Emails Regarding Probe Connection Issues
by Alun Davies 17 Nov '16

17 Nov '16

Dear members of the RIPE Atlas community, It was recently called to our attention that certain emails we send out to RIPE Atlas probe hosts, concerning probe connection issues, have been somewhat abrupt in their tone. We are working to address the issue. While we devote a great deal of effort to ensuring that any correspondence we send out is both informative in content and appropriate in tone, we greatly appreciate feedback whenever it is felt that such goals have not been met. We would like to take this opportunity to once again thank all RIPE Atlas probe hosts for their ongoing participation. Best regards, Alun Davies (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

Probe not taking UDMs for months but no issue reported
by gboonie 06 Nov '16

06 Nov '16

Hi, My probe 24434 had an issue without me being aware because there was no notification. But even if there was, it was hard to detect. The only reason I found out was because I looked at a long running measurement that did not return data. On the other side, the built in measurements seemed fine. So first though was that something prevented the probe to perform DNS tests to the network's resolvers. I've attached a laptop to the connection but all worked fine. So rebooted the probe and found that the USB storage went to read-only. But why does it only detect this after a reboot? This probably means that the probe probably only checks at startup what the status is of the USB key. The other thing that is odd is that the probe kept earning credits. Here is a graph with the proof that it did stop taking UDMs early august. *My request: Please improve the probe's detection of issues. I do not mind replacing a USB dongle at all but I do find it annoying that the probes can be in this state where it is not down but also not taking any UDMs.* Thanks, Dave Proud owner of 3 probes.

Probe reconnecting problem
by Nils Ohlmeier 03 Nov '16

03 Nov '16

Hello, is there any known problem around probes reconnecting after the uplink connectivity got lost? My probe was offline for several days even though my local network worked fine. I'm assuming that the uplink was dead for some time. And I waited a few days to see if the probe would recover by itself, but eventually gave up and power cycled it. Is there anything I could do to debug such a problem in case it should happen again? Cheers Nils

Hi Team, It'd be great if you could change the tone of the alert messages below. Admit some fault. Ask for help. The majority of disconnects I've seen have been due to device failure, nothing to do with " everything is set up correctly on your side" and messages like this do nothing to encourage me or the networks I've convinced to host probes to help fix the problems. It really hurts that I've lost so many probes that took so much effort to get installed - and these messages don't help.

Actual measurement interval much larger than planned
by Wenqin SHAO 20 Oct '16

20 Oct '16

Dear list, I encountered some cases where the actual time interval between two neighbouring measurements being much larger than the scheduled value. Have you witnessed similar cases? I appreciate explanations on underlying reasons. Here goes an example: from ripe.atlas.cousteau import AtlasResultsRequest filters = dict(msm_id=1010, probe_ids=[16981], start=1470055258, stop=1470056217) is_success, results = AtlasResultsRequest(**filters).create() if is_success: for mes in results: print mes.get('timestamp', -1) The above code requests some built-in ping measurements (240s interval) made by probe 16981 and prints their timestamps. See below for the execution result: 1470055259 1470055499 1470055978 1470056216 Four measurements are retrieved within the given time range. I noticed that time interval between the 2nd and the 3rd measurement is 479s much larger than the planned value 240s. How come? Many thanks for your attention. Best regards, wenqin

probe offline - troubleshooting requested
by Andre Heinrichs 18 Oct '16

18 Oct '16

Last night my probe (#29384) was declared offline after the daily Internet disconnection my FritzBox executes to keep the provider from disconnecting me after 24 hours online. According to the SOS history the probe gets DNS requests out but somehow fails to connect completely. I tried rebooting every network component i could locally get my hands on but that didn't seem to help much. The LEDs on the probe don't actually fit any of the descriptions from the FAQ: They are On, Off, fast(er) blink (at least if compared to shortly after booting (Network Test?), On, On. I'm guessing it means the network somehow managed to fail. Although I don't notice anything missing from what I did on the network this morning. Any ideas what I could try to get the probe reconnected? Just to be complete: Here are the last lines of the SOS history: 62.109.121.35 2016-10-18 05:43:27 A 3h 59m 62.109.121.35 2016-10-18 05:43:27 AAAA 3h 59m TIA, Andre, currently not in reach of the probe

Shall we continue non-public measurements in RIPE Atlas?
by Mirjam Kuehne 18 Oct '16

18 Oct '16

Dear colleagues, "Non-public measurements" is a feature of RIPE Atlas that allows users to use the infrastructure to measure things while not sharing those results with the public. Is that still a useful feature? Should it exist in the future?

