Credit sponsorship
by Finn Holler 07 Nov '22

07 Nov '22

Hello, I am looking for probe operators, with a credit surplus, who would want to transfer some credits to my RIPE Atlas account (email: finn.holler(a)student.uni-tuebingen.de). These credits are required for me to interact with the measurement API, which I want to explore and ideally use, to implement a service indicating the connectivity status of various internet services to tenants of local student housing. The plan is to register some probes, so this credit sponsorship is only necessary for initial trials. Best, -Finn

Breaking API change?
by Ray Bellis 26 Oct '22

26 Oct '22

ISC's Root System Atlas visualiser used to use this API call to access the built-in root system measurements: <${apiUrl}/measurements/${m}/latest/?fields=responses.0.response_time,responses.0.abuf.answers.0.data.0&freshness=1800> where ${m} is the measurement number. It used to return this object: { probe_id1: [ [ latency, site1 ], ... ] probe_id2: [ [ latency, site1 ], ... ] ... } It now returns this array instead: [ [probe_id1, latency, site], ... [probe_id1, latency, site], [probe_id2, latency, site], ... ] and I had to explicitly request the probe_id field in order to get it. Was this change intentional, a regression, or did I not use the API right in the first place? cheers, Ray

V4 probe looses connection
by Szabolcs Sipos 22 Oct '22

22 Oct '22

Hi, I have a probe (#53985, V4, fw: 5070) that goes offline after 1-2 days of uptime and does not recover unless rebooted. The probe responds to ping (even from a different subnet). Packet capture reveals that it renews its DHCP lease normally, but does not initiate any higher level connection. I will try to keep the probe online for a few days so that you can run some tests if you wish. Regards, Szabolcs

Hi, In the past the probes that had shared management were shown below the owned probes. This is not the case anymore. Is this intentional? Can it be restored? Thanks, Dave

ATLAS page broken because of Cloudflare
by Max Grobecker 16 Oct '22

16 Oct '22

Hi, on my network, the RIPE ATLAS page is not working because mandatory resources (i.e. Javascript) can't be loaded, because appearently ripe.net is now running behind Cloudflare and is blocking requests to static resources - see attached network console screenshot of my browser. There should be made a rule to exclude static assets or trusted origins from this type of filtering. This is maybe also affecting other pages, which include resources directly from www.ripe.net. I'm accessing this over a mobile network via IPv6 (Telefonica Germany), so it's not a "other bad person behind same CGNAT" problem but a seemingly static rule to always challenge the client. Greetings, Max

Tagging probes which are using the ISP's DNS server?
by Max Grobecker 11 Oct '22

11 Oct '22

Hi, a few days ago I wanted to debug a name resolution problem of one of our domains. For this reason, I wanted to test if probes inside a specific ASN are having difficulties to resolve a specific name (because only customers of this ISP were complaining). This lead to very mixed results, mostly because some of the selected probes did queries to a public DNS service like Google, Quad9 and so on. The problem existed only with the provider's DNS servers for some reason. It did take some time to make a script which tried to filter out these probes, so I wondered if anyone else had the same use-case and problem. Is there a way to automatically tag probes, which are (seemingly) using the ISP's own DNS servers, or, at least, not a well-known public service? This could be done maybe by querying a special DNS name which returns the IP address from where the query was received (like "whoami.akamai.net"). By comparing the ASN of the probe and the ASN of the IP address returned by the DNS query, one could determine, if the ISP's servers are used. This would also be true for people running their own recursor, but this could be filtered as well very easy. If an ISP is using multiple ASN, this could be a problem. Maybe there's an easy solution for this as well. Probes which pass this test, could then be tagged with "DNS-using-ISP-server" or something like that and explicitly be selected for specific DNS resolution tests. Greetings, Max

API error
by Ernst J. Oud 07 Oct '22

07 Oct '22

Hi, Since a short while (1 or 2 days) I get an authorization error when downloading the data from the built-in first and second hop to ping.ripe.net. Thus: https://atlas.ripe.net/api/v2/measurements/1/results/?probe_ids=1004467&sta… Gives: {"error":{"detail":"Authentication credentials were not provided.","status":403,"title":"Forbidden","code":104}} If I logon with my credentials via “My Atlas”, I get: {"error":{"detail":"You do not have permission to perform this action.","status":403,"title":"Forbidden","code":104}} All other tests let me download the data fine, logged in or not. Same happens to download first and second hop data of other public probes. Any clues? Regards, Ernst J. Oud

Re: [atlas] API error
by Ernst J. Oud 05 Oct '22

05 Oct '22

L.S. If for some reason this api error bug takes longer to resolve and the data is important for you, a work around is to download this data from ripestat. Click on the link on your builtins page for the larger graph and click the download button top right. Use this download link to download future data by changing the start and end time in the URL. Reason I use the data from the first hop latency is that my CentOS probe in a VMware Player VM on Windows 10 (bridged) takes 2-3 ms. for the first hop. To get more realistic data for other measurements I subtract this first hop latency data from data of other measurements. Wrote some Freebasic code for this and created my own graphs using the good, old, trusted application ploticus. From the host Windows 10 PC first hop is max 0.5 ms. so the VMware software bridge is not very efficient to get a connection going. If the CentOS VM is kept busy, the first hop is much faster. It is as if Windows and/or VMware suspends/sleeps the thread of the bridge when not active. I searched but did not find any more reports let alone solutions for this weird first hop phenomenon in VMware/Windows environments. Regards, Ernst J. Oud

