ntp built-in measurements?
by Bajpai, Vaibhav 04 Nov '15

04 Nov '15

Dear RIPE Atlas, Do the probes not run (new) NTP measurements as built-in measurements? — I was glancing over the measurement data pushed by my probe, but I do not see any NTP measurement data. Although, when I try to provision a UDM, I do get an option to schedule an NTP measurement. Thanks! Best, Vaibhav ===================================================== Vaibhav Bajpai Room 91, Research I School of Engineering and Sciences Jacobs University Bremen, Germany www.vaibhavbajpai.com =====================================================

Question about the hardware
by Micha Bailey 30 Oct '15

30 Oct '15

I just got my Probe, and I was wondering what the thought/planning process was when they were designed. Why use a $40 wireless router/access point? I would have thought that cheaper options would be available that provide the requirements (processor and a network port).

Hi, It seems the 'new set wizzard' for selecting probes is not working anymore. It does show the map but the input box is missing. Is it just me or is it broken? Thanks, Dave

Probe not appearing in the Atlas
by Ismael Carmona 28 Oct '15

28 Oct '15

Hello, We have the probe #24142, it gets DHCP fine (91.123.100.8) and we can ping it and see with sflow that it perform requests to external servers but we cannot find it online in the atlas. We already tried rebooting it. Any idea how we can make it appear online in the atlas page? Thank you, Ismael

traceroute - view latest results
by gboonie 27 Oct '15

27 Oct '15

What should the blue 'i' do at the right side of a traceroute measurement? Hovering over it shows a 'view lastest results' message. For example in this measurement: https://atlas.ripe.net/measurements/2845726/#!probes I'm hoping it will soon display all the hops of a traceroute. Just like the traceroutes of the built-in measurements. Just like: Thanks, Dave

filter ping results by AS

Hi there, I'm currently trying to figure out, how I can get all ping results to(/from) my AS within a certain time frame, to run some statistics. The REST-API documentation [0] states, that measurements can be filtered by dst_asn, but it doesn't seem to influence the results I'm getting: > filter: { > 'start_time__gt': 1445231337, > 'type': 'ping', > 'dst_asn': 553 > } > > dst_asn dst_name > -------------------------------------------- > 2607 sk-bts-as2607.anchors.atlas.ripe.net > 2602 lu-lux-as2602.anchors.atlas.ripe.net > 16154 88.213.204.251 > 1853 at-vie-as1853.anchors.atlas.ripe.net > 8608 195.18.114.5 > 32475 www.siteground.com > 12322 78.194.137.59 > None ch-zrh-as559.anchors.atlas.ripe.net Also, why do some measurements have no dst_asn?

Private Probes: What's the Point
by Jonathan Brewer 24 Oct '15

24 Oct '15

Hi All, I've run into a few probes marked private, and when I've found & asked the owners, they didn't realise they'd done anything restrictive or harmful to researchers by marking their probes private. Intrigued at this phenomena, I had a look at the probe metadata. Right now I think there are 1,534 Atlas probes that are active and connected to the network, but marked private. What's the point of having private probes in the network? Do their hosts still earn credits they can use on public probes? Should they be? Are private probe hosts helping the project? The FAQ says nothing about private probes, so I thought I would ask here. Thanks, Jon

Anchors and NTP back to the future
by Stephane Bortzmeyer 23 Oct '15

23 Oct '15

Some anchors appear to be reachable with NTP but most of them are not. I guess it means the anchor always has a NTP server (and I assume it is on purpose) but many networks filter it. What is the good recommanded practice? Specially in the light of the Back to the Future attack <http://www.cs.bu.edu/~goldbe/NTPattack.html>

Public vs. Non-Public Probes
by Vesna Manojlovic 22 Oct '15

22 Oct '15

Hi Jonathan and others, Thanks for bringing this point up again. I hope others will feel free to join in the discussion. As Wilfried mentioned, we did have a discussion about public and non-public probes some time ago. Here are the relevant posts: RIPE Labs article proposing making RIPE Atlas probes and measurements more public: https://labs.ripe.net/Members/becha/proposing-making-ripe-atlas-data-more-p… Discussion on the ripe-atlas list: https://www.ripe.net/ripe/mail/archives/mat-wg/2013-December/000399.html Conclusion: https://www.ripe.net/ripe/mail/archives/mat-wg/2014-March/000436.html Consequences: new terms & conditions, with more clarification on this topic: https://labs.ripe.net/Members/becha/ripe-atlas-moving-to-production-service & https://atlas.ripe.net/legal/terms-conditions/ As you can see from the discussions above, some RIPE Atlas users felt it was important to retain the choice of marking their probes “non-public”. We do encourage all RIPE Atlas users to mark their probes “public” for the greatest benefit to the community, and the majority of probes are public. However, non-public probes are still used both for built-in measurements and user-defined measurements; they are just not listed on the web or API. Once a user decides to plug a probe into their network, IP address information can no longer remain "private". This is why we prefer to refer to them as “non-public” probes rather than truly “private” probes. Of course, we care very much about protecting probe hosts’ privacy and we never make personal information like email addresses or MAC addresses public. There is some more information about this in the FAQs on the RIPE Atlas website under the answers to "Will my IP address show up in measurements done by my probe?” and "Is the measurement data made public?”, but the RIPE Labs article referenced above contains the most detailed information on the topic. Thanks again for your thoughts on this, and please let us know if you have any other questions or comments. Regards, Vesna