Temporary Reduction of Available History on RIPE Atlas and RIPEstat
by Romeo Zwart 18 Oct '16

18 Oct '16

Dear colleagues, Today, Tuesday, 18 October 2016, between 09:00 and 10:00 UTC, the back-end storage cluster for RIPE Atlas and RIPEstat will be switched to a backup environment. This is part of planned maintenance work. The backup facility has a more limited amount of storage space, which means that RIPEstat and RIPE Atlas, including specific applications like DNSMON and DomainMon, will not serve data older than one year. We expect this to have no impact on ongoing RIPE Atlas measurements, scheduling new measurements, or the retrieval of more recent data from RIPE Atlas, RIPEstat or DNSMON. We apologise for any inconvenience. Kind regards, Romeo Zwart

Out of date system probe tags
by Chris Amin 17 Oct '16

17 Oct '16

Dear all, Some of you have noticed that certain system tags (see below) remained applied to probes when they should have been removed. This is because the process that adds and removes these tags was temporarily disabled following the service issues that we experienced earlier in the month. This process has now been re-enabled after verifying that it was not a cause of the service downtime, and these tags have been applied correctly. The affected tags were: * Flaky connection * Firewall problem suspected * DNS problem suspected * No flash drive * Readonly flash drive * Hardware problem suspected Kind regards, Chris Amin RIPE NCC

firmware download test?
by Yang Yu 12 Oct '16

12 Oct '16

Hi, I have 2 probes that are connected but shown as offline even after several power cycles. I performed USB stick troubleshooting procedures by removing the USB stick and saw NO-USB SOS message. But after inserting the USB stick there wasn't any new SOS messages. Plugged the USB stick to computer and saw corrupted file system. Formatted the stick and inserted it back, still no SOS messages. What kind of filesystem layout is expected on the stick? From what I read the probe should automatically partition/format the stick. Maybe the stick is bad. I do see a good amount of packet loss between the probe's network and the registration server. How robust is the firmware download process (e.g does it abort on TCP RST)? Is there any way to manually load the firmware? Thanks. Yang

Inconsistent system tags
by Johannes Matheis 30 Sep '16

30 Sep '16

Hello, I got IPv6 connectivity for my probe 4365 a few days ago (2016-09-26) when I first noticed the system tag "IPv6 Doesn't Work". As the system tags aren't updated more often than every four hours I started some successful IPv6 measurements on that probe and settled back for four days. Now the probe is still flagged as IPv6 not working. In the meantime I noticed the tag "v2" but the general information tab tells me the system architecture is probev1… Actually I don't know if it's a v1 or v2, but it's still an old Lantronix one, so it's not completely wrong :-) Is there a possibility to re-trigger the assignment of the system tags for this probe or some other solution? Thanks! jomat

Making public probes’ IP addresses public in web interface
by Andreas Strikos 30 Sep '16

30 Sep '16

Hello, We made a change a few weeks ago to the RIPE Atlas web interface to align it more closely with the API. As a result, you can now see the IP addresses for public probes, regardless of whether you are a logged in user or not. This information is displayed on the public probes’ detailed information pages, under the “Network” tab. Previously, public probes' IP addresses were not shown, even for logged in users. Nothing has changed in the API or the web interface for probes that are not shared publicly. We understand that some of you were surprised by this change and we apologise for not communicating it earlier. However, I want to make it clear that the IP addresses of public probes have always been available via the API, whether you are a logged in user or not. We decided to include it via the web interface so that our users could access the same information regardless of which interface they decide to use. RIPE Atlas is meant to be a public platform that openly provides data to everyone interested. In this spirit, we encourage everyone to make their probes public. However, if you decide that you *don’t* want to share your probe publicly, you can change this setting by going to your probe’s detailed information page (go to "My Atlas" and click on your probe’s ID), clicking on the “Edit” button under the “General Information” tab, and deselecting the “Shared Publicly” box. Please note that personal information such as MAC addresses and email addresses will never be shown, regardless of whether you decide to share your probe publicly or not. You can learn more about what information is made public in RIPE Atlas in this RIPE Labs article: https://labs.ripe.net/Members/becha/proposing-making-ripe-atlas-data-more-p… Please let us know if you have any questions or concerns.

