Method Detail

processRequest

public void processRequest(RadiusPacket p)
                    throws RadiusException

Specified by:

processRequest in class RadiusAuthenticator

Parameters:

p - The RadiusPacket to be processed

Throws:

RadiusException

See Also:

RadiusAuthenticator.processRequest(net.jradius.packet.RadiusPacket)

processChallenge

public void processChallenge(RadiusPacket p,
                             RadiusPacket r)
                      throws RadiusException,
                             NoSuchAlgorithmException

EAP requires a challenge/response. The request packet is reset with a new RADIUS identifier and the EAP-Message is encoded.

Overrides:

processChallenge in class RadiusAuthenticator

Parameters:

p - The original AccessRequest RadiusPacket

r - The AccessChallenge packet

Throws:

NoSuchAlgorithmException

RadiusException

See Also:

RadiusAuthenticator.processChallenge(net.jradius.packet.RadiusPacket, net.jradius.packet.RadiusPacket)
