Local resolver for one off DNS measurement
by Rob Turner 15 Jul '14

Hi is it possible to perform a one off DNS A record test that uses each probes local resolver? I think this would be handy to test DNS propagation. Rob.

Solido Networks ApS has joined RIPE Atlas anchors
by Lia Hestina 14 Jul '14

14 Jul '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 dk-blp-as59469 and it is hosted by Solido Networks ApS in Ballerup, Denmark. Our congratulations to Solido Networks ApS! This is the first anchor in Denmark. In our announcement about last week's new anchor, there was a typo in the company name and we would like to apologise for this. The anchor, cz-prg-as2852, is hosted by CESNET, z. s. p. o. in Prague, Czech Republic. 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: https://atlas.ripe.net/anchors/list/ Learn more about RIPE Atlas anchors: https://atlas.ripe.net/about/anchors/ Thank you for participating in RIPE Atlas!

Atlas nagios tools
by john 12 Jul '14

12 Jul '14

Hello all, i would like to introduce a tool[1] i have been developing on and off for a bit of time. its uses the atlas latest call[2] and sagan[3] to preform nagios checks based on measurement results. it supports checking a wide range of ssl, dns and http parameters which i have tried to document on github[1]. it also supports checking ping however i think it is better to use the atlas status checks[4][5] for this. The git hub repo contains some sample nagios configs which can be seen in action at https://icinga.johnbond.org/ (ripeatlas/ripeatlas). at $dayjob we dont use nagios/icinga so this is not well tested and one should expect some bugs. if you dare inspect the source you can definitely expect spelling mistakes and hacks. Thanks to Iñigo Ortiz de Urbina and Wolfgang Nagele for patches. Also thanks to Daniel Quinn and Philip Homburg for working with me integrating some changes to sagan. feedback, criticism and patches most welcome John *as http is a restricted measurement this has received little testing [1]https://github.com/b4ldr/atlas [2]https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-latest-res… [3]https://github.com/RIPE-NCC/ripe.atlas.sagan [4]https://labs.ripe.net/Members/suzanne_taylor_muzzin/introducing-ripe-atla… [5]https://github.com/RIPE-Atlas-Community/ripe-atlas-community-contrib/blob…

Fwd: monitoring RFC1918 IPs
by Hendrik Visage 07 Jul '14

07 Jul '14

Hi there, I'd like to monitor a couple of internal routes from one of my probes, but I get this error: Ping: Field 'target' : Measurement target "10.23.0.1" is invalid. Is that a limit somewhere? possible to relax that for probes owned/operated by me? Thanks HEndrik

How to find the correct ASN of a probe?
by Eravuchira, Steffie Jacob 07 Jul '14

07 Jul '14

Hello, The RIPE Atlas probe API [1] says that the probe with ID 14468 belongs to the ASN 6871. As per the RIPE stat API [2], the holder for ASN 6871 is PlusNet PLC,GB. I run a traceroute measurement from the same probe (Probe ID 14468) and the IP address of the second hop ICMP response is "86.4.10.1". But the RIPE stat API [2] shows that "86.4.10.1" belongs to the prefix announced by ASN 5089, NTL Virgin Media Limited,GB. Could someone tell me how I can find the correct AS which the probe belongs to? [1] https://atlas.ripe.net/api/v1/probe/?id=14468 [2] https://stat.ripe.net/ Kind Regards, Steffie

Probe connectivity status update interval
by Ondřej Caletka 04 Jul '14

04 Jul '14

Hello list, yesterday, we've deployed IPv6 in the network probe #16666 is located. The probe obtained its address via SLAAC and is world-pingable, however the Atlas system still haven't recognized the probe has IPv6 connectivity. When scheduling IPv6 UDMs for this probe, they are stuck in state "Scheduling" - see UDM #1694838 or #1694575. I guess that the system avoids scheduling IPv6 measurements to probes without IPv6 connectivity. How often is the connectivity status updated? Should we replug the probe to update its status? Cheers, Ondřej Caletka

tracing from anchor nodes
by Klaus Darilion 02 Jul '14

02 Jul '14

Hi! According to DNSMON [1] r.ns.at IPv4 is not reachable from us-bos-as11488. Are there any tools available to analyse the problem from the anchor? E.g. performing a traceroute from the respective anchor node? Thanks Klaus [1] https://atlas.ripe.net/dnsmon/group/at.?dnsmon.session.color_range_pls=0-66…

Paris-traceroute variations
by Juan Antonio Cordero Fuertes 30 Jun '14

30 Jun '14

Not sure this is the right place to ask this... sorry if it is not. I'm trying to configure Paris-traceroute measurements, and it is not clear for me what is the meaning of the *paris* parameter. In https://atlas.ripe.net/docs/udm/ it is said that it corresponds, for values from 1 to 16, to "the number of variations to be used for a Paris traceroute <http://www.paris-traceroute.net/>". What is this? Does it correspond to the number of initial probes to be used by paris-traceroute? I am unable to figure it out from the RIPE Atlas docs... any indication would be appreciated. Thanks, Juan Antonio Cordero
