Software Probe version 5110 released
by Trix Taiclet 02 Apr '25

02 Apr '25

Dear colleagues, We have released a new version of the RIPE Atlas Software Probe, version 5110. This 5110 release contains the following changes: * Added support for Raspberry Pi OS 12 (added Debian 12 arm64 package) * Rewrote GitHub README and BUILD instructions * Display Probe registration instructions during installation for RHEL and Debian * Generate Probe keys after installation without requiring service startup * Using the signing key introduced in 5100 to sign RHEL packages. The current RHEL key is deprecated as of this release. * Fixed compilation error by adding a missing include to telnetd.c (authored by César de Tassis Filho <ctassisf(a)gmail.com>) * Hardened the security of the RIPE Atlas service unit (reported by Marek Küthe <m.k(a)mk16.de>) * Added missing requirement for procps-ng on RHEL9 to RHEL probe package specfile (authored by Robert Scheck <robert-scheck(a)users.noreply.github.com>) * Document runtime options for custom TCP ports (authored by AtlasMUC <AtlasMUC(a)mail.de>) * Fixed typo in GitHub org url for RHEL ripe-atlas-anchor specfile (authored by Pouria Mousavizadeh Tehrani <info(a)spmzt.net>) * Fixed typo in GitHub org url for RHEL ripe-atlas-probe specfile (authored by eeple <m.renusson(a)gmail.com>) This release does not contain any functional changes to the measurement code. You can find more information and instructions on the GitHub repository: https://github.com/RIPE-NCC/ripe-atlas-software-probe/ You might have seen this release before our announcement; we faced an issue with the arm64 repo package, which caused us to delay that specific package and our announcement. Please let us know if you find any issues with this release. Regards, Trix Taiclet & Marios Mavropoulos RIPE NCC

Missing data in connection and uptime history for probe
by Anton Bobov 21 Mar '25

21 Mar '25

Hello! I am experiencing an issue with incorrect uptime and connection history for my probe (ID: 1006959 https://atlas.ripe.net/probes/1006959/network) I am currently running a software probe on Rocky Linux 8.10, with the probe version 5100. There was a power outage between 2025-03-14 04:25 and 2025-03-14 05:25 (UTC), which seems to have affected the data. I downloaded the connection history for the specified period, and it shows the following entries: seq timestamp (UTC) event stored_timestamp (UTC) ---------------------------------------------------------------------- 1 2025-02-08 23:13:51 disconnect 2025-02-08 23:13:51 2 2025-02-08 23:17:18 connect 2025-02-08 23:17:18 3 2025-03-14 04:25:35 disconnect 2025-03-14 04:25:36 4 2025-03-14 05:25:06 connect 2025-03-14 05:25:06 5 2025-03-14 06:49:19 disconnect 2025-03-14 06:49:19 6 2025-03-14 06:52:46 connect 2025-03-14 06:52:47 7 2025-03-15 22:36:49 disconnect 2025-03-15 22:36:50 8 2025-03-15 22:39:17 connect 2025-03-15 22:39:17 However, entries [2] to [7] are missing from the connection history, and only [1] (last disconnect) and [8] (last connect) are displayed. Additionally, this period is also missing from the uptime history. Could this be a bug, or is there another explanation for this issue? -- Cheers, Anton

Unable to remove probe's Description
by ripe＠brite.cz 20 Mar '25

20 Mar '25

Hi team, I wanted to remove the Description, before I make new one. When click Edit button, delete the description and click Save, I get "Failed to update probe info". Only if I enter any valid character then it saves fine. I would suggest to allow empty string to be saved as well, since sometimes you just want to remove the description instead of writing a new one. Cheers from Czechia Jiri

purpose of *untagged* status
by ripe.net＠toppas.net 06 Mar '25

06 Mar '25

Hi everyone, can anyone explain to me the reason of system tags not being set (for long time)? There are system tags for every case, but there's also the case, that no tag is being set. For example: ipv6-works check (three possible cases): 1. tagged: system-ipv6-works 2. tagged: system-ipv6-doesnt-work 3. untagged (none of the above tags is set) I don't see the purpose of the untagged status. Either IPv6 / IPv4 works, or not. What is the completely untagged status supposed to tell me? The same applies to DNS checks. There's a tag for every case, plus the "no-tag status": DNS resolving check: 1. tagged: system-resolves-a-correctly 2. tagged: system-resolves-a-incorrectly 3. tagged: system-doesnt-resolve-a 4. untagged (none of the above tags is set) I would like to know the condition, how the controllers (?) decide this. Or in other terms: if a system tag is removed (untagged) shouldn't this implicate, that the opposite system tag has to be applied immediately? This is not a matter of a short time period, completely untagged probes do exist for long time periods. Thanks & best regards, Simon

