Results of the DNS Measurements hackathon - article now published on RIPE Labs
by Vesna Manojlovic 11 May '17

11 May '17

Dear all, in April we held a fifth hackathon. Altho the topic was DNS, most of the projects were using RIPE Atlas data. Therefore, I invite you to check out the hackathon results, follow the links to the code, and enjoy the photos that attempt to transfer some of the atmosphere.. https://labs.ripe.net/Members/becha/results-dns-measurements-hackathon Please do take part: - use the tools/SW and let us know your experiences with it - modify the code & publish it again on GitHub - join our next hackathon - as a host, sponsor, or participant (date & location & topic to be announced soon!) Let me know in person if you are interested; and otherwise, post your comments or questions on the list, greetings from RIPE74, Vesna

Many timeout-failures for DNS over TCP
by Davey Song(宋林健) 11 May '17

11 May '17

Hi folks, I setup measurements for DNS queries over both TCP and UDP. I found the timeout and failures of TCP is far more than UDP. For example : DNS over TCP: https://atlas.ripe.net/measurements/8552847/#!probes DNS over UDP: https://atlas.ripe.net/measurements/8552846/#!probes Is it normal ? I mean is there any special timeout routine/parameters of atlas probes from normal resolver? Best regards, Davey

Are there plans for faster than 1G anchors?
by Bryan Socha 20 Apr '17

20 Apr '17

We're finding it harder and harder to support the 1G nic interface on the anchors. We'd love to add more but would need a 10g port at minimum (25G or 40G would also work). Are there any plans to update them for networks that can't easily support a 1G nic? Bryan Socha Network Engineer DigitalOcean

status-check misbehaving
by Georg Kahest 19 Apr '17

19 Apr '17

Hello, Am I misunderstanding something or the status-checks are kind of broken: Yesterday i made new measurement: https://atlas.ripe.net/measurements/8038852/ I noticed some probes werent reaching my ipv6 host, so decided to remove them like you can see from the Probe specifications section. Now when i goto https://atlas.ripe.net/api/v2/measurements/8038852/status-check/ I can still see the removed probes in status-check page (which contains 17 errors ) in reality if i'm lookin at measurement probe page i should have only two errors. So it seems that status-check isnt updated once probes are removed from a measurement. -- Georg Kahest System Administrator / Süsteemiadministraator Eesti Interneti SA Paldiski mnt 80, 10617 Tallinn Tel 727 1016 www.internet.ee

Behind the scenes changes to measurement creation
by Chris Amin 18 Apr '17

18 Apr '17

Dear colleagues, Today we deployed behind-the-scenes changes to the measurement creation process, both when using the website and the REST API. These changes should not have any visible effects, with the exception of improvements to the measurement API reference[1] to make it easier to see which options belong to which measurement type. Although we've tested these changes extensively, they are significant so I am sending this mail to ask you to please let us know if you notice any problems or changes when creating measurements. Kind regards, Chris Amin RIPE NCC [1] https://atlas.ripe.net/docs/api/v2/reference/#!/api/Measurement_List_GET

Dear colleagues, TraceMON is a client-side tool for visualising network topology generated by traceroutes reaching one or more targets in a network. It provides a one-click access to a set of information useful during day to day operations. Please find more details on RIPE Labs: https://labs.ripe.net/Members/massimo_candela/tracemon-traceroute-visualisa… Kind regards, Mirjam Kuhne RIPE NCC

Problems trying to add a probe to a measurement
by Colin Strutt 07 Apr '17

07 Apr '17

I'm trying to add a probe, by probe number, to an existing, running measurement, using curl, following the example and description on page 84 of the "RIPE Atlas API v2 manual". However, I'm getting an error message that does not clearly point me to the problem, and thus allow me to correct my error. Here's what I'm entering (with the <.> as placeholders, explained below) curl -H "Content-Type: application/json" -H "Accept: application/json" -X POST -d '{"probes":[{"action":"add","requested":1,"type":"probes","value":"<p>"}]}' https://atlas.ripe.net/api/v2/measurements/<m>/participation-requests/?key=< a> where: <p> is the number of the probe I'm trying to add, and I can access it at https://atlas.ripe.net/probes/<p> <m> is the measurement to which I'm trying to add it - it's a running measurement, and I can access it at https://atlas.ripe.net/measurements/<m> <a> is the API key, which is enabled and has "Update an existing measurement" granted The error I get back is: {"error":{"status":400,"code":104,"detail":"JSON parse error - No JSON object could be decoded","title":"Bad Request"}} In case it's relevant, I'm running curl 7.53.1 on Windows 10. Thanks in advance for any suggestions. colin
