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

Feature Request to consider: DNS response IP header
by Jen Linkova 22 Jul '19

22 Jul '19

Hello, I have a number of use cases when it would be very useful to have access to the IP header of the measurement response packets. In my scenario I'd like to see TTL/Hop Limit of packets received in DNS measurements. So I'm curious if anyone else think it would be a useful feature and if there is some demand for such a feature - maybe the Atlas team could consider implementing it? Thanks! -- SY, Jen Linkova aka Furry

Hello, I would like to take part at the ripe atlas grip. I applied already for a probe and still waiting for delivery since a long time. Does anyone have a probe which isn`t in use or would like to transfer? best regards Sascha Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Streaming API Losses
by Marcel Flores 28 Jun '19

28 Jun '19

Hi all, We've been exploring the use of the Streaming API to collect result stream data for a set of user defined measurements, in particular using the interface available in Cousteau. However, we've found that the Streaming API seems to be "lossy", with only a fraction of the results reported through the usual system making their way into the stream. I've not been able to find any sort of pattern on what does and doesn't make it through. Does anyone else have experience with this? Are there known limitations with the Streaming API? If so, has anyone worked out any clever workflows to accommodate? Thanks very much! -- *Marcel Flores, PhD* | Sr. Research Scientist research.verizondigitalmedia.com | AS15133 <https://www.peeringdb.com/asn/15133> p: +1 310.593.6880 e: marcel.flores(a)verizondigitalmedia.com 13031 W Jefferson Blvd. Building 900, Los Angeles, CA 90094

Filter for all results of a probe within a given timeintervall
by Lars Prehn 28 Jun '19

28 Jun '19

Hi everyone, I'm currently trying to retrieve ping and/or traceroute results for a specific probe in a given time interval via cousteau and/or the measurement API directly. It seems like I'm not clever enough to get it done. Is there a possibility to achieve this goal without iterating over each and every measurement to check whether or not the probes and the time match? Best regards, Lars

raspbian.net/raspbian.org ipv6 peering problems
by Thomas Schäfer 25 Jun '19

25 Jun '19

Hello, I am not sure if I am right here with my question. Does someone measurements to the server of "raspbian"? Their hoster (bytemark, iomart, zayo?) seems not to be able to establish correct peerings. At least the peering to AS3320 is broken. I already contacted 3320. They say zayo doesn't fulfill the minimum security requirements. Are more peerings broken? Regards, Thomas

When to consider a measurement finished
by Wouter de Vries 25 Jun '19

25 Jun '19

Hi all, I am currently trying to do some measurements according to the following steps: 1. create a one-off measurement 2. wait for it to finish, by periodically polling the msmid and checking the status. 3. fetch the results However, the system takes a pretty long time to set the status to finished, even when all results are already in (maybe 10 minutes?). What heuristics/method do you recommend to determine whether to consider a measurement as finished? One option I consider is to periodically fetch all results for a given msmid and checking if the number of results matches the number of probes assigned to the measurement. However, I suspect that causes a much higher load on the infrastructure. Best regards, Wouter de Vries

Probe off-line for 6 days due to bad firmware signature
by Novak Jirka 25 Jun '19

25 Jun '19

Hello, my probe 22424 is off-line due to bad firmware signature error. I try to boot it without USB stick many times, then i change the USB stick (replace the old one with new one), but it doesnt solve my problem. Could you help me? This is the information from my status page: Bad Firmware Signature What does this mean? The probe's firmware signature is wrong. How can I fix this? Power-cycle the probe and wait for a couple of hours. If probe doesn't come online you should try to reinitialise or even replace your flash drive. Please use the following procedure: 1. Unplug the probe from its power source 2. Remove the USB stick from the probe 3. Plug in the probe WITHOUT the USB stick 4. Wait for ten minutes 5. Insert the USB stick If it didn't help repeat these steps using another working USB stick that is at least 4GB in size. NOTE: This must be done on a network with working DHCP! It will NOT work if you have configured your probe to use a static IP address, because this mini-operating system does not have access to any statically configure IP addresses or DNS resolvers. If you have configured your probe to use a static IP address, the only thing you can do is move it to a network with working DHCP. When the probe is listed as "connected" again, it is safe to move the probe back to its original location. However, please note that we advise configuring your probe to use a static IP address only if you feel it is truly necessary to do so. Thx, Jiri

Hello, Is any body out there using "https://github.com/czerwonk/atlas_exporter" promethues exporter for exporting metrics from ripe atlas, started using it , wanted to know experience or best practices before spending more time on it. Only exporting ping metrics for now as explained in the article, any other metrics were tried and how were the results, any such help is appreciated :) Kind Regards, Kiran.
