>>> wonderful, thats exacly what i need, also for ipv6. I've just pushed very basic client-side support for prefix delegation into the Darcs repository. It's completely untested, so you'll most likely need to do some debugging on your side.
darcs get http://www.pps.jussieu.fr/~jch/software/repos/ahcpd You use it by passing -P to the client. If prefix delegation is successful, it will pass one or both of AHCP_IPv4_PREFIX_DELEGATION or AHCP_IPv6_PREFIX_DELEGATION to the config script; you'll most likely want to do something smart in /etc/ahcp/ahcp-local.sh with it. To do: * test; * pick the lease with prefix delegation (currently it marks prefix delegation as optional, and just takes the first lease offer, whether it offers prefix delegation or not); * allow choosing the prefix length (the protocol allows that, but it's not implemented); * allow requesting just IPv4, just IPv6, or both (currently, both IPv4 and IPv6 are requested when -P is used). The server-side code is not ready yet -- in particular, I'm not quite sure what the right configuration is, do we want dynamic leases on prefixes, or do we want static leases that depend on the requestor's unique id? For the time being, I'm appending a very stupid patch that simply delegates the same prefix to all clients, whether they actually requested prefix delegation or not. You'll want to compile that with make EXTRA_DEFINES=-DHORRIBLE_HACK_FOR_ALEXANDER Let me know if you have clear ideas about how to do the server side.
