Iso installation issue with RIPE Atlas anchor for LACNIC (uy-mvd-as28000)
by Elisa 07 Jan '25

07 Jan '25

Good morning, We received the ISO image to install the anchor but we encountered an issue. When we execute the "Install RIPE NCC Atlas Anchor" (see image) at some point the machine tries to resolve ks.atlas.ripe.net <http://ks.atlas.ripe.net/>, but it isn't connected to the network yet because to connect to the network we have to be inside the operating system, the installation process can't continue. We've been following instructions in: https://atlas.ripe.net/docs/howtos/installing-atlas-anchor.html and the machine has the following characteristics: 1 CPU type x86-64-v2 4 GB ram 50 GB disco Se carga la iso del disco local de Proxmox Can you help us move forward?

Probe on ctr-dub-hw01 disconnected
by Ernst J. Oud 25 Dec '24

Hi, My probe 55795 disconnected from ctr-dub-hw01. Could it be that this controller has an issue? My other probes on other controllers are fine. Regards, Ernst J. Oud

Conflicting tags for resolver
by RIPE 22 Dec '24

22 Dec '24

Hi, I just noticed my probe (1008458) shows a strange status: System Resolves A or AAAA Records Incorrectly But looking at the tags I see both the resolves correctly and the resolves incorrectly tags are set for both A and AAAA. That looks like a strange combination of tags. Any idea what’s causing this ? Cheers, Paul

cannot forward src on fbsd
by Sulev-Madis Silber 21 Dec '24

21 Dec '24

i have fbsd box with pf that routes my traffic i get this endlessly: cannot forward src fe80:24::4e6d:580f:fc89:81ae, dst 2001:7d0:8437:13bf:da58:d7ff:fe 03:1274, nxt 58, rcvif vlan3, outif vlan91 cannot forward src fe80:24::4e6d:580f:fc89:81ae, dst 2001:7d0:8437:13bf:da58:d7ff:fe 03:1274, nxt 58, rcvif vlan3, outif vlan91 cannot forward src fe80:24::4e6d:580f:fc89:81ae, dst 2001:7d0:8437:13bf:da58:d7ff:fe 03:1274, nxt 58, rcvif vlan3, outif vlan91 sometimes androids do this a few times, but probes do it all the time. multiple hw ver probes. for a decade i get few obscure results when i look that up but don't know what this is or why i tried to sniff and iirc i found weird icmp ttl exceeded packets i think kernel is correct on that cannot forward part. i'm unsure what measurements my probes actually run the src is apparently some linklocal, dst is my probe v6, recv if is vlan3, this is my v4/v6 wan to isp, out is vlan91, this is dedivated v5 probe vlan in local network did i misconfigure something or isp or ripe or else or? does it affect measurements? i'm not sure what this issue is. i think you can't forward that traffic indeed, from ll ip to global ip? google doesn't help to even shed some light on this weird behaviour, let alone any fix doesn't bother me, just curious i'm not surprised, as this device sends and receives traffic i don't have any control of. and is specifically ip measuring device so, unsure... about all this!

Requested and participating probes
by Huseyn Gambarov 13 Dec '24

13 Dec '24

Hello. I am currently working on a project that heavily relies on Ripe Atlas Ping measurements. During the development, I noticed that sometimes when, let’s say, I request 3 probes, only 2 are participating in the measurement. In the Ripe Archive, I found that there was a similar discussion here - https://mailman.ripe.net/archives/list/ripe-atlas@ripe.net/thread/D6QZS4WC5… I have two questions, that I could not find answers to, and I would be very grateful if you could help me with them. First, in the mentioned discussion it is said that there are multiple reasons why fewer probes are participating and there is ongoing work to allow users to obtain information about specific conditions that occurred during the measurement creation. Can you tell, if there is a way to get that information via API? Second, do you know if there is a reasonable timeout to wait before a new attempt to reschedule the probe that failed to participate in the first measurement? Thank you for your help. With regards, Huseyn Gambarov.

Understanding how to use the `paris` parameter
by Bhaskar, Abhishek Vasisht 13 Dec '24

13 Dec '24

Hello y'all! I'm a PhD student from Georgia Tech and had a question about the "paris" field when performing traceroute measurements. The RIPE documents states that ```Paris - A number greater than 0 will indicate the number of variations to be used for a Paris traceroute. Setting the value to 0 makes the measurement use the standard traceroute``` But regardless of what Paris value I give to the traceroute measurement, I only get one path with a single paris_id. I would expect that if I gave a paris value of 10, I should see 10 potential variations of the path between A and B, correct? Please correct me if I'm wrong. Here is an example measurement https://atlas.ripe.net/measurements/84562046 Thanks! -- Abhishek Vasisht Bhaskar Student, PhD in Computer Science Georgia Institute of Technology https://abhishekvasishtb.github.io/

MTU tracepath in RIPE atlas

Hello! Maybe some people here know the Linux tracepath application. It tests the PMTU to a destination. Could such a feature be implemented in RIPE Atlas? -- kind regards Marco Send unsolicited bulk mail to 1734020167muell(a)stinkedores.dorfdsl.de
