Second, I've never tested how well the init scripts expand "::" notation in IPv6 addresses. They may work fine, or you may have to expand it yourself, e.g., IPV6_DEFAULTGW=2000:8000:12:6:0:0:0:1 When doing static IPv6 configuration, it's probably best to set IPV6_AUTOCONF=no Even if all that works, however, I'm not sure where you got the 2000:8000:12:6::/64 prefix. I think the current range of routable addresses starts at 2001:0000::1. I doubt your packets will be able to traverse the Internet with a 2000:8000:: address. If you want to do IPv6 locally, you should be able to use the link-local address space, fe80::. If you want a globally valid IPv6 address, your Internet provider will have to give you a route or you'll have to set yourself up with a IPv6 tunnelling service. > ■ link up > # ethtool eth1 > Settings for eth1: > ～ > Link detected: yes > > # ifdown eth1 > # ifup eth1 > # ifconfig eth1 > eth1 Link encap:Ethernet HWaddr 08:00:27:83:74:54 > inet addr:192.168.11.8 Bcast:192.168.11.255 Mask:255.255.255.0 > inet6 addr: fe80::a00:27ff:fe83:7454/64 Scope:Link ←○ > inet6 addr: 2000:8000:12:6:192:168:11:8/64 Scope:Global > > > ■ link down > # ethtool eth1 > Settings for eth1: > ～ > Link detected: no > > # ifdown eth1 > # ifup eth1 > # ifconfig eth1 > eth1 Link encap:Ethernet HWaddr 08:00:27:83:74:54 > inet addr:192.168.11.8 Bcast:192.168.11.255 Mask:255.255.255.0 > inet6 addr: 2000:8000:12:6:192:168:11:8/64 Scope:Global > > > Missing fe80::a00:27ff:fe83:7454/64. The link-local address should always be present, but I've never done a lot a ifdown/ifup operations to see how they can muck things up. I'd try "service network restart" to get full interface initialization. -- Paul Heinlein heinlein at madboa.com 45°38' N, 122°6' W
