RPKI validator 3: initial sync regression?
by nusenu 22 Mar '19

22 Mar '19

Hi, lately with validator 3 version > 370 it felt like rpki-validator 3 is less reliable and taking longer to download RPKI repository data (especially RIPE's) when starting for the first time when compared to older version (313) where it probably took less than 5 minutes after starting it to have the data for all regions. I reproduced this consistently. Can you think of anything that caused this? Does anyone else see this as well? Unfortunately I didn't find any changelogs and it is not obvious what version relates to what git commit since there are no git tags in the github repo. It would be great to have changelogs or git tags. thank you, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

Now on RIPE Labs: BGP Communities - A Weapon for the Internet
by Mirjam Kuehne 21 Mar '19

21 Mar '19

Dear colleagues, In these two articles on RIPE Labs Franziska Lichtblau and Florian Streibelt present a new attack vector on the Internet routing infrastructure using BGP communities: https://labs.ripe.net/Members/florian_streibelt/bgp-communities-a-weapon-fo… https://labs.ripe.net/Members/florian_streibelt/bgp-communities-a-weapon-fo… In the meantime this study won the Applied Networking Research Prizes and will be presented at the Internet Research Task Force meeting next week in Prague.

2019-03 New Policy Proposal (BGP Hijacking is a RIPE Policy Violation) to be discussed on Anti-Abuse Working Group Mailing List
by Marco Schmidt 19 Mar '19

19 Mar '19

Dear colleagues, A new RIPE Policy proposal, 2019-03, "BGP Hijacking is a RIPE Policy Violation", is now available for discussion. This proposed policy is of interest to both the Anti-Abuse and Routing working groups. The chairs of both these working groups have agreed to keep the discussion on one single mailing list to avoid duplication, and for formal consideration of the proposal within the RIPE Policy Development Process. You are therefore requested to share your feedback on this proposal with the Anti-Abuse mailing list. The goal of this proposal is to define that BGP hijacking is not accepted as normal practice within the RIPE NCC service region. You can find the full proposal at: https://www.ripe.net/participate/policies/proposals/2019-03 We encourage you to review this proposal and send your comments to <anti-abuse-wg(a)ripe.net> before 17 April 2019. Kind regards, Marco Schmidt Policy Officer RIPE NCC

RIS dumps, 0.0.0.0/0 routes and RPKI validator 3
by nusenu 18 Mar '19

18 Mar '19

Hello, I've got some really strange results when talking to rpki-validator 3's API and after some up and downgrading I concluded that it has to be in the RIS dumps (that was the only static data regardless of the validator version) and then I found the likely cause: AS15576 announcing 0.0.0.0/0 As of writing this email the first entry on this page: https://rpki-validator.ripe.net/bgp-preview but when we look at: https://stat.ripe.net/widget/as-routing-consistency#w.resource=AS15576 it is not there. I assumed RIPEstat uses the same data source (RIS) just with some less delay. Are 0.0.0.0/0 routes filtered by RIPEstat but included in RIS dumps? Should rpki-validator filter them out? thanks, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

RPKI Validator 3: RIS dump downloads - still plain HTTP
by nusenu 12 Mar '19

12 Mar '19

Hi, back in September I opened an issue on github [1] about RPKI Validator 3 fetching RIS dumps via plain HTTP connections, two weeks ago the issue got closed. First I was glad since I assumed the issue got closed because it is fixed but then I noticed that the issue still persists in rpki-validator-3.0-377 so I'm wondering why the issue got closed? thanks, nusenu [1] https://github.com/RIPE-NCC/rpki-validator-3/issues/50 -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu
