Typical last mile battery runtime (protecting against power cuts)
by Israel G. Lugo 06 Feb '23

06 Feb '23

Hi folks, At $day_job, I have a team of engineers who are oncall for critical services in the United Kingdom. For $reasons, the national power grid is announcing the possibility of rolling power cuts over the coming months. Right now it's "unlikely", but possible. If cuts do happen, it'll be 3+ hours, possibly several times/day. I'm looking at the cost/benefit of deploying small UPSes at people's homes, to protect their network access when oncall. Just to power the home router (+ONT if FTTP), and keep a charged laptop. I figure anything smallish should be enough for a few hours. Question is, how much battery runtime can I typically expect from ISPs' last mile infra. People will have a random mix of DSL, FTTP, DOCSIS. Another alternative is tethering with 4G. - For FTTP, I *think* (but am not sure) that the UK mostly uses PON, so guess it would be runtime of OLT and onwards - For DSL: runtime of DSLAM cabinet and onwards - For CATV: CMTS and onwards, maybe any active equipments in the HFC to the CPE? - For 4G: BSS and onwards Could anyone with last mile experience help with some ballpark figures? I.e. 15 min vs 8h or 8 days. Thank you, Israel

Looking for PoCs of rootlayer.net in Amsterdam. - AS51447 and in upstream providers
by irish.masms 06 Feb '23

06 Feb '23

Hello NANOG – longtime lurker, first time poster. I am requesting some assistance today with stopping a pervasive malware campaign being sent via email from multiple open proxies in the following IP blocks: 45.137.20.0 - 45.137.23.255 185.222.56.0 - 185.222.59.255 This IP space is assigned to rootlayer.net in Amsterdam. - AS51447 % Abuse contact for 'AS51447' is 'complain(a)rootlayer.net' All email has contained some sort of malicious code: ransomware, trojans, info sealers, and other various malware (some known and some brand new/not detected yet). The email content is spoofing various legitimate companies and banks. Since the beginning of the year when I became involved in a particular customer (elderly owner of a small business), we have been sending at least 5 complaints a day (one for each email) to complain(a)rootlayer.net, all reporting has been ignored. The most recent spoof & malware email was received at 16:33 PM PST 5 Feb 2023. Frankly, we have grown tired of filing abuse complaints into the black hole while an elderly gentleman is being targeted. I am not sure a contact at Rootlayer will be helpful at this point, but if someone has a contact it would be appreciated. More importantly, anyone have a contact at their upstream providers that may be able to beat down these criminal activities and Rootlayer? AS49981 - WorldStream B.V. AS49453 - Global Layer B.V. Any assistance would be greatly appreciated – thank you. Stay safe,

Does anyone know of a martin broadhurst?
by Dave Taht 05 Feb '23

05 Feb '23

He was apparently based in cambridge, but his site is down. Recently I stumbled across a series of articles by him that were lovingly illustrative, incredibly clearly well written, and appeared to use a C library that I don't have, covering a ton of fundamental algorithms that I would like to have in my toolkit, still, in C, because that is how I still think. I first found him whilst I was looking for a binpacking algorithm(s) and benchmarks for how well they performed on modern hardware. (I am trying to wedge 40m queues into 16 cores every 10ms) https://web.archive.org/web/20190530024749/http://www.martinbroadhurst.com/… And then I started reading the rest of his canon: Wow: https://web.archive.org/web/20190704202816/http://www.martinbroadhurst.com/… Stuff like (hit the archive per above to get these) http://www.martinbroadhurst.com/bellman-ford-algorithm-in-c.html really clean avl example: http://www.martinbroadhurst.com/avl-tree-in-c.html Anyway, given that the site is down, and he hasn´t posted anything in a year, I fear he has passed on. I did find an obituary that had about the right timing in 2021, and he had the neckbeard... Did/does anyone here know him? -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-69813666656… Dave Täht CEO, TekLibre, LLC

Contact for androidpolice.com
by Justin Krejci 03 Feb '23

03 Feb '23

Any contacts available that are responsible for androidpolice.com website hosting? Some of our IP space is not able to access their website. Other IP addresses of ours are working just fine. This appears to be some kind HTTP protocol layer issue but only affecting certain IP addresses. I am guessing it is some kind of web application firewall using outdated IP list data. Yes I know it is hosted at Amazon but every time I have tried to go through Amazon for support with websites they are hosting, they have 100% of the time told me they can't and/or won't help me with website hosting issues on their web platform; I have to go through their customer... which I don't have any good contact info for. I've tried reaching them on twitter, I've tried blindly emailing people listed on their website guessing their email addresses, etc. I have had zero response. Thanks! Justin

The local ILEC is doing that here - they use a spade to make a little slot in the customer's lawn and shove the cable in. If they have to cross a driveway or sidewalk, they dig out the expansion joint, shove the cable in and dump some cold patch in the gap. If they have to run multiple cables, they use a concrete saw to make the gap a bit wider. >There is microtrenched fiber in Vancouver BC >that is close to 20 years old now throughout the >downtown core that is nearly problem-free.

I'm familiar with the slightly more robust technique deployed by companies like Teraspan. I'm sure it works much better in the milder climate in BC. There are microtrench/VIF networks in Toronto and Ottawa as well. A few years ago, they were re-building one of the roads in the downtown core in Toronto, and the entire microtrenched network (mini handholes and all) had been lifted out of the street area and laid on the sidewalk, and protected with barriers and safety cones, etc. I just shook my head... -- Clayton Zekelman Managed Network Systems Inc.

