OT(?) SamKnows/EC Test Project
by Wilfried Woeber, UniVie/ACOnet 21 Feb '12

21 Feb '12

Maybe this is a tad off-topic, but maybe not... Has anyone been able to get in touch with a human being (over eMail) regarding the participation in their measurement project? Any and all of my attempts till now failed miserably, they just keep sending me reminders to accept their fine print; and I am just about to pull out/unsubscribe. Any input or advice gratefully accepted. Best regards, Wilfried.

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

Tweaking RRDs for built-in measurements UPDATE
by Pavel V. Veselovskiy 06 Feb '12

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
by Rodolfo kix Garcia 29 Dec '11

29 Dec '11

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

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 21 Dec '11

21 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.

no gateway for IPv6
by Wilfried Woeber, UniVie/ACOnet 24 Nov '11

24 Nov '11

Hi folks, just noticed that for an IPv6-capable probe no gateway info/address is given. Curiousity - is there an "good reason" for that behaviour or is it just not implemented yet? Lowest prio, of course :-) Wilfried.

More maps available
by Robert Kisteleki 22 Nov '11

22 Nov '11

Dear Atlas Users, Today we've enabled the "DNS root anycast instance map" that was announced at the RIPE meeting and in the RIPE Labs article here: https://labs.ripe.net/Members/kistel/new-ripe-atlas-features-in-the-making Clicking on the "Maps" link in the menu bar (top right) leads you to a page that lists all maps we have available at the moment, including the anycast map. As a small enhancement we also begun to link AS and prefix information to RIPEstat, to facilitate looking up more information about these resources. This is visible on the "my probes" page as well as on various maps (when clicking on individual probes). Regards, Robert (for the whole team)

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. Please accept our apologies for the inconvenience this may cause. Regards, Robert Kisteleki

packet loss seen by probes to labs.ripe.net?
by Wilfried Woeber, UniVie/ACOnet 06 Nov '11

06 Nov '11

Dear Atlas Team, it looks like many (or even most/all?) of the probes seem to "seen" an increasing rate of packet loss to destination labs.ripe.net (on IPv4). The problem(?) seems to have started around Week 41 and gets worse since. Could the Atlas Team have a look at that? Thanks, Wilfried.

Hi, Would it be possible to make some tagging functionality on the web page due to reasons as downtime etc.? For me it would be nice due to maintenance or similar.

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.
