by Vesna Manojlovic 26 Feb '21

26 Feb '21

Dar all, You're invited for an open discussion with the RIPE NCC about the Internet in Turkey! We are hosting a RIPE NCC Open House for our members and other Internet stakeholders in Turkey on Wednesday, 24 February at 11:00 - 12:30 UTC and invite you to join the discussion. The RIPE NCC Open House is a ninety minute remote session where RIPE NCC staff, community members and industry experts can meet up and share insights, feedback and support. https://www.ripe.net/participate/meetings/open-house This session is focusing on the Turkish Internet community. We will be discussing various topics including: * The state of the Internet in Turkey and across our service region * How RIPE NCC tools and measurements can help operators (RIPE Atlas, RIPEstat, RIPEIPmap, etc.) * Improvements that the RIPE NCC can make to help operators in Turkey * IPv6 deployment * Local community development and the support available from the RIPE NCC Want to join in? Register for the RIPE NCC Open House https://meeting-registration.ripe.net/meeting-pub/registration?0&meetingId=… Looking forward to seeing you online!

New on RIPE Labs: RIPE Atlas Big Data is Back
by Alun Davies 23 Feb '21

23 Feb '21

Dear colleagues, At the beginning of the year, RIPE Atlas users started encountering delays in data retrieval and an overall drop in the responsiveness of the system. With service having gone back to normal earlier this month, we take a look at what caused the problem and what we're doing prevent it from happening again: https://labs.ripe.net/Members/paul_de_weerd/ripe-atlas-big-data-is-back Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

Re: [atlas] [mat-wg] RIPE Atlas testing of reserved IPv4 addresses
by Robert Kisteleki 18 Feb '21

18 Feb '21

Dear All, A little bit of poking since there were no reactions to this question on the MAT mailing list. Before embarking on evaluating what it takes for RIPE Atlas to contribute to this, I'd like to ask for some input from the community; is this something we should spend energy on? More specifically, would it be worthwhile for us to spend time on evaluating the cost of / implementing such measurements in RIPE Atlas?

RIPE Atlas Measurements packets sent number not always 16
by Debora Marettek 17 Feb '21

17 Feb '21

Dear RIPE NCC, for my ping measurements, I incremented the number of sent packets to 16. Now I noticed that in the measurement with the ID 28779821, the probes didn't always send 16 packets, sometimes, albeit rarely, only 7 or 3. Below you see an extract of the packets_sent data of Probe 52673. Now I wanted to ask what could possibly be the reason for that phenomena. Kind regards, Debora Probe: 52673 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 5, 1, 9, 16, 16, 16, 14, 16, 16, 16, 16, 8, 13, 6, 7, 6, 6, 16, 16, 12, 16, 16, 16, 16, 16, 10, 11, 10, 7, 6, 16, 4, 16, 16, 16, 16, 4, 7, 15, 6, 9, 12, 11, 7, 8, 11, 6, 5, 13, 13, 13, 5, 10, 16, 16, 7, 7, 9, 7, 7, 7, 9, 16, 16, 11, 4, 7, 16, 7, 2, 8, 16, 4, 6, 8, 16, 7, 8, 6, 5, 8, 8, 9, 8, 7, 4, 3, 10, 1, 2, 11, 6, 16, 8, 12, 6, 11, 10, 11, 8, 12, 12, 12, 11, 8, 16, 6, 5, 5, 9, 10, 6, 10, 7, 9, 10, 9, 11, 8, 8, 11, 7, 12, 7, 11, 9, 13, 2, 10, 12, 10, 7, 9, 16, 13, 5, 4, 7, 8, 6, 5, 7, 6, 7, 9, 9, 9, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 4, 9, 4, 6, 8, 6, 11, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, <https://atlas.ripe.net/measurements/28931367/>

Re: [atlas] Updating probe ssh pub keys via API PUT/PATCH requests
by Chriztoffer Hansen 15 Feb '21

15 Feb '21

Hi RIPE Atlas, Was reading through the documentation yesterday... Is there a specific reason why it is NOT possible to update probe (ssh) pub keys via authenticated API PUT/PATCH requests? https://beta-docs.atlas.ripe.net/apis/metadata-reference/ -- Best regards, Chriztoffer Hansen

Measurement Result Broken
by r.sommese＠utwente.nl 10 Feb '21

10 Feb '21

Hi everyone, I am getting trouble getting results for ping measurements. Looking at the web portal and JSON results, they are both empty. Measurement ID: 29049476 I also checked from the account of a colleague, same story. There is something broken in the pipeline? Best, Raffaele Sommese

Hi All, Can't seem to find a way to just mark a long dead probe as such. Thanks, Kyriacos

atlas probe down : ID 35603
by MAYER Hans 08 Feb '21

08 Feb '21

Dear All, Our Atlas probe with ID 35603 is down since about 6 days. It’s a V3 probe. Model: TL-MR3020(UN) Ver: 1.9 ; S/N: 2176197008302. When I realised it this atlas probe was not ping-able. ( due to a power outage ) I followed the instructions https://labs.ripe.net/Members/philip_homburg/troubleshooting-ripe-atlas-pro… with solution 1. Unfortunately it didn’t work. During the time without USB stick the probe was on the network reachable, getting the IP from DHCP. But later on, it wasn’t ping-able. So I tried solution 2. I took a different USB stick as described. After a while the probe is now ping-able. ( 2001:628:21f0:911:c225:e9ff:fea8:6530 , 147.125.100.34 , DNS name: ripencc.iiasa.ac.at<http://ripencc.iiasa.ac.at> ) But when I go to https://atlas.ripe.net/probes/35603/ I see it is offline. The web page says „no flash drive“ and „trying to connect“. What else can I do ? It seems, that the TP-Link device itself isn’t broken. Shall I try with a different USB stick. (a third one) I took a 64MB USB stick. Was this maybe too big ? I saw the original stick had only 1 MB. The documentation says it should have at least 4GB. Any ideas ? Any feedback is welcome.

querying the config
by Randy Bush 04 Feb '21

04 Feb '21

howdy so i wanted info about a probe's config, specifically what dns resolver(s) it is using. i could not figure out how to do this. assuming it was a lack of clueons, i asked a friend with far deeper atlas fu. they said such queries are not available. really? [ yes we have bright ideas on how to discover this indirectly by mining past data ] but really? randy
