centos上的安裝和調試freeradius

centos上的安裝和調試freeradius

1、使用yum安裝即可，確定安裝的是freeradius2，而不是1。如果以前又freeradius，先卸載
yum remove freeradius
安裝
yum install freeradius2
yum install freeradius2-utils//這個含radtest，用戶測試

默認freeradius是使用files方式認證用戶，如果不使用數據庫，到此安裝就搞定了
2、安裝完成後就修改配置文件。
vi /etc/raddb/users
找到steve，注釋去掉，將steve改成你的用戶名。可以建立多個用戶，如下：
dalon Cleartext-Password := "testing"
test Cleartext-Password := "testing123"
3、 測試
可執行文件為 /usr/sbin/radius
/usr/sbin/radius -X //debug模式運行，可以看到詳細過程。
radtest 測試server是否能響應：
radtest test testing localhost 0 testing123
test和testing分別為用戶名和密鑰，對於配置文件users裡面的內容。
localhost為配置文件clients.conf中的內容，默認針對localhost密鑰為testing123
0 意思為NAS-PORT 0，默認為0，所以不用配置。見文件 /etc/raddb/radiusd.conf中配置，如下：
listen {
ipaddr = * //監聽IPV4所有地址
# ipv6addr = ::
port = 0 //nas-port
type = acct
# interface = eth0
# clients = per_socket_clients
}
測試正確的結果如下（下面是測試IPV6）：
[root@CentOS~]# radtest -6 test test123 ::1 0 testing123
Sending Access-Request of id 44 to ::1 port 1812
User-Name = "test"
User-Password = "test123"
NAS-IPv6-Address = ::1
NAS-Port = 0
Message-Authenticator = 0x00000000000000000000000000000000
rad_recv: Access-Accept packet from host ::1 port 1812, id=44, length=20
4、將服務器改成監聽IPV6
需要修改文件
a) /etc/raddb/radiusd.conf
將兩個listen {}中 ipaddr = *注掉，ipv6addr = :: 取消注釋
b) /etc/raddb/clients.conf
將localhost中的監聽地址改成ipv6的，如下：
client localhost {
ipv6addr = ::1# any.::1 == localhost

建立一組client（下面的例子是3000::/64網段為例，也可以使用::/0）:
client 3000::/64 {
secret = testing123
shortname = ipv6client //為區別名，和別的組不一樣即可
}

5. 驗證通過的debug信息：
rad_recv: Access-Request packet from host 3000::abcd port 60378, id=232, length=45
User-Name = "dalon"
User-Password = "testing"
