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.

RIPE Atlas Quarterly Planning Q3 2022
by Robert Kisteleki 30 Jun '22

30 Jun '22

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?

[Message already sent on 6 june but it never appeared in my mailbox.

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
by Lukas Magauer 03 Jun '22

03 Jun '22

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. Regards, Anand Buddhdev RIPE NCC Hi everyone, accoring to this site, a CentOS 7 installation is required for running a Software Anchor: https://atlas.ripe.net/docs/anchor-installation-vm/ But CentOS 7 will be End-of-Lifetime in two years (30.

I searched the atlas mailinglist topics for "software anchor" and "centos 7" but didn't find anything. Greetings, Simon

From: Meikel Kokowski Sent: Tuesday, 24 May 2022 02:48 To: ripe-atlas(a)ripe.net Subject: [atlas] Ongoing problem with DoT measurements Dear RIPE Mailing List, in the context of my final thesis I am conducting research related to DNS (Do53 and DoT) using RIPE Atlas probes. In preparation for the main measurement I issued, to around 4800 probes, DNS queries 1) over TLS [measurement ID: 41196896] and 2) over Do53 (standard) [measurement ID: 41196980] While Do53 works perfectly, DoT seems not to yield any results at all. In the RIPE Atlas forum I found a similar question (https://www.ripe.net/participate/mail/forum/ripe-atlas/PDIwMjIwMzI0MTIzMzE1…). According to that thread, a configuration error on the probes causes the problem. That post is 2 months ago and the problem seems to subsist. Could you provide an update to the current situation to this problem and a possible date for a fix? Thank you! Best, Meikel

Hi, I may be wrong but it looks like there are 3 probes at ASN34659 (Keyyo) and only 1 is up ? Can anyone confirm ? Thanks, Jacques -- GnuPg : 156520BBC8F5B1E3 Because privacy matters. « Quand est-ce qu'on mange ? » AD (c) (tm)

Looking for a hardware probe
by Giuseppe Macario 25 May '22

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. PS: not interested in software probes. -- Giuseppe Macario, PhD https://giuseppemacario.men https://www.giuseppemacario.it

RIPE-Atlas measurements showed "No recent report available"
by Tingting Lu 25 May '22

Hi all, I am using RIPE-Atlas to generate some ping measurements for my testing ip recently. It worked very well until yesterday. Starting from May 23rd, most of my measurements only have results for a few probes. Most probes showed "No recent report available". Does anyone have the same problem or know what's going on there? -- Regards, Tingting Lu

Probe TLS stack
by Christopher Wood 15 May '22

15 May '22

Hi folks, Apologies in advance if the answer to this question is available online somewhere, but I’m wondering if anyone knows what TLS stack is used in Atlas probes, and in particular, what sort of TLS features are configurable by such probes. Best, Chris

Future of Software Anchors
by ripe.net＠toppas.net 15 May '22

Hi everyone, accoring to this site, a CentOS 7 installation is required for running a Software Anchor: https://atlas.ripe.net/docs/anchor-installation-vm/ But CentOS 7 will be End-of-Lifetime in two years (30. Juni 2024). https://wiki.centos.org/About/Product So it does not really make sense, to set up a new Anchor with CentOS 7, i guess. What are the plans, dear RIPE Labs? I searched the atlas mailinglist topics for "software anchor" and "centos 7" but didn't find anything. Greetings, Simon
