（待整理）PPTP+FreeRADIUS+MySQL搭建PPTP认证和流量控制

2014/12/2900:29:39 发表评论

源码包软件参考地址：

PopTop: http://poptop.sourceforge.net/

PPPd: http://ppp.samba.org/

FreeRADIUS: http://freeradius.org/

RADIUSClient: http://wiki.freeradius.org/Radiusclient

MySQL: http://www.mysql.com/

本文描述尽可能使用系统自带的软件发行包来搭建VPN，考虑到使用尽可能高版本的PPTP,freeRadius等，选择了CentOS的最新版6.2

1、安装CentOS6.5

为了简化系统，选择最下化安装，然后根据需要安装所需软件包

#yum install mysql mysql-server freeradius* pptp* gcc make

2、配置freeRadius

[root@vpn3-1 ~]# cd /etc/raddb/

[root@vpn3-1 raddb]# cp sites-available/default sites-available/default.sav

[root@vpn3-1 raddb]# vi sites-enabled/default

在所有的unix和files前面加上注释，并去掉所有sql前面的注释。如果要减少日志数量，把 detail注视掉

[root@vpn3-1 raddb]# vi radiusd.conf

去掉$include sql.conf前面的注释。

[root@vpn3-1 raddb]# vi clients.conf

添加NAS信息

#client some.host.org {

# secret = testing123

# shortname = somehost

或

#client 10.10.2.3 {

# secret = testing123

# shortname = localhost2

其中，每一个NAS对应一组，提供的信息有：NAS的IP或域名；加密字符串（Nas配置一致）；accounting用的名字

对应localhost，已有缺省配置。

[root@vpn3-1 raddb]# vi sql.conf

# Connection info:

server = "localhost"

#port = 3306

password = "radpass"

# Database table configuration for everything except Oracle

radius_db = "radius"

以上是缺省值，可根据实际需要修改的是 server、port、login、password。

[root@vpn3-1 raddb]# vi sql/mysql/dialup.conf

取消

sql_user_name = "%{%{Stripped-User-Name}:-%{%{User-Name}:-DEFAULT}}"

				前面的注释，把下一行注释掉。
			
				同时如果需要打开simultanoues-use（控制同时在线用户数）的话需要把simul_query_check取消注释。

3、建立基本数据库：

[root@vpn3-1 raddb]# service mysqld start

初次启动，数据库初始化

并执行了

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h vpn3-1.xxx.com password 'new-password'

[root@vpn3-1 raddb]# mysql -u root -p

mysql> create database radius;

Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on radius.* to radius@localhost identified by "radpass";

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> exit

[root@vpn3-1 raddb]# mysql -uradius -p radius < /etc/raddb/sql/mysql/schema.sql

Enter password:

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Auth-Type',':=','Local');

Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Service-Type',':=','Framed-User');

Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Framed-IP-Address',':=','255.255.255.255');

Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Framed-IP-Netmask',':=','255.255.255.0');

Query OK, 1 row affected (0.00 sec)

#每60秒进行一次流量统计

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Acct-Interim-Interval',':=','60');

Query OK, 1 row affected (0.00 sec)

#最大每月5G流量

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Max-Monthly-Traffic',':=','5368709120');

Query OK, 1 row affected (0.00 sec)

#同一时刻只允许1个用户在线

mysql> INSERT INTO radgroupcheck (groupname,attribute,op,VALUE) VALUES ('user','Simultaneous-Use',':=','1');

Query OK, 1 row affected (0.00 sec)

#限制上传下载流量

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Mikrotik-Rate-Limit',':=','512k/512k');

Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Framed-Protocol',':=','PPP');

Query OK, 1 row affected (0.00 sec)
mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Framed-MTU',':=','1500');

Query OK, 1 row affected (0.00 sec)
mysql> INSERT INTO radgroupreply (groupname,attribute,op,VALUE) VALUES ('user','Framed-Compression',':=','1');

Query OK, 1 row affected (0.00 sec)

mysql> select * from radgroupreply;

+----+-----------+-----------------------+----+-----------------+
| id | groupname | attribute | op | value |
+----+-----------+-----------------------+----+-----------------+
| 1 | user | Auth-Type | := | Local |
| 2 | user | Service-Type | := | Framed-User |
| 3 | user | Framed-IP-Address | := | 255.255.255.255 |
| 4 | user | Framed-IP-Netmask | := | 255.255.255.0 |
| 5 | user | Acct-Interim-Interval | := | 60 |
| 6 | user | Max-Monthly-Traffic | := | 5368709120 |
| 7 | user | Framed-Protocol | := | PPP |
| 8 | user | Framed-MTU | := | 1500 |
| 9 | user | Framed-Compression | := | 1 |
| 10 | user | Mikrotik-Rate-Limit | := | 512k/512k |
+----+-----------+-----------------------+----+-----------------+

10 rows in set (0.00 sec)

以上前四行是PPP用的参数，不用改动，acct-interim-interval是计算流量的间隔（600秒），意味着每隔10分钟记录当前流量。最后一行是每月最大流量，这里是5G（单位是字节）。

输入测试用户信息:

mysql> INSERT INTO radcheck (username,attribute,op,VALUE) VALUES ('test','Cleartext-Password',':=','test111');

Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO radusergroup (username,groupname) VALUES ('test','user');

Query OK, 1 row affected (0.00 sec)

mysql>

用户名与密码必须以明文/NTLM Crypt形式保存，因为MS-CHAPv2不支持MD5保存的密码。

4、测试freeRadius Server：

[root@vpn3-1 raddb]# radtest test test111 localhost 1649 testing123

radclient:: Failed to find IP address for vpn3-1.xxx.com

radclient: Nothing to send.

表明vpn3-1.xxx.com没有ip，编辑/etc/hosts

[root@vpn3-1 raddb]# vi /etc/hosts

添加vpn3-1.xxx.com对应项

[root@vpn3-1 raddb]# radtest test test111 localhost 1649 testing123

Sending Access-Request of id 171 to 127.0.0.1 port 1812

User-Name = "test"

User-Password = "test111"

NAS-IP-Address = 22.19.16.250

NAS-Port = 1649

rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=171, length=44

Service-Type = Framed-User

Framed-IP-Address = 255.255.255.255

Framed-IP-Netmask = 255.255.255.0

Acct-Interim-Interval = 600

[root@vpn3-1 raddb]#

测试成功。

5、添加在认证时检测流量的语句

打开/etc/raddb/sites-enabled/default，找到authorize一节末尾插入

update request {

Group-Name := "%{sql:SELECT groupname FROM radusergroup WHERE \

username='%{User-Name}' ORDER BY priority}"

}

if ("%{sql: SELECT SUM(acctinputoctets+acctoutputoctets)\

FROM radacct \

WHERE username='%{User-Name}' AND \

date_format(acctstarttime, '%Y-%m-%d') >= \

date_format(now(),'%Y-%m-01') AND \

date_format(acctstoptime, '%Y-%m-%d') <= \

last_day(now());}" >= \

"%{sql: SELECT value FROM radgroupreply \

WHERE groupname='%{Group-Name}' AND \

attribute='Max-Monthly-Traffic';}"\

) {

reject

}

由于第三节和本节中有非内置的attribute Max-Monthly-Traffic，所以需要在l/etc/raddb/dictionary里面定义：

ATTRIBUTE Max-Monthly-Traffic 3003 integer

**也可以通过修改/etc/raddb/sql/mysql/counter.conf 和/etc/raddb/sites-enabled/default实现相应功能

在 /etc/raddb/sql/mysql/counter.conf 文件末尾添加如下字段

sqlcounter monthlytrafficcounter {

counter-name = Monthly-Traffic

check-name = Max-Monthly-Traffic

reply-name = Monthly-Traffic-Limit

sqlmod-inst = sql

key = User-Name

reset = monthly

query = "SELECT SUM(acctinputoctets + acctoutputoctets) DIV 1024 FROM radacct \

WHERE UserName='%{%k}' AND UNIX_TIMESTAMP(AcctStartTime) > '%b'"

