accounting glitch for probe 15105
by Kasper Pedersen 28 Jun '16

28 Jun '16

Tonight Freddy Bulow's post made me take a look at 15105. I was certain it would be up, but that was only halfway what I found. It was listed as being down since June 16th, and the uptime graph was showing an 8-day hole. It was, however, showing traffic on the graph, and locally I was also seeing normal probe traffic. Here's a pcap: https://highlyexperimental.kitsune.dk/201606242131.pcap At packet 765 I powercycled the probe, it came back up, and now showed 0 minutes up. That was expected, but what also happened was that the uptime graph filled in to no longer show downtime, the log entry showing the probe going down on the 16th disappeared (yes, really), and a new one showed it going down on the 24th with a few seconds downtime. The only thing left is the 8-day hole in the credit log, that did not change. /Kasper Pedersen Beware of corner cases. They tend to have sharp corners.

How to get a new USB stick ?
by Élodie de FranceServ Hébergement 27 Jun '16

27 Jun '16

Hello, The SanDisk USB (4GB) provided with the RIPE Atlas probe don’t work anymore since more 5 days and the connection logs say “NO USB”. To check the USB stick, I plugged a personal one and since this time the probe is working again. I have this probe number 18685 since 2015-03-05. I would like know if the team could send me a new USB stick to replace the old one please or if I need to buy a new one myself ? Best regards, Élodie

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.

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

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

Re: [atlas] Probe is down but does send DNS according tot SOS history
by gboonie 21 May '16

21 May '16

No. Everything seemed normal except that it was down. All tags like "IPv4 works" etc. were there. The only thing was that the status was down. So I pulled the power, pulled USB, replaced the power. Went to brush my teeth and came back to replace USB and went to bed around 23:30 (21:30UTC) A few hours (!) later the probe came back to live. The power for the probe comes from the modem. That might be a possible cause, I'm thinking. Could the developers please see if the probe can indicate power shortage? Could it get some recovering mechanism built in?

Re: [atlas] USB drive more harmful than helpful?
by Joe Provo 20 May '16

20 May '16

Fwiw, I always power directly from an outlet, never tributary on the USB. I've yet to have such fails, so my anecdata aligns with the underpower theory. On May 20, 2016 15:08, "Phillip Remaker" <remaker(a)gmail.com> wrote: So I have a few theories. I have now had 3 different USB sticks fail on me: Two Sandisk 4GB SDCZ33 and one cheap generic 8GB replacement. The power draw of the TP-Link system + USB is probably more than the opportunistic USB ports they get plugged in to. An underpowered probe runs great MOST of the time, but a flash bit write is probably the highest power strain and Flash can get really unhappy with power interrupts, based on this SSD research: https://www.usenix.org/system/files/conference/fast13/fast13-final80.pdf I usually use a 500mA or 800mA supply, or tap a nearby router USB port in that range. I suspect the system may demand 1200mA or more. When most flash sticks get errored out enough, they permanently fail into a read only mode, or become fully unreadable. Read-only mode can be reset on some models, but it is not recommended by the vendor. At least one of the failed SANdisk units I had was stuck in a read-only mode. Also, probes may be subjected to ungraceful power down situations, depending on where they are stationed. That can also be a flash drive killer. I don't think we are hitting the write limits of the sticks. I suspect the units are often in underpowered or ungraceful pwoer-down situations, or the USB flash itself is not responding gracefully to poweroff situations. I don't suppose RIPE buys enough USB sticks to get to talk to engineers at SanDISK? I know the newer Raspberry Pi will report when it is in an underpowered situation. Can the TP-Link detect and warn when underpowered? What is the minimum power recommended for TP-Link + USB? Also, are there any USB sticks that have lower power needs and are more robust in low power IoT situations? Is anyone trying to post-mortem the failed sticks?

Probe is down but does send DNS according tot SOS history
by gboonie 20 May '16

20 May '16

Hi, How can it be that the status of a probe is down while I see current DNS requests in the SOS list without any remarks in the 'info' column? Even the power-up time is increasing. If the probe can send DNS requests, why does it not have some mechanism to recover? Seem not too hard to make it reboot if it's status is down. Thanks, Dave

New on RIPE Labs: There Is Gold in This Stream - Sifting Through Used RIPE Atlas Traceroute Results
by Mirjam Kühne 20 May '16

20 May '16

Dear colleagues, Please find a new article on RIPE Labs demonstrating the value of the results collected by RIPE Atlas independent of the original purpose for collecting them. Using all traceroute results from a particular day as an example, we first show that near real-time analysis of the result stream is feasible. Then we show that this has great potential for studying the packet layer of the Internet in general and for providing tools to network operators in particular. All this suggests a large and diverse potential for further work. https://labs.ripe.net/Members/dfk/there-is-gold-in-this-stream?pk_campaign=… Kind regards, Mirjam Kuehne RIPE NCC Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum
