That may only be half of the truth... the others don't complain because they have 802.11a (5GHz) cards and found that the network has been working great for them this week. Of course they won't talk about that either, because one of the reasons why 802.11a works so well is that its users are still in the minority. For me, IPv4 connectivity from the meeting to my "home" network in Europe has been very good, and IPv6 connectivity even better. The only problem I had with IPv6 was the usual one: bogus IPv6 Router Advertisements from laptops configured as 6to4 routers. Right now these bogus RAs all seem to be coming from IPv6 link-local address fe80::204:23ff:fe7a:fb3e (MAC address 00:04:23:7A:FB:3E). Googling these addresses shows that the same address was active at IETF62 and IETF63. Hm, maybe we should track that one down next time... Anyway, I finally learned how to configure filters on my Linux laptop, and found that the following command (as root) makes my box ignore RAs from that particular address: ip6tables -A INPUT -s fe80::204:23ff:fe7a:fb3e \ --protocol ipv6-icmp --icmpv6-type router-advertisement \ -j DROP Hope this is helpful to some, -- Simon. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
