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.

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)

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

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.

Leftover budget? Consider a RIPE Atlas anchor
by Vesna Manojlovic 27 Nov '15

27 Nov '15

Dear all, The end of the year is coming closer, and you might be wondering, “What is the best way to spend some of the money still left in my budget, while at the same time contributing to the good of the Internet?” Why not consider hosting a RIPE Atlas anchor?! Investing in an anchor means you will: - Gain access to a wealth of measurement data (IPv4/IPv6 pings, trace routes) targeting your anchor from all the other anchors and hundreds of probes throughout the RIPE Atlas network, without spending credits - Earn 10 times more credits compared to hosing a regular probe that you can spend on your own customised measurements - HTTP measurements towards your anchor [1] - Have your logo included on the RIPE Atlas website [2] - Join a growing community that is providing great benefit to the Internet: there are currently 159 RIPE Atlas anchors around the world You can learn more about hosting an anchor here: https://atlas.ripe.net/get-involved/become-an-anchor-host/ Thanks, and happy holiday season!

[Request] System tags for DNS resolution
by Stephane Bortzmeyer 18 Nov '15

18 Nov '15

[Is there a better way to record enhancement requests for Atlas? Atlas has no public issue tracker, if I'm correct?] It would be cool to have system (automatic) tags for DNS resolution because some probes are using broken DNS resolvers. For instance, system-dns-works (modeled on IPv6's system tag) would be fine. Or may be system-dns-resolver-works (longer but more accurate). For instance, probes 16659, 17072, 17620, 17854 use a resolver which yields a REFUSED for any request and probe 19948, 20065 one with systematic SERVFAIL. [Is the maintainer of the probe automatically notified when there is such an issue?]

18 Nov '15

Dear RIPE Atlas users, Seven new RIPE Atlas anchors have been activated bringing the total number to 157. - Three anchors hosted by Leaseweb Network: us-mnz-as30633 in Manassas, Virginia, us-sfo-as7203 in San Francisco, California, and sg-sin-as59253 in Singapore. - jp-tyo-as13901, hosted by Afilias in Tokyo, Japan. - de-gaa-as56357, hosted by Technische Universität München in Garching, Germany. - cl-scl-as27678, hosted by NIC Chile in Santiago, Chile and sponsored by LACNIC. - pe-lim-as27843, hosted by Optical Technologies in Lima, Peru. The map of all anchor locations is available at: https://atlas.ripe.net/anchors/map/ You can access the anchoring measurements for all anchors at: https://atlas.ripe.net/anchors/list/ And here are the logos and links to hosting companies: https://atlas.ripe.net/get-involved/community/#!tab-anchor-sponsors We are still accepting new applications from organisations interested in hosting a RIPE Atlas anchor. We are particularly interested in deploying anchors in the Middle East, Western Asia, Latin America and Africa, in order to add more geographical diversity to the measurement data. There are more organisations that want to host a RIPE Atlas anchor but don’t have the necessary funding. To learn more about sponsoring an anchor, please contact us at mcb(a)ripe.net To apply for your own RIPE Atlas anchor: https://atlas.ripe.net/get-involved/become-an-anchor-host/ For any other questions, please contact us at atlas(a)ripe.net Regards, Michela Galante Measurements Community Building RIPE NCC

Any way to select the probes from upstream AS (not origin AS)?
by Stephane Bortzmeyer 16 Nov '15

16 Nov '15

Is there an easy way to select probes, not on the origin AS, but on an AS upstream? Example: probe 23865, IP prefix announced by AS 56339 which currently has only one provider, AS 16080. Currently, Atlas tells me there are no probes in AS 16080...

Feature request for Traceroute in RIPE Atlas
by Yue LI 13 Nov '15

13 Nov '15

Dear all, So far, the Atlas traceroute is such that if there are 5 consecutive hops with only timeouts (denoted by a star "*"), traceroute will directly try hop 255 and then stop the measurement, which means that the number of total hops can not be obtained. An example can be found: https://atlas.ripe.net/measurements/2841001/#!probes (the probe #22341) Unfortunately, the number of hops is so important to be used as a metric to evaluate the performance of a new protocol. Thus, I propose to add a configuration option for the number of hops after which traceroute decides to call it quits. I wonder whether there are somebody else are also interested in this new feature please?

edst 193.0.0.228 in traceroute results
by Yang Yu 13 Nov '15

13 Nov '15

Hello, In https://atlas.ripe.net/measurements/2928258, I did a UDP traceroute. "edst":"193.0.0.228" from first hop and second hop somehow showed up in the results after the last hop that responded to traceroute, which should have been a reply to buil-in measurement to tt01.ripe.net. And under maps tab the result is presented with the first 2 hops showing up after several non-responding hops. Is this a bug? I actually see it happening quite often in atlas traceroute results with firmware > 4680. Another example is https://atlas.ripe.net/measurements/2928262 >>> https://atlas.ripe.net/docs/bugs/ 2015-03-04 Before firmware 4680, traceroute could experience interference from other measurements. In general, periodic traceroutes did not interfere with other periodic traceroutes, but could experience interference from one-off traceroutes. Typically, this interference will show up in the 'edst' field. This problem was fixed in 4680. Thanks. Yang

Feature request for IP record route feature in RIPE Atlas
by Pavel Odintsov 11 Nov '15

11 Nov '15

Hello, dear Atlas Team! As host of RIPE Anchor #6111 I have some feedback about your awesome service! Thanks for your Great Job in measuring Internet! I would like to ask very important feature for measuring reverse trace route. I'm speaking about IP record route option which could track up to 9 hops of reverse path. I want to know path to my hosts from networks who haven't RIPE Atlas. Actually I could not implement this feature due to 9 hop restriction in IP header. But RIPE Atlas offer really huge coverage over the World and we could reach really any host with <7 hops. But we haven't this feature in RIPE Atlas. Finally with this feature we could build full adjacently map over all the World. I have checked implementation details here https://labs.ripe.net/Members/philip_homburg/ripe-atlas-measurements-source… Looks like we need to build separate libevent based toolkit for this task or add this feature to ping tool. But unfortunately I could not find any docs about deploy of RIPE source code for development. Could you share some information? -- Sincerely yours, Pavel Odintsov

RIPE Atlas anchor self assembly
by Michela Galante 10 Nov '15

10 Nov '15

Hi everyone, Some people on this list have been asking about the possibility of purchasing hardware for a RIPE Atlas anchor by themselves and assembling it. This is indeed possible. However we do not recommend it because if the assembled hardware is not exactly to our specifications, we will not be able to use it as an anchor. If you still wish to assemble an anchor by yourself, you can find step by step instructions here: https://atlas.ripe.net/docs/anchor-installation/ Please, note that you do need more than the Soekris box. The anchor consists of: • Soekris Net6501-70 board • 1U 19-inch rack-mounted case • Intel SSD 525 or 530 series 240GB mSATA SSD More requirements are listed here: https://atlas.ripe.net/get-involved/become-an-anchor-host/ If you have more questions about anchors, please email to atlas(a)ripe.net and we will be very happy to help you.
