$ sysctl net.ipv6.conf.eth2.use_tempaddr
net.ipv6.conf.eth2.use_tempaddr = 2
# (as per the default /etc/sysctl.d/10-ipv6-privacy.conf in 12.04)
# Add a static IPv6 address:
$ sudo ip addr add 2001:470:9321:f003::1122/64 dev eth2
# Verify that it has been set up, and that a temporary address and a SLAAC
address also exist:
$ ip -6 addr list dev eth2
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:470:9321:f003:74e3:aa2b:7ee5:c002/64 scope global temporary
dynamic

inet6 2001:470:9321:f003::1122/64 scope global
valid_lft forever preferred_lft forever
inet6 fe80::6c97:24ff:fe3f:263b/64 scope link
valid_lft forever preferred_lft forever
# Disable RFC 4941 temporary addresses:
$ sudo sysctl net.ipv6.conf.eth2.use_tempaddr=0
net.ipv6.conf.eth2.use_tempaddr = 0
$ ip -6 addr list dev eth2
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 fe80::6c97:24ff:fe3f:263b/64 scope link tentative
valid_lft forever preferred_lft forever
I.e. on setting use_tempaddr=0, _all_ IPv6 addresses are removed,
including statically-configured and non-temporary SLAAC-configured
addresses. (The link-local address reappears quickly but the
'tentative' flag indicates that it has been newly re-added. The SLAAC
address reappears after a slightly longer interval as the kernel
continues to undergo SLAAC, but the static address is gone forever
unless manually reinstated.)
The same happens if use_tempaddr is changed from 0 back to 2.
The expected outcome is that only temporary addresses are affected by a
change to use_tempaddr.
