Riple Atlas + openwrt + docker + gns3 + debian
by Gery Escalier 07 Sep '22

07 Sep '22

Hi, I'm doing tests with OpenWrt SNAPSHOT, r20377-ca5c695a45 on docker in a gns3 lab and on debian 11. At the moment it allows me to carry out tests and later it will allow me to work with old routers and other hardware that can run openwrt. root@OpenWrt:~# /etc/init.d/atlasSyntax: /etc/init.d/atlas [command] Available commands: start Start the service stop Stop the service restart Restart the service reload Reload configuration files (or restart if service does not implement reload) enable Enable service autostart disable Disable service autostart enabled Check if service is started on boot Check if service is running status Service status trace Start with syscall trace info Dump procd service info get_key print probe public key (used for probe registration) probeid print probe id log print probe status log create_backup backup ssh key to tar.gz load_backup 'backup.tar.gz' load backup ssh key from tar.gz create_key create probe priv/pub key root@OpenWrt:~# /etc/init.d/atlas info{ "atlas": { "instances": { "instance1": { "running": true, "pid": 4707, "command": [ "/usr/libexec/atlas-probe-scripts/bin/ATLAS" ], "term_timeout": 5 I have done the configuration that the software probe account requires, I have done the configuration of the riple atlas package to generate the ssh keys and connect with my riple atlas account. I have had the probe 100% operational for several hours and generated credits, the problem I currently have is that when I turn off and start gns3 I have to install the Ripe Atlas packages from scratch in openwrt, configure it and generate the ssh keys again, update the keys in my Ripe Atlas account. At the moment I am using this option for testing, but it would be interesting if openwrt saves the data persistently, I am looking for information on what the problem may be, I am commenting on it in case someone who has used openwrt and something similar has come up. I will be updating news. Greetings. Gery

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

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

Probe on sailboat with Starlink
by Michael Markstaller 02 Sep '22

02 Sep '22

Hi, just a question: any interest to have a probe on a sailboat with Starlink (not officially supported) Just got my probe Probe #27837 fixed again at home (usb-stick RO/dead) and now I wonder if I leave it at home or take it with me over Adriatic/Atlantic. And if yes, some API-way to update location would be nice as we're moving:-) best regards Michael Markstaller Softwareentwicklung & IT-Dienstleistungen Am Birkengarten 19b 82024 Taufkirchen Tel: +49-89-21553825, Mobile: +49-179-2080789 USt-ID: DE293191950

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.

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

Connectivity Issue - Software Probe ID 1002750
by Thomas Kessler 02 Jul '22

02 Jul '22

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

Overuse of software probes
by Ponikierski, Grzegorz 30 Jun '22

30 Jun '22

Hello all! Software probes is great improvement for Atlas environment and it made deployments so much easier and more scalable. One of my probes is also software probe on Raspberry Pi. However, me and my team noticed that sometimes software probes are overused and make measurements more cumbersome to interpret. For example we found that there 4 software probes in AWS Johannesburg [1] and 15 software probes in Hostinger Sao Paulo [2]. That's total overkill. These 15 probes in Hostinger Sao Paulo is 21% of all connected probes in Brazil. All of them delivers practically the same results so without additional data filtering (which is not easy) they can dramatically skew final results for Brazil. With this I would like to open discussion how to handle this situation. Please share your thoughts about these questions: * How can we standardize data filtering for such case? * How to proactively and automatically detect overuse of probes? * How can we encourage software probes hosts to avoid deployments in data centers which are already covered by Atlas? * How to give incentives to deploy probes in data centers without existing probes?

Probe on OpenWRT does not load telnetd
by Ernst J. Oud 30 Jun '22

30 Jun '22

Just a tip for OpenWRT users. I noticed that during most reboots my new SW probe on OpenWRT 21.02 does not load the telnetd daemon. No idea why but I saw that its priority in init.d is rather high (S30), i.e. it loads rather early. Perhaps that is the problem but instead I test for telnetd running in the ATLAS loop and load the daemon if not. Regards, Ernst J. Oud Met vriendelijke groet, Ernst J.

Dear colleagues, The quarterly plans for RIPE Atlas can now be found at: https://www.ripe.net/support/documentation/quarterly-planning/ripe-atlas In this quarter, we will continue with the development of the v5 RIPE Atlas hardware probes among other items as well as start working on two proposals to implement general availability of HTTP measurements and restricting the ability to schedule "non-public measurements". The goal of our quarterly planning is to communicate the work we’re doing for the coming months, get your input and start a discussion on other developments we should work on. If you have any input on our plans or want to let us know what you would like to see us work on, please let us know. Kind regards, Robert Kisteleki Research and Development Manager RIPE NCC

Assigned AS vs. Advertising AS
by ripe.net＠toppas.net 29 Jun '22

29 Jun '22

Hi Everyone, worldwide, there are a lot of IP prefixes which are not advertised by the owner AS. Instead, another AS announces the prefix on behalf of the owner. For example: Amazon allows you to announce your prefix via AWS. For other people, this can lead to misassumptions (assuming a wrong IP owner). https://aws.amazon.com/about-aws/whats-new/2018/10/announcing-the-general-a… Another example would be a multi ASN company which announces all prefixes from a single ASN via BGP, even though the prefixes are assigned to various AS numbers. Since the RIRs do have the information, to which AS a specific prefix is assigned to, i would like to ask for more transparency. I would appreciate, if we could see more details here, and even more important: filter for such criterias when creating a new measurement. Anyone else here, who thinks that's useful? BR, Simon

DNS issues
by Phillip Remaker 29 Jun '22

29 Jun '22

I have installed a probe (/14226) at a rural fixed wireless location which has had intermittent issues from the carrier (AT&T). I got the tag about a DNS issue (Doesn't Resolve A, DNS Problem Suspected). Is it possible to get logs for when the DNS issue happened so I can take it up with the carrier? Also, when does the DNS problem tage clear? Thanks!

Meaning behind "TU_BAD_ADDR" error
by Meikel Kokowski 22 Jun '22

22 Jun '22

Good evening, While parsing data from some of my measurements (using ripe.atlas.sagan) I stumbled over the “TU_BAD_ADDR” error. The error message is only “true” which makes it difficult to understand its origin. Furthermore, as opposed to other errors, such as “timeout”, no error is indicated by the is_error method of the DnsResult object. Instead I can only find this in the raw_data (in the dns respone object). In my measurements I send the same DNS query (using probe’s IPv6-address) to public resolver and the probes local resolver over UDP and TCP respectively. The TU_BAD_ADDR error occurred solely on measurements to the probes local resolver over TCP. Respective measurements using the same probes over UDP do not report this error. Another observation is that the source address of the response is not set in the majority of the cases (but that is not always the case). An example measurement is #41853554 (the counter-measurement over UDP #41853806). Does anyone know more about this? Best regards, Meikel

Hi, Thanks for the reply. But it appears to be a common problem for Linux containers in Docker Desktop for Windows. All traceroute commands only show asterisks. As explained here: https://github.com/moby/vpnkit/pull/302 (vpnkit is used by Docker in Windows). So I will have to install the probe in a native Linux environment instead. Which raises another question: if I get the probe running in native Linux, can I transfer my current probe ID to this new installation? Or do I have to apply for a new probe (and disconnect the other)? Regards, Ernst > On 20 Jun 2022, at 12:00, ripe-atlas-request(a)ripe.net wrote: > > Re: No data for ping to second hop?

Discrepancy in documentation?

[Message already sent on 6 june but it never appeared in my mailbox. Is there some email problem at RIPE?] In the documentation <https://beta-docs.atlas.ripe.net/apis/metadata-reference/>, various HTTP methods are used (for instance DELETE to delete a measurement), which is nice, but the examples ("Try it") always show the method GET.

How to get DNS return codes and TTLs
by Dallan Adamson 09 Jun '22

09 Jun '22

I'm doing research that requires me to use DNS recursive resolvers around the world. At a minimum from these recursive resolvers I need to know what return code the probe received from the recursive resolver as well as the TTL of the record from the same request. I haven't found a way to get both of these when doing DNS measurements with Ripe Atlas probes, is there a way to do this?

Future of Software Anchors

Hi everybody! I have been running a Software probe on CentOS 8 since mid 2020. (and since switched it to Rocky Linux 8) It’s unsupported, but also didn’t really make any problems, just worked fine with the yum repo distributed package! Great that there are already plans to support newer versions as well! And has there something changed in the distribution of the package? Because the latest changes of version 5070 don’t look like they appeared in the GitHub repo?

For now, we are still deploying Atlas anchors with CentOS 7. However, in the latter half of this year, we plan to work on adapting our configuration systems to a newer Linux distribution. After that, we will upgrade all the Atlas anchors (hardware and virtual) to the newer distribution.