We also believe that measuring networks before and after they enable IPv6 provides useful data. IPv4-only anchors are clearly marked as such, and we will implement checks to ensure these anchors become IPv6-capable as soon as their ASNs begin announcing IPv6. In the meantime, the RIPE NCC will continue to actively promote IPv6 deployment through our training courses, IPv6 Act Now website, IPv6 Roadshows and other programs, and our IPv6 Program Manager will follow up with any hosts requesting an IPv4-only anchor to help them in any way possible. We believe that supporting IPv4-only anchors will provide a more comprehensive understanding of the Internet and that the entire Internet community will benefit from more measurement data. You can learn more in this RIPE Labs article: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ipv4-only-ripe-atlas-an… Interested in hosting a RIPE Atlas anchor? Learn more: https://atlas.ripe.net/get-involved/become-an-anchor-host/ We are particularly interested in deploying anchors in the Middle East, Western Asia, Latin America and Africa in order to add more geographical diversity to the measurement data. There are several organisations that want to host a RIPE Atlas anchor but don’t have the necessary funding. To learn more about sponsoring an anchor, or for any other questions, please contact us at atlas(a)ripe.net And don’t forget to let us know if you’re doing something interesting with RIPE Atlas data - we always want to hear about your use cases, research and experiences!

Is there a > way to increase the limit? yes, ask the team at atlas(a)ripe.net (cc-ed). the folks there can extend limits (not unlimited of course, these limits are there for a reason :) ), but would need some info from you: - what is the experiment you'd like to perform - what would you want the new limit to be (and why what you want to do can't be done with the current limits and/or existing measurements) - when does your experiment end (ie. when can we put the limits back to the default) - promise us that you'll acknowledge RIPE Atlas in a paper - send us a link/copy of the paper once it's published (i hope i'm not forgetting things :) ) cheers, emile

API probe search
by Hank Nussbacher 08 Sep '16

08 Sep '16

When searching for specific ASN probes via: https://atlas.ripe.net/probes/ and entering a search like "ASxxxx", why does the API ignore the letters AS and respond with probes that have an id of yxxxx or xxxxy or ASN yxxxy? Shouldn't it be if I specify a specific string of ASxxx the response should be *only *those probes in ASxxx or at the worst also ASxxxy? Thanks, Hank

Data delays on RIPE Atlas
by Romeo Zwart 08 Sep '16

08 Sep '16

Dear colleagues, We are performing some maintenance work on the backend clusters supporting RIPE Atlas. Unexpectedly, this is having an impact on the insertion speed of new data. This means that new data insertion is behind for a few hours. The maintenance work is expected to complete before the end of the day, at which point the backlog of data will be cleared up very quickly. We apologise for any inconvenience caused. Kind regards, Romeo

Changes in LatencyMon
by Marat Khalili 05 Sep '16

05 Sep '16

Dear list, LatencyMon <https://atlas.ripe.net/docs/tools-latencymon/> changed for me recently with only minimum latency value shown now instead of all three. I wonder if other people see this and what are the reasons behind the change? (Cannot say yet if changes are for better or worse, but I can find no announcement and so suspect that this can be unintentional.) -- With Best Regards, Marat Khalili

Reconnecting probe 3508 - troubleshooting
by Michael-John Turner 24 Aug '16

24 Aug '16

Hi I've just reconnected probe 3508 to the network after a number of years offline (I think it was last online in November 2012?). Under the SOS history, I can see that it's making DNS queries successfully (using the DNS servers it receives by DHCP), but it's not connecting correctly to the RIPE network. The following is also displayed under SOS history: "This probe cannot connect on port 443 (HTTPS)". Any thoughts on where I can start troubleshooting? For test purposes I've connected the probe to my LAN, with full internet access. Cheers, MJ -- Michael-John Turner * mj(a)mjturner.net * http://mjturner.net/

Atlas Sagan error_message
by Wenqin SHAO 24 Aug '16

24 Aug '16

Dear list, I was using ripe.atlas.sagan to parse some ping measurements, one of them looks like the following in JSON format: rec = {u'af': 4, u'prb_id': 15843, u'result': [{u'error': u'connect failed: Network is unreachable'}], u'avg': -1, u'size': 20, u'from': u'88.174.18.20', u'proto': u'ICMP', u'timestamp': 1470009620, u'dup': 0, u'type': u'ping', u'sent': 0, u'msm_id': 1010, u'fw': 4730, u'max': -1, u'step': 240, u'src_addr': u'192.168.0.22', u'rcvd': 0, u'msm_name': u'Ping', u'lts': 641089, u'dst_name': u'192.228.79.201', u'min': -1, u'dst_addr': u'192.228.79.201'} Suppose that the above measurement is stored in a variable called rec as a dict, and I parse it using PingResult: from ripe.atlas.sagan import PingResult parsed_rec = PingResult(rec) I was expecting a no-empty string for parsed_rec.error_message, as we can see the measurement result contains an error string, however the parsed_rec.error_message is None. type(parsed_rec.error_message) <type 'NoneType’> Probably I misunderstood some part of the doc: error_message str If the result is an error, the message string is in here Could someone please clarify the exact functionality of this error_message? Many thanks in advance. Best, wenqin

Probe 10973 problem
by Vladislav Solovei 17 Aug '16

17 Aug '16

Hi. I have connected probe 10973 (which was offline several years) to the network. Firmware updated from 3.3.8 to 4010. "Status" said that "Your probe is currently connected." But on probe page i see the message: "Note: this probe is most likely not operational, and as such it has been written off as of 2013-12-03 15:44 UTC. The most likely reason for this is that the host could not be contacted." It is ok? :) Do i need to upgrade FW to latest version (tried to reboot probe several times, but fw version still 4010)?

Alternative to jq: gron
by Stephane Bortzmeyer 16 Aug '16

16 Aug '16

It seems many people here use jq to browse JSON files. I've been referred recently to gron <https://github.com/tomnomnom/gron> which is quite different: less features but probably simpler to use for beginners. Unlike jq, gron does not have a filtering language: it just formats the JSON in a way that makes simple to use traditional grep. Here is an example with measurement #4477822, a DNS one: % gron 4477822.json|more json = []; json[0] = {}; json[0].from = "178.248.214.8"; json[0].fw = 4730; json[0].group_id = 4477822; json[0].lts = 18; ... Selecting the values of the serial number is as simple as: % gron 4477822.json | grep SERIAL json[0].resultset[0].result.answers[0].SERIAL = 2223898795; json[0].resultset[1].result.answers[0].SERIAL = 2223898793; json[1].resultset[0].result.answers[0].SERIAL = 2223898790; json[1].resultset[1].result.answers[0].SERIAL = 2223898792; json[1].resultset[2].result.answers[0].SERIAL = 2223898795; json[2].resultset[0].result.answers[0].SERIAL = 2223898791; ... And you can turn back the result of the filtering into JSON.

Probe down - USB?
by İhsan Doğan 13 Aug '16

Hi, My probe went down this morning. Probably I'm running into the issue with the USB stick. I was thinking to replace the USB stick. Are there any special requirements (size, speed, etc.) for the USB stick? -Ihsan -- ihsan(a)dogan.ch http://blog.dogan.ch/

Awarding credits for measurement results
by Robert Kisteleki 04 Aug '16

04 Aug '16

Dear probe and anchor hosts, When you create measurement results in RIPE Atlas, you’ll now get a little something extra back in the form of credits. From now on, we’re giving all RIPE Atlas probe and anchor hosts one credit back for every measurement result they generate. This means that most probe hosts will earn up to an additional 10,000 credits (50%) per day on top of the credits they get for keeping their probes online, anchor hosts will earn an additional roughly 200,000 credits (100%) daily, and DNSMON anchor hosts will receive roughly 1,000,000 additional credits. This is our way of rewarding the probe and anchor hosts who contribute the most to RIPE Atlas - enjoy! Regards, Robert Kisteleki RIPE NCC
