Plan to Implement RIPE Atlas WiFi Measurements
by Robert Kisteleki 09 Oct '17

09 Oct '17

Dear colleagues, We wanted to update the community and let you know that we plan to start work on the proposed experiment with WiFi measurements in mid-2016. As we communicated in a recent RIPE Labs article, we will work with GÉANT as a test partner to learn more about the operational effects of introducing WiFi measurements to the RIPE Atlas system, in addition to the benefits we believe this could provide for the entire RIPE Atlas community. Please see the article for more details if you are interested: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-wifi-measure… We will continue to update you once we’ve begun work on this plan, and we welcome your comments in the meantime. Regards, Robert Kisteleki RIPE NCC

Probe marked as offline, but it's online...
by Christian Schrötter 10 Nov '16

10 Nov '16

Hello Atlas users! I've connected my probe to a new network environment, to test everything before the big migration starts. It came up again immediately and displayed it's new network details at the WebUI. For the first time there was an IPv6-ULA prefix visible. The router (OpenWrt 15.05) supports full IPv6 via tunnel, but it's not advertised to the probe's VLAN and blocked by firewall rules. Everything seems to work, good! I've switched it off/on for several times, went back to the old router/modem and powered it on again. After some hours I've checked the WebUI again: My probe is offline! :-( I've tested it again on the new router: Offline! Once again on the old setup: Offline! Untouched default router/modem from my ISP: Offline! Current LED status: (from 1-5; power to button) > on > off > slow blink > on > on SOS-DNS-history from Wireshark: (switch port mirrored to my analysis interface) > Standard query 0x0002 AAAA U.*************.sos.atlas.ripe.net > Standard query response 0x0002 AAAA 2001:67c:2e8:11::c100:1337 > Standard query 0x0003 A U.*************.sos.atlas.ripe.net > Standard query response 0x0003 A 193.0.19.55 The probe is online and communicates with many servers. Looks like the built-in tests are running fine. There is NTP, DNS, ICMP, UDP and HTTP traffic. But it's still offline at the WebUI. I've double and triple checked everything on my side. Any ideas what's going wrong? -- With kind regards, Christian Schrötter

USB drive
by Michael Ionescu 13 May '16

13 May '16

Hi all, I have a probe that's been down for several days now. I did contact RIPE about it, but support has been superficial. I also didn't yet find the level of technical detail I need in the information on the website and in this list's archives. The 8GB drive, when reformatted on a windows box with FAT32 as per support instructions, surprisingly only comes out with a 1GB partition. Inspecting the drive under linux, I find multiple partitions, with only the first containing an a fat32 filesystem: Platte /dev/sdc: 7927 MByte, 7927234560 Byte 244 Köpfe, 62 Sektoren/Spur, 1023 Zylinder, zusammen 15482880 Sektoren Einheiten = Sektoren von 1 × 512 = 512 Bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Festplattenidentifikation: 0xc3072e18 Gerät boot. Anfang Ende Blöcke Id System /dev/sdc1 2048 2099199 1048576 b W95 FAT32 /dev/sdc2 2099200 4196351 1048576 83 Linux /dev/sdc3 4196352 6293503 1048576 83 Linux On first glance, the others contain ext2 filesystems # fsck -N /dev/sdc? fsck von util-linux 2.20.1 [/sbin/fsck.vfat (1) -- /dev/sdc1] fsck.vfat /dev/sdc1 [/sbin/fsck.ext2 (2) -- /dev/sdc2] fsck.ext2 /dev/sdc2 [/sbin/fsck.ext2 (3) -- /dev/sdc3] fsck.ext2 /dev/sdc3 but on further inspections do not contain a valid magic number in their superblocks, so they are effectively unformatted. I would therefore suspect that they are not being used by the probe. Now the question: What is the correct layout supposed to look like (primary/secondary, size, ID, FS-type)? I would like to get my probe back up and running. Bonus question: What can I expect to find in point of files/data on the drive, that would tell me whether the probe was working correctly until I cut power and removed the drive? Thanks, Michael

LatencyMON Widget Y axis in milliseconds
by Marat Khalili 10 May '16

10 May '16

I'm using LatencyMON <https://atlas.ripe.net/docs/tools-latencymon/> widget to monitor my network performance. It's very convenient. Unfortunately, it always loads with latency shown in %% (of what?), not in milliseconds, so I have to make one extra click in order to view actual milliseconds. Is there some hidden switch that would make milliseconds the default? Shouldn't it be initially default in the first place? -- With Best Regards, Marat Khalili

An article/FAQ entry about probe troubleshooting
by Ondřej Caletka 02 May '16

02 May '16

Hi all, it seems that failing probes are getting more and more to be an issue, possibly due to USB flash drive failure. I think it would be nice if there was an article / FAQ entry with some official troubleshooting procedures, so we could just send a link to anybody complaining about non functional probe. Is there something like this on the roadmap? Perhaps we as the community could make something up: - how to check whether the port probe is connected to has proper IP and DNS parameters and is allowed to establish a SSH session to TCP port 443 in the Internet (beware of DPI firewalls that allow HTTPS but not SSH over 443) - how to check the LED status and the SOS list at the probe page (the current LED explanation in the FAQ is too techy and even power users like me still don't understand all presented states :) ) - how to diagnose USB flash drive failure, how to force reformatting the flash drive and how to replace it with a new one What do you think? Cheers, Ondřej Caletka CESNET

New on RIPE Labs: How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs
by Mirjam Kuehne 29 Apr '16

