Invalid JSON because of DNS TXT records
by Stephane Bortzmeyer 15 May '15

15 May '15

The DNS, as we know, is a jungle. People put anything in their TXT records, even control characters. Atlas faithfully returns this content in the JSON files (see measurement #2004707). Then they are no longer legal JSON (RFC 7159, section 7) and crash the JSON libraries. Who should fix it? My first guess is that Atlas should not produce illegal JSON files and therefore should escape such texts.

Geographic Selection of Probe
by Graham Beneke 28 Apr '15

28 Apr '15

Hi All Due to the huge number of probes in Europe there is always a heavy bias when selecting "whole world" for UDMs. In the past I could get around this by requesting numbers of probes from each region/continent. I can't figure out how to do this on the new interface. Using the wizard there does not seem to be a way to request a random subset of probes within the area selected. When using the manual probe selection I can't find what area codes I can use besides "WW" Am I missing something? -- Graham Beneke graham(a)apolix.co.za

IPv6 auto-tagging failure?
by Bjørn Mork 21 Apr '15

21 Apr '15

Hello, I'm wondering a bit about the IPv6 auto-tagging. I recently reveived a v3 probe and connected it to a dual-stack enabled network. The probe was initially tagged as 2015-04-16 20:23 UTC Probe auto-tagged Your probe #22894 was automatically tagged as "system: IPv6 Capable" but then (on the next batch run?, after a couple of quick firmware upgrades (3.3.8 => 4650 => 4680): 2015-04-17 08:23 UTC Probe auto-untagged Your probe #22894 was automatically untagged as "system: IPv6 Capable" and there it has been since. This wouldn't worry me too much if it otherwise worked, but I noticed that the probe isn't listed with an "ASN v6" either. So I assume the missing tag prevents it from being used for v6 probing? AFAICS, the probe does take the announced prefix, and is actually *using* the provided IPv6 connectivity. The "Connection History" shows that it consistently uses its SLAAC address to connect to the controller. So why isn't it tagged as IPv6 capable/works etc? In desperation I tried different netwrok settings, static address, adding v6 DNS, and fiddling with the managed/other flags along with matching DHCPv6 config. Made no difference of course. If I understood correctly, the probe firmware won't currently do any DHCPv6, and v6 DNS is optional as long as there is a working v4 resolver available. Bjørn

RIPE Atlas accounting system renewal
by Robert Kisteleki 20 Apr '15

20 Apr '15

Dear Users, Today we're renewing our internal accounting system in RIPE Atlas. This change is almost exclusively internal, it hardly shows up on the public pages. If you see discrepancies regarding your credits tomorrow, then please let us know at atlas(a)ripe.net (ie. NOT this mailing list) so we can check. We'll privately contact the few users where we expect a more visible change. Regards, Robert & Johan & the rest of the team

Error when adding a measurement
by Edd Barrett 17 Apr '15

17 Apr '15

Hey, A friend offered me a v3 probe, and I am currently playing around with it, exploring what I can do. I think there may be a bug in the measurements setup process. When I try to add a measurement, I get a message: "AccBalance matching query does not exist." This is not a very user friendly message. Perhaps this is suggesting that I don't have enough credit? This leads me to another potential problem. On the landing page, after I login, there is a credit summary consisting of two icons and a kind of pie chart. If I mouseover "current balance" it says 0. If I click it, the resulting page says I have 50,000 credits (the welcome bonus). I suspect that I can't setup the measurement because some part of the system thinks I have no credit. Cheers -- Best Regards Edd Barrett http://www.theunixzoo.co.uk

Accounting switch
by Johan ter Beest 17 Apr '15

17 Apr '15

Dear Atlas users, We are in the middle of switching the accounting back-end. We expect this work to be finished by next week: Tuesday, April 21. There are two spots where you would be impacted: - Transferring credits Credits transferred will show up in the new system but not in the old. We have temporarily disabled the transferring of credits using the website. If you need to have some credits transferred urgently, you can email us at atlas-dev(a)ripe.net and we will make the transfer for you - When you register a new probe and are a first time probe host (ie, you have no credits at all) The 50.000 credits welcome bonus is applied to the new system while the measurements scheduling checks the old system resulting in an error. This is a fairly rare scenario as most of our hosts have credits already. When we spot this, we will contact the host and adjust his credits manually. There will be no danger of losing credits or measurements being stopped accidentally as a result of this switch. Thank you for your patience while we make this switch. Kind regards, Johan ter Beest RIPE Atlas Team

list of country codes / UDM via API limit
by Paul Vlaar 09 Apr '15

09 Apr '15

Hi all, is there a list of country codes that have active probes in them? I've used the ISO3166 list but am finding that many CCs do not have probes in them, so setting up those UDMs is moot. I am also running into what appears to be the limitation of the amount of UDMs that I'm allowed to setup using the API: around 25. Has anyone else run into that limit? Is there a way to raise that limit somehow? Thanks, ~paul

survey on performance measurement platforms and related standards
by Bajpai, Vaibhav 08 Apr '15

