Responsive Probe Fluctuations
by Marcel Flores 05 Apr '19

05 Apr '19

Hi All, Noticed a funny little swing in probe responsiveness. It seems to have returned to normal, but was curious if anyone else had seen it. We do one-off measurement where we select all probes, usually the responsiveness rates look something like: 12743 Requested / 10147 Actually Participated (Taken from 18 March) But on 19 March we started seeing rates more like: 12914 Requested / 7852 Actually Participated Which continued until about 28 March, when it returned to about the previous levels: 12916 Requested / 9943 Actually Participated Something funny happen with the dispatching? Did anybody else see? -- *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

Probe not coming online anymore after firmware upgrade
by Annika Wickert 25 Mar '19

25 Mar '19

Hi everyone, I bought a new USB Stick for this probe as the old one was tagged as readonly etc.. https://atlas.ripe.net/probes/23913/ <https://atlas.ripe.net/probes/23913/> In the panel it says: 2019-03-21 14:50:02 UTC Probe firmware upgraded Your probe #23913 <https://atlas.ripe.net/probes/23913/> upgraded its firmware from version 3.3.8 to version 4960 But for some reason it is not coming online at all :(. Any idea what could be the issue? I also see no network traffic at all originating from the probe. Best, Annika

Request RIPE Atlas Credit for Research
by 陆超逸 07 Mar '19

07 Mar '19

Dear all, Greetings! I'm a PhD student at Tsinghua University, China. Recently a large-scale measurement via RIPE Atlas is needed for my research. However, as a new user I don't have any credit to proceed, and unfortunately the time doesn't allow me to earn them by myself. So I'm here to ask for help. Is it possible for anyone generous enough to offer me some RIPE Atlas credits (like, a million)? My account at RIPE NCC is lcy17(a)mails.tsinghua.edu.cn. Many thanks for your help! Sincerely, Chaoyi Lu

Graphing packet loss
by Steve Hill 01 Mar '19

01 Mar '19

I've got some ping measurements set up and am trying to find a good way to visualise outages. The Latencymon tool obviously shows red shaded sections on the graphs for an outage, but they vanish when zoomed out a long way. A graph of average packet loss seems the obvious way of doing it, but it doesn't look like there's any way to get this from the Atlas website, sort of downloading the data and building my own tool to analyse it. Am I missing something obvious? :) -- - Steve

Time difference between results and update of measurement status
by Vasileios Giotsas 25 Feb '19

25 Feb '19

I've seen that the status of a measurement is updated much later than when the measurement results become available. For instance, while the RTTs of a ping measurement are returned the status is still Ongoing for up to 3 minutes. Is there anything (such as sanity checks) that intervenes between the update of the results and and update of the measurement status, which may change the results? Or is it safe to assume that once the results are out the measurement status will eventually change to 'Stopped', just a bit later? Thanks! Vasileios

Issue with RIPE Atlas HTTP measurements
by Philip Homburg 19 Feb '19

19 Feb '19

We recently discovered an issue with RIPE Atlas HTTP measurements. In trying to fix an issue that caused the HTTP body size to be reported incorrectly, we inadvertently introduced a bug that prevents the measurement from working under certain conditions. This bug affects firmware release 4940 and the upcoming releases 4950 and 4960. The combination that fails is a recurring measurement after the first run with an HTTP server that returns the body as chunks. This means that one-off measurements are fine. Unfortunately, HTTP measurements that are part of anchoring measurements are affected. We will work to fix this issue in the first firmware release after 4960, which can be expected in the next couple of months. We apologise for the ongoing issue and will keep you informed as we work to resolve it. Philip

Re: [atlas] "Cannot resolve" tag on IPv6-only network?
by ripe＠brite.cz 14 Feb '19

14 Feb '19

https://atlas.ripe.net/about/faq/#i-have-an-ipv6-only-network-will-the-prob… says I have an IPv6-only network. Will the probe work on it? Yes. All probes can be configured statically with an IPv6 address, default router, DNS resolvers, etc. through the web UI. In addition, version 3 probes can be fully configured through router advertisements (support for RFC 6106 was added in firmware release 4680). There is at the moment no support for DHCPv6 (RFC 3315). Version 1 and 2 probes can obtain addresses and default routers through router advertisements, but cannot obtain DNS resolvers that way. For those probes, the DNS resolvers will have to be configured statically through the web UI. ______________________________________________________________ > Od: "Lorenzo Colitti" <lorenzo(a)google.com> > Komu: "Anand Buddhdev" <anandb(a)ripe.net> > Datum: 14.02.2019 12:47 > Předmět: Re: [atlas] "Cannot resolve" tag on IPv6-only network? > > CC: <ripe-atlas(a)ripe.net> >On Sat, Feb 9, 2019 at 7:47 PM Lorenzo Colitti <lorenzo(a)google.com> wrote: > >> IPv6-only networks are certainly supported, but if the probe isn't aware >>> of any DNS resolver, then it's not going to be able to do any of its own >>> DNS lookups, and that's why it's been tagged with the "cannot resolve" >>> tags. >>> >> >> Hmm.

