Even without anycast, an ECMP shouldn't hash on the ECN bits. Doing so will split the flow over multiple paths; avoiding that is the whole point of doing the flow-based hashing in the first place. Anycast "only" turns a potential degradation of TCP performance into a hard failure... :) -Toke

DNSSEC & WIldcards
by Dennis Burgess 01 Feb '25

01 Feb '25

So have *.app.linktechs.net that I have been trying to get to work, we have DNSSEC on this, and its failing, but cannot for the life of me understand why. I think it may have something to do with proving it exists as a wildcard, but any DNSSEC experts want to take a stab at it ? Dennis Burgess

DNSSEC failing when querying zones under ca. randomly but only from some regions
by Adam Daniels 30 Jul '24

30 Jul '24

Subject says it all, and I’m in 500-mile email mystery here. Anybody want to take a guess what it could be? Synopsis: Queries to .ca zones randomly fail with a DNSSEC validation error but it appears to be region dependent and zone dependent. Anycast verifying resolvers seem most prone to trigger the failure mode. I can’t trigger it running a local verifying resolver (unbound). I tried raising this with CIRA on Friday morning, and have observed it since Wednesday, but nothing back from CIRA yet. Being geo-dependent, I’m guessing the resolver that’s shortest path to me might have an issue, but I can trigger it on multiple services usually (Google + CloudFlare at least) so I can’t see that being the issue. I can trigger this from the Google DNS Web page as well, but not reliably. I can trigger this on domains I am not authoritive for (random domains I found while browsing) but I’ll use two authoritive domains here. $ dig seattle.mediadrive.ca @8.8.8.8 ; <<>> DiG 9.10.6 <<>> seattle.mediadrive.ca ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 56149 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ; OPT=15: 00 07 45 78 70 69 72 65 64 20 52 52 53 49 47 20 66 6f 75 6e 64 20 66 6f 72 20 70 75 66 35 32 6b 70 68 36 75 30 71 35 67 68 73 69 6c 72 33 68 63 31 64 37 65 6c 62 61 68 67 33 2e 63 61 2f 6e 73 65 63 33 20 28 6b 65 79 74 61 67 3d 35 36 38 31 36 29 ("..Expired RRSIG found for puf52kph6u0q5ghsilr3hc1d7elbahg3.ca/nsec3 (keytag=56816)") ;; QUESTION SECTION: ;seattle.mediadrive.ca.

A single place for information relating to the deployment and usage of RPKI
by Christopher Hawker 29 Jul '24

29 Jul '24

Hello All, When it comes to RPKI, its deployment and usage, there is a fair bit of information available on the Internet. Each RIR has their own guides for creating ROAs, each router vendor and developer has their own guides for deploying route object validation on their devices and software, each Relying Party software developer has their own how-to guide on installing/configuring/maintaining the software, among others. What I haven’t been able to find thus far is a place where all of this information is altogether, in one place, for simplicity and ease of comparison to find the best solution for a network operator’s needs. This is where the RPKI Deployment Hub comes in. The RPKI Deployment Hub is the start of a documentation site that is designed to compile all of this information in one place. For new network operators this may prove to be an invaluable tool to find the best method of operating their own RP software, for students this may be a source of information to help further their studies, or for long-standing network operators it may be a resource for them to keep up-to-date with the latest methods. It is presently being hosted on GitHub pages, where each commit to the underlying repository updating the site live. The site itself is located at https://rpkihub.au<https://rpkihub.au/>, with the GitHub repository located at https://github.com/thesysadmindev/rpkihub. Unfortunately, I can only do so much, and this is where I need to ask for contributors to help work on this site. As we all know, there are a large number of router vendors on the market, each with their own way of implementing RPKI. Cisco, Juniper, MikroTik, Nokia, Arista, and the like all do things differently. It would be a wonderful world if they all worked the exact same way with the same commands. It’d make life a lot easier for us. What I’m calling out to the community for, is for assistance with building this site as it is impossible for me to look at every major hardware vendor and model. We need information such as router configurations relating to RPKI and the commands used, along with the vendor names, hardware models and software versions. The idea to this is that people can look at a guide, find their router model and it’ll tell them how to configure route object validation. As for creating ROAs, it’ll tell them how to do so with their respective RIRs. I understand that the best source of information for this is from the RIR itself and will always be the case; this is simply designed to provide everything in one central location. If there are any members from the other four RIRs (as I have already put together a guide for creating ROAs within MyAPNIC) who are willing to work with me to develop a guide with screenshots it would be greatly appreciated It could even be as simple as sending me an email with the steps listed and a few screenshot attachments and I can work on creating the guide otherwise you’re welcome to submit a pull request on the repository. I would also like to hear about people’s experiences with deploying RPKI across their networks, why you chose to and for those who haven’t or won’t, why that is the case. This sort of information would be valuable to help shape the site. If you would like to contribute to this project, you can do so via any number of ways: 1. Open a pull request against the repository on GitHub. 2. Click on the “Edit This Page” button on any page on the site to take you straight to its source on GitHub where you can make changes and open a PR directly from the GitHub site. 3. Send me an email to chris(a)thesysadmin.au<mailto:chris@thesysadmin.au>. 4. Drop me a direct message on Discord (Username: thesysadmin). The site itself is licensed under GPLv3, so feel free to tear it apart, share it and work together. If you also have any other recommendations as to how it can be improved or if you feel there is anything missing, do let me know. Regards, Christopher Hawker

