近来有一个需求要做无线认证的东东。参考了网上很多文档，有用Freeradius+cisco的无线AP的，有用TP-link的，有用华为3Com的，可就是没有D-link的无线路由器的，倒是找到一个用D-link无线网卡的。认证方式有用MD5认证的，有用tls的证书认证的，有用eap的。不过关于用ms-chap认证的写的都不是很详细，致使我在配置过程中走了不少弯路。下面把我的配置简单的写一下，以便下次配置时能更顺利一些。也希望能帮助到一些有同样困惑的朋友。
软件环境：
RHEL AS4 update 6，Freeadius 1.1.7,mysql-4.1.20-2.RHEL4.1.0.1
硬件环境：
D-link的DI-624+A无线路由器
系统自带的有freeradius 1.0.1，但测试时发现不支持MD5认证。因为我配置时参考了一篇网上的使用MD5认证的文章，但系统自带的不支持MD5认证方式，然后就自己安装了freeradius1.1.7。安装很简单，从官方网站上下载源码包，解压，进入解压后的目录，./configure --prefix=/usr/local/freeradius然后make;make install就行了。还要说明一点儿的是，我使用的系统是x86_64的，make时出错，说什么/usr/lib/libgdbm.so不能创建符号链接之类的错误，查了一下，好象是编译环境的问题，没有那么多时间研究怎么解决，就在一台AS3U8,i686的机器上先编译安装了一份儿，然后直接拷到AS4U6上用了，没有发现有什么问题。
mysql用的系统自带的。下面附一下我的几个配置文件，个人感觉只有一个地方是关键点。是它让我走了不少弯路。

}
这里需要去掉几个sql前面的#号,authorize部分的sql一定要打开注释。其它的改动不大。
2.sql.conf，主要更改下面几个地方：
server = "localhost"
login = "mysqlusername"
password = "somepassword"
3.users这个文件，注释掉下面两行
#DEFAULT Auth-Type = System
# Fall-Through = 1
4.clients.conf在结尾处增加：
client yourAPIpaddress {
secret = somepassword
shortname = dlink
}
5.eap.conf这个文件是关键
cat eap.conf |grep -v "#"
eap {
default_eap_type = peap
timer_expire = 60
ignore_unknown_eap_types = no
cisco_accounting_username_bug = no
md5 {
}
leap {
}
tls {
private_key_password = whatever
private_key_file = ${raddbdir}/certs/cert-srv.pem
certificate_file = ${raddbdir}/certs/cert-srv.pem
CA_file = ${raddbdir}/certs/demoCA/cacert.pem
dh_file = ${raddbdir}/certs/dh
random_file = ${raddbdir}/certs/random
fragment_size = 1024
include_length = yes
check_crl = yes
check_cert_issuer = "/C=GB/ST=Berkshire/L=Newbury/O=My Company Ltd"
check_cert_cn = %{User-Name}
cipher_list = "DEFAULT"
}
ttls {
default_eap_type = mschapv2
copy_request_to_tunnel = no
use_tunneled_reply = no
}
peap {
default_eap_type = mschapv2
}
mschapv2 {
}
}
注意第一行更改为peap，然后打开下面的peap的注释。
mysql的没有什么特殊的，参考网上其它文章添加用户就行了。原来我想用md5+secureW2的pap认证，可不清楚是不是我的无线路由不支持，在服务器上用radtest测试md5认证的用户和明码认证的用户都可以通过认证，但一经过无线路由器，在无线客户端上认证就死活通不过。最后参用了ms-chap的认证方式。
6.无线路由器上的配置
安全方式选择WPA，在它下面选择AES（用TKIP的认证方式也是死活不能通过）
然后在下面的802.1x设定中填上radius服务器的IP,端口用默认的1812，密码用clients.conf中设置的secret
7.无线客户端的设置
现在以windows自带的为例，简单说一下：
图一，网络验证的设置，然后点验证，进行图二的设置。
然后点属性，进入下一个页面的设置：见下图。
去掉验证服务器证书前面的勾。然后勾上“启用快速重新边接”。验证方法选“安全密码（EAP-MSCHAP v2)".再点配置，去掉里面的勾。重新连接无线网，会弹出一个认证窗口，在里面输入在服务器上分配的用户名和密码就可以了。
