Probe and firewall settings?
by Tim Chown 15 Jan '18

15 Jan '18

Hi, At https://atlas.ripe.net/about/faq/#so-which-services-do-i-need-for-my-probe-… it says "The absolute minimum set is DHCP, DNS and outgoing TCP port 443 (HTTPS) in order to allow the probe to connect to the network. However, this in itself is not enough to do measurements, which is the entire focus of RIPE Atlas, so you should also allow ICMP, UDP (DNS + traceroute), TCP for traceroute and HTTP(S)." What specific ports and protocols are required for routine operation and for inbound or outbound measurements to be configured? I think the above info could be a little more detailed (having had questions asked of me). Many thanks, Tim

beta status page vs. ipv6 only network
by Bjoern Buerger 15 Jan '18

Hi, One of our probes has a warning "IPv4 Doesn't Work Properly" on the beta Status Page, along with a "IPv4 doesn't work" Tag on the main page. While this is technically correct, the cause is simple and nothing is broken. We just removed IPv4 from that specific network segment (because it's not needed anymore). Is it possible to somehow tag the probe as "single stack on purpose" in the configuration page? Thanks in advance, Bjørn

#6262 Disconnectted
by Stanish Stanishev 12 Jan '18

12 Jan '18

Hello, Yesterday i got a notification that one of the our Anchors - #6262 has disconnected from Atlas. According to its Current Status info - DNS Problem Suspected. I see the anchor is configured to use the following DNS Resolvers - 8.8.8.8 and 2620:74:1b::1:1. The anchor responds to pings and is reachable from the world. Also the resolvers 8.8.8.8 are 2620:74:1b::1:1 reachable from the anchor's uplink router. So apart from checking the anchor's connectivity and DNS resolvers I don't have much left to do in order to get the anchor connected again. Has anyone faced this situation before ? Thanks Stanish Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Minor changes in the probe archive API
by Viktor Naumov 10 Jan '18

Dear colleagues, We made some changes to the probe archives API. The changes relate to the use of another storage back-end. In addition to the "date" URL argument, which returns the all probes dump for the given date, the new version enables ranges of dates to be specified for all or selected probes. The example below will return dumps for probes 1, 5, 81, 82, 83 for dates in the range [2018-01-03, 2018-01-06): https://atlas.ripe.net/api/v2/probes/archive?/api/v2/probes/archive?date__g… Best regards RIPE Atlas Team
