Radiusclient is a framework and library for writing RADIUS clients.
The distribution contains a flexible RADIUS aware login replacement, a
command line program to send RADIUS accounting records and a utility to
query the status of a (Merit) RADIUS server. All these programs are based
on a library which lets you develop your own RADIUS aware application
in less than 50 lines of C code. It is highly portable and runs at least
under Linux, a lot of BSD variants and Solaris.