08 Apr '15

Dear RIPE Atlas WG, I would like to share something with you today. As you know, IETF LMAP [1] is making efforts to standardize large-scale measurements to allow divergent measurement platforms to converge towards interoperability. Early discussions within this group often lead to folks asking for feature sets and possibilities of each contemporary performance measurement platform. So we started digging literature work in this space and found that although there were surveys on topology-based measurement platforms (such CAIDA Ark et al.); literature work on performance measurement platforms (such as RIPE Atlas, SamKnows et al.) was missing. Therefore, we started writing such a survey in 2013 to plug this gap and also complement this with current state of IETF standardization efforts happening within the LMAP and IPPM working groups. This work got published and came online this week. I thought would share this with you: ----------------8<-----------------8<-----------------8<-----------------8< A Survey on Internet Performance Measurement Platforms and Related Standardization Efforts Vaibhav Bajpai, Jürgen Schönwälder IEEE Communications Surveys & Tutorials April, 2015 A number of Internet measurement platforms have emerged in the last few years. These platforms have deployed thousands of probes at strategic locations within access and backbone networks and behind residential gateways. In this paper we provide a taxonomy of these measurement platforms on the basis of their deployment use-case. We describe these platforms in detail by exploring their coverage, scale, lifetime, deployed metrics and measurement tools, architecture and overall research impact. We conclude the survey by describing current standardization efforts to make large-scale performance measurement platforms interoperable.

Finding out the number of simultaneous measurements
by Sebastian Castro 01 Apr '15

01 Apr '15

Hi: While running some measurements for a research work we are doing, I encountered this error "You can't have more than 100 simultaneous measurements". I'm not surprised, because I have some long term measurements running, but the bulk of them are one-off. Although I could throttle my measurements in little batches, I would prefer a way to programmatically query Atlas and find out how many measurements I'm running. The API allows you to get the list of public measurements, but running the query with an API key for my account doesn't change the output. Is there a way to do this with the API? Cheers, -- Sebastian Castro Technical Research Manager NZRS Ltd. desk: +64 4 495 2337 mobile: +64 21 400535

probes on VMs
by Klaus Darilion 30 Mar '15

30 Mar '15

Hi! I just found an old thread about virtual probes: https://www.ripe.net/ripe/mail/archives/ripe-atlas/2013-June/000849.html I second the problems of virtual hosts and that the results may not as good as other probes result, but there is a big advantage for virtual probes - I can host them in the cloud. For example, I just wanted to debug routing issues from the Microsoft Cloud in Brazil to our server. Unfortunately there are no probes in this Cloud's AS. With a virtual probe it would be quite easy. I order an VM with Microsoft, and have my probe in the chosen datacenter. The probe could be tagged with "VM" to show that it is running on shared resources. Of course the VM will produce extra costs, but there may be sponsors, and the smallest VM is usually enough. For example , one possibility would be, that the sponsor donates the money, e.g. 10-20€ per month, and chooses the cloud location. RIPE will then rent the VMs and run the probes. With several sponsors we could get a nice cloud coverage, and we could deploy probes in networks where the provider does not want to hosts physical probes. regards Klaus

We had the first RIPE Atlas hackathon! Three days of intensive coding, cooperating, learning, connecting and having fun (& surviving massive power outage on Friday in Amsterdam) - - and the results have bee impressive! Ten final projects have been presented, and four have been chosen as worthy of the awards: 1. Disco: Combining the visalization of disconnection-events with localized Twitter feed & live weather data 2. Spatial Bucketing of RIPE Atlas Probes on Map Projections (aka Picketty — making the global probe selection more equal) 3. Traceroute stability check & BGP+traceroute (two projects sharing the 3rd place) We had 24 participants & 1 no-show, 6 jury members and 11 support staff (coincidentally: 42!) On behalf of the community, we are grateful to Comcast for sponsoring prizes and travel expenses, hackerspace Technologia Incognita for the inspiring location on Friday, and to RIPE NCC for the office facilities during the weekend, staff support, food & drinks & amazing data & tools & platform of RIPE Atlas. On behalf of the organizers (RIPE NCC & Comcast), we are grateful to everyone who took part & contributed, as well as to their family & employers, who let them get away for the weekend of combined work&fun. Longer and more detailed report will follow, once we all get some sleep & collect our notes from tweets, IRC, mailing list & pieces of papers. Cheers, Vesna