Request for Additional RIPE Atlas Credits for Large-Scale Internet Measurements
by Semebia Wurah 04 Mar '25

04 Mar '25

Dear RIPE Atlas Community, I hope this email finds you well. My name is Semebia Wurah, and I am a Research Associate at Carnegie Mellon University Africa, working under the supervision of Prof. Theophilus Benson. We are conducting large-scale traceroute measurements using RIPE Atlas to analyze the Internet ecosystem in Africa, with a particular focus on AS peering growth and IXP utilization. This research aims to quantify interconnection trends, detect inefficiencies in routing, and assess the impact of IXPs on regional traffic exchange. Given the scale of our study, we require a substantial number of credits (approximately 500,000,000) to sustain our measurements over an extended period of at least 4 months. These credits will allow us to: - Capture peak and off-peak Internet behavior by running measurements at different times of the day. - Measure interconnectivity across African ASes and IXPs to analyze how traffic is exchanged regionally. - Ensure statistically meaningful results by collecting data over multiple weeks. We truly appreciate any additional credits the community can share, as this will significantly enhance the depth and accuracy of our findings. We are happy to share insights from our research with the RIPE community. Thank you in advance for your time and support. Please feel free to reach out if you have any questions or require further details about our study.

Hi, I'd like to dig a little deeper into some of the results we've seen last year [1] during our PQC DNSSEC measurements [2]. Questions are around the resolver software used etc. Is there a way to directly contact the operator a probe? Or do I have to resort to abuse email addresses from IP whois and the like?

It’s October 2024. Is this plan still valid? I admit that I have a bunch of tools which use URL form which I would have to update to use "Authorization" header. Regards, Grzegorz From: Robert Kisteleki <robert(a)ripe.net> Organisation: RIPE NCC Date: Tuesday, 19 September 2023 at 12:11 To: "ripe-atlas(a)ripe.net" <ripe-atlas(a)ripe.net> Subject: [atlas] Changes to RIPE Atlas API keys Dear RIPE Atlas users, We'd like to update you on some upcoming changes regarding API keys in RIPE Atlas. TL;DR nothing changes regarding how you can use your API keys in the short term - as long as you're actually using them. However, we'll change how unused or forgotten keys are handled as well as remove the less secure in-URL use of them. At the moment RIPE Atlas users can query their existing API keys via the UI and API, including the possibility to retrieve old keys. In order to improve the security of how we handle these, we'll introduce the following changes in October 2023: * The listing (retrieval) of keys will only reveal parts of the keys (enough to identify them) in the API as well as in the UI. * We'll add the ability to "regenerate" an API key, which will replace the secret UUID of the key while keeping exactly the same permissions. * Unused API keys will automatically be frozen after 1 year of not being used. Active keys (i.e. the ones that have been used at least once) will not be frozen. You still have the ability to save your keys until these changes are done and, as written above, you will be able to regenerate them later. We'll notify this list when the changes are about to be done. In addition, in order to further increase the security of our system, in the long run we'll make changes about how these API keys are communicated to the API: * At the moment the API accepts these either in HTTP headers ("Authorization" header) or in the URL (?key=xyz), although the Authorization header version has been documented as the preferred version for some time. * We'll deprecate and remove the ability to use the URL form in about a year (around October 2024). * We plan to send further reminders about this change over time, as well as reaching out to heavy users of the to-be-removed format.

upgrading 5080 swprobe to 5100 on Debian loses config?
by Alexander Bochmann 25 Feb '25

25 Feb '25

Hi - I tried upgrading a software probe that runs on Debian from version 5080 to the 5100 binaries provided by the project, and while the old atlasswprobe package is being removed, it seems there is no attempt to migrate the existing probe key or other configuration? What's the recommended path here, back up the key and copy it into the new configuration directory, or just start a new probe from scratch? Alex.