Prove v3 not connecting after powercyle
by Jeroen Bogers 20 Oct '15

20 Oct '15

Hi all, Two days ago I had to powercycle some of my network equipment, including my Atlas V3 probe. After the powercycle, the probe did not come back online. After booting, the first and second light (power and the one next to it) remain lit (not blinking). This is not a state that is listed in the FAQ: https://atlas.ripe.net/about/faq/#what-do-the-lights-on-the-side-of-the-pro… The only status that comes close is the 'Running from built-in flash' state, but led 2 should be blinking then? Does someone here have an idea what is wrong with my probe (and how to fix it)? I already tried connecting it to a different network port and power source, but this did not make any difference. The switch port the probe is connected to does light up, so the Ethernet port seems to be functioning. With kind regards, Jeroen Bogers

[Feature Request] Show probe address on failure notifications
by Brian Rak 16 Oct '15

16 Oct '15

I recently received one an email indicating one of my probes is offline: This is the second reminder that your probe (#20689 ) is not connected to our infrastructure and has been disconnected since 2015-09-14 09:37 UTC. Could you please check whether everything is set up correctly on your side? If it is, and your probe is still reported as disconnected when you log in at https://atlas.ripe.net, please reply to this email so that we can follow up. Is there any way these can be modified to include further information (like the probe's address, or basically anything about it)? Probe 20689 means nothing to me, so I have to log in to take a look at exactly what it is, and where I need to go to fix it.

Dear colleagues, Please find a new article on RIPE Labs: https://labs.ripe.net/Members/ray_bellis/researching-f-root-anycast-placeme… In order to expand the reach of F-root, Ray Bellis looked at where queries to F-root are coming from and where it would make most sense to place new nodes. As a first step, Ray looked at the existing nodes to see how they behave and if there is anything that can be improved. He used RIPE Atlas to do this. Kind regards, Michela Galante RIPE NCC

3rd generation probe doesn't appear as online
by Thiago Ayub 08 Oct '15

08 Oct '15

Hi, I receive a week ago our first probe but I'm unable to make it appear as online at the website. I can see it requests DHCP, it gets an IP address (NATed), it does some measurements (like HTTP and NTP) successufly but at atlas.ripe.net it is listed as 'Never online'. It rebooted around 3 times in the last week and each time was kept as least 24h in a row with no power down or cable disconnect. The MAC ADDRESS at the website matches with the MAC ADDRESS labeled in the probe. How should I proceed to get this fixed? Best regards, Thiago Ayub

Permanent private measurement
by Lorenzo Colitti 08 Oct '15

08 Oct '15

Hi Atlas folks, I'd like to use my probe to monitor the status of my home Internet connection by continuously pinging my ISP's network (which is not the first or second hop in traceroute, but something like the sixth) and perhaps www.google.com. Is there a way to do this easily using the existing UI and tools? I couldn't find any existing measurements for this. I can look at the built-in v4 and v6 measurements for K-root, which is normally very close to me, but that's not 100% representative of the status of my Internet connection because it also measures the peering exchange link between my ISP and K-root. Cheers, Lorenzo

probe probed
by Gary Gapinski 02 Oct '15

02 Oct '15

Saw my first IPv6 port scan recently, targeting my domestic Atlas probe. Originated from Shodan, first seen 2015-09-30T2017Z, and again ~24 hours later. At the moment, the probe is behind a stateful firewall (which dropped the traffic). Does it make any difference if it were moved to be completely exposed? (I've often wondered whether this should be the case to ensure proper function.) It is behind (filtered) NAT on the IPv4 side. Regards, Gary

Possible reasons behind a failed measurement
by Wenqin SHAO 28 Sep '15

28 Sep '15

Dear list, I recently launched a ping measurement that selects 50 anchors worldwide for a period of 24 hours, id 2439518. The measurement failed with no probe allocated to it. Do you have any clue on the possible reasons for that? One of my guesses is that anchors are highly demanded and non of them were available during the measurement window. I’d love to hear you thinkings on this matter. Many thanks for your attention. Best regards, Wenqin Shao ---- Ph.D candidate Telecom ParisTech

Question about unstable power and probe
by Anurag Bhatia 27 Sep '15

27 Sep '15

Hello everyone! I have recently deployed a probe in a place where there's unstable power. Probe is rebooting like 4-5 times a day and unlikely power would be fixed in near future. I was wondering if it's safe for probe at all. Does anyone has experience with 4-5 reboots a day with probe? Will probe sustain it or better I just disconnect it and rather wait for power to become stable? Curious to hear your experiences. Thanks. -- Anurag Bhatia anuragbhatia.com PGP Key Fingerprint: 3115 677D 2E94 B696 651B 870C C06D D524 245E 58E2

RIPE Atlas Tools and Python versions
by Daniel Quinn 24 Sep '15

24 Sep '15

As some of you may already know, we’ve been working on a new command-line toolkit that will let you do nifty things like: * List measurement and probe metadata * Generate reports from measurement results * Stream measurement results It’s coming along quite nicely, but I’m running into just too many cases where support for Python 2.6 is (a) making my job harder, and (b) making my code uglier. Given that (a) means I spend more time fixing compatibility rather than adding features and (b) just makes me sad, I wanted to ask the community how important Python 2.6 is to you. So here’s the question: Of those of you who would find such a tool interesting/useful, how many of you *only* have access to a computer running Python 2.6? Such systems include CentOS distributions earlier than 7, and corresponding RedHat Enterprise systems. If you’re using Debian, or Ubuntu, you should already have 2.7 by default, and if you’re on Gentoo or Arch, you probably have both 2.7 and 3.5 already. I understand that Apple’s OSX is running 2.7 these days as well. If I don’t get a wave of messages about how very important 2.6 is to your collective health and wellbeing, I’m going to consider this a non-issue and drop support for 2.6. Thanks for your input everyone :-)

Friday's events on RIPE Atlas
by Romeo Zwart 23 Sep '15

23 Sep '15

Dear all, Here is a description of the events that took place last Friday and some 'lessons learned' that we took away from it. The high level summary of events is that an Atlas user was authorised to create an extreme number of measurements involving a large number of probes. This effectively overloaded the back-end machinery in various different ways. Even though this event could only happen because of the exception in resource use limits, we have implemented workarounds and countermeasures to avoid a repetition in future, and we will be investigating some of the more fundamental issues in the coming period. More information is available below for those interested. Observations: - Problems started shortly before 11am when one of the Atlas users created a large number of new measurements each involving all available probes. The user had been given an exceptional amount of credits as part of a special experiment. Therefore the normal limitations on the impact any individual user can have on the system were not active when the measurements were created and activated. - The results of the newly created measurements put a lot of strain on the measurement scheduler, which triggered our interest. After some investigation the cause of the overload was identified and the related measurements were ended. - However, by this time the majority of results, up to that moment, had already reached our queuing servers and the consumers were already ingesting the results into our Hadoop storage platform. - At this phase we discovered a capacity problem with the process that consumes the Atlas results, so we doubled the capacity of that component on the fly. - This exposed the next bottleneck in our platform in the form of an accumulation of the created results on a very small number of processing nodes. Normally the incoming measurement results are distributed over several storage nodes, so this strongly reduced the consumption rate of new data. - A third factor that contributed was the fact that, in attempt to curb growth of the Atlas data, we have migrated the Atlas data sets to a more efficient compression algorithm earlier in the year. This saved us some 40-50% of storage space for the Atlas data, at the expense of some compute power. Under normal circumstances, even at high loads, this compute power is abundantly available on the storage cluster. Under the specific circumstances of last Friday's events, it turned out that the change of the compression algorithm had increased processing time for some Hadoop system tasks by up to a factor of 8, which had a direct impact on the data consumption speed. Immediate actions taken: - Removed special privileges of the end-user in question - Added capacity to the Atlas consumer processes - Returned (temporarily) to less efficient compression on the Atlas data sets. Lessons learned and further planned action: - Granting special privileges for some of the Atlas users needs (even) more attention than it already receives. - We need to better communicate "best practices" to these power users so they can use their extra allowances responsibly. - Improved compression of Atlas data has decreased our storage demands but also decreased our processing capacity. This needs further investigation to find the optimum configuration. - Investigate possibilities to better spread incoming results over more worker nodes (reduce hotspots). - Investigate and quantify reasonable boundaries of scalability of the whole system, to guide the limits for granting credits to end users. Kind regards, Romeo Zwart

Question about "location setting" of RIPE Atlas
by Anurag Bhatia 15 Sep '15

15 Sep '15

I have been hosting one of RIPE probes and recently I have switched over my ISP. Basically my previous ISP provider was regular ISP network with full L3 PoPs nearby but in my new setup I have got a point to point to a city 900km away and getting IP transit over there. Now under such case, I am "technically" customer of that network. Should I still keep my location as I have current one or better update it to that new location 900km away? The latency of course is low (as it is provisioned on fiber and hence just 20ms roundtrip) but I think it will confuse off stats if anyone considers to use this probe for any data in my region. What you all think? Can someone recommend on correct location? Thanks. -- Anurag Bhatia anuragbhatia.com PGP Key Fingerprint: 3115 677D 2E94 B696 651B 870C C06D D524 245E 58E2

Probe management sharing - LIR
by Abreu, Alexandre, Vodafone Portugal 08 Sep '15

08 Sep '15

Hi all I've shared the management of my probes using the LIR option. It worked fine for 2 LIR users (one of them is me and I now see the probes as "mine" and "shared with me") but one other LIR user doesn't see anything unless I specify his username explicitly. What kind of users are these? Aren't these the LIR users we can add on the LIR portal? Thanks in advance. Alexandre Abreu
