RIPE Atlas and nagios status-checks
by Robert Kisteleki 07 Dec '16

07 Dec '16

Dear All, The following message may be of interest to you if you're using Nagios (or variations like icinga) to query RIPE Atlas for status-checks. Yesterday morning our operations team made a change to the service configuration such that atlas.ripe.net only answers queries if they have proper Host: headers set. This is arguably a good operational practice, so we'd like to enforce it. However, one of the users running said nagios checks noticed that this causes 403 answers instead of the expected behaviour. We concluded that this is because the check_http plugin doesn't always set the Host: header. According to our statistics in total 12 users are affected, and since we could not foresee this problem, we temporarily reverted our configuration to the old settings. The fix on the client side is easy: one needs to add "-H atlas.ripe.net" parameter (or a similar change depending on forks and versions) to the checks. We'd like to ask our user to apply this change in the next two weeks in order to send well-formatted requests to our service. Thank you, Robert Kisteleki RIPE NCC

tp-link probev3 tl-mr3020
by folkert 25 Nov '16

25 Nov '16

Hi, I have one of those tp-link probes, a v3 it looks like. Now when I got it, I was warned to put it on a 1A powersource. Now that is a bit of a problem so I started to measure its power usage to verify if I could maybe run it on a smaller power supply. What I measure is 0.14A upto 0.23A - that should easily be powered by a 0.5A power supply I think. As I'm not an electronics expert I'm now writing this message for confirmation: am I right about the power usage? Or ar there situations where it would be using a lot more power? Thank you, Folkert van Heusden -- ---------------------------------------------------------------------- Phone: +31-6-41278122, PGP-key: 1F28D8AE, www.vanheusden.com

Emails Regarding Probe Connection Issues
by Alun Davies 17 Nov '16

17 Nov '16

Dear members of the RIPE Atlas community, It was recently called to our attention that certain emails we send out to RIPE Atlas probe hosts, concerning probe connection issues, have been somewhat abrupt in their tone. We are working to address the issue. While we devote a great deal of effort to ensuring that any correspondence we send out is both informative in content and appropriate in tone, we greatly appreciate feedback whenever it is felt that such goals have not been met. We would like to take this opportunity to once again thank all RIPE Atlas probe hosts for their ongoing participation. Best regards, Alun Davies (RIPE NCC)

Probe marked as offline, but it's online...
by Christian Schrötter 10 Nov '16

10 Nov '16

Hello Atlas users! I've connected my probe to a new network environment, to test everything before the big migration starts. It came up again immediately and displayed it's new network details at the WebUI. For the first time there was an IPv6-ULA prefix visible. The router (OpenWrt 15.05) supports full IPv6 via tunnel, but it's not advertised to the probe's VLAN and blocked by firewall rules. Everything seems to work, good! I've switched it off/on for several times, went back to the old router/modem and powered it on again. After some hours I've checked the WebUI again: My probe is offline! :-( I've tested it again on the new router: Offline! Once again on the old setup: Offline! Untouched default router/modem from my ISP: Offline! Current LED status: (from 1-5; power to button) > on > off > slow blink > on > on SOS-DNS-history from Wireshark: (switch port mirrored to my analysis interface) > Standard query 0x0002 AAAA U.*************.sos.atlas.ripe.net > Standard query response 0x0002 AAAA 2001:67c:2e8:11::c100:1337 > Standard query 0x0003 A U.*************.sos.atlas.ripe.net > Standard query response 0x0003 A 193.0.19.55 The probe is online and communicates with many servers. Looks like the built-in tests are running fine. There is NTP, DNS, ICMP, UDP and HTTP traffic. But it's still offline at the WebUI. I've double and triple checked everything on my side. Any ideas what's going wrong? -- With kind regards, Christian Schrötter
