29 Jul '23

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.

Notification for probes going down for extended period??
by Geert Jan de Groot 04 Jan '22

04 Jan '22

Hi, I have been hosting probes for many years and, judging by the traffic seen, they have seen a fair amount of use, which is good. Despite being on a "home network", I was able to get a small subnet so the probes could run without NAT state nastyness and all. Unfortunately, the ISP providing home connectivity is changing. They used to be innovative, offering IPv6, subnet and lots of features. However the mother telco decided that innovation was bad and is changing the service offering, killing innovative services one by one. Today I received notification that the subnet the probes live on, will be de-activated on Jan 11. I've cancelled my subscription with said ISP on Jan 13 and the house will be on a different ISP then, unfortunately the new ISP is planning to provide subnet service but is in the process of setting things up and cannot provide subnet service today. What is the protocol for signalling "this probe is down and that may be for quite a bit"? And what is the protocol for signalling "this probe is now on a different topology, is no longer on AS3265 and network performance is different"? (I guess several others will have this question, answers on list please) Geert Jan

v1 Prove #266 gone offline
by Andreas S. Kerber 04 Jan '22

04 Jan '22

Hi, our v1 probe #266 has gone into a boot loop, loosing/reconnecting network link every few seconds. Is there troubleshooting advice for a v1 probe doing that? Already tried on a number other USB feeds and different switches. Andreas

NanoPi NEO Plus2 won't connect
by Marty Strong 28 Dec '21

28 Dec '21

Hi all! I moved house at the end of June and only recently got round to plugging my NanoPi NEO Plus2 probe #50010 in. It doesn't seem to connect, not even getting a DHCP lease. Is there any way to debug what's wrong with it? https://atlas.ripe.net/probes/50010/ Thanks, Marty

Announcement regarding the recently discovered log4j vulnerabilities
by Johan ter Beest 22 Dec '21

22 Dec '21

Dear RIPE Atlas probe and anchor hosts, We would like to share some information in light of the log4j issues that were recently made public. After an extensive investigation of our systems, we have determined that both the RIPE Atlas probes and the RIPE Atlas anchors are not vulnerable to the recently discovered log4j vulnerability. More information can be found in the official announcement: https://www.ripe.net/publications/news/announcements/log4j-zero-day-vulnera… We wish you happy holidays and happy measuring :) Kind regards, Johan ter Beest RIPE Atlas Team

v3 probe has gone offline and can't be revived
by Peter Gutmann 21 Dec '21

21 Dec '21

My v3 probe took itself offline earlier today and attempts to get it back online again haven't worked, after booting it settles into a state where there's no ethernet connection to the router it's attached to, the Power LED is on (obviously), Internet is off, WiFi is blinking slowly, Ethernet is blinking quickly, and WPS is on. Trying to factory reset it has no effect. Does anyone have any ideas on where to go from here?

a sweet old v1 probe, 2285, in a hard to access (due to covid) place died 19 months ago. i want to swap in a v3, 25898, this weekend. i know i could create a new entry, but how do i delete the old; or better yet, move the data from old to new? stop laughing. :) randy

RIPE Atlas VM Anchors IPv6 only support?

IPv6 is not a requirement if not used within the applying host ASN. Only an unfiltered public IPv4 address is. What about the reverse situation? ↪ I.e. the host ASN applying for hosting a VM Anchor is an IPv6-only ASN. Not utilizing IPv4 in the ASN. Therefore not able to provide an unfiltered IPv4 address to the VM? To my current understanding, the latter example is an instant disqualification if applying for hosting a RIPE Atlas VM Anchor? /Chriztoffer
