Neues PeeringDB Objekt carrier // Visualisierung /// New PeeringDb object carrier // Visualization
by Arnold Nipper 02 Feb '23

02 Feb '23

[ English version below ] Hallo Gemeinde, mit Version 2.43.0 vom Mittwoch vergangener Woche hat PeeringDB [0] das neue Objekt "carrier" (Endpunkt /carrier) eingeführt, um damit auch L1- und L2-Dienste abbilden zu können. Das Objekt ist zunächst sehr einfach gehalten. Eine Organisation kann lediglich angeben, dass sie Carrierdienste anbietet und in welchen Colocationen/RZ (Endpunkt /carrierfac) sie vertreten sind. Dazu wird die Zustimmung des RZ-Betreibers benötigt [1]. Sollte das carrier-Objekt auf große Resonanz stoßen, wird PeeringDB das Objekt um spezifische Dienste (DF, Wellen, Ethernet, ...) erweitern. Um als Carrier gelistet zu werden, meldet ihr auch bei PeeringDB als admin an, geht über das Menue rechts oben zu der Organisation, für die ihr den Carrierdienst anlegen wollt und findet im 4. Tab die Maske. Ausfüllen, abschicken, fertig! // Jay Hanke (MICE/QCIX) stellt unter [2] eine KML-Datei zur Verfügung, die alle RZ in PeeringDB mit den IXP und Carriern auflistet. Tolle Sache! Jay schreibt dazu: --- You can create a "Network Link" from inside Google Earth [Pro] and refresh as needed. To create a network link, right click on "My Places" and select new Network Link. In the url use https://qcix.net/map/peeringdb.kml --- Viele Grüße Arnold [0] https://www.peeringdb.com/ [1] derzeit noch buggy, siehe https://github.com/peeringdb/peeringdb/issues/1315, wird umgehend gefixt [2] https://qcix.net/map/peeringdb.kml --------------------- English version Hello community, With version 2.43.0 from Wednesday last week, PeeringDB [0] introduced the new object "carrier" (endpoint /carrier) to be able to map L1 and L2 services with it. The object is initially kept very simple. An organization can only indicate that it offers carrier services and in which colocations/data centers (endpoint /carrierfac) they are represented. This requires the consent of the data center operator [1]. If the carrier object is well received, PeeringDB will add specific services (DF, waves, Ethernet, ...) to the object. To be listed as a carrier, log in to PeeringDB as admin, use the menu at the top right to go to the organization you want to create the carrier service and find the mask in the 4th tab. Fill out, send, and done! // Jay Hanke (MICE/QCIX) provides a KML file under [2] that lists all data centers in PeeringDB with the IXP and carriers. Great thing! Jay writes: --- You can create a "Network Link" from inside Google Earth [Pro] and refresh as needed. To create a network link, right click on "My Places" and select new Network Link.

Service Provider Network Topologies
by Urs Baumann 18 Jan '23

18 Jan '23

Good day, We want to analyse different network graphs from service providers in a Bachelor Thesis. Would anyone be willing to share the topology? Of course, the data can be anonymised. The students will need to find typical characteristics of service provider networks, and the thesis aims to create new topologies with these characteristics. Attached you can find the own-developed prototype helping to analyse the graph characteristics.

