apple is enabling ecn by default.. this should be interesting. In which OS? Ah, found it: both. yeh, both. it basically means that ecn is going to be safe to enable by default soon linux's attempt at enabling ecn by default broke lots of things mercutio: more information on that? I saw that yesterday and enabled ECN on two OpenBSD machines. Nothing broke, though the only effect was that I saw like one ECN packet in tcpdump. Relevant, from 2011 https://www.caida.org/workshops/isma/1102/slides/aims1102_sbauer.pdf "Measuring the current state of ECN support in servers, clients, and routers" As memory serves, Cloudflare tried enabling ECN and things broke until they wrote some fixes. But haven't found a quick Google result oh I was thinking of when Cloudflare rolled out pMTU too many idiots blocking ICMP for pMTU? Think they hit some actual bugs that's possible too With whatever OS' implementation of it. http://www.theregister.co.uk/2015/06/17/apple_hosed_boffins_drop_0day_mac_ios_research_blitzkrieg damn m0unds mkb: wellt hre's a video that you can play in vlc.. hey guys, do you have VPS in India?
