29 Jul '23

Hi folks, My name is Alexander Gamero-Garrido and I'm a 5th year PhD student at CAIDA, UC San Diego. We're soon launching a large traceroute campaign for research and could use your generous donation of credits. We'll need about 150 million credits, but any partial amount that gets us closer to that goal is welcome and greatly appreciated. My account is agamerog at eng.ucsd.edu Thank you, Alex -- *Alex Gamero-Garrido* *PhD Student, Computer Science* Web: cseweb.ucsd.edu/~agamerog Center for Applied Internet Data Analysis (CAIDA) San Diego Supercomputer Center UC San Diego Pronouns: He/Him/His <https://inboxwhenready.org/?utm_campaign=signature&utm_medium=email&utm_sou…> I'm using Inbox When Ready <https://inboxwhenready.org/?utm_campaign=signature&utm_medium=email&utm_sou…> to protect my focus.

Probe DHCPv6 support
by Aleksi Pirttimaa 19 May '23

19 May '23

Hi! I recently received my v4 probe and I'm very happy with it. But unfortunately it doesn't support DHCPv6. I present a practical reason for implementing a DHCPv6 client on the probe. You see, my ISP doesn't send router advertisements with the prefix for stateless autoconfiguration set, and instead DHCPv6 must be used. I believe their decision could have something to do with the fact that the regulating body here requires ISP's to prevent IP address spoofing in consumer plans. And to meet that requirement my ISP may be using a feature similar to Cisco's IP source guard, where switch ports and/or mac addresses are passively associated to leased ip's or prefixes, breaking SLAAC. Unfortunately they hate letting consumers talk with their engineers so it's difficult to speculate this further. For now, I've put a stateful firewall appliance in front of the probe which provides SLAAC, it works just fine. Do you think a DHCPv6 client should be implemented?

Error for getting measurement results from an api
by Sanaa GHANDI 30 Apr '21

30 Apr '21

Hello, I would like to use the Ripe api : /api/v2/measurements/{msm_id}/participation-requests/{source_id}/. for getting measurement results, but I keep getting the following error (in the picture). Here is the website of the different apis: https://atlas.ripe.net/docs/api/v2/reference/#!/measurements/Type_0_1_2_3_4… Is it due to my key? Knowing that I have already used it to create measurements and get measurement results and in other apis from Ripe. Concerning the example below, I have checked the measurement ID and that the probe in the source ID figures among the participant probes. I don't quiet see the source of the problem, do you have any ideas about this? Thank you, Cheers, Sanaa

Satellite based "last mile" and Atlas probes
by Eric Kuhnke 26 Apr '21

26 Apr '21

Hello all, I am running what I believe to be the only probe on a Starlink satellite connection right now: https://atlas.ripe.net/probes/1001821/ Is anyone aware of a list of probe ID numbers which are definitively known to be on some form of satellite-based access technology? I am thinking of, for instance, sites on consumer grade geostationary VSATs, more serious VSATs, or in island nations which are not known to have any submarine cables. The reason why I am searching for such a list is that I intend to consume some of my accumulated credits to run periodic one-off measurements of latency, traceroutes and other things to quantify improvements in satellite based latency and other performance metrics over time. And to quantify what it looks like when an ISP previously dependent on geostationary (min 495ms latency) gains access to either terrestrial/submarine fiber, or a lower latency low earth orbit based service. The best information I can find right now is to manually pick probes which never show below geostationary latency to a first hop in any traceroute, and are located on the probes map in certain island locations. It's a bit more time consuming to manually search for probes in continental locations which are on a VSAT (for instance if anyone knows of a probe on a VSAT terminal in a remote part of Wyoming, USA, let me know...).

RIPE Atlas CLI tools docker image
by Anurag Bhatia 26 Apr '21

26 Apr '21

Hello everyone, A little while ago I put RIPE Atlas CLI tools docker image based on alpine. - https://hub.docker.com/r/anuragbhatia/ripe-atlas-tools It stores the API keys at ~/.config on the host (and that is mounted inside the container). Dockerfile can be found here <https://github.com/anuragbhatia/ripe-atlas-tools/blob/master/Dockerfile> and one can use it to build image locally if intended to. *Example usage: * docker run --rm -v ~/.config:/root/.config -it anuragbhatia/ripe-atlas-tools ripe-atlas measure traceroute --from-country IN --target he.net One can set an alias in the local shell to make it appear almost like a locally installed setup. E.g on fish: anurag@Anurags-MacBook-Pro ~> alias ripe-atlas='docker run --rm -v ~/.config:/root/.config -it anuragbhatia/ripe-atlas-tools ripe-atlas' anurag@Anurags-MacBook-Pro ~> funcsave ripe-atlas anurag@Anurags-MacBook-Pro ~> Thus the reduces syntax is alias becomes: ripe-atlas measure traceroute --from-country IN --target he.net Please do share if anyone has any feedback. -- Anurag Bhatia anuragbhatia.com

Filtering measurements
by Sanaa GHANDI 23 Apr '21

23 Apr '21

Hello, I hope you are all doing well. I have a few questions concerning the measurements selection, and I am interested only on the anchoring mesh measurements. In fact, for optimisation issues, I would like to be able to select only measurements of interest: For example, I want to get the results coming from sources: X and Y, and targeting the anchor 6771. Now I can get the measures targeting the anchor 6771 using this code from Altas Cousteau ################################################################## from ripe.atlas.cousteau import MeasurementRequest filters = {'tags': ['anchoring','mesh',6771] } measurements = MeasurementRequest(**filters) #################################################################### But I have no idea of how to make a filter on the sources as well, since all we can access through the measurements are the number of anchors requested and not their ids. Do you know a way to get access to the sources of a measurement via Atlas Cousteau or another Ripe Tool ? Thank you -- Sanaa

Request for credits for research
by Mohan, Nitinder 20 Apr '21

20 Apr '21

Dear RIPE community, I hope you are all safe and sound. I am a Postdoctoral fellow at the Technical University of Munich, Germany. We are currently working on an ongoing research project which aims to analyze the availability and reachability of cloud data centers globally. The first work of our work will appear in ACM HotNets 2020 titled "Pruning Edge Research with Latency Shears" (http://conferences.sigcomm.org/hotnets/2020/program.html). We are currently preparing the camera-ready version of the paper and will share it with the community by hosting it (and the associated dataset) publicly soon. We are currently planing to submit the second leg of our work to a conference with submission deadline a month. In order to complete all set of measurements for required analysis, we are scheduling very large-scale measurements over the platform which has burned through almost all our credits and left us in need. I have always found the RIPE Atlas community to be helpful and generous towards research and I am hoping that you could support our research by donating us some of your spare credits. Your help will be highly appreciated. My RIPE account is nitinder.mohan(a)helsinki.fi Thanks and Regards Nitinder Mohan Postdoctoral Fellow Technical University of Munich, Germany <http://www.cs.helsinki.fi/u/nmohan/>https://www.nitindermohan.com/

Feature request for Validated Timestamps
by Will 15 Apr '21

15 Apr '21

I was starting to work on a mapping measurement project where I wanted to delegate measurements to remote machines. There are a number of schemes that have been used where a not fully trusted node can come away from a measurement with a record that can be used to verify that it actually made the measurement. Many of these make use of a time stamp signed by the "server" as a way to prevent replaying old measurements. Things that have been done with this feature also include tlsnotary[1], which works with web servers where the "server random" bytes of the tls handshake includes the server timestamp (the default for openssl). The implementation of ssl currently used by probes does not appear to include the timestamp in the server hello. Another approach would be to add a "roughtime" service on probes Interested to hear if there would be willingness to have probe software support something in this direction.
