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

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 07 Jul '21

07 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 06 Jul '21

06 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

Resolves AAAA Correctly, Doesn't Resolve A - best way to resolve this?
by Peter T Garner 28 Jun '21

28 Jun '21

I've been having a few problems setting up my software probe, but this has now almost stabilised. It's been quite an education in DNS setup! My problem now is that my probe General Information is reporting "Resolves AAAA Correctly, Doesn't Resolve A, IPv4 Stable 1d, IPv4 Works, Software IPv4 RFC1918, IPv4 Capable" but I can't seem to fix the "Doesn't Resolve A" problem: is there anything specific that I can try from the command line to diagnose this? FWIW, all other traceroutes, pings, digs etc on the box seem to be working.

IPv6-renew
by Marco Davids (IETF) 22 Jun '21

22 Jun '21

Hi, Whenever my network get's a different IPv6-prefix from my provider (which happens every now and then), the probe is flagged down in the dashboard. The reason seems to be that RIPE Atlas probes are unable to renew their (SLAAC?) IPv6-addresses when needed. Only solution is a powercycle. Is this a flaw, or is it by design? -- Marco

SLAAC works as designed with IPv6 renumbering. slaac - being stateless 'n all - was not designed with flash renumbering in mind because flash renumbering needs some degree of state synchronisation on all devices on the path between the provisioning system issuing the prefix and the end device. So in this sense it is a protocol issue, albeit an issue that was outside the design scope of the protocol. > Imagine if the mobile operator swapped your mobile phone number midstream. mobile phone numbers are stateful. You don't need to change phone number every time you're handed off to a different cell. Nick

Is there a definitive guide to firewall rules?
by Peter Garner (iPad) 21 Jun '21

21 Jun '21

Noob question. I set up a software probe a couple of days ago on a Linux box that uses Universal FireWall (UFW). I've no problem with the required internal ports and the probe seems to be working as intended but would like to know if there's a definitive list of ports and protocols that I can apply to get the maximum benefit to the data?
