Prevention of NTP reflection attacks using TTM systems
by Romeo Zwart 13 May '14

13 May '14

Dear colleagues, During the evening of Wednesday 8 January, the RIPE NCC received initial reports about the abuse of some of our Test Traffic Measurement (TTM) systems, specifically about the use of NTP in reflection attacks. Within 24 hours of receiving the first report, we adapted the NTP configuration on all our TTM hosts so that this specific type of attack is no longer possible using the TTM infrastructure. We would like to thank Gert Doering (SpaceNet) and Michael Hausding (SWITCH-CERT) for reporting the abuse to us. We’d also like to share this resource about securing NTP servers that you may find useful: http://www.team-cymru.org/ReadingRoom/Templates/secure-ntp-template.html We are taking this opportunity to remind you that we are nearing end of service for TTM. As we announced previously, TTM shutdown is scheduled for the end of Q1, 2014. RIPE Atlas, and specifically RIPE Atlas anchors, will provide much of the functionality of TTM. More details, including information about hosting a RIPE Atlas anchor, are available at: https://atlas.ripe.net/about/anchors/ Kind regards, Romeo Zwart RIPE NCC

... and six more RIPE Atlas anchors activated
by Vesna Manojlovic 13 Feb '14

13 Feb '14

Dear colleagues, We are proud to announce that six new RIPE Atlas anchors have been activated since my previous announcement last month: - se-sto-as59521, hosted by Aivivid in Stockholm, Sweden. - hu-bud-as12303, by BIX in Budapest, Hungary on behalf of RIPE NCC - fr-vbn-as199422, hosted by Rezopole/LyonIX in Lyon, France. - is-rey-as25509, hosted by Hringiðan in Reykjavik, Iceland. - nl-arn-as1140, hosted by SIDN in Arnhem, Netherlands - at-vie-as1120, by VIX in Vienna, Austria, on behalf of RIPE NCC This brings the total number of active anchors to 39. All RIPE Atlas anchors can be seen on this list, where logged-in users can access each anchor's measurements: https://atlas.ripe.net/anchors/list/ We are still accepting new applications from individuals and organisations interested in hosting a RIPE Atlas anchor. We are particularly interested in deploying anchors in the Middle East, Western Asia, Latin America and Africa, in order to add more geographical diversity to the measurement data. Learn more about RIPE Atlas anchors and the benefits of hosting an anchor at: https://atlas.ripe.net/about/anchors/ For detailed announcements and updates about RIPE Atlas, please join the RIPE Atlas mailing list: https://www.ripe.net/mailman/listinfo/ripe-atlas Kind regards, Vesna Manojlovic Measurements Community Building Team RIPE NCC

Dear colleagues, Status Checks is a new feature that allows you to integrate RIPE Atlas into any monitoring tool you currently use, such as Nagios or Icinga. Please find a new article on RIPE Labs that explains simple steps, gives an example, and points to our future plans: https://labs.ripe.net/Members/suzanne_taylor_muzzin/introducing-ripe-atlas-… Direct link: https://atlas.ripe.net/docs/status-checks/ We are pleased to announce this feature that the operators community has been asking for, and we are looking forward to both your feedback and success stories.
