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

atlas-stream SSL problem
by Massimo Candela 03 Aug '16

03 Aug '16

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.

Re: [atlas] Troubleshooting USB stick issues - reaching out

Hi, It's not just the Sandisk sticks that go into permanent readonly mode. The Verbatim have the same problem. Mine went into readonly mode after only 10.5 months of service.

Identifying widespread outages using atlas?
by Rafal.Jankowski＠thomsonreuters.com 20 Jul '16

20 Jul '16

Hi I'm wondering if there is any good statistic tool that helps identyfing any widespread Internet outages using ripe atlas probes such as ISP issues (like todays http://www.bbc.co.uk/news/technology-36844712), cable cuts, etc. Normally I select probe and look into public measurements but it does not seem to be very effective. ________________________________ This e-mail is for the sole use of the intended recipient and contains information that may be privileged and/or confidential.

Stop time not retained when creating new measurement
by Bill Fenner 18 Jul '16

18 Jul '16

Hi, I created a new measurement this morning, https://atlas.ripe.net/measurements/4467029/ . Its status says: Timing 2016-07-16 07:35 No stop time defined but I filled in the stop time when I created the measurement via the web page; I saved the command that it gave me to invoke the API and it includes: ... "is_oneoff": false, "bill_to": "fenner(a)fenron.com", "stop_time": 1469361631 } a) this feels like a bug. Is it a bug? b) can I add the stop time post-facto, or should I remember to go back and click "stop"? Thanks, Bill

start one-off from probe overview page
by Job Snijders 15 Jul '16

15 Jul '16

Hi all, UI feature requests: It would be cool if there is a button to start a one-off measurement from a certain probe's overview pages. If I am at https://atlas.ripe.net/probes/25606/ - would be nice if I can immediately jump into a one-off, rather then copy-pasting the probe's ID and creating a new one-off UDM. Kind regards, Job

Error creating one-off ping measurement
by Jared Mauch 15 Jul '16

15 Jul '16

We are attempting to test some things and I’m getting this error. "A one-off measurement cannot have the interval field set” It seems to be a problem if this field is even blank, anyone else experience this? - Jared