Hello everyone, I would like to host a new Atlas probe (for AS203591) but I understand that RIPE is not shipping probes anymore; I applied online but nobody responded. Therefore, feel free write me an email if you have one for sale, in which case I am willing to pay via PayPal. I will also ask RIPE for a new probe ID, so the history attached to your old probe will be reset.

My probe's not doin' IPv6
by Edward Lewis 23 Apr '22

23 Apr '22

General question… My probe was doing IPv6 until 15 July 2021 but not it is not. Is there any way to discover why it is no longer IPv6’ing? I did change my ISP connection equipment about that time, so something did change on my end. But IPv6 works for other devices. When I go to www.ripe.net <http://www.ripe.net/> it tells me I came from an IPv6 address. The device has been pretty steady - 99.71% the last week, 99.91% for the last month (30days). It was off-line 29 minutes earlier today (the notice made me think to look), but never off line more than 10 minutes since mid-July. There’s one stretch of 34d+ of continuous uptime. Run-of-the-mill home connection via a cableTV company. Is there anyway to ask a probe why it doesn’t have an IPv6 address (via DHCP)? Ed

Hi, I have a problem reusing probes from previous measurements. I’m launching experiments in pairs from the web interface. I would like to retrieve the probes selected randomly in one experiment for another measurement that takes place at the same time. My problem is that it takes time to show the measurement I created in the list of "my measurements". Even when all measurements are shown in the list of all "my measurements", the creation interface does not find all these measurement ids. So I cannot retrieve the probes I need. Is there an access problem to the measurement DB or am I doing something wrong? Cristel

Problem with DoT measurements?
by Stephane Bortzmeyer 24 Mar '22

24 Mar '22

DoT measurements seem partially broken, only 10 % of the probes do report. (See for instance #39675721.)

Facebook in Russia and a diagnostic problem
by Stephane Bortzmeyer 14 Mar '22

14 Mar '22

Around half of the RIPE Atlas probes in Russia cannot complete a TLS session with facebook.com <https://atlas.ripe.net/measurements/39387725/>. (All the remaining tests have been done with the same set of probes, 'type': 'msm', 'value': '39387725'.) They have no problem with YouTube <https://atlas.ripe.net/measurements/39387839>. I also did TLS tests with IP addresses instead of names, same result <https://atlas.ripe.net/measurements/39387985> <https://atlas.ripe.net/measurements/39388031>. There is no lying DNS resolver <https://atlas.ripe.net/measurements/39387902>. But traceroute show no connectivity problem either, we can go to the Facebook AS from Russia <https://atlas.ripe.net/measurements/39388122> <https://atlas.ripe.net/measurements/39388176>. So, I'm a bit lost: what do we observe? It does not look like censorship but not like a connectivy issue (because of depeering by Cogent and Lumen) either.

broken atlas streams
by Teun Vink 04 Mar '22

04 Mar '22

Hi, We’re seeing some issues with RIPE Atlas streams using the ripe.atlas.cousteau websocket library. Sockets seem to connect properly, but no data is received. tcpdumps show very little traffic. One of the already running receiver application (monitoring the exact same set of measurements) is receiving data, but any newly started daemon fails to receive data. Is there an issue on the RIPE Atlas infrastructure? Thanks, -- Teun Vink BIT | teun(a)bit.nl | +31 318 648 688 KvK: 09090351 | GPG: 0xFC8B25D6 | RIPE: TEUN-RIPE

My Atlas > Credits reporting wrong total daily income?
by Jaewon Kim 19 Feb '22

19 Feb '22

Hello, List! First of all, this is my first time posting to any kind of mailing list, so apologies if I did something wrong. Please let me know if so. I'm having this weird issue where 'My Atlas' page showing wrong info for "total daily income" (around 2x of what I'm actually getting). As you can see above, Atlas is reporting that this specific probe is earning 64K a day, and the total income is around 615K. However, if I see the actual credits page, None of my probes are actually earning that much. Plus, the hourly income is 13.7K, which sums up to around 330K/day. This isn't a big issue to be honest, but just got curious (and confused) with it. If anyone knows a fix for it, or why this is happening, it would be great :) Thank you! Best regards, Jaewon.

monthly information about probe availability
by MAYER Hans 14 Feb '22

14 Feb '22

Dear All, We get this monthly e-mail about probe availability. This is great. But there are some questions. What exactly is getting measured? Is this a connection to some external site? Which could mean that there are other factors that could influence the measure (i.e. that external site is down, etc.) Kind regards Hans —