Porting RIPE Atlas to Microcontrollers
by Urban Suhadolnik 18 Feb '25

18 Feb '25

Hi, I would like to port RIPE Atlas probes to ESP32 as part of my Master's project at TU Graz. Usage of microcontrollers could be an interesting approach to increase the physical availability of probes and to decrease the cost and energy usage. Would it be possible to get some support in this endeavour from the Atlas dev team? I would need some help with the communication with Atlas servers. Best, Urban Suhadolnik

Why measurements using api are apt to fail while those using web interface can usually succeed?
by 孙乐童 02 Feb '25

02 Feb '25

Dear all, I have been attempting to use Atlas to launch traceroute measurements recently. Initially, I used ripe.atlas.cousteau to run the measurements in batches, keeping the total number under 10,000 to avoid exceeding the measurement limit. However, only 10% of the measurements returned successful results, while the other 90% showed the status "scheduling denied." Next, I tried launching only 12 measurements in batch, where each measurement contained one traceroute from a specific probe to a designated IPv4 destination. Out of these, 4 succeeded and the other 8 showed the status "specified". Following that, I launched the 12 measurements one by one with 2-second intervals, resulting in a success rate of 6 out of 12. However, when I increased the interval to 3 seconds, the success rate dropped to 4 out of 12. Interestingly, when I created the same measurements for the designated probes and destinations through the web interface, all of them were successful. Below is the Python code I used to launch the measurements: fromripe.atlas.cousteauimport ( Traceroute, AtlasSource, AtlasRequest, AtlasCreateRequest, AtlasResultsRequest, AtlasLatestRequest, ProbeRequest ) traceroute=Traceroute(af=4, target=dstip, description="traceroute subpref ip {} from {}{}".format(dstip, probe_type, probe_value), protocol='ICMP') if probe_type =='asn': probe_value =int(probe_value) source = AtlasSource(type=probe_type, value=probe_value, requested=1, tags={"include": ["system-ipv4-capable"]}) _key = ATLAS_API_KEY_2 for _ inrange(2): atlas_request = AtlasCreateRequest( start_time=datetime.utcnow() + timedelta(random.randint(0, 1)), key=_key, measurements=[traceroute], sources=[source], is_oneoff=True ) (is_success, response) = atlas_request.create() if is_success: print('create_task', dstip, is_success, response) msm_id = response['measurements'][0] return Could you kindly let me know if there might be an issue with my approach or provide any advice on how to improve this process? I would greatly appreciate any guidance. Thank you very much! Best regards, Sun Letong

Ripe Atlas Measurement Results and API Usage
by Huseyn Gambarov 30 Jan '25

30 Jan '25

Hello. I was implementing a mechanism to read the measurement results from the Ripe Atlas for many asynchronous measurements. In this process, I have faced multiple questions regarding the internal mechanisms of Ripe Atlas, and I would be thankful if you could help me clarify them. First, in the Ripe Atlas, I sometimes get “-1” in the result indicating 100% packet loss and sometimes very long RTTs. Can you tell me please what is the condition when Ripe gives up on a target and marks it as "-1”? Second, I have implemented asynchronous reading using web sockets and faced a rate limit on several concurrent web socket connections. The error message said: 'There are too many connections from this IP address. Try making multiple subscriptions on the same connection.’ Can you tell me please, if there is a limit on the number of subscriptions on the same connection? To solve the issue in the second question, I implemented a polling mechanism that periodically checks if the measurement is finished. In order to not overload the API, I attempted to retrieve multiple measurement results in a single call using the following API endpoint: GET /api/v2/measurements/{pk}/latest/ The documentation of that API endpoint states: "Get the most recent results from one or more measurements”. However, I need help understanding how to specify multiple measurement IDs in this endpoint, because all options I tried failed with HTTP status code 405 (Method Not Allowed). Could you please show me the correct way of using this API endpoint? Thank you! With regards, Huseyn Gambarov
