FreeRADIUS Server (Radius protocol server)
The FreeRADIUS Server is a daemon for unix and unix like operating systems
which allows one to set up a radius protocol server, which can be used for
Authentication and Accounting various types of network access. To use the
server, you also need a correctly setup client which will talk to it,
including terminal servers, Ethernet Switches, Wireless Access Points or a
PC with appropriate software which emulates it (PortSlave, radiusclient etc).
See README.SLACKWARE (which is also installed with the package docs) for
setup, configuration, and usage hints.
