Hi,
(I just subscribed to the list, so sorry if my mail format isn't right
somehow. I quickly glanced at the archive and don't think what I offer
has been looked at, aside of a quick reference to the changelog when
the feature wasn't available in a stable release of dnsmasq yet)
ra_names is a feature introduced in dnsmasq 2.61, which is why I changed
the rules to build something newer (and figured I might as well take it
to 62)
Basically, it:
- does router-advertisment (not dhcpv6)
- when it gets a request for RA, it looks up if there is an active ipv4
lease for the same host via its MAC address, and if there is it adds
the to-be ipv6 to the local dns (assuming the host will take the dns)
- when it gets a dhcpv4 release it takes off the ipv6 dns record as
well
(since RA is stateless and doesn't give the host name, I couldn't figure
any better way without dhcpv6; I was about to hack something (with a
very large axe and radvd) when I found out they've done it already :D)
There are also modes for router-advertisment only which I haven't looked
at, and a dhcpv6 client implementation that I didn't try yet either.
The option I added is in the dhcp field, a "ra_name" option with the
prefix to announce in RAs, i.e.
config dhcp 'lan'
option interface 'lan'
option ra_names '2001:dead:beef::'
(Note: it doesn't seem to add the local dns with a fe80:: prefix)
Attached is the patch in svn format, feel free to ask if you prefer git's (I
personally do but didn't look hard enough for the git repository!)
Please give any comment and include something similar if you like it.
Rergards,
