NANOG 85 Hackathon Call for Projects
by Valerie Wittkop 07 Apr '22

07 Apr '22

We need you! The NANOG Hackathon Committee is calling for project developers/maintainers to participate in the NANOG 85 Hackathon <https://www.nanog.org/events/nanog-85-hackathon/>. Wednesday, May 25, 2022 - Intro/Tutorial/Team Formation (via Zoom) Saturday + Sunday, June 4-5, 2022 - Hacking (via Zoom and/or in Montréal) An essential part of NANOG conferences, our Hackathons are designed to be both fun and engaging, as well as provide a platform that builds community and fosters greater networking and programming knowledge. NANOG Hackathons are hands-on, and educational at their core — directly supporting the most critical aspects of our mission. All levels are welcome to participate, and as always, Hackathon registration <https://www.nanog.org/events/nanog-85-hackathon/registration/> is free. Theme: Projects that Make a Difference The NANOG 85 Hackathon will focus on the theme of making tools work better for ordinary users. For this Hackathon, we are looking to expand the reach of the event to bring in non-developers who have an itch to get something fixed. So this is your opportunity to work with other community members to fix that itch and make life better for everyone. The improvements can include better tutorials, documentation, cookie-cutter templates that people can build on when accessing an API - in short, stuff that you would like to see that enables better use of the tools you use or want to use. Of course, we will welcome our usual range of project proposals if you want to dive deep into the code and hack in a communal environment, so send in those proposals as well. We are asking those who wish to bring a project be prepared to generally cover the items listed here. - Provide an intro/mini-tutorial on the skills needed to successfully hack on said project - Use time between the intro (May 25th) and the Hackathon (June 4-5) to be available for introductions and general questions relating to the project - Create a “ReadMe” file or webpage with the following information - Languages used in the project - Good first issues (if using GitHub on the project) - How to set-up/run tests in the development environment - How to use sandbox environment (if you have one) - Documentation updates/issues that need review/correcting In exchange for your work, NANOG will offer you a complimentary registration for NANOG 85 taking place in Montréal June 6-8, 2022. Learn more about the Hackathon schedule here: https://www.nanog.org/events/nanog-85-hackathon/ If you are interested in bringing a project to the NANOG 85 Hackathon, please send a message to hackathon-support(a)nanog.org. We look forward to working with you! -- *Valerie Wittkop* Program DirectorOn behalf of the NANOG Hackathon Committee

IP Multicast Persistent Duplicate Packet Issue
by Roman Islam 06 Apr '22

06 Apr '22

Hi Everyone, Has anyone experienced a TETRA Radio application issue if underlying IP multicast transport sends persistent duplicate packets? Here is my scenario as below: PIM is running on the MPLS L3 VPN environment. C multicast is running on a single VRF (TETRA) only. Source is running behind a dual home PE. HSRP, PIM DR path is via PE1 to the source. Anycast RP is configured with PE1 & PE2. On the receiver side there is a single PE. When I check (S,G) route on the receiver side PE default MDT is working as expected. After the threshold exceeds it switches to the data MDT. PIM Assert mechanism winner is PE2 though (Since PE 2 has the highest IP and source is behind dual home PE with equal cost I guess). Can this be a reason for persistent duplicate multicast packets at the receiver side; since the assert winner is PE2 but HSRP, PIM DR path is via PE1 to the source? If this is the case is there any way to manually configure the assert winner to PE1? Roman

Hi, Bill: 0) Thanks for bringing up the NANOG posting guideline. We now have something tangible to discuss. 1) Section 6. looks most relevant. So, I copy and paste it below for our discussion: A. 6.1.1. "... > relevant excerpt 1 response to excerpt 1 ... ": This seems to be what I have been doing, except maybe how to interpret the keyword "excerpt". Perhaps you are expecting me to cite more text from the message that I am responding to, such as a complete paragraph, instead of only a short phrase or two? If so, I certainly will be glad to do so. B. On the other hand, the leading sentence "When posting to the NANOG list please avoid: Top-posting, i.e., putting your reply right on top of the message you're responding to, ... " seems to discourage threading the messages (keeping a long tail of the earlier texts)? Perhaps there is some kind of optimal trade-off between how much each of these two should be included in a message? 2) The two URLs are kind of odd: A. The first URL led me to a blank webpage. B. The second URL led me to a list of Q&A's that seem to be more humorous than instructive. *************** *6. Posting Conventions* 1. *Format* When posting to the NANOG list please avoid: 1. Top-posting, i.e., putting your reply right on top of the message you're responding to, rather than quoting and responding as follows: > relevant excerpt 1 response to excerpt > relevant excerpt 2 response to excerpt > relevant excerpt 3 response to excerpt 2. Using non-standard methods of quoting prior text; 3. Failing to quote, or to snip, as appropriate; 4. Sending in HTML or other non-standard attachment formats; 5. Starting or participating in flame wars. The linux-kernel mailing list FAQ provides detailed instructions for* quoting prior text*: http://www.tux.org/lkml/#s3-9 "Dear Emily Postnews" at http://www.templetons.com/brad/emily.html makes lots of good suggestions about *signatures* and other items of interest. *************** Please review and advise.

