Empty from feild
by john 06 Jun '14

06 Jun '14

Hello All, Quick question about the data format. What would cause a measurement to have an empty from field but contain data? An example would be probe_id 13663 from measurement 1672218[1]. A cursory glance seems to happens a lot more with V6 Thanks John [1]https://atlas.ripe.net/api/v1/measurement-latest/1672218/

Probe not showing IPv6 ASN and subnet on map
by JC 02 Jun '14

02 Jun '14

Hi, We just setup our probe (id: 17328) and configured static IPv6 on it. Built-in measurements to IPv6 destinations seems to perform correctly from this probe. However, when we display detailed information about the probe on the coverage map https://atlas.ripe.net/results/maps/network-coverage/ we only see IPv4 information and no IPv6 subnet or ASN. Besides, searching for our IPv6 ASN (21538) in the filter field brings no results. Thanks for your help. Regards, JC

Hello, Just received my probe today, Registered it, plugged it, all leds seem correct. I've followed the instruction on page https://atlas.ripe.net/get-involved/become-a-host/ where one can read: "Once we see that your probe is connected to the RIPE Atlas infrastructure, you'll be able to see it listed on the Public Probes page and, when you are logged in to the RIPE Atlas website, it will appear under the "My Probes" tab on that page. But, although logged on the web site I'm unable to find this "My Probes" tab on the "Public Probes" page Could someone help? -- Gilles

Measurement creation tools and library
by Matt Calder 28 May '14

28 May '14

Hi, I'm announcing a set of Python-based command-line tools/library for measurement creation available at https://github.com/USC-NSL/ripe-atlas. Since the focus is heavily on assisting measurement creation, I think that it should compliment Sagan nicely. It has been slowly under development for a while now but still has plenty of room to grow in supporting all of the options for different measurement types. Thanks, Matt

Feature you asked for: "latest results" API
by Vesna Manojlovic 27 May '14

27 May '14

Dear RIPE Atlas community, last week we enabled a new feature that quite a few people had an interest in: an API that lets you get up to 10 most recent results of any measurement: https://atlas.ripe.net/docs/measurement-latest-api/ We wrote an article with more details: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-latest-resul… From the article: "This new feature could come in useful in a number of different situations, such as: - Creating a widget for a website that monitors a specific result in near real time, such as ping results from 100 probes around the world toward your own website - Monitoring your network by setting up an alert based on the average measurement result from the past hour - Staying aware of a major network event, such as an Internet outage in a certain region - DNS monitoring of your own domain, with configurable measurements using 10 RIPE Atlas anchors - Prototyping a script using RIPE Atlas data" Please let us know if you find other creative uses for this new API! If you develop custom code for configuring the results of this API, please share it at the GitHub RIPE Atlas Community repository: https://github.com/RIPE-Atlas-Community/ripe-atlas-community-contrib We would love to hear your success stories! Regards, Vesna

Unable to connect my probe
by Vincent Roussillat 27 May '14

27 May '14

Hello I've received my probe #16969 yesterday, registered it and tried to connect it behind my Orange Livebox here in France. It doesn't succeed to get connected and even doesn't get an IP from the DHCP server of my box (which delivers IP address to my other devices). I have tried this morning to connect it to another Internet access, at work and this failed too. Led #4 remains blinking. I can see in MyAtlas interface that the probe got connected just after the first boot, as I can see to request to DNS servers logged in the interface. May be, an upgrade began and got interrupted, leaving the probe in a strange state, I don't know... Anyway, what should I do now ? Request another probe ? Send this one back to the RIPE ? If so, where should I send it ? Regards.

Introducing: the new result parsing library (Sagan)
by dquinn 26 May '14

26 May '14

Hi everyone, in advance of the RIPE Meeting, I thought I'd let you all know about the new parsing library we've developed for use against measurement results. This was mentioned in a recent RIPE Labs article[1] but I thought it worth detailing here for those of you who aren't avid Labs followers. The idea is that you run every result you get through this handy Python library and out comes programmer-friendly Python objects. It supports the various changes in result format over time, and even does some of the heavy lifting for you like calculating ping median rtt, parsing the DNS abuf, or counting the traceroute hops. The project code is published on GitHub[2], and pull requests are welcome. Installation can be done via Pypi[3], and documentation is included in the module and available online[4] as well If you have any questions feel free to post to the list and one of us will see what we can do for you.