Current diameter of the Internet?
by Sean Donelan 24 Jul '24

24 Jul '24

What is the current estimated diameter of the Internet? Maximum (worst-case) RTT edge-to-edge? Most public latency data is now edge-to-cloud, not edge-to-edge. Cloud engineers have done a great job, and edge-to-cloud less than 1-sec RTT. Where have the long-slow pipes gone? https://www.cloudping.co/grid https://learn.microsoft.com/en-us/azure/networking/azure-network-latency?ta… https://www.verizon.com/business/terms/latency/

While the sks-keyservers.net domain and many of the old hostnames that powered it are dead & gone, the actual SKS keyserver network does in fact live on, complete with new & improved DOS mitigations and active development of the underlying server software powering it, Hockeypuck. More information can be found @ https://spider.pgpkeys.eu/ & https://github.com/hockeypuck/hockeypuck respectively. Keyserver.ubuntu.com also exists, but has fallen out of sync with the network and to date has been unwilling to reengage. -T > On Jul 22, 2024, at 05:00, nanog-request(a)nanog.org wrote: > > Message: 15 > Date: Sun, 21 Jul 2024 20:23:43 -0400 > From: Matt Corallo <nanog(a)as397444.net <mailto:nanog@as397444.net>> > To: Randy Bush <randy(a)psg.com <mailto:randy@psg.com>>, North American Network Operators' > Group <nanog(a)nanog.org <mailto:nanog@nanog.org>> > Subject: Re: pgp keyservers > Message-ID: <23baf526-4319-49ba-aa6d-af3460ab925d(a)as397444.net <mailto:23baf526-4319-49ba-aa6d-af3460ab925d@as397444.net>> > Content-Type: text/plain; charset=UTF-8; format=flowed > > pgp.mit.edu <http://pgp.mit.edu/> has been sporadically available for me over the last while, but yea AFAIU sks-keyservers > shut down after the DoS drama, as did most of the old servers in the pool. > > I believe keyserver.ubuntu.com <http://keyserver.ubuntu.com/> generally works and doesn't strip all the signatures and whatnot off > keys when they upload. > > I think the hipster thing to do now, though, is --auto-locate-key with the Web Key Distribution or > the DNSSEC Key Distribution mechanism. > > Matt > > On 7/21/24 7:25 PM, Randy Bush wrote: >> are there any old keyservers still working? or only the new hipster >> ones? i tried three and no love >> >> hkps://pgp.mit.edu <hkps://pgp.mit.edu> >> hkps://pgp.uni-mainz.de <hkps://pgp.uni-mainz.de> >> hkps://hkps.pool.sks-keyservers <hkps://hkps.pool.sks-keyservers> >> >> randy >