Change in Probe Archive API
by Johan ter Beest 26 Sep '22

26 Sep '22

Dear probe hosts, Since 2013 we are creating a daily snapshot of the probe API which is available at https://atlas.ripe.net/api/v2/probes/archive Until today, this snapshot included some probes which had never connected. Starting with the snapshot of today (26 / 09/ 2022) we will exclude all never connected probes from the archive as they do not provide any useful information. Previous snapshots will not be altered. In addition to this change, every known probe will now have a probestatus page at https://atlas.ripe.net/probes/<probe ID>/ where previously some of these probes would generate a 404. Let us know if you have any question or comment about this change. Kind regards, Johan ter Beest RIPE Atlas Team

Group in Spanish Riple Atlas?
by Gery Escalier 06 Sep '22

Hello everyone, I have the doubt if there is any group in Spanish where I can participate, I have been documenting myself about Riple Atlas and I have been able to activate a software probe using openwrt, gns3 and Debian. It is always more interesting to be able to carry out tests and others participating with the community. I have seen some videos of the deployathons in which Michela G. and Agustin F. participated, that is why I was encouraged to configure the probe and understood a little better about the Riple Atlas project. I will also participate here and I will be sending emails with my queries. Thank you very much, best regards! Gery

Re: [atlas] My experiences with a SW probe…
by Michel Stam 07 Jul '22

07 Jul '22

Hey Ernst, Thanks for your email. Regarding the busybox implementation, there’s history here. As I understand it, the first probes were implemented on a system without a memory management unit. This created the problem that starting and restarting processes caused memory fragmentation. That lead to the system running out of memory, which is why an approach was chosen with a multi-call binary: Only one program loaded into memory, and busybox already was implemented and available on the system. Of course, since the version 3 probes (the TPLINK), there is no need anymore. There is a memory management unit taking care of this. However, the code was retained because it was already implemented. Later on, the decision was made to offer an installable software probe package for regular Linux systems, which is in essence the same code running on the hardware probes, which brings us to today. Today you find busybox even on regular Linux systems, but then typically in the initrd environment, prior to the system booting from the root filesystem. We’re currently refactoring parts of the probes to make things easier to maintain. This may mean, without guaranteeing it, that this can change in the future. Why ATLAS starts properly using /etc/init.d and not on boot, I cannot say. It can be as simple as the networking not being available or a race condition. I would suggest to touch base with the author of this code and ask? The debate whether a Windows version would be beneficial is something that we should have with a wider audience, and should cover such topics as 24/7 availability, usability and convenience for the user. I merely want to point out that the engineering effort may be significant. If other people would like to weigh in on this matter, that would be welcome. Will keep you posted.

Only when VMware was installed also on that PC in bridge mode, those measurements went haywire.

When I had a look at the SW probe after installation I indeed wondered what the heck was going on with a busybox binary, which in embedded Linux environments and in small Linux distributions such as Alpine, has its place.

Also I noticed that the traceroute results of the SW probe are around 1 ms. higher in the first hop, due to the probe running in a virtual machine. Both issues are not a big deal. What I meant more is that the amount of people willing to install the probe, if a Windows service would be available, would be potentially much, much larger.

My experiences with a SW probe…
by Ernst J. Oud 05 Jul '22

05 Jul '22

Don’t know whether this is the place to share experiences but … I installed a SW probe in Docker for Windows (the Alpine version). Turns out traceroute doesn’t work in that setup. So I installed VMware player on that PC (the latest version can coexist with Hyper-V which Docker requires) and CentOS and the binary of the probe. Of which the instructions on the Ripe Atlas site doesn’t work in the last step (yum complains no package atlasswprobe found in the repo). Manual download and install did work however. Hurrah. Turns out traceroute in that setup only works with VMware in bridged network mode. Fine. But… all my bandwidth tests on that same box suddenly showed strange impacts… so either a working probe and accept incorrect bandwidth tests (using Ookla SpeedTest) or find another solution. Apparently the bridge in VMware and Windows on the same physical Ethernet port influence each other. Tried the probe on OpenWRT on a small router. Works fine but I don’t want to dedicate this router to just probe work. Also the ATLAS service from init.d refuses to run the telnetd daemon at startup. Weird. So installed VMware on a separate Windows 10 headless box (Minix Z83) that I had spare with CentOS and the binary. Runs fine. Finally. Will kill the other two probes once I am convinced it now finally works. Thanks Ripe for this excellent tool! A Windows version would help however :-) Regards, Ernst

Hi there, a software probe of mine - ID 1002750 - has stop working about 30 days ago and I seem not to be able to get it to connect again. tcpdump shows plenty of communication between the probe and reg03 / reg04.atlas.ripe.net. As well, the probe sending SOS DNS queries but neither seem to have any effect. RIPE Atlas Console shows the probe as being descended and the SOS DNS queries are not reported there either. I've check the probes registered public key and there should be no issue. Any ideas? Best regards Thomas