Probe cannot connect from behind IDS/IPS with HTTPS inspection
by Ondřej Caletka 21 May '14

21 May '14

Hello list, I just observed strange behaviour of one Atlas probe. It was unable to connect to the control server from a corporate network. I suspect that some IDS/IPS appliance detects and drops probe attempt to use port 443 for non-TLS traffic*. I've tested it by trying to SSH to control server from within that network and it failed. However, normal SSH to port 22 works fine. It would be nice if the probe would be able to try more ways to reach the control server, eg. first attempt on port 443, second on port 22, third on some arbitrary high port number. I know that it would be better to put the probe in front of the firewall/IPS, but this is much more complicated in many corporate networks. *) At least it doesn't do MitM on HTTPs traffic. I've checked that too. Cheers, Ondřej Caletka

Some UDM comments
by Jared Mauch 19 May '14

19 May '14

I'm working on creating some measurements and haven't quite moved into using the API yet and wanted to provide some feedback: 1) When creating a UDM, when it's scheduled but not yet assigned to probe(s), it would be nice to be able to increase the # of probes. 2) When creating a UDM and specifying source ASN, you can't type in that box and must use the pull-down. Related to #1, if you increase probes to (eg: 5) it resets to 1 after you select the ASN. 3) When stopping a UDM that is set for ongoing/no-end, it would be nice to have a 'stop now' vs having to pick the next 15 minute interval. In theory the system could auto-populate this. 4) I do like the probes/map/seismograph view, is it possible to provide a direct-link to these public UDMs without logging-in? (I haven't looked closely so there may be a way to do this). Trying to not need to fetch the data and generate my own graphs... 5) If I see a probe that is behaving poorly, eg: UDM 1665566 Probe# 3925, should I be providing feedback on this to others? I'm working on a Nx(N-1) measurement of these ASNs to determine which have persistent congestion that can be measured via RIPE Atlas if that is of interest to others. 174 209 701 1239 1299 2828 2914 3320 3257 3356 3491 3561 5511 6453 6461 7018 Those interested in this, I will be able to send you a list of UDMs to look at which are public. - Jared

Taking the fuzz our of client cache results
by Mark Delany 17 May '14

17 May '14

Hi. I've been running some DNS queries using the probe caches with a view to understanding the latency between the probe cache and the authoritative that I'm interested in. The problem is that there is a fair degree of uncertainty in these measurements because the cache may have to first resolve higher level names in the hierarchy and there is no way of knowing whether the cache had to do this or not. If my query is for www.example.com, it's quite possible that the cache has to first resolve example.com prior to sending the final query for www. This means the measurement may include the cost of getting an answer from .com *and* getting the answer from example.com... sometimes. Depending on how popular example.com is and what other clients are doing with the cache. I'm wondering if there is a way in which we can eliminate this fuzziness? The most obvious way to do this is to ensure the cache is pre-primed with every answer up to, but not including the target name. If we assume the measurement request includes a new "prime cache" flag, then in the presence of that flag the probe could first run a query for something like: cacheprime.example.com substituting the first label with some other value. Alternatively it could first run an NS query for example.com A third alternative is that the creator of the measurement could nominate the priming query as they will have the knowledge needed to get it right. A forth alternative is that the probe could run the query twice - with a nominated delay that is known to exceed the TTL of the target query. In all cases, as soon as the priming query is complete, the probe then runs the target query with a high degree of confidence that the cache only needs to make one round trip to the authoritative server. There is still a small probability that the results will be fuzzy for a variety of reasons, multiple cache choices, anycast caches, super-busy caches, multiple probes using the same cache, but that probability will be very low. Also, a pre-primed query would presumably cost twice as many credits since it's really running two queries. Do others think a primed cache query is of use? And, are there ways of achieving this already? Mark.

network coverage and probe API
by Bajpai, Vaibhav 23 Apr '14

23 Apr '14

Hello, The network coverage page [1] shows around 10K+ registered probes. However, if I call the probe API [2], the total_count field shows 8K probes. Probe objects also have is_public field, so I assume the API counts both public and private probes. There is also a status field, so I assume the API counts connected, disconnected and abandoned probes as well. What am I missing?

Hello, Traceroute UDMs include an interval parameter. If I provision a one-off traceroute UDM via the GUI wizard, the interval field should get disabled no? Once the measurement is completed, the general information tab for the UDM now shows the interval for a one-off measurement as 900s. PS: We understand the interval parameter may have made no difference to the actual measurement. This is more of a bug report for visual side of things.

Related to Rip Atlas Credit System
by Roya Ensafi 14 Apr '14

14 Apr '14

Hi all, Considering RIPE Atlas credit system, ping and tracerout unit cost calculations are tricky. It closely depends on number of packets in train and size of the packets. Based on [1], predicted cost of a traceroute measurement with sent packet size of 2040 and 3 as number of packets (detail arguments are bellow) should be 10*3*(int(2040/1500)+1) = 90 (refer to [1]). However, predicted cost calculated by RIPE server is 120. After looking at available JavaScript, we couldn't find the predicted cost calculation. It sounds like calculation happens on server side and then the the value is returned. Is it possible to check the server code i.e. is the cost function calculation on server side publicly available? Thanks, Roya Enasfi [1]: https://atlas.ripe.net/docs/credits Details for a traceroute measurement : (Per result: 120.0 credits, Estimated total cost: 120 credits) Arguments: (Interval: 900 seconds, Resolve on probe: No, First hop: 1, #packets: 3, Don't fragment: True, Max hops: 32, Tcp: True,Paris: 16, Timeout resp.(ms): 4000, Port: 80, Size: 2040)

