anchor on a /32 network with on-link routing ?
by Matthieu Herrb 24 May '20

24 May '20

Hi, here at Tetaneutral.net we purchased an anchor with the idea to host it in our network. For IPv4 We are using /32 addresses everywhere, and do the routing by setting the 'on-link' flag on the default route. This configuration doesn't seem to be possible through the management interface. It complains that the gateway is not no the same network as the host and provides no way (as far as I can tell) to setup the 'on-link' flag. Apart from inserting another router in front of our anchor to let it use a narrower prefix, is there a way to set it up ? Or can this be considered for the future evolutions of the anchor software ? Thanks in advance. -- Matthieu Herrb

running a probe via LTE access
by Thomas Schäfer 21 May '20

21 May '20

Hi, Has anybody experience with running a probe via LTE? I see only a little amount if I use the tags 4g or LTE, together with IPv6 as requirement, just less than 10. What is the monthly data volume you have? Is it a big problem if I run in a speed limit of 32kbit/s? Regards, Thomas

One of my hosted probes don't accept measurements
by Evgeniy S. 07 May '20

07 May '20

Dear RIPE guys, one of probes hosted by us https://atlas.ripe.net/probes/35439/ shows as connected and good to go, but when I create any measurements with this ID I see "1 Requested / None yet Actually Participating" Please advice what's wrong with it and how to troubleshoot? -- With regards, Eugene Sudyr

It seems there is currently no way to set the AD bit in DNS queries? (Through the API, we can only control RD, CD and DO bits.)

Probe 2177 disconnected since Tuesday

20 Mar '20

The green light is on and the orange light flashes but I don't see any network traffic from it. The port LED on the switch lights up when the cable is plugged in. I have disconnected it and plugged it in again after a few hours but that didn't change anything. Werner

Software probe using port 8080
by Paul Eagles 13 Mar '20

13 Mar '20

Hi, Is there any way to change the ports that the software probes use? Port 8080 is used by the probe which conflicts with another piece of software I wanted to use. Looking in the processes I saw this: atlas 843 0.0 0.2 50348 5992 ? S 10:15 0:00 /usr/bin/ssh -o ServerAliveInterval 60 -o StrictHostKeyChecking yes -o UserKnownHostsFile /var/atlas-probe/.ssh/known_hosts -R 50948:127.0.0.1:2023 -L 8080:127.0.0.1:8080 -i /var/atlas-probe/etc/probe_key -p 443 atlas(a)ctr-fsn01.atlas.ripe.net KEEP I had to kill the PID in order to run the other software I need so at present this new software probe is down. I'd like to start it up again but can't unless I can control which port the SSH tunnel is using. Thanks, Pauil.

Software probes offline since updating to 5010-3
by Paul Eagles 12 Mar '20

12 Mar '20

Hi all, About an hour ago I updated my 4 software probes (1000136, 1000137, 1000149 & 1000177) to 5010-3 from 5010-1 and they're all still showing as offline. For each probe I went through and updated the keys within a minute or so of the installation finishing so I don't think that's the problem. It shouldn't be an internet connection issue, they're all using the same connection as they were prior to the update and prior to the update all 4 probes were connected OK. Plus I have a physical probe at home in the same location as one of the software probes and that physical probe is showing as online. One of the software probes has been rebooted but that didn't seem to make any difference. Checking the running processes on the host everything appears OK, I see 2 instances of the ATLAS binary running. Am I missing something or just being impatient? Cheers, Paul.

(not) disconnected probes
by Romain Fontugne 11 Mar '20

11 Mar '20

Hi, I found that the following probes are reported disconnected for several hours a day, more or less at the same time, but all their built-in measurements are there and seem normal: https://atlas.ripe.net/probes/32639/#!tab-network https://atlas.ripe.net/probes/28818/#!tab-network https://atlas.ripe.net/probes/19107/#!tab-network https://atlas.ripe.net/probes/14831/#!tab-network https://atlas.ripe.net/probes/11982/#!tab-network These probes are in different ISPs and locations in Japan. Any idea why this is happening? something funky on the controllers side? Thanks, Romain

New on RIPE Labs: What’s the Deal with IPv6 Link-Local Addresses?
by Philip Homburg 11 Mar '20