Re: Enhance CG-NAT Re: V6 still not supported

Hi, Ant: 1) As I Cc:'ed you, I attempted to contact the author of the IPv4+ draft a few days ago to offer my reading of his work. I have not heard any response. In short, I believe that IPv4+ is paraphrasing the scheme of the unsuccessful RFC1385 that EzIP Draft cited as Informative Reference [12]. -- meaning that EzIP has avoided the trap of such approach. 2) I went back to earlier versions of the IPv4+ drafts and discovered a surprising trend. That is, through all eight revisions, there has been hardly any actual write-up text changes! It appears that the author is just keeping the six-months-timer ticking. 3) Since you indicated that IPv4+ was reported to NANOG, maybe you could retrieve that thread and check with the author about what is the status? 4) "Have you approached any vendors about the feasibility of IP Options being used for switching at line rate in silicon? ": No. For the first phase of implementing EzIP, the configuration is called RAN (Regional Area Network). It is essentially a numbering plan enhancement to CG-NAT. There is no change to the basic IPv4 Header. The only engineering effort is "disabling the program code that has been disabling the use of the 240/4 netblock", followed by retiring the NAT function. So that CG-NAT can operate as simple routers, by having the look-up state-tables capability as backup. 5) In the long run, yes, processing of the Option Word needs be considered and ideally be implemented in silicon to achieve the line rate switching. Many claim, however, such end-to-end connectivity is not needed according to the current trend, which is primarily Server / Client model by CDN business. So, EzIP is actually a forward looking two stage scheme. We can focus on the first phase for now to relieve the underlying issues. There will be plenty of lead time to upgrade the silicon when the demand for end-to-end connectivity begins to build up. 6) " ... but your replies are practically illegible because of formatting. ... ": I am still learning the proper eMail etiquette on NANOG. Could you please echo back some of my writings as you received? So that I can see what they got transformed to.

Lumen / Level3 filtergen is trimming these routes now. Don't bother trying to query filtergen.level3.net currently; server is full. Small AS cone does not equal small societal footprint & impact. While I appreciate the intention upthread of proxy registering at ATLDB, it really just distracted from finding the root issue.

Gmail (thus Nanog) rejecting ipv6 email
by Dan Mahoney (Gushi) 05 Apr '22

05 Apr '22

I've been seeing a long thread about why ipv6 adoption isn't there yet. This is half a "paging someone with clue" post and half a "...really, guys?" Picard-facepalm post. I just (earlier this week) had to disable ipv6 outbound on one of $dayjob's MX servers, because Gmail, who hosts nanog.org, was rejecting our mail due to "our domain's very low reputation". (In this parlance, "Very Low" is an actual indicative metric.) Dayjob is the people who make BIND and run a root DNS server. Totally disreputable, I'm sure. I don't see anything indicating this in our postmaster tools. I am certain this action is happening completely transparently and invisibly to NANOG, unless others have complained. Whatever UI google gives them to manage their domain will not show this. There are no logs they can grep. I'm told that "gmail's filters for ipv6 are way tighter than ipv4" but that's from a non-canonical source. If this is the case, it does very little to further ipv6 adoption, that's for sure. I've posted over on mailop, and was given a contact (Brandon), but haven't heard back. Gmail's a black box. I've reached out to a few other people, but if anyone here can loan a bat-phone, please let me know. I'm loathe to randomly re-enable ipv6 without contact from someone saying why this happened, and how it's been fixed. -Dan (Who actually operates my own network) -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC FB: fb.com/DanielMahoneyIV LI: linkedin.com/in/gushi Site: http://www.gushi.org ---------------------------
