#191399 — IPv6 SLAAC and RFC 7217

FromJohn Naggets <hostingnuggets@gmail.com>

Message-ID<vasxr-232-11@gated-at.bofh.it>
Hi,

I was wondering if there is a "standard" way in Debian 9 through the
/etc/network/interfaces file to enable/force using a stable private
IPv6 address using SLAAC as specified in RFC 7217?

Any one already managed to do that on a Debian 9 client? or know how to do that?

Cheers,
John

no personal experience, but you should look at dhcpcd, with support
for RFC 7217. AFAIK enabled in the default configuration.

best regards

Side note, to avoid confusion:

  dhcpcd is a different software than isc-dhcp-client.

I have never tried it but <https://unix.stackexchange.com/a/255955>
seems to suggest that you would set the stable_secret sysctl and
then it would work automatically after that.

You could set the sysctl from /etc/network/interfaces or from
/etc/sysctl.d/ or just by some other script.

Cheers,
Andy

Thanks Andy for the tip about the stable_secret sysctl, I will try
this out soon and see how it behaves.
