There is a perl implementation, but not a radiusd implementation that is freely available. If you search for +perl +"dynamic dns" on altavista, the reference pops right up: http://simmons.starkville.ms.us/tips/081797/ This is somewhat less than satisfying, in that it requires the ISP to trust the "ppp-up"/"ppp-down" on the client to do the updates at the ISP. But it shows how it can be done. A radiusd implementation is more interesting. I've been trying to convince a number of companies to fund one, since it would want to be applied to all the implementations available so the technology gets widely adopted. The amount of work is small, but the test-bed would require several machines, a terminal server that uses radiusd (and supports reporting "Framed-IP-Address" reply item, or supports acting as a DHCP client, and which provides the "Framed-IP-Address" to the client explicitly). This is a relatively small hack, but is more difficult on FreeBSD because FreeBSD integrates the bind 4.x.x library into libc, and dynamic DNS requires that you run bind 8.x.x (on the internal DNS server, at least). You can compile the bind distribution, and link with -lresolv before -lc, and this will allow you to make the DDNS update calls. One annoying note: Microsoft's "Internet Authentication Server" for NT already supports this: http://irpcomm.microsoft.com/sbs/ispkit/system2.htm (see the second to last bold subheader item).