}

启用流量统计

在 /etc/raddb/sites-enabled/default 文件的 authorize 区块中，添加 monthlytrafficcounter ，在字典文件 /etc/raddb/dictionary 末尾添加如下两行

ATTRIBUTE Max-Monthly-Traffic 3003 integer

ATTRIBUTE Monthly-Traffic-Limit 3004 integer

在数据库里面添加限制字段

INSERT INTO radgroupcheck (groupname,attribute,op,VALUE) VALUES \

('user','Max-Monthly-Traffic',':=','5368709120');

添加到 radgroupcheck 表示针对所有组的生效

由于 Max-Monthly-Traffic 3003 integer 整数型的最大长度为2G，如果限额超过2G,会导致认证失败，所以解决方法就是对查询到的用户的流量，除以 1024，然后对用户的限额也除以1024，这样可以解决问题

**引自介绍freeradius 的一些配置

6、设置radiusclient

centos（RHEL）上没有radiusclient包，为此，添加yum源dag

[root@vpn3-1 ~]#rpm -Uvh http://apt.sw.be/redhat/el6/en/x86_64/dag/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

[root@vpn3-1 ~]# yum install radiusclient-ng*

[root@vpn3-1 etc]# cd /etc/radiusclient-ng/

[root@vpn3-1 radiusclient-ng]# vi radiusclient.conf

修改 authserver 和acctserver

authserver localhost:1812 #用户验证服务器(如果不是本机，请指定IP)（可以为多个，依次尝试）

acctserver localhost:1813 #用户账户记录服务器(如果不是本机，请指定IP)

*****注释掉bindaddr * （77行），pppd提示unrecognized keyword: bindaddr

[root@vpn3-1 radiusclient-ng]# vi /usr/share/radiusclient-ng/dictionary

添加

INCLUDE /usr/share/freeradius/dictionary.merit

INCLUDE /usr/share/freeradius/dictionary.microsoft

****本来想直接使用freeradius-server自带的dictionary，但是，server使用的和client用的不一致，还必须使用client自带的文件，因此上边两行要改写为

INCLUDE /usr/share/radiusclient-ng/dictionary.merit

INCLUDE /usr/share/radiusclient-ng/dictionary.microsoft

其中dictionary.microsoft文件从https://dev.openwrt.org/browser/trunk/openwrt/package/ppp/files/etc/ppp/radius/dictionary.microsoft?rev=940下载

修改server：/etc/radiusclient-ng/servers

最后加上localhost secret（就是FreeRadius的/etc/raddb/clients.conf里面定义的secret ）

7、安装配置pptp

[root@vpn3-1 ~]# rpm -Uvh http://poptop.sourceforge.net/yum/stable/rhel6/pptp-release-current.noarch.rpm

[root@vpn3-1 ~]# yum install pptpd

[root@vpn3-1 ~]# vi /etc/ppp/options.pptpd

将ms-dns设置为本地DNS或 8.8.8.8

ms-dns 8.8.8.8 #客户端首要DNS
ms-dns 8.8.4.4 #客户端次要DNS

末尾处添加

plugin /usr/lib64/pppd/2.4.5/radius.so
plugin /usr/lib64/pppd/2.4.5/radattr.so
radius-config-file /etc/radiusclient-ng/radiusclient.conf

