RIPE Atlas Remote Learning session in September 2020
by Lia Hestina 31 Aug '20

31 Aug '20

Dear all, The RIPE NCC will organise a remote learning session for RIPE Atlas. Monitor your network and troubleshoot it with RIPE Atlas. Create specific tailor-made measurements that suit your exact needs using API calls or the command line interface. After this session, you will be able to: Monitor your network using RIPE Atlas measurements Troubleshoot your network using measurements from RIPE Atlas Use the RIPE Atlas command line interface and the API to create tailor-made measurements Pre-requisites: Basic knowledge of networks How the Internet works Basic knowledge of IP, ASN, domains Familiarity with pings and traceroutes Thursday, 17 September 2020, Timezone in UTC 08:00-10:00 <https://www.timeanddate.com/worldclock/converter.html?iso=20200917T080000&p…> Registration: RIPE NCC member, register here: https://lirportal.ripe.net/training/register/courseCode/MET20200006 <https://lirportal.ripe.net/training/register/courseCode/MET20200006> For non members please send an email with your name and email address to training(a)ripe.net <mailto:training@ripe.net> If you have any question about the event, please send email to training(a)ripe.net Kind regards, RIPE Atlas team _________

Re: [atlas] [RIPE-NCC/ripe-atlas-software-probe] Software probes only connect to one controller? (#45)

Those controllers are kept separate from controllers for hardware probes. We placed both controllers at Hetzner and unfortunately, Hetzner seems to have some issues recently (or at least more than I remember). Typically a controller handles about 500 probes, so it will take some time before we will get controllers in other places in the world. > > Quite a bit of atlas backend logic depends on probes having just one controller at a time, so this is unlikely to change soon. > > Sending probes to different controllers happens automatically, but it happens on a time scale of around 6 hours. It seems that the issue at Hetzner was less than 2 hours. However, with all controllers for software probes at Hetzner, a long failure at Hetzner would indeed impact all software probes. In this case, why not have the software probes set up with a fall-back RIPE Atlas Anchor (controller)? E.g. - Setup a list of 2 or more Anchors in a hierarchical order, - If the software probe cannot reach the primary Anchor for more than 10-20 minutes., fall-back to the next Anchor reachable, - Retest connectivity to all configured anchors every 6 hours, - Revert to use the first reachable anchor in the locally configured list (a hierarchical order). * The above idea assumes an Anchor being able to temp. handle more than the default ~500 probes per Anchor, plus co-location diversity of >= 2 providers and >= 3 anchors. -- Chriztoffer

Far remote probe 34512 offline but partially works
by ripe＠brite.cz 27 Jul '20

27 Jul '20

Hi team, I have probe 34512 in distant location [not able to have it checked physically for some more time], it shows offline since 2020-07-21, no SOS messages listed since 2020-05-16. But other devices connected to the same router do work online, and also the router keeps sending me Log Messages via internet so its internet connection has to be working fine. Router log shows DHCP request getting from the Probe every 12 hours, as usually: 2020/07/27 18:51:44 Info 93-153-42-167.customers.tmcz.cz daemon dnsmasq-dhcp DHCPACK(eth1) 192.168.222.220 c0:25:e9:a8:57:96 2020/07/27 18:51:44 Info 93-153-42-167.customers.tmcz.cz daemon dnsmasq-dhcp DHCPREQUEST(eth1) 192.168.222.220 c0:25:e9:a8:57:96 The router itself is behind NAT and I'm not able to remote to it and proceed with further investigation. From the Log above I see the Probe is running and keeps requesting DHCP requests as usually, so not sure how it could show offline. Do you have any further logs or a way how to try to resurrect the Probe remotely? Thank you Jiri

Issue in rendering built in graphs
by Anurag Bhatia 08 Jul '20

Hello Seems like something broken at the RIPE backend. Unable to render built-in graphs. I am getting this on any of the probes I check: URL: https://atlas.ripe.net/probes/17011/#!tab-builtins [image: Screenshot 2020-07-07 at 10.30.24 PM.png] Anyone with an idea on what's going around? -- Anurag Bhatia anuragbhatia.com

probe offline/lock up
by Bryan Fields 06 Jul '20

06 Jul '20

I had an interesting alert yesterday, as my probe 54858 said it was offline. I was unable to ping it from the router port it's directly connected to, but did some some traffic on the port via the counters. There was a fresh ARP entry as well. I power cycled it and it came back online. I was then able to ping it via v4 after it DHCP'd it's address. v6 pings were working to it's SLAAC address too. It has not gone offline now, but I am noticing pings on v4 are not working at all again. v6 seems unaffected. Is this normal or is there a problem with my probe? I've never really taken this close of a look before, I'm unsure if it has an issue or if this is normal. Thanks, -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net

Ripe atlas: Fetch all probes data
by Niraj Sorathiya 29 Jun '20

Hello Team, Is there any way to fetch all probes data at once using "ripe.atlat.coustea" python API instead downloading dump provided by Ripe team ? Thank you ! Regards, Niraj

retrieve past measurements
by Fabiano D'Agostino 29 Jun '20

29 Jun '20

Good evening, I am trying to retrieve streaming data as described in the guide here: https://atlas.ripe.net/docs/result-streaming/ I was able to retrieve the measurement results using stream_type="result", but when I try to retrieve past measurements with the startTime flag it is not working. How can I solve? Thanks in advance, Fabiano
