10 Sep '14

Dear RIPE Atlas users, We're happy to announce that another RIPE Atlas anchor joined the network and is now available as a target for probe hosts conducting their own user-defined measurements. The new anchor is called sg-sin-as133165 and it is hosted by DigitalOcean in Singapore City, Singapore. Congratulations to DigitalOcean for their third anchor online! Anchoring measurements (ping, ping6, traceroute and traceroute6) are scheduled towards this anchor from all the other anchors as well as several hundred probes, providing a continual overview of regional reachability. Results of these measurements are available as raw data in JSON format, and visualised on the map and "seismograph" with many configurable features. You can access the anchoring measurements for all anchors at: https://atlas.ripe.net/anchors/list/ Learn more about RIPE Atlas anchors at: https://atlas.ripe.net/about/anchors/ Thank you for participating in RIPE Atlas!

Probe on a /31 or /32 IPv4 network
by Baptiste Jonglez 18 Aug '14

18 Aug '14

Hi, We would like to deploy our Atlas probe on a separate L2 network, but without having to spend 4 IPv4 addresses (i.e. a /30 network). Using a /31 would be nice, but the web UI doesn't allow it as static IPv4 configuration ("The Gateway address should be different from the ending network address"). Would it be possible to allow /31 in the web UI? I believe the probes themselves support it. Even nicer would be support for /32 networks, even though it is perhaps less usual. This can easily be done with iproute2 on Linux, assuming the probe is 192.0.2.48/32 and its gateway is 192.0.2.1: ip addr add 192.0.2.48/32 dev eth0 ip route add 192.0.2.1/32 dev eth0 ip route add default via 192.0.2.1 or even shorter: ip addr add 192.0.2.48/32 dev eth0 ip route add default via 192.0.2.1 onlink dev eth0 Using a gateway that is not on the same subnet doesn't sound very nice, but again, the goal is to avoid wasting precious IPv4 space. Thanks, Baptiste

Probe suddenly lost IPv6 connectivity
by Ondřej Caletka 11 Aug '14

11 Aug '14

Hi, strange thing happened today. My probe v2 #3467 suddenly lost IPv6 connectivity and reconnected to the control server using IPv4. The probe does not even respond to ping6 ff02::1%eth1 sent from the router. I wonder what could cause such behavior. I will try to reboot the probe once I'll reach it. -- Ondřej Caletka

Probe 2092 shown as offline for a month
by David Precious 06 Aug '14

06 Aug '14

Hi there, My v1 probe #2092 has been showing as offline for a month, despite being powered up and pinging. Yesterday I power-cycled it, and it came back up and answers pings again, but the Atlas control panel still shows it as disconnected. Is there any troubleshooting I can do to get more information? I've verified that I can ping it from my internal network. There's no egress filtering which would be blocking it from talking outbound. I've just had my router log new outbound connections then power-cycled the probe again. I saw it successfully obtain an IP via DHCP (10:13:21), then 31 minutes later, connected to oneill.atlas.ripe.net (193.0.19.12) on port 443 (10:44:50) (UK times). I have verified that another box on the same network can connect to that IP & port: [davidp@columbia:~]$ telnet 193.0.19.12 443 Trying 193.0.19.12... Connected to 193.0.19.12. Escape character is '^]'. SSH-2.0-OpenSSH_5.3 Anything else I can do to provide more useful info?

Re: [atlas] [ripe.net #1133019] Re: Your RIPE Atlas Probe (ID: 16784) is not connected to our network
by Daniel Suchy 01 Aug '14

It's surprising, that you can't manage probe remotelly when it isn't "connected" (even you can directly reach it on L3). Technically, probe runs on Linux, so you can have SSH daemon with restricted IP access running here (listenning daemon has minimal performance overhead) - by current "behavior" you simply loose any way to diagnose problem - and dependence of established tunnel is another layer, which can fail... As stated before - simple rebooting is just a *workaround* of any issue, not a solution (but it seems that's your basic recomendation). I think you should work on improvements on probe diagnostics in such cases - new hardware versions of probes seems to be more problematic compared to older probes, as I can see also on atlas mailing list. I remember, that I had to plug out/in USB flash as some step with probe before (also your recomended "solution"). Also on probe should run some kind of watchdog, which reboots probe in case of similar problem automatically - probably it doesn't run now...

