pppoe+radius server

[Hernán Freschi]

Hi everyone,
I'm new to this list and I have a question about PPP. I'm trying to
port to BSD what I have already done in Linux, it's a pppoe access
server, like "Project Warta".
On Linux I had a PPP plugin called "radattr.so", which writes a file
named /var/run/radattr.ifacename containing the attr-values returned
by the RADIUS server. When the interface comes up, the script parses
the file and finds the speed limit for the user, for example "Download
= 256".
Is there anything like that plugin for FreeBSD?

Thanks,
Hernan Freschi
