Probe DHCPv6 support
by Aleksi Pirttimaa 19 May '23

19 May '23

Hi! I recently received my v4 probe and I'm very happy with it. But unfortunately it doesn't support DHCPv6. I present a practical reason for implementing a DHCPv6 client on the probe. You see, my ISP doesn't send router advertisements with the prefix for stateless autoconfiguration set, and instead DHCPv6 must be used. I believe their decision could have something to do with the fact that the regulating body here requires ISP's to prevent IP address spoofing in consumer plans. And to meet that requirement my ISP may be using a feature similar to Cisco's IP source guard, where switch ports and/or mac addresses are passively associated to leased ip's or prefixes, breaking SLAAC. Unfortunately they hate letting consumers talk with their engineers so it's difficult to speculate this further. For now, I've put a stateful firewall appliance in front of the probe which provides SLAAC, it works just fine. Do you think a DHCPv6 client should be implemented?

Meta-information dumps for built-in measurements?
by Vasileios Giotsas 09 Nov '20

09 Nov '20

Is there any repository like https://ftp.ripe.net/ripe/atlas/measurements/ that contains meta-information about built-in RIPE Atlas measurements (the above repository contains meta-information only for public measurements)? I couldn't find anything similar in the new FTP repository at https://data-store.ripe.net/datasets/atlas-daily-dumps/ I guess using the API is an alternative but it would be more convenient to have such dumps Thanks, Vasileios

RIPE Atlas Software Probes
by Philip Homburg 22 Jun '20

22 Jun '20

Dear colleagues, We are glad to announce that, after several months of development and testing, we are now accepting applications for RIPE Atlas software probes. With several different installation options to choose from, software probes provide future hosts a whole new way to get involved with RIPE Atlas. For more details, see our new article on RIPE Labs: https://labs.ripe.net/Members/alun_davies/ripe-atlas-software-probes Kind regards, Philip

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

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