"Cannot resolve" tag on IPv6-only network?
by Lorenzo Colitti 14 Feb '19

14 Feb '19

My probe v1 is on an IPv6-only network with NAT64 and DNS64. In the web UI I see it's tagged with "cannot resolve A" and "cannot resolve AAAA". Are IPv6-only networks supported? Is this because the network doesn't have a DHCP server? Something else?

shared fate for my two probes
by Jay Borkenhagen 08 Feb '19

08 Feb '19

Hi, My two RIPE Atlas probes have been acting strangely over the past several months. Very frequently I receive automatic notices from the RIPE Atlas system that both of my probes have been "disconnected from the RIPE Atlas infrastructure" essentially simultaneously. Here's the history from 2018: probe 11171 2018-02-23 18:08:57 UTC. probe 11203 2018-02-23 18:10:23 UTC. probe 11171 2018-06-21 04:32:15 UTC. probe 11203 2018-06-21 04:30:59 UTC. probe 11171 2018-06-24 05:36:57 UTC. probe 11203 2018-06-24 05:37:04 UTC. probe 11171 2018-07-31 20:25:27 UTC. probe 11203 2018-07-31 20:25:32 UTC. probe 11171 2018-08-18 04:48:20 UTC. probe 11171 2018-09-15 02:31:26 UTC. probe 11203 2018-09-15 02:31:28 UTC. probe 11171 2018-10-15 23:03:50 UTC. probe 11203 2018-10-15 23:04:06 UTC. probe 11171 2018-11-16 14:42:28 UTC. probe 11203 2018-11-16 14:42:33 UTC. (Those last three events are eerily periodic.) Each time when I am finally able to visit inspect the probes (both are reported as "Firmware Version 4940 (1100)"), their LEDs are in the same state: --------------- Looking at the units with the on/off LED to the left: (1) the left-most (on/off) LEDs are on steadily. (2) the next LED is off. the next two LEDs are flashing at different frequencies: (3) the next flashes on approx. 48 times per minute (4) the next flashes on approx. 110 times per minute (5) the centers of the wide "WPS/RESET" LEDs are on steadily. --------------- Once these probes fail they remain offline until I try turning it off and on again. The probes are powered similarly: the RIPE-provided USB cable is plugged into an Apple iPhone USB power adapter, in turn plugged into a standard US 120v / 60 Hz AC receptacle. However, the AC power circuits feeding these receptacles come from two very different sources which should not share fate. Until today both probes have been plugged into ports on the same Cisco switch, but after today's disconnect I moved probe 11203 to a different physical switch that has the same VLANs. None of my other equipment experiences any troubles around the times when these events happen to my RIPE Atlas probes. In the past I have reported these events to atlas(a)ripe.net, but I doubt that the causes cited (e.g. "the problem is with your dns") have been accurate. (I do not blame the atlas(a)ripe.net folks who have responded. Something strange is happening here, and I haven't yet cracked it.) I'm curious whether anyone else sees similar behaviors, or has suggestions for ways to determine what is happening. Thanks! Jay B.

New on RIPE Labs: RIPE Atlas Probes: Delays in Distribution
by Mirjam Kuehne 08 Feb '19

08 Feb '19

Dear colleagues, The good news: RIPE Atlas is growing both in terms of geographical diversity and ASN coverage. What's more, RIPE Atlas is evolving, with a new generation of probe hardware having already passed the test phase and a pilot programme underway to assess the viability of VM anchors. The not so good news: With RIPE Atlas so much in demand, and with our current provider having ceased manufacturing the probe hardware, we've had to dramatically reduce the number of probes we're distributing. Please find more details on RIPE Labs: https://labs.ripe.net/Members/alun_davies/ripe-atlas-probes-delays-in-distr… Kind regards, Mirjam Kühne RIPE NCC

EDNS Client Subnet
by Rami Al-Dalky 31 Jan '19

31 Jan '19

Hello, I was exploring the possibility of using RIPE Atlas probes to do some study on EDNS Client Subnet (ECS), however, the way it is implemented on the probes makes it less interesting. When I tried to create a DNS measurement, I found that the only way to send DNS query with option is to set default_client_subnet to True. However, by setting this option, a DNS query will be sent with 0.0.0.0/0 as client subnet. According to the RFC, a compliant resolver which receives such content SHOULD NOT forward the client IP to the Auth. DNS server (which the same behavior when you set the flag to False). That's make it impossible to study the protocol from Auth. DNS perspective. Is there a reason why ECS is implemented that way? If it for privacy issue, the RFC recommends to sent the client IP with /24 prefix for IPv4 and /56 for IPv6 to preserve the privacy. Thanks in advance! Rami

