Ubuntu下freeradius的EAP-MD5，PEAPv0/EAP-MSCHAPv2，EAP-TTLS/MD5，EAP-TTLS/MSCHAPv2方式认证(基于mysql)

基于freeradius+mysql，今天验证下freeradius的EAP认证：1.EAP-MD5；2.EAP-PEAP

一、EAP-MD5方式认证

1.修改配置文件

(1)/usr/local/etc/raddb/sites-available/default

去掉eap前面的#

(2)/usr/local/etc/raddb/eap.conf

确认default_eap_type=md5

2.在数据库中加入Auth-Type为EAP的测试账号

#mysql -u root -p
Enter password:456456
mysql> use freeradius;
mysql> insert into radgroupreply (groupname,attribute,op,value) values ('eap','Auth-Type',':=','EAP');
mysql> insert into radgroupreply (groupname,attribute,op,value) values ('eap','Service-Type',':=','Framed-User');
mysql> insert into radgroupreply (groupname,attribute,op,value) values ('eap','Framed-IP-Address',':=','255.255.255.255');
mysql> insert into radgroupreply (groupname,attribute,op,value) values ('eap','Framed-IP-Netmask',':=','255.255.255.0');
mysql> insert into radcheck (username,attribute,op,value) values ('eap','User-Password',':=','eap');
mysql> insert into radusergroup (username,groupname) values ('eap','eap');
mysql> insert into radreply (username,attribute,op,value) values ('eap','Reply-Message',':=','eap OK!');

3.开始测试

#radiusd -X

#(echo "User-Name = \"eap\""; echo "Cleartext-Password = \"eap\""; echo "EAP-Code = \"Response\""; echo "EAP-Id = 210"; echo "EAP-Type-Identity = \"eap\""; echo "Message-Authenticator = 0x00";) | radeapclient -x localhost auth testing123

	EAP-Id = 211
	EAP-Code = Success

二、PEAPv0/EAP-MSCHAPv2方式认证

1.安装测试工具eapol_test

#cd /usr/local/src/
#wget http://hostap.epitest.fi/releases/wpa_supplicant-0.6.9.tar.gz
#tar –xzvf wpa_supplicant-0.6.9.tar.gz
#cd wpa_supplicant-0.6.9/wpa_supplicant/
#cp defconfig .config
#make eapol_test
#cp eapol_test /usr/local/bin/

2.修改配置文件

(1)/usr/local/etc/raddb/sites-available/default

去掉eap前面的#

(2)/usr/local/etc/raddb/eap.conf

确认default_eap_type=peap

3.查看证书是否存在

#ls /usr/local/etc/raddb/certs/*.pem
正常 列表中含有ca.pem

若没有ca.pem文件，则执行以下命令：
#/usr/local/etc/raddb/certs/bootstrap

4.创建测试配置文件 ~/peap.test

#~/peap.test

network={　　　　　　//注意："="前后无空格
	eap=PEAP
	eapol_flags=0
	key_mgmt=IEEE8021X
	identity="eap"　　//注意：该测试账号是之前用sql建立在数据库中的，所以可以直接使用
	password="eap"
	ca_cert="/usr/local/etc/raddb/certs/ca.pem"
	phase2="auth=MSCHAPV2"
	anonymous_identity="anonymous"
}

5.开始测试

#radiusd -X

#eapol_test -c peap.test -s testing123　　//peap.test在~/目录下，所以该命令也要在~/目录下进行。需保持一致。

eapol_sm_cb: success=1

三、EAP-TTLS/MD5方式认证 

1.修改配置文件

(1)/usr/local/etc/raddb/sites-available/default

去掉eap前面的#

(2)/usr/local/etc/raddb/eap.conf

确认default_eap_type=ttls

2.创建测试配置文件 ~/ttlsmd5.test

~/ttlsmd5.test

network={
	eap=TTLS
	ssid="test"　　//可更改
	key_mgmt=WPA-EAP
	identity="eap"
	password="eap"
	ca_cert="/usr/local/etc/raddb/certs/ca.pem"
	phase2="auth=MD5"
	anonymous_identity="anonymous"　　//可更改
}

3.开始测试

#radiusd -X

#eapol_test -c ttlsmd5.test -s testing123

eapol_sm_cb: success=1
EAPOL: Successfully fetched key (len=32)
PMK from EAPOL – hexdump(len=32): 91 b2 66 fb da ff bd 7d 95 91 2a c5 82 a8 86 bb 18 14 ac 9f 30 e4 7e 21 9f 28 b8 00 35 62 ff f2
EAP: deinitialize previously used EAP method (21, TTLS) at EAP deinit
ENGINE: engine deinit
MPPE keys OK: 1  mismatch: 0
SUCCESS

四、EAP-TTLS/MSCHAPv2方式认证 

1.修改配置文件

(1)/usr/local/etc/raddb/sites-available/default

去掉eap前面的#

(2)/usr/local/etc/raddb/eap.conf

确认default_eap_type=ttls

2.创建测试配置文件 ~/ttlsmschapv2.test

~/ttlsmschapv2.test

network={
	eap=TTLS
	ssid="test"　　//可更改
	key_mgmt=WPA-EAP
	identity="eap"
	password="eap"
	ca_cert="/usr/local/etc/raddb/certs/ca.pem"
	phase2="auth=MSCHAPV2"
	anonymous_identity="anonymous"　　//可更改
}

3.开始测试

#radiusd -X

#eapol_test -c ttlsmschapv2.test -s testing123

eapol_sm_cb: success=1
EAPOL: Successfully fetched key (len=32)
PMK from EAPOL – hexdump(len=32): 91 b2 66 fb da ff bd 7d 95 91 2a c5 82 a8 86 bb 18 14 ac 9f 30 e4 7e 21 9f 28 b8 00 35 62 ff f2
