Linux Foundation Says All Major Distros Are IPv6 Compliant
ruphus13 points out news from the Linux Foundation, which announced that all major Linux distributions meet certification requirements for the US Department of Defense's IPv6 mandates. The announcement credits work done by the IPv6 Workgroup, whose members include IBM, HP, Nokia-Siemens, Novell and Red Hat. Quoting:
"Linux has had relatively robust IPv6 support since 2005, but further work was needed for the open source platform to achieve full compliance with DoD standards. The Linux Foundation's IPv6 workgroup analyzed the DoD certification requirements and identified key areas where Linux's IPv6 stack needed adjustments in order to guarantee compliance. They collaboratively filled in the gaps and have succeeded in bringing the shared technology into alignment with the DoD's standards."
I, too, am using 6to4 at home in order to get rid of NAT, but lately I've been having great trouble when traveling around with my IPv6-enabled laptop (running Debian).
See, whenever I get to a public access point (which uses public IPv4 addresses, rather than a private 192.168.x.x net) it turns out that any Vista computers connected to the same link auto-configure themselves to use 6to4 and then advertise over ICMP that they are willing to route traffic through their 6to4 net. However, it turns out that they just drop the traffic! My laptop, not knowing that, though, will try to route IPv6 traffic through them nevertheless, which just makes every IPv6 site (including my own) stop working. Viva Vista!
Does anyone know why Vista does this, and whether it's possible to prevent or work around it somehow?
