Protocol/Technology testing?
by Daniel AJ Sokolov 15 Feb '12

15 Feb '12

Hello, Are there any plans to extend the Atlas probe's functionality from simple Pings to more sophisticated testing? For example: Can actual payloads be transferred (http, ftp, SMTP, NNTP etc.) and with which parameters? Is encryption available (https, ssh, starttls, etc.)? Some countries and/or ISPs restrict what users can do. Currently, Iran is inhibiting all encrypted international connection. For the users on the ground this is horrible - no gmail, no yahoo, no online banking, no Tor network - no proivacy! Yet on the Atlas network everything seems to be fine, as pings still work. (However, only one of the six probes is online, the rest has been offline for weeks. And the one that is online was offline for weeks until a few days ago. I'm not sure what the issue is there.) It would be good to know if some protocols are not available in a certain jurisdiction. Of course, such tests could be done at a much lower rate than Pings - some maybe every hour, others every couple of hours. Then again, the probes might not be mighty enough?

Probe DNS entry A more useful than AAAA for dynamic IP hosts
by Software Registrations 14 Feb '12

14 Feb '12

Hello everybody, I have just received and put in service my probe. This is my first post to the list (I have been monitoring the traffic for a while: none). I wish to take the chance to admire the design and compact packaging ! Great work! Back on topic, for us low-lies with dynamic IP addresses using the probe DNS entry (maybe with a CNAME entry) could be a great way to ensure our Dynamic DNS entries are up to date and our network could be reached from remote. I am running a full IPv6 network receiving a /48 from Hurricane Electric and the probe tend to select (at least in my short experience) the autoconfigure (from MAC) IPv6 address as its Internet Address to use in the DNS record: fabio@atlantic:~$ host -t A pdxxxxx.probes.atlas.ripe.net pd456a699.probes.atlas.ripe.net has no A record fabio@atlantic:~$ host -t AAAA pdxxxxx.probes.atlas.ripe.net pd456a699.probes.atlas.ripe.net has IPv6 address 2001:470:xxxx:2:220:4aff:fee0:xxxx fabio@atlantic:~$ I saw that there are plans (in the FAQ) to add support both for AAAA and A records at the same time but I believe it would be beneficial for users to be able to select which record is generated or have the A record as default while waiting for the support for both to be implemented. Thanks for listening. Fabio

06 Feb '12

Hello, For our purposes, we use RRD image generator and get plots from the different probes. We used the recommendations that described on this page: http://atlas.ripe.net/doc/api . We found, that this information is not actual. So we would like to suggest you to update it: • probe ID < 500: zpm01.atlas.ripe.net. • probe ID >= 500 and probe ID < 1000: zpm02.atlas.ripe.net. • probe ID >= 1000 and probe ID < 2000: zpm03.atlas.ripe.net. • probe ID >= 2000 and probe ID < 3000: zpm04.atlas.ripe.net. In addition, it would be nice if the page with the documentation will contain more extensive and detailed information about the API. -- Thanks in advance & Best Regards -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Pavel Veselovskiy Email: pavelveselovskiy(a)gmail.com Phone: +7 927 686 12 32

Possible issue with DNS/tests getting stuck?
by Kyriacos Sakkas 27 Jan '12

27 Jan '12

Dear all, I have a statically configured probe, FW version 4270. If the internet connection goes down/flaps the probe seems to get confused and stops communicating (is shown as Down) even when the connection is back up and stable, but can actually be pinged etc from inside and outside my network fine. I have a second probe that is on DHCP (FW 4280) on a different network, this one seems not to have the same issue, don't know which is the important differentiator. Wondering if anyone has similar issues and a solution other than switch it off and on again. Thanks to All, Kyriacos

