Letsencrypt certificates on anchors
by Anand Buddhdev 13 Dec '19

13 Dec '19

Dear colleagues, Some time ago, there was discussion on this list about deploying Letsencrypt certificates on anchors. We had said we would investigate the possibility of doing this. We are pleased to report that we have worked out how to do this seamlessly. Early next week, all RIPE Atlas anchors will switch to Letsencrypt certificates. Note that we will re-use the existing keys on the anchors to request the Letsencrypt certificates. The TLSA records of all anchors are pinned to these private keys, and so they will not change. Regards, Anand Buddhdev RIPE NCC

Hi, If someone is planning to host a VM anchor, what are the security measures that RIPE Atlas can provide? For example, protecting the VM from being compromised by an attacker. Any information about this is highly appreciated because the plan is host several anchors. Thanks, Rami

Probes connected to 4G/LTE
by Ponikierski, Grzegorz 06 Dec '19

Hi all! I'm thinking about becoming ambassador to deploy more probes in Poland including rural areas where sometimes the only option to get access to the Internet is 4G/LTE. I'm interested what is your experience with 4G/LTE and Atlas probes. What tags you use to mark them? How stable they are? What RTT you see to first and second hop? Regards, Grzegorz

Long measurement delays
by Steve Gibbard 30 Nov '19

30 Nov '19

Hello, Atlas crew, I’ve been seeing delayed query responses to one-off measurements since November 22, with the exception of November 25. For www.globaltraceroute.com, which attempts to get responses for 90 seconds after submitting a query (and is usually fairly successful), this has meant a failure rate of 61% on average for those days, and as high as 83% on one of the days. I haven’t been tracking how long it does take for a response to come in in those cases, but my most recent test measurement, measurement ID 23502037, is still not returning any data an hour and 40 minutes after submission. My request format as a Python string is "https://atlas.ripe.net/api/v2/measurements/%s/latest/?key=%s" % (measurement_id, key). For these failures I’m receiving an empty list, so it looks like this might be something different than the “synchronizing” issue people were complaining about over the last few weeks. Trying to access that measurement via the Atlas Web UI, if I go to the “latest results” tab I get a spinning progress wheel, seemingly forever. I haven’t been tracking the Atlas “consumption delay” along with the results, so I’m not sure what it’s looked like during most of the failure periods. I checked at the time I submitted measurement 23502037 and it showed as green, although it’s showing as yellow now. Thanks for any help or attention you can provide on this. -Steve

Measurements "synchronizing"
by Stephane Bortzmeyer 30 Nov '19

30 Nov '19

It seems that, today, when querying the API about an existing measurement, I always get: {'id': None, 'name': 'synchronizing'} Which I've never seen. (Measurement #23238335 but it's not the only one.) A recent change? A temporay problem?

Unable to set probe location to Hong Kong
by Ponikierski, Grzegorz 28 Nov '19

28 Nov '19

Hi all! I was wondering why I see more probes in Hong Kong marked as Chinese probes. For test, I tried to set location of my probe to Hong Kong and even if I put location pin on map in the middle of Hong Kong it still ends assigned to China. Are we still able to assign RIPE Atlas probes to Hong Kong? If not, then what about probes which are still assigned to Hong Kong? How to reliably get via API list of probes located in Hong Kong? Should we parse geo coordinates and use 3rd party libraries to figure out where probe is really located? Regards, Grzegorz

Finding the NSID in the measurement results

Error: No suitable probes and delayed results
by Moritz Muller 03 Oct '19

03 Oct '19

Hi, In our experiment we’re trying to assign certain probes to a ping measurement but until now we always get the error message "NO SUITABLE PROBES”. According to the documentation, this is a sign that a probe might not have enough resources. However, when I check on the measurement a few hours later I do see results, but its state is still "NO SUITABLE PROBES”. See https://atlas.ripe.net/measurements/23016956/#!probes Is that a common problem when selecting certain probes for measurements? Moritz

DNS issue with Atlas or with the ISP?
by Stephane Bortzmeyer 09 Sep '19

09 Sep '19

RIPE Atlas Web site displays a lot of "undefined" for the tests in AS 3125. See for instance <https://atlas.ripe.net/measurements/22766270/#!probes> or <https://atlas.ripe.net/measurements/22766942/#!probes> But the DNS resolution from this AS seems to work. Checking the raw results in JSON, I see that we have a lot of failures on one IPv6 resolver: "dst_name": "fe80::a63e:51ff:fe77:e26", "error": { "socket": "connect failed Invalid argument" }, We do not see such IPv6 problem in other AS (see for instance <https://atlas.ripe.net/measurements/22766995#!probes>) I assume that the "connect failed Invalid argument" is the fault of the ISP, which advertises a wrong DNS resolver? Or is the Atlas probe unable to query link-local addresses for DNS resolution? Even if it is so, is it a good idea for the Atlas Web site to display "undefined" where the raw results show that other resolvers worked?

Measurement with msm probe type isn't working

Dear Atlas team. I have a script to launch a new measurement using an old measurement list of probes ids, using type:msm.

I solved it downloading the list of probes using a GET to https://atlas.ripe.net/api/v2/measurements//<OLD_MEASUREMENT_ID>?fields=probes' and then giving the complete probes list to my script. Is there any recent change with the type:msm call? Thanks, Hugo

Feature Request to consider: DNS response IP header

Question about built-in first/second hop latency measurements

Dear RIPE Atlas users, We have planned maintenance on the main RIPE Atlas backend database tomorrow (Tuesday, 16 July) starting at 08:00 UTC, 10:00 Amsterdam local time. We expect complete unavailability of the service for a short while and further intermittent delays during the day. During this time the website (UI and APIs) will not be responding (properly). This also means that requests for new measurements will be denied or delayed. Data from existing measurements will still be collected normally, though access to them will be impacted. Our apologies for the inconvenience. Regards, Robert Kisteleki

Including TCP handshake it takes 23.7ms, 2.8x longer which is expected . RTT can be measured on different layers for the same communication stream. In case of DNS over UDP we just ignores UDP overhead because it doesn't add any packets. With TCP additional packets are added which significantly increase time that end-user have to wait from first packet to get information that he/she needs. IMO RTT should always be measured from 1st packet to packet which has information that you have actual data. If we want to measure raw DNS performance without overhead then it must be explicitly market it measurement description.

Folks, This page at Atlas provides a great visualization on the RTT of DNS queries over TCP/UDP to the Root DNS servers: https://atlas.ripe.net/results/maps/root-server-performance/ We can see that the RTT of TCP queries is at least twice as long than UDP ones (which, according to the page " TCP is expected to be 2-3 times " longer. I cannot replicate these results in my setup, even in large scale from various vantage points: I always get very similar results for either TCP or UDP. Example: UDP: * $ dig example.nl @ns1.dns.nl Query time: 8 msec TCP: * $dig +tcp example.nl @ns1.dns.nl Query time: 9 msec I think there might be something with the definition of RTT. My hypothesis is that the field *rtt* on DNS queries on Atlas[1], for TCP, is, in fact, measuring 2 RTTs: the RTT of the TCP handshake, and the RTT of query/response itself. By definition, however, RTT is "the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgement of that signal to be received."[2]. So if DNS TCP measurements starts measuring from the SYN packet, that', in fact, be two RTTs. Is this the case with Atlas? I know it may sound a bit like nitpicking, but I just want to be sure of what's exactly being measured. thanks a lot, /giovane [1] https://atlas.ripe.net/docs/data_struct/#v4750_dns [2] https://en.wikipedia.org/wiki/Round-trip_delay_time

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
