raspbian.net/raspbian.org ipv6 peering problems
by Thomas Schäfer 25 Jun '19

25 Jun '19

Hello, I am not sure if I am right here with my question. Does someone measurements to the server of "raspbian"? Their hoster (bytemark, iomart, zayo?) seems not to be able to establish correct peerings. At least the peering to AS3320 is broken. I already contacted 3320. They say zayo doesn't fulfill the minimum security requirements. Are more peerings broken? Regards, Thomas

When to consider a measurement finished
by Wouter de Vries 25 Jun '19

25 Jun '19

Hi all, I am currently trying to do some measurements according to the following steps: 1. create a one-off measurement 2. wait for it to finish, by periodically polling the msmid and checking the status. 3. fetch the results However, the system takes a pretty long time to set the status to finished, even when all results are already in (maybe 10 minutes?). What heuristics/method do you recommend to determine whether to consider a measurement as finished? One option I consider is to periodically fetch all results for a given msmid and checking if the number of results matches the number of probes assigned to the measurement. However, I suspect that causes a much higher load on the infrastructure. Best regards, Wouter de Vries

Probe off-line for 6 days due to bad firmware signature
by Novak Jirka 25 Jun '19

25 Jun '19

Hello, my probe 22424 is off-line due to bad firmware signature error. I try to boot it without USB stick many times, then i change the USB stick (replace the old one with new one), but it doesnt solve my problem. Could you help me? This is the information from my status page: Bad Firmware Signature What does this mean? The probe's firmware signature is wrong. How can I fix this? Power-cycle the probe and wait for a couple of hours. If probe doesn't come online you should try to reinitialise or even replace your flash drive. Please use the following procedure: 1. Unplug the probe from its power source 2. Remove the USB stick from the probe 3. Plug in the probe WITHOUT the USB stick 4. Wait for ten minutes 5. Insert the USB stick If it didn't help repeat these steps using another working USB stick that is at least 4GB in size. NOTE: This must be done on a network with working DHCP! It will NOT work if you have configured your probe to use a static IP address, because this mini-operating system does not have access to any statically configure IP addresses or DNS resolvers. If you have configured your probe to use a static IP address, the only thing you can do is move it to a network with working DHCP. When the probe is listed as "connected" again, it is safe to move the probe back to its original location. However, please note that we advise configuring your probe to use a static IP address only if you feel it is truly necessary to do so. Thx, Jiri

RIPE Atlas anchor resolver update
by Anand Buddhdev 19 Jun '19

19 Jun '19

Dear colleagues, All the RIPE Atlas anchors run a caching DNS resolver. This resolver is used to look up names when a measurement requests name resolution using a probe's resolver. We have been running an older version of BIND for this service. In the coming days, we will be upgrading the version of BIND to the latest stable version (9.14). This version has dropped many work-arounds for various forms of brokenness in other DNS implementations. The effect of this is that a small number of domains hosted on broken DNS implementations cannot be looked up by this newer version of BIND. If you are running a measurement that uses an anchor's local resolver, and you find that some domain names are failing to resolve, it may be caused by this upgrade. Regards, Anand Buddhdev RIPE NCC

RFC1918 probes
by Mayer Hans 22 May '19

22 May '19

Dear All, Looking at the result of a traceroute measurement I see very often that first hop has a RFC1918 address. These days a found a result where the first 3 hops are showing something like 192.168.x.y Of course this could falsify the result especially for response time. Is there a way to select only Atlas probes which are located in non RFC1918 networks ? If not it would be nice to have such a possibility. Kind regards Hans -- Ing. Dipl.-Ing.

New probe tags proposal
by Antonios Chariton 18 May '19

18 May '19

Hello everyone, I believe it would be of interest to have system-assigned tags to probes based on whether their network is performing RPKI validation or not. This can be two new tags, “rpki-validating” and “no-rpki-validation”, or similar. The tags should be assigned per probe, using RIPE’s RIS Routing Beacons [1], by running system ping checks every hour / day. What do you think? Would this be something that you would find useful? Thanks, Antonis 1: https://www.ripe.net/analyse/internet-measurements/routing-information-serv… <https://www.ripe.net/analyse/internet-measurements/routing-information-serv…>

Communication with probes' owners
by Ponikierski, Grzegorz 02 May '19

02 May '19

Hi all! From time to time I find probes which has incorrect country in their description. For example #10333 supposed to be in US but from my measurements it looks like it is somewhere nearby Amsterdam. If something has 10ms RTT to target in Amsterdam, has hops with `nl-ams14a-ri1-ae8-0.aorta.net<https://stat.ripe.net/nl-ams14a-ri1-ae8-0.aorta.net>` description and has ASN for LibertyGlobal then this probe is rather in Europe. It takes some time to resolve such issue via RIPE team so maybe we can get a form to send direct and short message to probe owner to let him/her know that something is wrong with his/her probe and we ask for verification. What do you think about that? Regards, Grzegorz

All our atlas probes have reverted to DHCP

Hi, all of our four atlas probes have reverted from their fixed network configuration to DHCP which is a shame because there is no DHCP at their present locations. Also this not the first time it happend. Can someone explain why this happens and how to prevent this? This wastes a lot of time and effort every time it happens. Regards Sebastian

The hash for probe XXX would be obtainable via the portal, where you would need to look up probe's details anyway. Geert Jan

Measurement result issues for some RIPE Atlas anchors
by Philip Homburg 18 Apr '19

18 Apr '19

In April, we started investigating a strange traceroute result reported by one of the RIPE Atlas anchors. The conclusion of our investigation is that the probe upgrade process for the v3 anchor firmware has been leaving old measurement daemons running as well as starting new ones. This means that a gradually increasing number of measurements from the affected anchors have been performed multiple times more or less simultaneously. Because those processes were writing to the same file, this resulted in a lot of garbled results. Purely by chance, the weird result that triggered the investigation had the first part of one result and the last part of another result in a way that generated syntactically correct JSON. The net result is that for the last few months, measurements done by anchors may have resulted in multiple results at roughly the same time or no results because the results were rejected as invalid. For those who wish to check whether results for specific measurements were affected, the following links will direct you to lists of probe IDs for the affected anchors: https://atlas.ripe.net/api/v2/probes/?is_anchor=true&tags=system-virtual&fi… (VM anchors) https://atlas.ripe.net/api/v2/probes/?is_anchor=true&tags=system-v3-pc-engi… (v3 hardware anchors) We are working to resolve the issue and will keep you updated as and when we have more to report. We apologise for any inconvenience this might cause. Philip

Scheduled RIPE Atlas maintenance 2019-04-10 09:00 UTC
by Chris Amin 10 Apr '19

10 Apr '19

Dear RIPE Atlas users, We are planning on making a behind-the-scenes change to the RIPE Atlas database tomorrow in order to make the system more robust. Measurements scheduled during this time may be either rejected or delayed. Probes will continue to carry out measurements as usual so there won't be a gap in scheduled measurement results. The window for the maintenance is 2019-04-10 09:00 UTC until 12:00 UTC. We hope that it will be quicker than this and will keep you updated. Kind regards, Chris Amin RIPE NCC