Survey results on Atlas open-sourcing
by Richard L. Barnes 05 Jan '12

05 Jan '12

The brief survey I put out a couple weeks ago has gotten 34 responses. The response rate seems to be tailing off, so I've closed the survey. Here's a summary of results. First, the simple things: -- All but one respondent is an Atlas probe host. -- Respondents preferred source to binary release 26:4 (4 abstentions) The responses as to reasons for wanting the Atlas platform opened up are a little more challenging to read. There were four options that respondents, from which respondents could choose as many as they wanted. 0 - I'm not interested in RIPE NCC releasing the Atlas firmware 1 - So that parties other than RIPE to build probes that can feed into the Atlas system 2 - So that I can easily build Atlas-like probes for my own, independent measurement network 3 - So that I can re-use some Atlas features for a non-measurement-related purpose The response patterns, ordered by frequency Pattern Frequency 1 8 2+3 6 0 5 1+2 3 1+2+3 3 2 3 3 1 (who noted: "I don't care too much") Respondents could also fill in an "other" response for their reason. There were two major themes to these responses: -- Security, in the sense both of making the device more secure, and of assuring probe hosts of what the device is doing -- Contributions, i.e., that the community could contribute to probe development One respondent also noted in an "other" response that responses 1 and 2 are not necessarily mutually exclusive; a modified probe could feed both the RIPE system and a private system. Analyze as you will :) --Richard

Probe location

Hi, what's the method to set the probe location? When I set up my probe, I locate it in the nearest subway station (of course, is not there), but now in the map the probe is too near of my home. The probe location is moved about 300 meters. Are you using other method to locate the probe (IP addresses, Google wifi map,...)?

New measurement target suggestion: 6to4 anycast
by Roman Mamedov 21 Dec '11

Hello, I'd like to suggest adding to the list of monitored addresses a new one: 192.88.99.1 - 6to4 anycast IPv4 to IPv6 gateway; https://en.wikipedia.org/wiki/6to4 https://tools.ietf.org/html/rfc3068 This could provide interesting data on what percentage of networks have this address blocked/inaccessible (resulting in broken operation of 6to4), and also what is the average latency to the closest 6to4 gateway across various countries/regions. The next step would possibly be the collection of statistics which ASes 'see' whose 6to4 gateways, this can be inferred from the AS of the traceroute hop that is right before the 192.88.99.1 on the trace. -- With respect, Roman ~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Stallman had a printer, with code he could not see.

Algortithm for probe detecting its offline
by Greg B - NANOG 20 Dec '11

20 Dec '11

Hi, I wanted to ask what is the algorithm / methodology used for a probe detecting / reporting it is offline? I ask, because this morning I intentionally rebooted my cable modem on the network the probe is attached to, which brought my internet down for about 1-2 minutes (I was using the internet immediately after the cable modem re-synched), but the probe is reporting that outage as a 29 minute outage rather than a few minutes. Any comments on why there should be such a large variance from my actual experience versus what the probe saw? -Greg

New: Atlas resource coverage (and more maps!) beta
by Robert Kisteleki 16 Dec '11

16 Dec '11

Dear Atlas Users, Today we enabled another interesting feature (in beta mode, for now): details about what networks Atlas covers at the moment. This feature lists IPv4/IPv6 prefixes, ASNs and countries. This information will also be used for User Defined Measurements, in order to filter vantage points to specific networks or locations. You can access this at https://atlas.ripe.net/atlas/coverage.html Background information: * the prefixes and ASNs are looked up in RIS, based on the address of the probe * the country code is looked up in OpenStreetMaps based on the probe geolocation We are aware that in some cases the lookup has a surprising result. One example is 6to4: for IPv6 related ASNs the prefix is 2002::/16 but the ASN can be misleading. We'll most likely stop looking up ASNs for 6to4 (and Teredo) prefixes. If you see anomalies *not* related to this, you can let us know at atlas-dev(a)ripe.net Regards, Robert, for the whole team

Re: [atlas] Email or SMS alert when probe goes offline/online
by Greg B - NANOG 15 Dec '11

15 Dec '11

Hi, I see there was a thread started back on September 7, 2011 with subject: Email or SMS alert when probe goes offline/online this was prior to me joining the mailing list. I'd like to voice my support for a user-configurable amount of time for the Atlas system to send out an email notification that your probe is down (and returned to service). My probe which I run on my home internet connection was apparently down for 3.5 days before I just happened to login to look at the stats. Considering I was at home for much of these 3.5 days, and my Internet connection was working, I assume the probe crashed because simply power-cycling it "fixed" the problem. I know that if I got an email ~15 minutes after the probe was down, my probes downtime would probably have been closer to about 30 minutes rather than 3.5 days. Thanks. -Greg

problems with (links to) stat.ripe.net
by Wilfried Woeber, UniVie/ACOnet 28 Nov '11

28 Nov '11

Just wanted to double-check... Are you aware of problems - or do others see similar effects - with the display of pages that are linked to from the Atlas panels? IE7 (on XP) complains with "error on page" and Iceweasel on Debian does not complain, but doesn't display any useful information either. As an aside, with Iceweasel the "Result Boxes" rectangle seems to be pinned to a fixed place on the screen and obstructs the information when the page is scrolled underneath. Just wanted to raise a small flag before doing screenshots and other investigations. Thanks for listening, Wilfried.

