This fails with > > no link-local IPv6 address for eth1 Even if your interface isn't able to configure a global IPv6 address, it should still get a link local address starting with fe80. Also, before modifying /etc/network/interfaces, I would advise doing ifdown eth1, modifying the file, and then ifup eth1. Instead of inet6 dhcp, I would suggest: iface eth1 inet6 auto My understanding is this should use either dhcp6, or RA/NDP to configure it. What does the following output: cat /proc/sys/net/ipv6/conf/all/disable_ipv6 cat /proc/sys/net/ipv6/conf/default/disable_ipv6 cat /proc/sys/net/ipv6/conf/eth1/disable_ipv6 Greg -- web site: http://www.gregn.net gpg public key: http://www.gregn.net/pubkey.asc skype: gregn1 (authorization required, add me to your contacts list first) If we haven't been in touch before, e-mail me before adding me to your contacts. -- Free domains: http://www.eu.org/ or mail dns-mana...@eu.org _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