DNSSEC issue with swizzonic DNS servers?
by Benoit Panizzon 06 Jan '23

06 Jan '23

Hi List Fancy another DNS issue hunt? We have DNSSEC validation enabled on our BIND DNS Servers. We started seeing: no valid RRSIG resolving 'www.numberportability.ch/DS/IN': 2a01:8100:2901::1:183:202#53 no valid RRSIG resolving 'www.numberportability.ch/DS/IN': 2a01:8100:2901::1:183:201#53 no valid RRSIG resolving 'www.numberportability.ch/DS/IN': 81.88.58.219#53 no valid RRSIG resolving 'www.numberportability.ch/DS/IN': 195.110.124.196#53 broken trust chain resolving 'www.numberportability.ch/HTTPS/IN': 2a01:8100:2901::1:183:202#53 broken trust chain resolving 'www.numberportability.ch/AAAA/IN': 2a01:8100:2901::1:183:202#53 client @0x803541d60 X.X.X.X#27325 (www.numberportability.ch): query failed (broken trust chain) for www.numberportability.ch/IN/AAAA at query.c:7724 And of course the query fails, disrupting access some some quite important API. numberportability.ch. 900 IN SOA dns1.swizzonic.ch. hostmaster.swizzonic.ch. 2022121601 10800 3600 604800 86400 $ dig +dnssec RRSIG www.numberportability.ch @dns1.swizzonic.ch ; <<>> DiG 9.16.33-Debian <<>> +dnssec RRSIG www.numberportability.ch @dns1.swizzonic.ch ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 39132 ;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 ;; WARNING: recursion requested but not available So, from my point of view, the authoritative DNS server thinks, this is a recursive query and refuses to answer with the RRSIG, breaking validation of that record. Do you get to the same conclusion? Can you resolve this host via any other DNSSEC validating nameserver? I had no success contacting any technical inclined staff willing to look at the issue since the issue started on 16. December via hostmaster(a)swizzonic.ch by phone or via support(a)register.it. So if anyone from Swizzonic is reading here, it would be nice to get a direct contact to further investigate that issue.

DNS contact at Sunrise needed
by Filip Hruška 15 Dec '22

15 Dec '22

Hi there, We are seeing some DNS resolution issues for a specific domain through Sunrise's recursors specifically. Does anyone perhaps have a contact at Sunrise that could be helpful with debugging this please? Already tried normal contact methods listed in PeeringDB etc and have been ignored or told that they don't help non-customers. Regards, Filip

How to destroy data effectively?
by Martin Ebnoether 07 Dec '22

07 Dec '22

Hi all. As some of you know, I work at a money laund... financial company. Some time ago, the question arose, how to effectively destroy data safely and securely in an easy way? How does your company deal with hard disks (or any media) that needs to be decommissioned? Do you just dd a few times over it? Or rather let a professional company shred your media to little bits? CU, Venty -- 10 PRINT "BASIC programmers don't die." 20 PRINT "They just GOSUB without RETURN." 30 END READY.

Anyone else having email issues with Metanet?
by Benoît Panizzon 02 Dec '22

02 Dec '22

Hi List Yes, I am already in contact with Metanet techs. We have a very strange issue with two of their email servers. Connecting to Port 25 starts fine. SYN, SYN-ACK but then we start seeing re-transmits until the connections times out. This first happened to one of their server, then to another one, the the first server became reachable again at the beginning of this week, the second one still causes the same problem. The Problem also occurs the other way round. Metanet is unable to establish tcp connection to port 25 on rrmx.imp.ch Is anyone else seeing such an issue, either to metanet or towards our rrmx.imp.ch? Has anyone any clue what could cause such an issue? I compared traces of tcp connections to both of the affected metanet servers, to the working one and to the one causing re-transmits. The two initial SYN and SYN-ACK look identical and then to one destination the re-transmits start and to the other destination I get the SMTP HELO banner. PS: Yes, I did disable the firewall on our mail-plattform and re-test. This does not seem to be the cause. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Sudden RTT drops after changing fiber OTO plug
by Mat Kowalski 29 Nov '22

29 Nov '22

Hi folks, This is mostly to satisfy my curiosity, but if someone has technical insights I would be more than happy to hear. Background - yesterday my residential Sunrise fiber has changed the OTO plug from #1 to #2 (in Zurich). It's still XGS-PON, it's just that I'm using a different line now. I have a setup that runs a continuous ICMP test towards various targets. I have observed that after changing the fiber plug, all the RTTs suddenly dropped. My guess (may be wrong though) is that with OTO#1 I was connected to a more complex PoP setup than with OTO#2 and this is what reduced the RTT. For interested, here are 3 graphs presenting the drop. For every graph the left side is OTO#1 and the right is OTO#2. Monday morning was the time of changing the line: 1) https://i.ibb.co/qRL1Hyb/1.png 2) https://i.ibb.co/9ZL60KB/2.png 3) https://i.ibb.co/k2YJzJL/3.png Cheers, Mat
