This section provides a pointer to using a Windows Server instead of Open Source.
Mike Van Opstal of the University of Maryland has written an excellent how-to on using a Windows 2000 as a RADIUS and DHCP server. Rather than duplicate that material here, you can find Mike's how-to at www.cs.umd.edu/~mvanopst/8021x/howto/server.html and a link to it at our site www.wpa-security.org/Windows/server.html.
Adam Sulmicki's how-to can be found at www.missl.cs.umd.edu/wireless/eaptls/ and Raymond McKay's how-to can be found at www.impossiblereflex.com/8021x/eap-tls-HOWTO.htm. Finally, you can find more information about using OpenSSL at the following URL: www.pseudonym.org/ssl/ssl_cook.htm, and in the book by John Viega, Matt Messier, and Pravir Chandra (2002) entitled Network Security with OpenSSL.
