Hi folks, My name is Alexander Gamero-Garrido and I'm a 5th year PhD student at CAIDA, UC San Diego. We're soon launching a large traceroute campaign for research and could use your generous donation of credits. We'll need about 150 million credits, but any partial amount that gets us closer to that goal is welcome and greatly appreciated. My account is agamerog at eng.ucsd.edu Thank you, Alex -- *Alex Gamero-Garrido* *PhD Student, Computer Science* Web: cseweb.ucsd.edu/~agamerog Center for Applied Internet Data Analysis (CAIDA) San Diego Supercomputer Center UC San Diego Pronouns: He/Him/His <https://inboxwhenready.org/?utm_campaign=signature&utm_medium=email&utm_sou…> I'm using Inbox When Ready <https://inboxwhenready.org/?utm_campaign=signature&utm_medium=email&utm_sou…> to protect my focus.

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?

Is there a procedure to move a software probe to a new device
by Peter Garner (iPad) 01 Feb '22

01 Feb '22

Noob question. I set up my software probe on a Debian 10 box which has quite a few small servers on it. However, I intend to move it onto a Raspberry Pi, so I was wondering if there's a specific procedure to follow to preserve existing settings? Only the internal IP address will change; the external remains the same.

Representative probe sets in eyeball networks by country
by Bart van der Sloot 21 Jul '21

21 Jul '21

Hi RIPE Atlas community, Can anyone recommend/provide predefined probe sets which provide a fair representation of the eyeball networks in a country, e.g. “10 probes in each of the Top 5 eyeball networks in France” – and preferably probes that are “in” these eyeball networks (and/or close to their interconnection routers – where they peer or connect to their Transit providers, decreasing the dependency on last mile access and in-home networks) and probes that have a high uptime? Thanks in advance for your reactions!

anchor disk recovery
by Matthieu Herrb 20 Jul '21

20 Jul '21

Hi, after a power outage, our anchor got its grub.cfg file corrupted. I managed to use a .rpmsave boot.cfg that was present on the disk and boot into the recovery kernel. >From here the anchor is alive again on the management interface at https://atlas.ripe.net/probes/7000/ but I guess it's still in a unstable state. What is the procedure to actually repair the installation ? Should I re-install it from the USB image, or is there something else I can do remotely ? x -- Matthieu Herrb

Latest data point shown is from 2021-07-16 10:43 UTC
by Thomas Schäfer 19 Jul '21

19 Jul '21

Hi, I run two independent software probes. Looking at the graphs "Built-ins" I get the orange text: "Latest data point shown is from 2021-07-16 10:43 UTC" It only happens on the software probes. My hw probe seems to run without that problem. All three probes are online "Your probe is currently connected" Regards, Thomas

Unable to create measurements in RIPE Atlas
by Salvador Bertenbreiter 12 Jul '21

12 Jul '21

Hi guys, I hope you're doing well. I am preparing an article about latency in LATAM and I would like to use RIPE Atlas to gather some data, unfortunately, I'm not being able to create my first measurement, I completed the three first steps: 1) Ping x.x.x.x 2) Selected 10 probes in Peru 3) Choose the time interval But when I click on the Create My Measurement(s) button nothing happens, I don't even receive an error message about a missing or wrong field. Any idea what could be happening? Are you able to create measurements without issues? Thank you Best regards, -- Salvador Bertenbreiter (+51) 947 145 352

Getting RRSIG records when do bit is set
by pravicha 06 Jul '21

06 Jul '21

Hello, When I set the do bit in dig, I get back RRSIG records associated with the Query Type, but I don’t get the RRSIGs when I create a measurement with do bit set in Ripe Atlas. Can I replicate the same behavior in RIPE atlas? Thanks

Is there a way to find the resolver used by the probe?
by pravicha 05 Jul '21

05 Jul '21

Hello, I’ve been trying to get dns measurements for a couple of domains over different regions using atlas probes. Is there a way to find the resolver’s IP used by the probes when use_probe_resolver is set to true? Thanks
