Has anyone added scripts to dhcpd.conf to control DDNS AAAA records based on MAC address?
It's such an obvious idea, that someone must have done it! [[[ Background for those who don't routinely use IPv6, DDNS and Bind. When a network interface comes up, it can autoconfigure itself with an IPv6 address based on its MAC address, combined with a default prefix that is broadcast from an IPv6 router somewhere else on the network. Typically, in an IPv4 system, the system will also request an IPv4 address using a protocol called DHCP (Dynamic Host Configuration Protocol). With the request, the system can pass a hostname, and it's fairly trivial to configure the DHCP server to insert this into the DNS server's tables, with an A record matching name to IPv4 address. When the lease expires, or is explicitly released, the A record is removed. I want also to add the AAAA record for the IPv6 address that would be auto-configured. It's fairly easy to write a script to do this, with appropriate checks and balances (e.g., use ping6 to make sure that the client actually uses IPv6). It *should* be possible to do it entirely inside the dhcpd.conf file for dhcp3. And I don't want to reinvent the wheel if there's already something out there. ]]] -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
