I want to prepare for coming day zero and activate ipv6 privacy extensions. After some reading on the subject, my /etc/sysctl.conf looks like stated below. But after restart, my ipv6 adress is still valid forever.

Btw, "modprobe ipv6" terminates successfully, but "lsmod" still shows no module called ipv6.

# ip -6 addr show

valid_lft forever preferred_lft forever
4: wlan0: <BROADCAST> mtu 1500 qlen 1000
inet6 fe80::1e65:9dff:fe79:2b19/64 scope link
valid_lft forever preferred_lft forever

/etc/sysctl.conf

net.ipv6.conf.wlan0.use_tempaddr = 2
net.ipv6.conf.default.use_tempaddr = 2

net.ipv6.conf.eth0.temp_valid_lft = 86400
net.ipv6.conf.wlan0.temp_valid_lft = 86400
net.ipv6.conf.default.temp_valid_lft = 86400
net.ipv6.conf.all.temp_valid_lft = 86400

net.ipv6.conf.eth0.temp_prefered_lft = 86400
net.ipv6.conf.wlan0.temp_prefered_lft = 86400
net.ipv6.conf.default.temp_prefered_lft = 86400
net.ipv6.conf.all.temp_prefered_lft = 86400

ipv6 is compiled statically into the kernel (due to sysctl requirements); therefore it won't show up in lsmod, but is still present and usable. Unfortunately I can't test IPv6 myself.

Btw., did you try to add "privext 2" to your inet6 stanza in /etc/network/interfaces (refer to interfaces(5))?
