edst 193.0.0.228 in traceroute results
by Yang Yu 13 Nov '15

Hello, In https://atlas.ripe.net/measurements/2928258, I did a UDP traceroute. "edst":"193.0.0.228" from first hop and second hop somehow showed up in the results after the last hop that responded to traceroute, which should have been a reply to buil-in measurement to tt01.ripe.net. And under maps tab the result is presented with the first 2 hops showing up after several non-responding hops. Is this a bug? I actually see it happening quite often in atlas traceroute results with firmware > 4680. Another example is https://atlas.ripe.net/measurements/2928262 >>> https://atlas.ripe.net/docs/bugs/ 2015-03-04 Before firmware 4680, traceroute could experience interference from other measurements. In general, periodic traceroutes did not interfere with other periodic traceroutes, but could experience interference from one-off traceroutes. Typically, this interference will show up in the 'edst' field. This problem was fixed in 4680. Thanks. Yang

Feature request for IP record route feature in RIPE Atlas
by Pavel Odintsov 11 Nov '15

11 Nov '15

Hello, dear Atlas Team! As host of RIPE Anchor #6111 I have some feedback about your awesome service! Thanks for your Great Job in measuring Internet! I would like to ask very important feature for measuring reverse trace route. I'm speaking about IP record route option which could track up to 9 hops of reverse path. I want to know path to my hosts from networks who haven't RIPE Atlas. Actually I could not implement this feature due to 9 hop restriction in IP header. But RIPE Atlas offer really huge coverage over the World and we could reach really any host with <7 hops. But we haven't this feature in RIPE Atlas. Finally with this feature we could build full adjacently map over all the World. I have checked implementation details here https://labs.ripe.net/Members/philip_homburg/ripe-atlas-measurements-source… Looks like we need to build separate libevent based toolkit for this task or add this feature to ping tool. But unfortunately I could not find any docs about deploy of RIPE source code for development. Could you share some information? -- Sincerely yours, Pavel Odintsov

RIPE Atlas anchor self assembly
by Michela Galante 10 Nov '15

10 Nov '15

Hi everyone, Some people on this list have been asking about the possibility of purchasing hardware for a RIPE Atlas anchor by themselves and assembling it. This is indeed possible. However we do not recommend it because if the assembled hardware is not exactly to our specifications, we will not be able to use it as an anchor. If you still wish to assemble an anchor by yourself, you can find step by step instructions here: https://atlas.ripe.net/docs/anchor-installation/ Please, note that you do need more than the Soekris box. The anchor consists of: • Soekris Net6501-70 board • 1U 19-inch rack-mounted case • Intel SSD 525 or 530 series 240GB mSATA SSD More requirements are listed here: https://atlas.ripe.net/get-involved/become-an-anchor-host/ If you have more questions about anchors, please email to atlas(a)ripe.net and we will be very happy to help you. Best regards, Michela Galante Measurements Community Building RIPE NCC

ntp built-in measurements?
by Bajpai, Vaibhav 04 Nov '15

04 Nov '15

Dear RIPE Atlas, Do the probes not run (new) NTP measurements as built-in measurements? — I was glancing over the measurement data pushed by my probe, but I do not see any NTP measurement data. Although, when I try to provision a UDM, I do get an option to schedule an NTP measurement. Thanks!
