Package: network-manager Version: 0.9.10.0-6 Severity: normal I have an dhcp6 router but my machine never gets an IPv6 address. After looking around it is clear that duplicate address detection is misfiring and causing me problem. For example running:
echo 0 | sudo tee /proc/sys/net/ipv6/conf/*/accept_dad And reconnecting to the network brings up an IPv6 address. This seems very similar to bug #705996 in ifupdown but I'm not sure. Here is the contents of /var/log/syslog as I join the network: Mar 24 22:11:16 cobra NetworkManager[1930]: <info> (wlan0): supplicant interface state: associating -> associated Mar 24 22:11:17 cobra NetworkManager[1930]: <info> (wlan0): supplicant interface state: associated -> 4-way handshake Mar 24 22:11:17 cobra wpa_supplicant[2466]: wlan0: WPA: Key negotiation completed with 08:86:3b:25:78:e6 [PTK=CCMP GTK=CCMP] Mar 24 22:11:17 cobra wpa_supplicant[2466]: wlan0: CTRL-EVENT-CONNECTED - Connection to 08:86:3b:25:78:e6 completed [id=0 id_str=] Mar 24 22:11:17 cobra NetworkManager[1930]: <info> (wlan0): supplicant interface state: 4-way handshake -> completed Mar 24 22:11:17 cobra NetworkManager[1930]: <info> Activation (wlan0/wireless) Stage 2 of 5 (Device Configure) successful.