Outage on one UI server
by Robert Kisteleki 11 Nov '11

11 Nov '11

Dear All, One of our UI servers is down at the moment. We've been trying hard to restore it for some hours now, but there's a chance that we'll not succeed before next week. The result is that for a subset of the probes we're currently not generating RRD graphs. The affected probes are ID<=500 and ID>=2000. We do not expect data loss, as all results are stored on intermediary nodes, however you'll not see these results until the issue is fixed.

follow-up on private discussion regarding management of access to probe measurement data
by Wilfried Woeber, UniVie/ACOnet 02 Nov '11

02 Nov '11

Hi Vesna, Team, here is my reminder regarding the suggested "better" granularity to manage the access to measurement data per probe. As I see it right now (please feel free to correct me!): - right now there is an "individual" guardianship per probe(s), this guardianship includes configuration access. - regarding access to the measurement data, the guardian only has two option to manage the access privileges - private and public, or simply put: white or black. Now, given that different persons are managing different probes, if I want to grant access for them, or apply for access to the data of probes under their control, the only way to accommodate this is to declare the probe(s) involved "public". That is not necessarily what we want. Thus I am asking for a sort of "intermediate" or "group" access category. I can see a couple of ways to help with this, for example by providing a way to add other user identities to be authorized for (non-config, i.e. read-only) access. An alternate approach could be to allow creation of Groups, into which some probes could be put and which user identities could be added to for access to the probes in the group. Of course any other approach would be equally fine with me, I just tried to come up with a least one idea instead of only asking for added functionality :-) Btw, my feeling is that such a facility would be even more useful in support for the upcoming UDM stuff! Thanks for reading as far, Wilfried.

3d downtime reported - why?
by Daniel AJ Sokolov (lists) 02 Nov '11

Hello, I have noticed that my probe data on the atlas.ripe.net-website reports at downtime of over 3 days: 2011-10-25 04:17:20 UTC to 2011-10-28 08:04:53 UTC. In fact, my connection was not down - maybe a few minutes (that seems to happen regularly), but everythin longer we would have noticed. We use this internet connection most of the day. My probe ID is not unter 500 but over 1000. Is this an error in the database, a problem with the reporting system or any other known bug? Did anyone else experience something like this? Or is there some issue I can resolve locally? Thank you Daniel AJ -- My twitter feed: @newstik http://twitter.com/newstik

Probes, static network configuration and upcoming firmware
by Robert Kisteleki 10 Oct '11

10 Oct '11

Dear Atlas hosts, We're about to release a new firmware version that supports more built-in measurements as well as prepares the probes for the User Defined Measurements feature. We have recently discovered that there's a compatibility issue with the upcoming firmware and (non-DHCP) static network configuration. In order to avoid problems that would come up in this case, we have temporarily disabled the static network configuration panel. We are in the process of releasing a corrected firmware, and enable static configuration for this version automatically. For the probes that already have static configuration up and running: there's nothing you need to do, we'll make sure that during the upgrade these probes keep their static network configuration. We apologise for the inconvenience this may cause. Regards, Robert

New Face(s) in the Measurements and Tools Area
by Daniel Karrenberg 07 Sep '11

Gentlepeople, I am very happy to announce that we have a new community builder for measuremnts and tools: Vesna Manjolovic. Many of you will know Vesna already as a trainer and through her very enthousiastic work on our IPv6 promotion and IPv6 related measurements. Vesna has been with the RIPE NCC for more than 10 years; it gives me great pleasure to promote her to a position that makes optimal use of her capabilities and ambitions. Vesna's first priorities will be to establish relationships with current and potential sponsors of RIPE Atlas and to help develop a plan for the evoloution of RIPE TTM. RIPE Atlas sponsors and RIPE TTM customers will hear from her soon. The decision to hire internally not only affirms that initiative and effort are rewarded at the RIPE NCC; it also provides the budgetary room to engage another person to help with the community building for measurements: Ann Barcomb will therefore join Vesna in October. >From that time both Vesna and Ann will start to work on additional goals such as building a strong community around RIPEstat. Please join me in welcoming Vesna and help her to achieve her goals, which are also our common goals. Daniel

Doing this monitoring-style is not a job for the NCC, IMHO, as this certainly involves way more work that one might think at first. This is a case for your local monitoring solution, which does that job much better. That being said, it might make sense to e-mail hosts if a probe has been down for a *long* time (something like "one e-mail per week of downtime"), just to catch dead hosts and unnoticed configuration fails. - D.

