Use FreeRADIUS for Wi-Fi Authentication (Part 2)

“Though the PEAP authentication protocol doesn’t require client
certificates, you must install a certificate for the Certificate
Authority (CA) on each computer. This is because we’re using a
self-signed certificate for the server rather than purchasing one
signed from a CA that Windows will recognize, such as VeriSign or
GoDaddy.

“You need to get the etc/raddb/certs/ca.der file copied onto all
the computers. You can copy it on a USB flash drive and take it
around to each PC. To copy, open a new terminal and type “su” to
get into root mode, or use an existing one, and run a copy command,
such as “cp /etc/raddb/certs/ca.der /newlocation/certs”.
