interested in presentations from both people involved with the signing of domains and people involved with the deployment of DNSSEC-validating DNS resolvers. 2. DS Automation We are looking at innovative ways to automate the parent child synchronization CDS / CDNSKEY and methods to bootstrap new or existing domains. We are also interested in development or plans related to CSYNC, which are aimed at keeping the glue up to date. We would like to hear from DNS Operators what their current thoughts on CDS/CDNSKEY automation are. 3. DNSSEC/DANE Support in the browsers We would be interested in hearing from browser develop what their plans are in terms of supporting DNSSEC/DANE validation. 4. DANE Automation For DNSSEC to reach massive deployment levels it is clear that a higher level of automation is required than is currently available. There also is strong interest for DANE usage within web transactions as well as for securing email and Voice-over-IP (VoIP). We are seeking presentations on topics such as: * How can the industry use DANE and other DNSSEC applications as a mechanism for creating a more secure Internet? * What tools, systems and services are available to help automate DNSSEC key management? * Can you provide an analysis of current tools/services and identify gaps? * What are some of the new and innovative uses of DANE and other DNSSEC applications in new areas or industries? * What tools and services are now available that can support DANE usage? We would be particularly interested in any live demonstrations of DNSSEC / DANE application automation and services. Demonstrations of new tools that make the setup of DNSSEC or DANE more automated would also be welcome. If you are interested in participating, please send a brief (1-2 sentence) description of your proposed presentation to dnssec-kobe(a)isoc.org' before ** 07 February 2019 ** We hope that you can join us. Thank you, Jacques Latour On behalf of the DNSSEC Workshop Program Committee: Jean Robert Hountomey, AfricaCERT Jacques Latour, .CA Russ Mundy, Parsons Ondřej Filip, CZ.NIC Yoshiro Yoneya, JPRS Dan York, Internet Society Mark Elkins, DNS/ZACR