Increased network uptime . Greater availability of the RIPE Atlas Probe (and thus increased data gathering). Anyway, this is something that I'd like to see - email alerts at a minimum. Robert

[atlas]Apache again....
by Viktor Naoumov 30 Aug '11

30 Aug '11

Back to apache... 'Listen 8080' was a bad solution because it opens apache to the world. Instead we should do now: Listen 127.0.0.1:8080 #Listen localhost:8080 Having Listen localhost:8080 <VirtualHost *:8080> prevents apache from starting with the following message: zelenka-dev:/etc/apache2# /etc/init.d/apache2 restart Restarting web server: apache2 ... waiting (98)Address already in use: make_sock: could not bind to address 127.0.0.1:8080 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. failed! looks like it because zelenka-dev:/etc/apache2# host localhost localhost has address 127.0.0.1 localhost has IPv6 address ::1 but not sure yet.... didn't have time to figure out what do you think? /vty

It looks like th UI for the "My Probes" section is broken again for IE7. All the other sections of the site seem to work. Wilfried.

[atlas]Probe with static IPv6 can 'lock up' if unreachable on IPv6
by Kenneth Aalberg 11 Jul '11

11 Jul '11

Greetings. As advised by other members of the list, I've moved my probe from behind a router that provided IPv6 tunneling and to the pure IPv4 network. However, when reconfiguring the probe, the static IPv6 address I added to it seems to not 'let go'. It now gets an IPv4 address as it should, but it shows as down in the probe list. The configuration page also claims it still has the static IPv6 address configured. I mentioned earlier about fallback to IPv4, but I'd also like to extend the question towards whether there is any functionality that lets the probe try 'last ditch efforts' to connect in cases where its configuration just doesn't work? (As in, give up on static addresses and try DHCP even if it has been assigned a static address) Best regards, Kenneth Aalberg

[atlas]Falling back to IPv4 if IPv6 connectivity is lost?
by Kenneth Aalberg 11 Jul '11

11 Jul '11

Greetings, Probers. (Yes, that was the first name that came to mind. :P ) I've joined the probecloud, and it is working fine. However, I am on an IPv6 tunnel behind a NAT that doesn't let me configure protocol 41 to be forwarded to one specific host (my linux router). Thus, the AYIYA tunnel is in a NAT table as a normal connection, and will sometimes be cycled out if it is the oldest connection and a new one is attempted, regardless of whether the NAT entry has seen traffic recently or not. The probe receives an IPv6 address, and uses this correctly. However, if the tunnel should go down, the probe will also be marked as down, even if it is actually still alive and can communicate through IPv4. Is there any kind of fallback option to try IPv4 connections before declaring a probe host down? Or would it make more sense for me to disable IPv6 on the probe to ensure it accurately represents the actual state of my connectivity? Best regards, Kenneth Aalberg Probe 737.

[atlas]Probe rebooting every minute
by Roman Mamedov 09 Jul '11

09 Jul '11

Hello, Probe ID 73, it seems to reboot itself after about 1-2 minutes of operation, even though according to tcpdump on the gateway it can successfully communicate with the control DNS, NTP, server, can ping stuff and does receive ping replies. What could be the problem? -- With respect, Roman

[atlas]'Location' sorting for the Public Probes
by Carsten Schiefner 04 Jul '11

04 Jul '11

Hi there, not sure sure whether that's been raised already - but the strictly alphabetical ordering of the probes when 'Location' sorting is activated, doesn't make any reals sense to me; cf. the attached screen shot. Maybe a somewhat greater "intelligence" could be deployed here? I'd suggest the DNS approach: from right to left. :-) Cheers, Carsten -- Homer Simpson meint: http://www.youtube.com/watch?v=Fk0To_o6NxE

[atlas]Atlas probe is "never seen"
by Martin Topholm 02 Jul '11

02 Jul '11

Hi all, I connected the Atlas probe thursday and is is conducting measurements as seen with tcpdump and from the logs on the Atlas site. However the site says the probe is "never seen". How long will it take for the site to register with the probe? Should I reset the probe? Probe ID 776 (near Helsinge, Denmark) -- Best regards, Martin Topholm
