Atlas F.ROOT ping
by Peter Gervai 09 Jan '14

09 Jan '14

Hello, Atlas helped me today first to see a hard-to-detect bug: F-root anycast algo works fine for v4 but fails miserably for v6, as instead of AMSterdam it sends all traffic to some remote island in the pacific. ;-) Seems to be the reverse true for M-root: ipv4 sends me off to nowhere land while v6 is great. A-root follows the F-suit. (C-root is not a good avertisement valie for Cogent, with v4 only address and considerable ongoing pkt loss.) Thanks! Peter

RIPE Atlas maintenance on Tuesday, 6 August
by Robert Kisteleki 06 Aug '13

06 Aug '13

Dear RIPE Atlas users, We'd like to let you know that we plan to perform scheduled maintenance on the RIPE Atlas central infrastructure on Tuesday, 6 August, for a couple of hours during the day. In this period, main features including the RIPE Atlas user interface (atlas.ripe.net), data downloads and measurement scheduling functions will be unavailable. Probes will continue to work and all results will still be collected or buffered; however, during the maintenance period you will be unable to log in to the website, manage your probes/measurements, or get to result data/visualisations. We apologise for any inconvenience this may cause. Regards, Robert Kisteleki

Registering a new probe...
by Chris Elliott 31 Jul '13

31 Jul '13

I have one probe (3690), and just received two new probes from Nathalie Trenaman, thanks to Bert Wijnen. However, either I'm just flat out missing something or the registration page is broken. I go here: https://atlas.ripe.net/register/ I ensure I'm logged in, and try to complete the registration process. No matter what, it always says: - There were some problems with your submission. Please see below However, nothing is highlighted or otherwise called out as an issue. I've tried various combinations in various fields, with no success. Here's one of the settings I've tried: - On what sort of network will you be installing the probe? * Residential/Consumer Business Network Educational Network IXP RIPE NCC Member (LIR) - Organisation Name * - What's the connection speed like on that network? * < 1 Mb/s 1-4 Mb/s 5-9 Mb/s 10-19 Mb/s 20-49 Mb/s 50-99 Mb/s 100-499 Mb/s 500-999 Mb/s > 1 Gb/s I don't know - AS Number - My network supports IPv4 - IPv4 Network Prefix - Please enter a valid prefix. - My network supports IPv6 - IPv6 Network Prefix - How did you receive your probe? * From conference/training From sponsor Other - Who is the sponsor? * - MAC Address - Location * <http://maps.google.com/maps?ll=21.351893,-102.718887&z=2&t=m&hl=en-US&mapcl…> Map data ©2013 MapLink - Terms of Use<http://www.google.com/intl/en-US_US/help/terms_maps.html> Map Satellite - I'm willing to keep the probe online 24/7 - I'm willing to make my probe visible to the public - I accept the rules of the game a.k.a. Pilot Service Rules<https://atlas.ripe.net/service-rules/> * Thanks for looking into this issue. Chris. -- Chris Elliott chelliot(a)pobox.com

HTTP or not HTTP?
by Stephane Bortzmeyer 31 Jul '13

31 Jul '13

I'm surprised to see in UDM documentation that you can do HTTP measurements: https://atlas.ripe.net/doc/udm#http-http6 But I do not find this option in the "Choose a measurement" menu of the Web interface. And it is not documented in the REST API: https://atlas.ripe.net/doc/measurement-creation-api/ > type: One of ping,traceroute,dns or sslcert So, can we do HTTP measurements with the Atlas probes?

Outdated documentation to delete
by Stephane Bortzmeyer 30 Jul '13

30 Jul '13

IMHO, the "mechanize" example in <https://atlas.ripe.net/doc/code#access_from_scripts> is useless now that we have an API and should be deleted.

Spoofing the source IP address from a probe?
by Stephane Bortzmeyer 30 Jul '13

30 Jul '13

I read in the interesting <http://www.internetsociety.org/blog/2013/06/can-we-stop-ip-spoofing-internet> about BCP38 (anti-spoofing): > Another possibility that was suggested is using RIPE Atlas probes to > probe network capabilities (or shall we say incapabilities?). AFAIK, Atlas probes cannot currently perform these tests, am I correct?

Re: [atlas] Spoofing the source IP address from a probe?

Hi, Probably we don't need to spoof all address space, instead only if spoofing enabled just spoof to some predefined address range.

Re: [atlas] Outdated for more than one day?
by Fred Grayson 28 Jul '13

Hello, The probe ID is 10156. It is attached to a third interface on my router. The graphs have been stalled for the last four days. The probe went online on June 26 and all was well until this happened on July 24. Thanks for looking.

Outdated for more than one day?
by Fred Grayson 27 Jul '13

27 Jul '13

Hello, Recently, all Built-in-Measurments for my probe began showing "Outdated for more than one day" and none of the graphs are current, most show some white space at the far right hand side. My Total Uptime: 99.56% (31d, 22h, 30m) and I have power cycled the device twice trying to solve the problem. Any ideas on how to fix this will be appreciated. Thanks, FG

Ping Fails (ns.ripe.net)
by AlbyVA 23 Jul '13

23 Jul '13

In reviewing My Probe stats, it appears that (ns.ripe.net) was once able to ping the server, but now it appears to be failing. All my other ping stats under My Probe show successful pings to other servers, but for some reason ns.ripe.net is failing. Does anybody have a suggestion of what might be going on, since ping is working to all the other servers. -Alby
