Local network checks
by Alison Wheeler 11 Apr '16

11 Apr '16

Recently my probe stopped responding to RIPE even though it was pingable through the local network. Putting aside what the cause might have been* is there any way to 're-awaken' or cycle in some way a probe without physical access to it? (* sfaict it didn't restart when the USB socket on the server it takes power from was remotely restarted) Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Failing 4GB USB on v3 probes?
by Phillip Remaker 11 Apr '16

11 Apr '16

So far, I have had two of the SanDisk Cruzer 4GB drives (SDCZ33) fail, and I think I have two other ML-3020 (v3) devices with the same fate. Case #1, the drive fell into read only one. Case #2, the drive identifies to the USB, but read of block 0 (capacity) fails. The first time I called SanDisk and jumped through their hundred hoops to replace it.They were reluctant since I couldn't produce a receipt. This time, I just grabbed an old 8GB USB and dropped it in. Looks like it only uses 3GB. Does Atlas plan to pursue warranty claim, or is this an acceptable failure level for the probes?

Flow-id of built-in traceroute measurement
by Wenqin SHAO 08 Apr '16

08 Apr '16

Dear list, I have some questions concerning the flow-id of built-in traceroute measurements and are seeking for your help. As many of you may have already noticed, the flow-id of the built-in traceroute measurement periodically varies form 0 to 15, in a circular manner. With this behaviour, it is supposed to reveal the diversity of underlying IP paths. In the case that there are more than 16 unique IP paths between a source and destination pair, could this scheme reveal all of these IP paths? If it can, which leads to more than one IP paths per flow-id? Is it normal, from a load balancer point of view? If it can not, then why not a wider range of flow-id (more nuances in header hash results), say [0, 63]? Is it related to common realisation of load balancer? Many thanks in advance. Best regards, Wenqin ==== Wenqin SHAO PhD Candidate Telecom ParisTech

Scheduling a test for all probes?
by Jared Mauch 06 Apr '16

Is there a way to schedule a one-off test on all the probes to be run “at a leisurely pace”, eg: looking up a specific DNS QNAME? (I’ll call it a lazy query/scheduling). - Jared

Research using RIPE Atlas probes: How Pingable are the Pingables?
by Vesna Manojlovic 05 Apr '16

05 Apr '16

Dear colleagues, take a look at how the "pingable:" and "ping-hdl:" attributes have been adopted in the last five years and how reachable the pingable addresses registered in the RIPE Database are when pinged from RIPE Atlas. Spoiler alert: It could be better. Please find the details on RIPE Labs: https://labs.ripe.net/Members/wilhelm/how-pingable-are-the-pingables Kind regards, Vesna

Credits sharing and other new features
by Vesna Manojlovic 04 Apr '16

04 Apr '16

Dear colleagues, many of you have been asking for the credits sharing options, and now we have added two new ways that you can go about it: - standing orders - share access - and the transfers are still possible too All about credits: https://atlas.ripe.net/docs/credits/ In addition to that, in the past few months, we've added some other new features and functionality to RIPE Atlas, including making the DNSMON code available on GitHub for personal use, displaying IPv4 vs IPv6 comparisons in LatencyMON, and new limits on probes per measurement and results per day. Learn more about the latest updates on RIPE Labs: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-altas-update-dnsmo… Regards, Vesna

Re: [atlas] [ripe.net #1204062] request to add three more ccTLDs to, DNSMON: CR, SG, and TW
by Romeo Zwart 04 Apr '16

04 Apr '16

Hi Peter, You have recently requested to have three ccTLD zones be added to DNSMON. Unfortunately, since the zones do not fall into the RIPE service region and the zone owners are not members of the RIPE NCC, the request does not qualify according to ripe-661. If the zone owners do wish their zones to be monitored by DNSMON we need to ask them to become members of the RIPE NCC. Alternatively they could argument an exception for their case with the DNS working group. Apologies for the confusion. Feel free to contact us if you have further questions.

probe tagged as "system: Firewall problem suspected"
by sarah.wassermann＠student.ulg.ac.be 02 Apr '16

02 Apr '16

Hi, I have (once again) problems with my probe (probeID: 24102). This time, it got tagged as "system: Firewall problem suspected". The strange thing is that I did not touch anything on my router when this happened and did not change any other configuration... This probe is located in Luxembourg. I now brought it to Belgium and plugged it into the router I have here. Nothing changed. Furthermore, here in Belgium, its 3rd light is slowly blinking, which let's suppose that it gets tuck in the network-testing phase. Anybody knows how to fix this? (I already had some problems with that probe ("system: Hardware problem suspected") but I could solve them thanks to a hint given by a user.) My worst problem is that, due to this issue, we have difficulties earning enough credits for our research... So I would be really happy if this problem could be solved easily :( Thanks! Sarah

Implementing structured error reports ("Problem Details for HTTP APIs")?
by Stephane Bortzmeyer 01 Apr '16

01 Apr '16

Hello, IETF approved the future RFC draft-ietf-appsawg-http-problem "Problem Details for HTTP APIs" which standardize structured error reports (in JSON) to add machine-readable information to HTTP error codes. Would it be a good idea to convert current Atlas reports ({"error":{"status":400,"code":104,"detail":"__all__: Your selected prefix is not covered by our network.","title":"Bad Request"}}) to the new and standard format?

