Probe down - USB?
by İhsan Doğan 13 Aug '16

13 Aug '16

Hi, My probe went down this morning. Probably I'm running into the issue with the USB stick. I was thinking to replace the USB stick. Are there any special requirements (size, speed, etc.) for the USB stick? -Ihsan -- ihsan(a)dogan.ch http://blog.dogan.ch/

Dear colleagues, We've decided to support "IPv4-only" anchors in ASNs where IPv6 is not available. You can learn more in this RIPE Labs article: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ipv4-only-ripe-atlas-an… Regards, Robert Kisteleki RIPE NCC

Awarding credits for measurement results
by Robert Kisteleki 04 Aug '16

04 Aug '16

Dear probe and anchor hosts, When you create measurement results in RIPE Atlas, you’ll now get a little something extra back in the form of credits. From now on, we’re giving all RIPE Atlas probe and anchor hosts one credit back for every measurement result they generate. This means that most probe hosts will earn up to an additional 10,000 credits (50%) per day on top of the credits they get for keeping their probes online, anchor hosts will earn an additional roughly 200,000 credits (100%) daily, and DNSMON anchor hosts will receive roughly 1,000,000 additional credits. This is our way of rewarding the probe and anchor hosts who contribute the most to RIPE Atlas - enjoy! Regards, Robert Kisteleki RIPE NCC

Probe reported as disconnected but is actually online
by Boris Fersing 04 Aug '16

04 Aug '16

Hi there, Today I had a power failure at home and since then, my probe's state is "disconnected", but I checked the network traffic and it looks like the probe is actually able to reach the internet and is doing some DNS requests I don't know about: U431.M<PROBES MAC>.sos.atlas.ripe.net U980.M<PROBES MAC>.sos.atlas.ripe.net U116.M<PROBES MAC>.sos.atlas.ripe.net Do you know what those SOS requests mean? The SOS history on the atlas.ripe.net page doesn't show any useful message. The Status (beta) tab shows the following message: ===== Firewall Problems Suspected What does this mean? Probes connect to the controlling infrastructure using SSH (via port 443). If our system detects that the probe is successfully engaged in other kinds of activities, but these SSH connections fail, then it's highly likely that these connections are somehow blocked or disturbed. This could be because there's a firewall blocking these connections. Another reason could be that there is a (transparent) proxy in the way that affects port 443 (usually HTTPS) connections, which means the probe and its controller cannot mutually authenticate each other (because the proxy is interfering). How can I fix this? Check whether you have a firewall or an aggressive NAT appliance preventing such connections. Also check whether there's a transparent proxy on the path. Alternatively, you can try plugging in the probe on a different network to confirm whether a firewall / proxy is really causing the problem. ===== But since I don't know which host the probe is trying to connect to, I can't really test it and tcpdump doesn't show any attempt to a port 443. Thanks Boris

Hi all, We are currently experiencing an issue with the load balancer of the streaming service over SSL. We are working on it. The service on http on port 80 is not affected. The Atlas CLI and Cousteau are not affected too. Sorry for the inconvenience. It will be fixed soon. Best regards, Massimo Candela

New analysis of version 3 probes on RIPE Labs
by Philip Homburg 02 Aug '16

02 Aug '16

Hi, As promised, we’ve continued to look into the issue that some people are having with the version 3 probes and have found that actual hardware failures for version 3 probes are in fact relatively rare compared to filesystem corruption. We’ve published a new article on RIPE Labs with the complete analysis: https://labs.ripe.net/Members/philip_homburg/further-analysis-of-ripe-atlas… We’ll continue looking into these issues, so stay tuned for future articles.
