HTTP measurements at willing targets / protocol suggestion
by Gil Bahat 27 Jan '16

27 Jan '16

Hi, We are interested (like many others, I guess) in the ability to perform HTTP measurements at our own non-anchored network. Understanding the potential for abuse, I would like to suggest the following authentication protocol, which is based on best practices exhibited by other services with such potential (abuse or privacy implications). 1. Confirm control of the domain registration: * This is usually done by mailing the technical contact for the relevant WHOIS entry with a confirmation email containing a unique hash, thus validating ownership. 2. Confirm control of the DNS servers: * This is usually done by editing the root TXT record with a unique hash or publishing a CNAME with unique hash. 3. Confirm control of the Web servers: * This is usually done by placing a uniquely-hashed file in the webserver root directory, a unique hash in the meta-tags for the index html file or a unique value in a file such as robots.txt. I believe this protocol is sufficient to ensure that a web site owner agrees to the implications of allowing free HTTP measurements against their servers and that no unwilling server will ever be probed. At most during the protocol, the only resource that can be hit is a static file or robots.txt specifically, which has very little capability to overwhelm a web server, especially if negative responses are cached for a considerable amount of time / validation is done via a few nodes and propagated across the network. thoughts/ideas welcome. Regards, Gil Bahat, DevOps Engineer, Magisto Ltd.

Dead probes
by Marty Strong 02 Dec '15

02 Dec '15

Hi, I've got 1 or 2 dead probes, they power on but I see no mac address from them. They have the first 2 lights on, but none of the others. I don't see this combination listed on https://atlas.ripe.net/about/faq/#what-do-the-lights-on-the-side-of-the-pro… Has anybody else come across this issue? Anybody know what the light combination means? Marty

Andrea, An important idea behind RIPE Atlas is that all results are re-useable. Therefore we store the results of *all* measurements as long as we possibly can because those results can be useful for other researchers even if they did not run the measurements themselves. Each result says something about the packet flow in the Internet at the particular time it was obtained. There is no way we can foresee how these results can help to answer interesting research questions and help us to understand the Internet packet layer better than we do now. For a recent example of this, please see https://labs.ripe.net/Members/becha/ripe-atlas-tools-hackathon-results "ASN Tryst". Therefore we do not provide the functionality of deleting measurements. The only way we foresee that results can be deleted is if we run out of storage space. Of course that one has to be careful to select the measurements one wants to re-use according to the question one wants to answer. Your measurement shows this very well. I do not recommend using your results unless the question is about reachability with RTTs under 6ms. I hope this answers your question Daniel (co-inventor of RIPE Atlas)

Measurements delete and ping issue
by Andrea Consadori 30 Nov '15

30 Nov '15

Hi all, i just start using proble atlas and i found is not possible to delete Stopped measurements from web, it's normal? i try to search on old mailing list messages and seems to be and old issue but i still cannot delete stopped masurements (for example ids: 3050379, 3034900) Another issue i see, if i create a ping measurement (id 3034899) under probes i see RTT column unreachable for every raw... but the public ip is pingable form everywhere.. maybe there's simple solutions i cannot found, if so can someone show me a good link where to found how to fix this two issues? Regards Andrea Consadori

Problem with Map Tab of DNS Measurement
by Klaus Darilion 30 Nov '15

30 Nov '15

Hi! I did a one-off DNS measurement: https://atlas.ripe.net/measurements/3050168/ As long as the measurement was running, I could click on the map tab. But now as the measurement is finished, the "map" tab is gone. While loading the site I see for a short time the tabs General information, Probes, Map and Results. But as soon as the site is loaded completely the Map and Probes tab are gone. Calling the map explicitely using https://atlas.ripe.net/measurements/3050168/#!map does also not work. Is this a feature or a bug? Thanks Klaus

New on RIPE Labs: RIPE Atlas Tools Hackathon Results
by Vesna Manojlovic 30 Nov '15

30 Nov '15

Dear colleagues, The second RIPE Atlas hackathon took place 13-14 November 2015 in conjunction with the RIPE 71 meeting. Impressive results were hacked together by programmers and operators during an intensive weekend of work and fun in Bucharest. In this article we celebrate the hackathon achievements and report about the benefits for the community in detail: https://labs.ripe.net/Members/becha/ripe-atlas-tools-hackathon-results Regards, Vesna ps to bring you some spirit of the event... http://www.memes.com/meme/784389

Feature Request Web Interface
by Klaus Darilion 30 Nov '15

30 Nov '15

When viewing the "Map" results of a DNS measurement some details will be shown in a pop-up when clicking on the respective probe. It would be great if the NSID (if available) would be shown too (not only Response Time and Serial) thanks Klaus

Spoofing measurenments
by Pavel Odintsov 27 Nov '15

27 Nov '15

Hello, Community! I'm writing from RIPE71 / Anti spoofing BoF. So I want to ask for some difficult ethical question. Could we detect probe hosts who do not deploy outgoing filtering and accept spoofed traffic? We need to know amount of they. It's really important for solving spoofing issue in Internet scale. -- Sincerely yours, Pavel Odintsov

[request]: probe timezone offsets
by Bajpai, Vaibhav 27 Nov '15

27 Nov '15

Hello, It would be nice to report a timezone offset for each probe via the probe API. Since measurements are reported in UTC, it's currently difficult to visualise a timeseries result in the local time of the probe. In order to do this, one has to turn the geolocations (currently reported in the probe API) of the probe to the corresponding timezone offset (which takes time) and then adjust the measurement timestamps by the timezone offset. It would be great if the timezone offsets of the probe are available via API. Thanks! PS: This is very low priority request.
