Requesting Credits for Research
by Alex Gamero-Garrido 29 Jul '23

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?

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

Probe 2177 disconnected since Tuesday
by Werner Wiethege 20 Mar '20

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.
