PXE doesn't support IPV6 and I don't think it'll in the near future as that'd require a change to all existing and upcoming BIOS. > 2. Do any PXE enabled network cards actually support IPv6?

I'd suspect none, during my tests here and as part of the design for the next ltsp-cluster infrastructure, everything can be IPV6 aware and very likely IPV6-exclusive, except the PXE part. > I'm not suggesting this should all work right now, I'm just curious to know > how far LTSP is from working over IPv6. The way I think IPV6 will work with LTSP when we get there is: - PXE boot using a regular IPV4 setup and get the kernel + initrd from that (extremely short lease as that only need to last for 30s or so) - initrd does the IPV6 setup (radvd or dhcpv6) - boot continues in IPV6-only So basically, you still need IPV4 dhcp and tftp server but the chroot itself can be IPV6-only, that should work correctly and I don't see any reason why it wouldn't work already (other than the minimal change in the initrd required to get rid of the IPV4 dhcp). > Gavin - -- Stéphane Graber Ubuntu developer http://www.ubuntu.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAktMj4oACgkQjxyfqkjBhuw+0gCfRk+dzLKYyr19IaoXUn/GRcEt jOEAnjQ913RRw29RVs1Yw1J+ner1QM5B =6A0C -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _____________________________________________________________________ Ltsp-discuss mailing list.