Re: [atlas] [ripe.net #1133019] Re: Your RIPE Atlas Probe is not connected to our network

There's no firewall / ACL, anything on the way, just pure L3 device. Probe worked properly, then disconnected without any logical reason with that notification received. Probe is pingable on both IPv4 and IPv6 from outside, proper (so there's no L3 issue on the way). Probe itself resets all incoming TCP connections from my IP address located in another ASN (probably due to firewall at the probe). On traffic mirrored from the probe I see ocasional NTP queries to some servers, so "something" on probe runs. Nothing else. You do not provide any access to probe for hosts to check anything directly, so I expect you can manage fully (as this is something running any kind of Linux?). As probe has public IPv4/IPv6 address, you should not have problem reach it. Unfortunatelly, probe is located on remote datacenter with limited physical access. Also this is not a solution of problem - with reboot you probably loose anything to diagnose causes of this problem. What checks did you performed at your side before sending such email? You don't have any kind of "emenergency" probe management, like SSH shell access directly to the device? What do you see in *your* logs about affected probe before it was disconnected?

probe selection criteria on "WW" measurements
by Paul Vlaar 25 Jul '14

25 Jul '14

Hi, I have two questions regarding probe selection for UDMs. When I specify for example that I want to run an ongoing measurement on 250 probes in the "WW" region, will these probes remain the same throughout the lifecycle of the measurement (unlimited) or will these be somehow randomized every time the measurement is run? Secondly, I am wondering about even spread of probe location in doing such a measurement. For instance I am as much interested in results from regions that have only a few probes, as I am interested in results from those regions that are better served. When I look at the results so far of a test measurement, it appears that I'm receiving results from 35 probes in US, but only 3 from FI and none from NO. The latter surprises me a bit since there are 100 probes reported in NO, so why aren't there any results from those coming back? While I understand that countries with more probes will likely yield more results, I am wondering if there is any method to get a better "country-balanced" result for measurements ran in "WW".

Support RIPE Atlas with RIPE NCC Board
by Daniel Karrenberg 25 Jul '14

25 Jul '14

The RIPE NCC Executive Board is discussing RIPE Atlas as documented in the latest meeting minutes that have been published recently. https://www.ripe.net/lir-services/ncc/executive-board/minutes/2014/minutes-… The relevant part is: --------- 3.3.1 ATLAS EB286 01/04/2014 AP The Board asked Axel to produce a break down of the costs for ATLAS over a period of  3 years and an outlook beyond 2014 to see the development on OPEX and CAPEX in the coming years. Furthermore the Board asked to see a comparison between the current figures and a case where TTM and DNSMON services were continued in their current form in 2014 and beyond. Status 19/06/2014: DONE There was discussion about the value of ATLAS to the various stakeholders and the associated maintenance cost. After discussion the Board asked for clear documentation of the results of the activities so that they could review and ultimately justify the cost of the project overall. The Board discussed the ongoing cost of the ATLAS project. The Board agreed that the value of the project needed to be packaged correctly. ATLAS now has many other projects wrapped into it and the activity needed proper and concise documentation as well as a solid marketing plan moving forward. ACTION EB295: The Board asked Axel to produce a value proposition for the ATLAS service in preparation for the September meeting. --------- It looks to me that the board needs to be re-assured that RIPE Atlas is valuable enough for the membership to justify the cost. Between the lines I read basic support but a desire to hear a consistent story and success stories of benefit to the membership. Of course the RIPE NCC staff will produce an answer to the board and I will do my best to help with that. But ultimately the board is responsible to the membership. So it would be very very helpful if we could get some users of RIPE Atlas to speak up both directly to the board and to help us prepare our answer to the board. Daniel

some thoughts and question regrding probe "stability"
by Wilfried Woeber 22 Jul '14

