eapol_test is a program that links together the same EAP peer implementation that wpa_supplicant is using and the RADIUS authentication
client code from hostapd. In addition, it has minimal glue code to combine these two components in similar ways to IEEE 802.1X/EAPOL
Authenticator state machines. In other words, it integrates IEEE 802.1X Authenticator (normally, an access point) and IEEE 802.1X Suppli-
cant (normally, a wireless client) together to generate a single program that can be used to test EAP methods without having to setup an
access point and a wireless client.
The main uses for eapol_test are in interoperability testing of EAP methods against RADIUS servers and in development testing for new EAP
methods. It can be easily used to automate EAP testing for interoperability and regression since the program can be run from shell scripts
without require additional test components apart from a RADIUS server. For example, the automated EAP tests described in eap_testing.txt
are implemented with eapol_test. Similarly, eapol_test could be used to implement an automated regression test suite for a RADIUS authenti-
As an example:
eapol_test -ctest.conf -a127.0.0.1 -p1812 -ssecret -r1
tries to complete EAP authentication based on the network configuration from test.conf against the RADIUS server running on the local host.
A re-authentication is triggered to test fast re-authentication. The configuration file uses the same format for network blocks as wpa_sup-
-c configuration file path
A configuration to use. The configuration should use the same format for network blocks as wpa_supplicant.
-a AS address
IP address of the authentication server. The default is '127.0.0.1'.
-A client address
IP address of the client. The default is to select an address automatically.
-p AS port
UDP port of the authentication server. The default is '1812'.
-s AS secret
Shared secret with the authentication server. The default is 'radius'.
Number of reauthentications.
Timeout in seconds. The default is 30.
RADIUS Connect-Info. The default is 'CONNECT 11Mbps 802.11b'.
-M mac address
Client MAC address (Calling-Station-Id). The default is '02:00:00:00:00:01'.
Location to write out server certificate.
-N attr spec
Send arbitrary attribute specific by attr_id:syntax:value, or attr_id alone. attr_id should be the numeric ID of the attribute, and
syntax should be one of 's' (string), 'd' (integer), or 'x' (octet string). The value is the attribute value to send. When attr_id
is given alone, NULL is used as the attribute value. Multiple attributes can be specified by using the option several times.
-n Indicates that no MPPE keys are expected.
-W Wait for a control interface monitor before starting.
-S Save configuration after authentication.