14 Apr '14

Dear RIPE Atlas users, We're happy to announce that another RIPE Atlas anchor has joined the network and is now available as a target for probe hosts conducting their own user-defined measurements. The new anchor is called au-bne-as4608 and it is hosted by APNIC in Brisbane, Australia. This is the second anchor hosted by an RIR on behalf of the RIPE NCC. Anchoring measurements (ping, ping6, traceroute and traceroute6) are scheduled towards this anchor from all the other anchors as well as several hundred probes, providing a continual overview of regional reachability. Results of these measurements are available as raw data in JSON format, and visualised on the map and "seismograph" with many configurable features. You can access the anchoring measurements for all anchors at: https://atlas.ripe.net/anchors/list/ Learn more about RIPE Atlas anchors at: https://atlas.ripe.net/about/anchors/ Thank you for participating in RIPE Atlas!

"Invalid group id" for Restful API?
by Philipp Winter 11 Apr '14

11 Apr '14

I'm trying to create a measurement using Atlas' Restful API [1]. Before that, I created an API key for measurement creation. Using my API key, when executing the simple example shown in [1], the server tells me: > {"error": {"code": 104, "message": "group: Invalid group id"}} I get the same error code with different JSON-formatted queries. Any ideas what's going on here? [1] https://atlas.ripe.net/docs/measurement-creation-api/ Cheers, Philipp

Using ripe data results on publications?
by Daniel Gomez 08 Apr '14

08 Apr '14

Good Morning everyone, What is the policy about using ripe atlas results on articles and publications? We know atlas is a great infrastructure to perform measurements, but we can find on them , i.e. traceroute, private IPs from atlas hosts networks. I know there is a lot of people on this list concerned about making public some information. Are atlas results open to share and so the probes information? Greetings, Daniel Gomez

Probe IPs are public?
by Roman Mamedov 08 Apr '14

08 Apr '14

Hello, I was under impression RIPE tries to somewhat anonymize probe information that's displayed publicly, e.g. only showing the probe IP address information down to the subnet or AS level on the maps, providing the option to use "Obfuscated DNS entry", etc. But on the public stats pages e.g. here: https://stat.ripe.net/widget/atlas-probes#w.resource=DE (+ "switch to table view") I am able to see both IPv4 and IPv6 addresses of many or most probes without even having to log-in; is that intended? Also what is the point of choosing to use the Obfuscated DNS option if the probe IPs are available in the clear anyway. -- With respect, Roman

Net Neutrality measurements
by Georg Chytil 31 Mar '14

31 Mar '14

Dear collegues, I sympathize with the cause for net measurements, and the RIPE Atlas project in particular. I´d like to draw your attention to the use of net measurement infrastructure as a means of documenting net neutrality, and a consulation of BEREC in this context: http://berec.europa.eu/eng/news_consultations/ongoing_public_consultations/… I´d appreciate if RIPE got involved in this field before less desireable and competent parties do ;-) Maybe comment on net neutrality on https://atlas.ripe.net/about/future-plans/ ? Kind Regards #g

Use case for RIPE Atlas: DNS service disruption in Turkey
by Vesna Manojlovic 31 Mar '14

31 Mar '14

Dear all, one of our most active users, Stephane Bortzmeyer, performed RIPE Atlas (and other) measurements to collect the data for his analysis, published in a blog post yesterday: "Hijacking of public DNS servers in Turkey, through routing" http://www.bortzmeyer.org/dns-routing-hijack-turkey.html Thank you for this interesting use-case! This is a call for the rest of the community to let us know if you have done some measurements or analysis to solve your problem, or to better understand a network-event - please share it with us. We are also interested in re-publishing your stories on RIPE Labs. You can find the previous articles here: https://labs.ripe.net/atlas Regards, Vesna

Hi folks, I had a look at the list of my ambassador probes and noticed that one of them is currently listed as being off-line (ID 12734) The probe ID is rendered as a link, with this URL: https://atlas.ripe.net/ambassadors/probes/%7B%%20url%20'probe-detail'%20pk=record.prb_id%20%7D%7D which comes back with " Bad Request Your browser sent a request that this server could not understand.

8.8.8.8 hijack and ripe atlas
by Jared Mauch 20 Mar '14

20 Mar '14

It appears there are some public measurements like #1002630, and i'm curious if someone is able to look at the latency and TTL numbers of the transport side and observe the localized hijacking of 8.8.8.8. The dataset is somewhat huge and i'm not a json master so trying to discern if there is evidence in there is something i'm looking at. - Jared

life-cycle of a probe?
by Wilfried Woeber 19 Mar '14

19 Mar '14

Hi folks, is there a way to find out when a particular probe (under my control[1]) was seen by a/the collector(s) for the first time? The best I have come up with is to look at the raw data download, but I'm not sure that the data has been preserved for raw download in the "early days". Thanks, Wilfried [1] just in case, I am interested in ID 466 and 414