11 Mar '20

Dear colleagues, Stephen Strowes, Emile Aben and I published a new article on RIPE Labs on how link-local addresses in IPv6, and specifically the '%eth0'-part of link-local addresses, can have an impact on RIPE Atlas measurements. https://labs.ripe.net/Members/philip_homburg/whats-the-deal-with-ipv6-link-… We think this will be an interesting read for network operators and others who are using RIPE Atlas measurement data or are interested in IPv6. Kind regards, Philip Homburg RIPE NCC

Broken traffic graphs in latest firmware (5010)
by Philip Homburg 10 Mar '20

10 Mar '20

Hi, A change in the RIPE Atlas probe code to make reporting traffic statistics optional in software probes (and disabled by default) has the unfortunate side-effect that reporting of traffic statistics is now disabled on Version 3 and Version 4 hardware probes, as well as all anchors. This change was rolled out in firmware version 5010. Unfortunately, this effect was not spotted during testing. We will roll out a new firmware release that corrects this issue in coming weeks.

check dns64/nat64 behavior ?
by Thomas Schäfer 21 Feb '20

21 Feb '20

Hi, is there a simple way to check the reachability of IPv6 targets by probes behind NAT64? e.g. If I try to ping www.t-online.de with Adress Family IPv6 I get immediately the error " No IPv6 address found for target" instead of "measuremnet created". Same problem exists for DNS measurements. Regards, thomas

Probes were incorrectly not tagged with the stability tags
by Chris Amin 21 Feb '20

21 Feb '20

Dear colleagues, Over the past month there have been issues with the "system-ipv[45]-stable-{1,30,90}d" tags, which were not applied to many of the probes that should have had them. This was caused by accidental data format changes from a backend migration. The issue should now be fixed, so probes will have the correct tags applied. If you notice any persisting issues then please let us know! Apologies for any inconvenience. Kind regards, Chris

atlas probe down
by MAYER Hans 19 Feb '20

19 Feb '20

Dear All, Our Atlas probe with ID 35603 is down since Wednesday exactly 12:00 LT. I unplugged power and powered on, but no success. After power on some LED's are blinking. Finally the power LED stays on and the LED next to it is blinking. But I can't ping this probe. Either on IPv4 nor on IPv6. We got this probe in summer 2018. So I can't believe it's EOL. Any ideas what I can do ? Kind regards Hans --

Can I issue a traceroute measurement with multiple targets?
by Vasileios Giotsas 11 Feb '20

11 Feb '20

If I have 100 IPs to target from a single probe, is it possible to create a single measurement with 100 targets similar to how I'd do if I wanted to target a single IP from 100 probes? I've read through the Atlas API documentation and couldn't find anything like that but it looks like some of the built-in measurements do that. Thanks, Vasilis

Atlas API stream broken?
by Teun Vink 10 Feb '20

10 Feb '20

Hi, Since ~13.30h CET this afternoon our Atlas data stream subscriptions (using the ripe.atlas.cousteau python library) stopped receiving updates. Earlier today we (at 11.27h) observed some issues with the backend where we received redis errors, which were resolved at ~12.09h CET. I heard these were related to some firewall issues, could these problem be related? Regards, -- Teun Vink BIT | teun(a)bit.nl | +31 318 648 688 KvK: 09090351 | GPG: 0xFC8B25D6 | RIPE: TEUN-RIPE

Planned Atlas downtime on 29 January
by Robert Kisteleki 06 Feb '20

06 Feb '20

Dear RIPE Atlas users, Please be aware that we plan to do maintenance work in the RIPE Atlas core infrastructure two weeks from now, on Wednesday 29 January, between 9:00-12:00 CET (Amsterdam time). The RIPE Atlas website, UI and API will be unavailable in this period. The probes should remain connected and results will be collected normally, although during this period they can only be accessed real-time via the streaming service. Apologies for the inconvenience this may cause. Regards, Robert Kisteleki

Using Atlas for Monitoring of Anycast DNS
by Klaus Darilion 20 Jan '20

20 Jan '20

Hello! I want to restart this old thread and ask for available tools. For our Anycast DNS cloud, I want to measure the "performance", ie the RTT from Atlas probes. 1. Create measurements (I can do that already ;-) 2. Analyze this measurements: - fetch measurement - analyze the probe locations (ie. country, continent) - create reports with average RTT from certain countries and continents This second step I have partly in old scripts using influxdb and grafana dashboard - but that was a proof of concept with bad code. So, before starting coding from the base - are there some available scripts which can do the second part? Is https://github.com/RIPE-NCC/ripe.atlas.sagan still the way to go for measurement processing or are there meanwhile some better/smarter libraries? ie something for php?
