IPv6 is currently not working and it's still 1000 Full on both sides ("show int GiX/Y" and "ethtool eth0"). No errors in "ethtool -S eth0" or "show int GiX/Y". "ethtool eth0" output is the same as yesterday. Here's the addresses and routing table as they are now, and have been since reboot: $ ip -6 a 1: lo: mtu 16436 inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: mtu 1500 qlen 1000 inet6 2a00:800:752:1::5c:2/112 scope global valid_lft forever preferred_lft forever inet6 fe80::224:81ff:fea3:4424/64 scope link valid_lft forever preferred_lft forever $ ip -6 r sh 2a00:800:752:1::5c:0/112 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via 2a00:800:752:1::5c:1 dev eth0 metric 1024 mtu 1500 advmss 1440 hoplimit 4294967295 $ ip -6 ne sh 2a00:800:752:1::5c:1 dev eth0 lladdr 00:22:55:17:4b:80 router STALE [try ping6 again, no reply] $ ip -6 ne sh 2a00:800:752:1::5c:1 dev eth0 lladdr 00:22:55:17:4b:80 router DELAY [try ping6 again, no reply] $ ip -6 ne sh 2a00:800:752:1::5c:1 dev eth0 lladdr 00:22:55:17:4b:80 router REACHABLE [try ping6 again, no reply] Configured network with /etc/network/interfaces: auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet static address x.x.x.x netmask 255.255.255.252 broadcast x.x.x.x gateway x.x.x.x up ip a a 2a00:800:752:1::5c:2/112 dev eth0 up ip r a default via 2a00:800:752:1::5c:1 dns-nameservers x.x.x.x dns-search xxxx.net --------- typedef struct me_s { char name[] = { "Thomas Habets" }; char email[] = { "thomas@habets.pp.se" }; char kernel[] = { "Linux" }; char *pgpKey[] = { "http://www.habets.pp.se/pubkey.txt" }; char pgp[] = { "A8A3 D1DD 4AE0 8467 7FDE 0945 286A E90A AD48 E854" }; char coolcmd[] = { "echo '. ./_&. ./_'>_;. ./_" }; } me_t; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
