$ 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:

# Verify that it has been set up, and that a temporary address and a SLAAC address also exist:
$ ip -6 addr list dev eth2

# 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

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. |