IPv6 working
by gboonie 30 Mar '16

30 Mar '16

Hi, This seems to be an anchor that has Ipv6 connectivity but probably connected to a network with a incomplete routing table. https://atlas.ripe.net/probes/6149/#!tab-builtins It cannot reach a lot of the internet so I'm wondering what causes the system to flag it as "ipv6 works". Also, I've done a few hundred pings and found that probes get their "ipv6 works" only taken away after it has been failing for a few hours. Could that please be changed to something short like 10 minutes? And if possible, some stability tests so that if connectivity comes and goes that if does not get back it's "works" status. Thanks, Dave

Re: [atlas] Probe not flagged as "IPv4 works"
by gboonie 24 Mar '16

24 Mar '16

Hi Philip, A powercycle did not help. I did a reboot without USB stick and formated it in my laptop. Then plugged it back and after some minutes it started working again. Some googeling showed that the stick can be replaced by a 4GB stick but the one that it currently has seemed to be only 1GB. What is your view on this? The other strange thing is that the probe did somehow earn credits. That seems to contradict that it was down. On the other hand the "Connection and traffic" graph clearly shows that it is up after been down.

Probe not flagged as "IPv4 works"
by gboonie 23 Mar '16

23 Mar '16

Hi, I have 3 probes in different networks. This one probe is not selected for tests when I do a test on multiple probes that I select op probe ID or ASN. This is the troubling probe: https://atlas.ripe.net/probes/24645/ It is connected via a 4G LTE router. The router is up and everything else works. I could just reboot the modem and the probe but I'm wondering why it fails to get flagged with "IPv4 works". The "built in" test seem to work fine. What could be the issue? Is there something I could do to debug? Or just reboot and forget about it? Thanks, Dave

Fwd: New on RIPE Labs: Support for Elliptic Curve Cryptography (ECC) in DNS Resolvers as Seen by RIPE Atlas
by Vesna Manojlovic 21 Mar '16

21 Mar '16

Dear colleagues, Please find this new article on RIPE Labs contributed by Maciej Andzinski: The Elliptic Curve Cryptography (ECC) is becoming increasingly popular in DNSSEC. While it is sometimes considered to be a remedy for the low DNSSEC adoption rate, there is also a lot of controversy around it. One of the main concerns is that DNSSEC-validating resolvers don't always make use of ECC. We used RIPE Atlas to measure the support for ECC in DNS resolvers. https://labs.ripe.net/Members/maciej_andzinski_2/support-for-elliptic-curve… Kind regards, Vesna Manojlovic RIPE NCC

DNS64 system tag using RFC7050
by Pier Carlo Chiodi 09 Mar '16

09 Mar '16

Hello, I would like to recall this short conversation that appeared in ipv6-wg: https://www.ripe.net/ripe/mail/archives/ipv6-wg/2015-November/002747.html I was wondering if it is worth adding a new system tag to probes: something like system-dns64. >From a quick analysis that I made using RFC7050 [1] I noticed that only a handful of probes are behind a DNS64 box, but I think it would be useful to have them tagged, to avoid spending credits to detect them every time. Or perhaps the game is not worth the candle... In that case, you can find my results as of yesterday there on GitHub.

Querying your own measurements
by Sebastian Castro 09 Mar '16

09 Mar '16

Hi: I'm currently testing the API to get a list of my own measurements. The API here reports ----------- Querying for Your Own Measurements In order to limit the results to your measurements only, just add a mine=true argument. For example: /api/v1/measurement/?mine=true Note that this only works if you're logged in, otherwise the result is the same as for any unauthenticated user. ----------- This seems to imply you need to manage a session within your code to get your own measurements, which I think violates the principle of a REST API. If you have the API key that provides you with access, shouldn't be reasonable to run the call as /api/v1/measurement/?mine=true&key=API_KEY and get a list of your own measurements? Thoughts? Am I reading the documentation in the wrong way? Thanks in advance -- Sebastian Castro Technical Research Manager NZRS Ltd. desk: +64 4 495 2337 mobile: +64 21 400535

Detecting additional information from the probes
by Christoph Rauterberg 15 Feb '16

15 Feb '16

Ahoi everyone, I am currently trying to asses the behaviour of DNS queries between clients and authentication servers - and I would love to trace some DNS pakets between the probes and my server. I was wondering, if there is some way to get the information about the Authentication Bit of DNSSEC specified in the DNS query headers. A.f.a.i.k., the probes do something similiar/do a /dig/ lookup. /dig/ does provide information about the DNSSEC-section - and furthermore it has a very handy /+trace/ option. Can anyone maybe tell me, if there are possibilities to access the AUTH bith or even something like a trace function via the probes? Or should I open a feature request for that? Help much appreciated! :-) Best regards, Chris

Triggering traces from probes in specific cities
by Anurag Bhatia 10 Feb '16

10 Feb '16

Hello everyone, I was looking at possible command line tool to trigger traces from Atlas from given city or that area. The closest I can see is RIPE Atlas Tools - https://github.com/RIPE-NCC/ripe-atlas-tools but these let to only put source country or region. 1. Is anyone aware of how one can trigger traces via CLI from specific cities? *(I would love to do trace from a nearby city if specific city does not have Atlas coverage)* 2. In the Ripe Atlas Tools I see in documentation it refers to an argument "[--paris paris]". Is anyone aware of what does it mean? It seems to be asking for an integer value.
