Re: v1 probe loses connection after a while (and webui needs more love)

i meant there were recent updates to ripe atlas i noticed the recent power outage is separate issue but i noticed problems appearing at same time. as it is always powered, i'm suspecting it now had to reconnect or maybe it also reflashes new updates on boot, so now it's different. but i don't know what's happening here. hence the question!

Cannot download periodic measurements
by Shihan Lin 07 Aug '24

07 Aug '24

Hi all, I recently tried to download some public periodic measurements that I launched in May, but I find I cannot download the full result by API or by web interface. One is example is measurement 72054485, which is launched on May 20th. I transformed the start time and end time to timestamp, which is 1716250200 (2024-05-21 00:10) and 1716336540 (2024-05-22 00:09), and when I used the following API to download the results, it responds me with empty file. https://atlas.ripe.net/api/v2/measurements/72054485/results?start=171625020… I cannot download it either when I use the web interface. Any idea about how to solve it? Thank you! Best, Shihan

Lot of disconnects for Probe #27262
by Victor TALVAZ 05 Aug '24

05 Aug '24

Hi, Since some days i suffer for highly disconnects, connections to RIPE Atlas are disconnected every 10 minutes, or 50 but nothing more. I tried to change USB stick, and tried to put it on another switch/router. Seems the same. I have tools to monitor my FTTH line from another place, and it looks stable on both IPv4/IPv6. I see the disconnects but there is no alert sent in SOS History and the Probe doesn't reboot. I wonder what more I can do to see the issue ? Can it be an issue on Atlas side ? Maybe somebody from the RIPE see more infos that what I see. PS: I can see dates on connect/disconnect that change sometimes, it's really weird. Thanks for your help, Victor Talvaz

v1 probe loses connection after a while (and webui needs more love)
by Sulev-Madis Silber 04 Aug '24

04 Aug '24

i have a old probe here. it's v1 or maybe it was v2. anyway... there were recent updates to system and i had to take everything off power for a few hours. after i put i back and it really is always on here, despite being home. the probe didn't reconnect. i don't have it on pdu. i have never needed it to cycle it before in previous 11 years. taking power off fixed it. now it's down again while on power and network. i went to looked what my atlas vlan does and found probe having both v4 and v6. and looks like it periodically tries to reconnect to ssh, gets reply and then... what happens next? it reports fw issue and trying to reconnect. but what kind of issue suddenly appeared when i have done none of fw changes. it's connection is via fbsd box i have full control over. can somebody check wtf is it and maybe fix it if needed. or maybe it just is too old? it works tho. i'm amazed how long it has been running. before next power cycle, can somebody diagnose it. it seems to connect out well? but just v4 i see. v4 is natted there while v6 is native and routed directly. probe id is 4415 p.s.: new webui tiles are really easy to accidentally mess up with finger on phone screen. never know when you scroll page and when you drag and drop. it's annoying

Probe #7030 may have specified the wrong location
by Marek Küthe 04 Aug '24

04 Aug '24

Hello, I noticed the probe #7030 [1] during the measurement #76522525 [2]. It has China as its location. However, the probe itself probably belongs to AS23961 [3]. You can see their locations on their website [4]. However, the probe does not appear to be in China, but in Hong Kong. Hong Kong is listed as an extra country/region in the RIPE NCC Atlas and I think this should be used accordingly so as not to falsify results. Could someone adjust the location?

REST API: Optional Fields for DNS Measurements
by Richter, Robert 03 Aug '24

03 Aug '24

Dear fellow RIPE Atlases, I am looking for the full definition of all optional field of the RIPE Atlas REST API for creating measurements. Especially the one for creating a DNS measurement. I only find the one defining the required attributes for a DNS measurement. But is there also a list constituting the optional fields? Best regards, Robert