22 Jul '14

Hi Folks, triggered by the discussion related to DNSMON, and an issue (power, resolved) with one of my V1 probes, I'd like to get some input or start a disussion or an investigation. To start with, I am not very clear what the term "stability" w/should mean in this context, as the probes are supposed to buffer measurment data locally, at least for a while (true?). So, here goes... Obviously, looking at some Atlas Stat pages, there are probes with a 100% uptime. Now, looking a the 3 under my supervision (2x V1, 1 Anchor), ref "Connected" and "Disconnected", there's no chance to get near that value, as all of them tend to topple over on a regular basis, mostly for a *short* period of time in the range of 0m(!) to some 30+m. With respct to the bahaviour of the Anchor, which is mounted in the same rack as the backbone router it connects to, in a Data Center, we tried to correlate the (reported) disconnection events with the router and interface logs for the probe. No luck there, also, no maint works or the like, so I presume the Anchor didn't reboot or that there were "real" network problems. Let's compare the most recent dis/connection logs for my 3 pets: ID 6009 2014-07-14 03:58:03 3d 8h 16m Still Connected 2014-05-27 03:03:54 48d 0h 46m 2014-07-14 03:50:47 0h 7m 2014-05-20 15:19:02 6d 11h 37m 2014-05-27 02:57:00 0h 6m 2014-05-14 21:16:56 5d 17h 59m 2014-05-20 15:16:22 0h 2m 2014-04-08 16:03:21 36d 5h 1m 2014-05-14 21:05:17 0h 11m ID 0466 2014-07-13 23:31:05 3d 12h 45m Still Connected 2014-07-09 23:05:40 3d 23h 54m 2014-07-13 22:59:49 0h 31m 2014-06-16 10:53:21 23d 11h 55m 2014-07-09 22:49:04 0h 16m 2014-05-25 09:03:06 22d 1h 38m 2014-06-16 10:42:00 0h 11m 2014-05-24 20:34:50 11h 54m 2014-05-25 08:29:12 0h 33m ID 0414 2014-07-07 23:41:23 9d 12h 35m Still Connected 2014-07-02 03:58:45 5d 19h 31m 2014-07-07 23:29:54 0h 11m 2014-06-13 09:37:50 18d 18h 7m 2014-07-02 03:45:08 0h 13m 2014-06-08 13:22:14 4d 20h 7m 2014-06-13 09:29:38 0h 8m 2014-05-21 08:29:23 18d 4h 45m 2014-06-08 13:15:11 0h 7m Again, I fail to see some obvious correlation, what am I missing? Does anyone else see a similar pattern? How to start debugging, if there's anythig that needs debugging? Thanks for your ideas and help! Wilfried

Actual public measurements
by Brian Rak 22 Jul '14

22 Jul '14

Is there any way to link someone to a public measurement, without requiring that they go and sign up for a RIPE account? It's an annoying extra step when I'm just trying to show someone the results of a measurement. I'm aware I could grab that raw data via the API, but then I'd have to re-implement the UI... which I don't have time for.

Questions about paris traceroute
by Thomas Holterbach 18 Jul '14

18 Jul '14

Hi all, I would like to start some Paris-traceroute measurements from RIPE Atlas probes, with a specific frequency and a control over the paris id. In particular, I am wondering if it is possible to start a traceroute measurement with all the 16 paris id at the same time. Because so far, I only find out how to start periodically a traceroute with a different paris id. I am also a little bit confused about the interval between two measurements. In the doc, it is written that the default value (900s) is the minimum, but when I create a UDM, the minimum interval seems to be 60s. I also tried 10 secondes with Restful API and the measurement started, but the real interval seems to be far upper than 10s. Can you give me more informations about this interval ? Thank you for your help, Thomas.

adding probes to UDM
by Jared Mauch 17 Jul '14

17 Jul '14

I have a few ongoing UDMs and there’s a few things that have occurred over the duration: 1) I requested 5 probes and only 3 were available (at the time). Is there a way to request the system consider more? 2) I requested 5 probes and 5 were available, but some have fallen out (and are now crossed out). I want to request 1 or 2 more to get back to the 5 threshold so I feel I have more accurate data. Are either of these possible, or do I need to stop these and create a new UDM with a larger number of probes to keep a more stable population over time? (They have been running for ~2 months so far). - jared
