Using DHCP for Radius on a Cable Modem Plant

[John Alcock]

Morning,

Has anyone use freeradius and the built-in dhcp server in freeradius for a
small cable modem plant?

I am using LDAP for the authentication part and it works.

Radius just seems like a much cleaner solution.

So, the idea I have in mind is using freeradius for authentication and go
ahead and use it for DHCP.  I will use a SQL database backend to keep track
of users.

So, my question has to do with documentation.  Most of seems to be dealing
with version 2, and the main page says.. hey.. do not use version 2 configs
as a starting space.

Also, documentation seems weak on the new DHCP options.

The way I figure it, if I am going to complain about documentation or lack
thereof, I just need to write some documentation and submit to the group.

That being said, some directions in the right direction would help me get
started. I have seen documentation on each of the separate items below, but
not much in tieing it all together.

Platform will be Linux running a standard LAMP installation.

SQL database (mysql, postgress, I do not care) to keep track of
information, specifically the MAC address which will be used for
authentication.

DHCP? Should I use the DHCP built into Radius?  Or outside DHCP server.  I
kind like the idea of allowing Radius handling it all.

So. At the end, I guess I am looking for some general advice on best
practices of setting this up.

Once I get an overview setup, then I can start working on specifics.
