Unknown probe ID for v2 probe
by Stefan Jakob 08 Jun '16

08 Jun '16

Dear RIPE Atlas Probe Team, Today I wanted to register my probe, but I can not figure out the probe ID. This probe is a v2 probe with MAC 00:20:4A:E0:21:2C The Probe is connected and should be visible behind: 130.180.54.46 (sbh12.dy.n-jakob.eu) My DHCP isn't showing the probe ID as name. Just shows * or empty hostname. Inside my RFC1918 address space it has the IP 192.168.2.101 and is reachable via ICMP at least. Do you guys see the probe connected to your infrastructure? Can you provide the ID, so that I can finish the registration? Rgds, Stefan Jakob

Update on problem with probes’ USB sticks
by Andreas Strikos 25 May '16

25 May '16

Hi all, We want to let you know that we have seen the active conversations about the USB sticks and the problems they’re causing for some RIPE Atlas probes. We are aware of these issues, and are taking steps to ensure this doesn’t become a real problem for the RIPE Atlas system. We’ve just published a RIPE Labs article that explains the preliminary analysis of our logs we’ve begun to investigate this issue. In the coming weeks, we will make sure we analyse all the logs we have in order to try to find a possible solution. We will keep you posted with any updates we have through this article. https://labs.ripe.net/Members/philip_homburg/a-visual-impression-of-probe-l… We apologise for the inconvenience this is causing for some of our users. Thank you for continuing to be a part of RIPE Atlas. Regards, Andreas Strikos (on behalf of the RIPE Atlas team)

v4 versus v6 -- who connects faster?
by Bajpai, Vaibhav 24 May '16

24 May '16

Hello, -- sorry for cross-posting Here [a] is a toy v6 service I came up with during the RIPE Atlas hackathon over this weekend. Thought I share this along: [a] http://goo.gl/hbzbwD You enter a dual-stacked website (ALEXA top 10K) and it shows you the difference in TCP connect times over v4 and v6 as seen by all dual-stacked RIPE Atlas probes (~1.3K probes). You can also filter the visualisation from a specific origin-AS. This additional filter can be useful to view performance towards a website from a specific origin-AS (say DTAG). Disclaimer: This is an outcome of a 1.5d long hackathon project. As such, the codebase is possibly inundated with bugs. Please don’t see it as a production service :-) Best, Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com Room 91, Research I School of Engineering and Sciences Jacobs University Bremen, Germany ===================================

USB drive more harmful than helpful?
by Michael Ionescu 24 May '16

24 May '16

>From both my own (short term) experience and from what's being written on this list, I'm getting the impression that the USB drive may be costing more than it's worth. I have in only about 3 months experienced multiple probe issues due to USB drives and there have been multiple threads on this list which suggest that I am far from alone. I will go so far as to suspect that a substantial number of disconnected and abandoned probes have similar issues, but the hosters may be unwilling or unable to spend the necessary time to investigate and resolve them. If the main reason for the drive is to cache data during unavailability of the command and control center, this may not be worth the effort. I would suggest making the drive optional. That may mean fewer data points from and/or fewer UDMs possible on those probes without a functioning drive. But it may also mean a couple thousand probes more connected and therefore available for measurements at all. I'm not saying that probes should not ask for their drives to be fixed/replaced, but it should not be a requirement for the probe to run. One might give an incentive to hosters to run their probes with functioning drives by giving less credits for connected probes without a drive. Any thoughts? Michael -- Sent from a mobile.

New on RIPE Labs: New RIPE Atlas APIs and User Manuals
by Mirjam Kühne 23 May '16

23 May '16

Dear colleagues, We've updated the RIPE Atlas APIs - and there's a comprehensive new manual to explain how to use them. As a result, the current (version 1) APIs are still available for now, but will be deprecated by the end of the year. Please find more information on RIPE Labs: https://labs.ripe.net/Members/suzanne_taylor_muzzin/new-ripe-atlas-apis?pk_… Kind regards, Mirjam Kuehne RIPE NCC Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

It was powered through the dedicated wall plug included with the probe. On May 22, 2016 12:03:39 AM GMT+02:00, Phillip Remaker <remaker(a)gmail.com> wrote: >How was the drive powered?

Could you perhaps write some statistical data regarding drive usage to a cleartext partition that could be evaluated by the hoster once the probe is in limbo? --

Re: [atlas] USB drive issues
by Geert Jan de Groot 21 May '16

At the first hint of trouble, it may actually have been premature, I swapped the USB drive on my probe with a brandname replacement. Note that there is a lot of poor quality stuff, especially in "giveaway" drives, and the fact that the disc is encrypted of course does not help heuristics in the USB drive controller to lengthen the drive life. The replacement was painless: power down, insert blank disk, powerup, did the dishes, when I was done the probe was done initializing and everything was working fine. I've added "replaced-broken-sandisk-usb-stick" to the probe. Perhaps this is a useful heuristic to monitor how prevalent the problem really is. Geert Jan