It may. We don't use it. Too many freeze/thaw cycles each winter around here. It would get destroyed in a few years. Google tried to cheap out in Louisville... didn't quite work out https://www.theverge.com/2019/2/7/18215743/google-fiber-leaving-louisville-… - although that was even more sketchy than traditional microtrenching. As for rural, the business case becomes even more difficult when you're measuring kilometers per home passed instead of homes passed per kilometer...

Calgary Internet Exchange (YYCIX) deploys world's first ASPA-filtering Route Servers
by Job Snijders 02 Feb '23

02 Feb '23

CALGARY, CA-AB, Feb. 2, 2023 - The Calgary Internet Exchange (YYCIX) is thrilled to announce the deployment of the world's first ASPA-filtering Route Servers on a public peering fabric. The YYCIX Route Servers drop ASPA-invalid BGP routes in order to protect multilateral peers. ASPA (Autonomous System Provider Authorization) is a free RPKI-based technology for detection and mitigation of BGP route leaks. ASPA enables holders of Autonomous System identifiers to securely authorize one or more other Autonomous Systems as their upstream providers, in turn enabling Relying Parties (ISPs and IXPs) to use this cryptographically verifiable information to automatically stop improbable BGP paths from spreading through the global Internet routing system. ASPA complements other routing safety & security mechanisms: RPKI-ROV helps guard against fat-finger keyboard input errors, BGPsec helps establish strong assurances about BGP message authenticity & integrity, and finally ASPA helps stop route leaks. The key to worry-free routing operations will be to use all three in tandem. The ASPA specification is in active development as a freely accessible open standard through the collaborative Internet Engineering Task Force (IETF) process. YYCIX volunteers took on a leading role as early adopters (or 'lighthouse customer') to foster an environment in which real-world feedback can be contributed to the OpenBGPD developers and ASPA specification authors in the SIDROPS working group. Our hope is that many vendors and operators will embrace ASPA in the years to come. About YYCIX Internet Exchange Community Ltd =========================================== YYCIX is incorporated as a volunteer-driven tax-exempt non-profit corporation in Canada's third-largest municipality. YYCIX provides Alberta residents with direct access to local Internet content and helps increase the transfer speed of Internet communications between Alberta companies, friends, neighbors and family members. https://www.yycix.ca/ About OpenBGPD & Rpki-client ============================ Rpki-client is an freely usable and secure implementation of the RPKI for Relying Parties to facilitate validation of BGP announcements. The program queries the global RPKI repository system, verifies all cryptographic signatures, and outputs validated data in configuration formats suitable for OpenBGPD and StayRTR. https://www.rpki-client.org/ OpenBGPD is a free implementation of the IETF's Border Gateway Protocol suitable for ISPs and IXPs. OpenBGPD allows ordinary machines to be used as routers or route servers exchanging routes with other systems. ASPA-filtering in OpenBGPD was developed with support from the German Ministry for Economic Affairs & Climate Action's Sovereign Tech Fund, and the Route Server Support Foundation (RSSF - https://www.rssf.nl/) https://www.openbgpd.org/ OpenBGPD and rpki-client are part of the OpenBSD Project; and run on a wide variety of operating systems such as Debian, Ubuntu, Alpine, CentOS, Fedora, FreeBSD, Red Hat, and of course OpenBSD!

2FA Is Now Required on Your ARIN Online Account
by John Curran 01 Feb '23

01 Feb '23

NANOGers - Important reminder - As of today, access to ARIN Online now requires two-factor authentication on all ARIN Online accounts. See below for additional details. FYI, /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [arin-announce] 2FA Is Now Required on Your ARIN Online Account Date: February 1, 2023 at 11:10:47 AM EST To: "arin-announce(a)arin.net" <arin-announce(a)arin.net> As of today, 1 February 2023, ARIN now requires two-factor authentication (2FA) on all ARIN Online accounts. If you have yet to set up 2FA on your account, the next time you attempt to log in to your ARIN Online account, you will be redirected to the 2FA setup process and required to complete it before accessing your account. Customers can choose between Time-Based One-Time password (TOTP), SMS-based, and FIDO2/Passkey-enabled security key authentication methods. You can learn more about ARIN’s 2FA options, as well as guides to enabling these methods in your account, by visiting https://www.arin.net/2FA. Following a community consultation held in May 2022 (https://www.arin.net/participate/community/acsp/consultations/2022/2022-4/) ARIN chose to delay enforcement until February 2023 in order to provide our customers with a variety of options for authentication. By requiring 2FA for ARIN Online accounts, the ARIN community will have the benefit of stronger security for the registry, reduced risk of account fraud attempts, and increased confidence in the integrity of their ARIN resources. If you need assistance with the implementation of 2FA to your ARIN Online account, please contact our Registration Services Department from 7:00 AM – 7:00 PM ET, Monday through Friday, at +1.703.227.0660. Regards, John Curran President and CEO American Registry for Internet Numbers (ARIN) ------------- Helpful Resources: Need help setting up your 2FA? Visit https://www.arin.net/2fa to get started. You’ll find guides on enabling 2FA via an authenticator application, SMS, and security key hardware. We also provide information on how to receive and save your 2FA recovery codes, as well as what to do if you’ve lost access to your authenticator app, SMS phone number, or security key.