29 Apr '16

Dear colleagues, RIPE Atlas backend applications run on more than 40 servers. Each day these machines can produce thousands of application logs of any kind of severity level. In order to be able to track down serious errors, warnings or even unusual behaviour, we decided some time ago to try Elasticsearch as a logging sink. In this article we will look at the design of such a system and describe how we can easily make sense from an ocean of logs: https://labs.ripe.net/Members/andreas_strikos/how-elasticsearch-and-kibana-… Kind regards, Mirjam Kuehne RIPE NCC

Failure Rate on Atlas Probes
by Jonathan Brewer 23 Apr '16

23 Apr '16

Hi All, What's the known failure rate of Atlas probes, and the mean time before failure? At a guess 20% or more of the probes I've been working with have failed within their first year of deployment. Sometimes they come back with a power cycle, sometimes they don't. Regards, Jon

Probe status / self-help
by Robert Kisteleki 20 Apr '16

20 Apr '16

Dear All, Today we released a new feature intended to help the probe hosts detecting, understanding and fixing various issued related to probes. You should be able to see a new "Status" tab on your probe page. This is where we explain various conditions, such as USB problems, non-working IPv6 or DNS resolutions quirks. Please note that this bit is in early stages (officially labeled as beta). We believe it works in general, however for now it only explains various system tags that mark error conditions. It will have more features in the future. It is also intended to be a place where we can add features that explain, for example, "your probe behaves differently than the rest" or "path MTU issues detected" or such. We think this will be a useful feature to hosts. Let us know if you have specific suggestions for improvement. Regards, Robert Kisteleki RIPE NCC

API filtering for looking at measurements?
by Baptiste Jonglez 18 Apr '16

18 Apr '16

Hi, I would like to find measurements matching some specific conditions, so I tried to use the measurement API documented here: https://atlas.ripe.net/docs/rest/ However, filters don't seem to have the intended effect. For instance, I tried to restrict to a specific range of starting time: https://atlas.ripe.net/api/v1/measurement/?start_time__gte=1443654000&start… but looking at the first result (measurement ID 1411440), its start time is 1564618500, which is way outside of the requested range. Similarly when filtering by type: https://atlas.ripe.net/api/v1/measurement/?type=2 type=2 is supposed to be IPv4 traceroute, but the first result is measurement ID 1001, which is an IPv4 ping. Am I using the API incorrectly, or is there a bug somewhere? Thanks, Baptiste

Introducing the RIPE Forum
by Vesna Manojlovic 12 Apr '16

12 Apr '16

Dear colleagues, There’s a new way to participate on the RIPE Atlas mailing list! We are introducing the RIPE Forum, a web-based interface for reading and sending emails on RIPE community mailing lists. We developed the RIPE Forum in-house based on feedback we received from members of the RIPE community who wanted the option to interact and share information in a more modern way. But it’s important to note that this new interface is completely optional – those who like using the established mailing list system can continue on as they always have, and won’t notice any difference. RIPE Atlas mailing list will be the first one. We have plans to make the RIPE Forum available for other RIPE Community mailings lists after the RIPE 72 Meeting in May. If you’re interested, you can start using it here: https://www.ripe.net/participate/mail/forum/ We created a special mailing list for testing purposes, so that any conversations about the platform itself can be contained there without disrupting the regular flow of discussions on the RIPE Atlas mailing list. Feel free to send test messages and try out the RIPE Forum on this special list: https://www.ripe.net/participate/mail/forum/ripe-forum-test Learn more how the forum works and the background of the project: https://labs.ripe.net/Members/marco_schmidt/introducing-the-ripe-forum The forum is still in "beta" status – there are likely still some bugs and we are continuously working to improve things, so please keep that in mind while exploring the forum. You can give your feedback by clicking on the “Report a bug” button on the forum, or leave a comment on the above RIPE Labs article. We hope you’ll enjoy the RIPE Forum, and look forward to your feedback! Kind regards, Vesna Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Failing 4GB USB on v3 probes?
by Phillip Remaker 11 Apr '16

11 Apr '16

So far, I have had two of the SanDisk Cruzer 4GB drives (SDCZ33) fail, and I think I have two other ML-3020 (v3) devices with the same fate. Case #1, the drive fell into read only one. Case #2, the drive identifies to the USB, but read of block 0 (capacity) fails. The first time I called SanDisk and jumped through their hundred hoops to replace it.They were reluctant since I couldn't produce a receipt. This time, I just grabbed an old 8GB USB and dropped it in. Looks like it only uses 3GB. Does Atlas plan to pursue warranty claim, or is this an acceptable failure level for the probes?

Flow-id of built-in traceroute measurement
by Wenqin SHAO 08 Apr '16

08 Apr '16

Dear list, I have some questions concerning the flow-id of built-in traceroute measurements and are seeking for your help. As many of you may have already noticed, the flow-id of the built-in traceroute measurement periodically varies form 0 to 15, in a circular manner. With this behaviour, it is supposed to reveal the diversity of underlying IP paths. In the case that there are more than 16 unique IP paths between a source and destination pair, could this scheme reveal all of these IP paths? If it can, which leads to more than one IP paths per flow-id? Is it normal, from a load balancer point of view? If it can not, then why not a wider range of flow-id (more nuances in header hash results), say [0, 63]? Is it related to common realisation of load balancer? Many thanks in advance. Best regards, Wenqin ==== Wenqin SHAO PhD Candidate Telecom ParisTech