Bug in DNS client subnet measurement
by Philip Homburg 31 Jan '19

Hi, We got a bug report that using the DNS client subnet option in a measurement results in a form error. It turns out that probe firmware version 4940 will send a malformed DNS query. Code cleanup related to other changes fixes this issue in the upcoming firmware. We expect to release the new firmware in about one month from now. Philip

Probe v1 disconnecting every 2 hours
by Hugh Saunders 30 Jan '19

30 Jan '19

Hey All, My probe v1 (id:65[1]) has started disconnecting roughly every 2 hours. I read a previous post[2] that said this may be related to power, so changed the USB power supply to one that provides 1A (the FAQ says the need 500ma) but no improvement. I don't notice connectivity issues every couple of hours with any other devices on the same switch. Any suggestions welcome :) Thanks.

DNSEC Tag for Probes
by Philippe Mächler 28 Jan '19

28 Jan '19

Hello RIPE Atlas Users I’d like to some measurements about DNSSEC with RIPE Atlas and need a way to check if the probe does DNSSEC validation The docs mention the system-tags e.g resolvs A and resolvs AAAA. Is there something like “system: does DNSSEC validation” if not, is there any other way or is this on the roadmap? 😊 Freundliche Grüsse / best regards Philippe Mächler

Making a bunch of tests/measurements to a single destination is 'tedious'
by Christopher Morrow 24 Jan '19

24 Jan '19

howdy! So, if I have a dns server somewhere and I want to make a bunch of measurements: "how does NYC see my dns?" (pick N probes near NYC) "How does DEN see my dns?" (pick N probes near DEN) "How does LHR see my dns?" (pick N probes near LHR) "how does ...." ...you get the idea... I'm trying to characterize my service from a 'user' perspective by large Metropolis, well within N km of that metropolis anyway :) but across ~70 or so metros, in v4 and v6 and with authoritative and non-authoritative queries with each test running for 4 days so i can see some daily cycles in traffic patterns/etc. The number of measurements is large in total, breaking up by 3-4 metropolis chunks is super tedious :( Can I request an API key (or some other thing) which can make that sort of request happen for all my measurements in one go? The thing I'm probing is very able to handle a few extra thousand queries per second.. and I'd only be hurting myself i get my estimate wrong :) thanks! -chris

(one is documentation prefix the other is ULA I think?) I suppose test requestors should check the ipv6 prefix to see if it's at least plausibly correct until some signal back to the owners can be attempted?

Re: [atlas] IPv6 Doesn't Work
by ripe＠brite.cz 22 Jan '19

22 Jan '19

Hi, you pointed me to the right way. I enabled IPv6 on my Windows Laptop and it show the same symptoms - it receives an IPv6 address but is not able to reach any IPv6 target. My setup looks like this: Atlas Probe > Ubiquiti airRouter > provider's WIFI AP When I connect my laptop stright to the provider's WIFI AP then IPv6 works all fine. When I connect to LAN port of my airRouter, it receives an IPv6 address but is not able to reach any IPv6 target. So the point of failure seems to be my router. It is set to Bridge mode with WIFI as a client, connected to provider's AP. Per the Manual: ---------------------------------------------------------- Bridge In Bridge mode, the AirRouter forwards all network management and data packets from one network interface to the other without any intelligent routing. For simple applications this provides an efficient and fully transparent network solution. WLAN (wireless) and LAN (Ethernet) interfaces belong to the same network segment and share the same IP address space. WLAN and LAN interfaces form the virtual bridge interface while acting as the bridge ports. The bridge has assigned IP settings for management purposes. ---------------------------------------------------------- The Bridge management interface shows following addresses assigned: 10.0.0.29 2A00:1028:8D1C:90DA:DE9F:DBFF:FE5C:632B/64 FE80::DE9F:DBFF:FE5C:632B/64 I would think the Bridge mode should not interfere the traffic in any way. I have read only access to the provider's AP - it is cheap router with IPv4 NAT and IPv6 interfaces. It shows an IPv6 address [starting with 2a00:1028:] on its WAN IPv6, LAN IPv6, IPv6 Default Gateway, IPv6 DNS server, etc. As I said, when I connect laptop stright to the provider's AP, IPv6 works. I'm unable to to setup my airRouter for IPv6 to work. It supports IPv6, but in bridge mode it has no settings available. I tried multiple factory resets, with various settings, and also tried to switch the airRouter to SOHO Router mode, then there is IPv6 Enable checkbox. While it is checked, I tried various settings, such as SLAAC, DHCPv6, etc. No go. Looks the IPv6 support in this router is broken. It's a pity I cannot connect Atlas Probe v3 stright to the provider's WIFI eventhough it has WIFI hardware onboard. There is no way I could connect stright by LAN cable to the provider. It looks for now I have to leave the Probe live with IPv6 broken. Cheers Jiri ______________________________________________________________ > Od: "Stephen D.