[root@vpn3-1 ~]# vi /etc/pptpd.conf

修改pptpd.conf：

ppp路径改为/usr/sbin/pppd

option路径为/etc/options.pptpd

注释掉logwtmp避免619错误

最后的localip根据需要设置

示例：

localip 202.xxx.16.250 //vpn 服务器地址
remoteip 172.16.36.1-254 //分配给拨号PC的地址

8、测试记录

运行radiusd -X

1）连接测试，提示无法连接，/var/log/message无访问记录，关闭iptbles

2）连接测试，提示鉴定失败，/var/log/message有提示

Jan 22 13:05:19 vpn3-1 pppd[22537]: /etc/radiusclient-ng/radiusclient.conf: line 77: unrecognized keyword:

Jan 22 14:52:33 vpn3-1 pppd[1562]: rc_read_dictionary: invalid type on line 11 of dictionary /usr/share/freeradius/dictionary.microsoft

bindaddr

Jan 22 13:18:07 vpn3-1 pppd[22555]: rc_read_dictionary: couldn't open dictionary /usr/share/radiusclient-ng/dictionary: Permission denied

这是由于server使用的和client用的dictionary文件不一致，还必须使用client自带的文件

3）修改后，再次连接，radius server 反映正常，认证OK，可以建立VPN连接。但是，网络不通。

由于iptables没有启动，应该是该问题导致

4)在测试iptables时，出现了认证无法通过，radiusd -X的诊断信息有Reply-Message = "\r\nYou are already logged in - access denied\r\n\n"，清空了radacct还是没有解决，最后发现：

将/etc/raddb/site-enabled/default中，session段内的radutmp注释

session {
#       radutmp
        #
        # See "Simultaneous Use Checking Queries" in sql.conf
        sql
}

9、iptables配置

编写/etc/rc.local
#
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -F INPUT
iptables -F FORWARD
iptables -t nat -F
iptables -P INPUT ACCEPT
iptables -P FORWARD DROP
iptables -A FORWARD -s 172.16.36.0/24 -j ACCEPT
iptables -A FORWARD -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 1723 -j ACCEPT
iptables -A INPUT -i eth0 -p gre -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -s 172.16.36.0/24 -j SNAT --to 22.xxx.16.250
iptables -A FORWARD -p tcp --syn -s 172.16.36.0/24 -j TCPMSS --set-mss 1356
***注意22.xxx.16.250是服务器IP

或者编辑/etc/sysconfig/iptables

*filter
:INPUT ACCEPT [3603:650757]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A FORWARD -s 172.16.36.0/24 -j ACCEPT
-A FORWARD -i eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -s 172.16.36.0/24 -p tcp -m tcp --tcp-flags FIN,SYN,RST,ACK SYN -j TCPMSS --set-mss 1356
-A OUTPUT -j ACCEPT
COMMIT
*nat
:PREROUTING ACCEPT [153:10779]
:POSTROUTING ACCEPT [4:493]
:OUTPUT ACCEPT [4:493]
-A POSTROUTING -s 172.16.36.0/24 -o eth0 -j SNAT --to-source 22.xxx.16.250
COMMIT
***注意22.xxx.16.250是服务器IP

如果要限制某些IP访问VPN服务器（一般限制内网的人访问VPN），可以在rc.local添加

iptables -A INPUT -s 10.0.0.0/8 -j DROP

或在/etc/sysconfig/iptables中插入对应项

*filter
:INPUT ACCEPT [170:34471]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -s 10.0.0.0/8 -j DROP
-A FORWARD -s 172.16.36.0/24 -j ACCEPT
-A FORWARD -i eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -s 172.16.36.0/24 -p tcp -m tcp --tcp-flags FIN,SYN,RST,ACK SYN -j TCPMSS --set-mss 1356
-A OUTPUT -j ACCEPT
COMMIT
*nat
:PREROUTING ACCEPT [15:1443]
:POSTROUTING ACCEPT [3:377]
:OUTPUT ACCEPT [3:377]
-A POSTROUTING -s 172.16.36.0/24 -o eth0 -j SNAT --to-source 22.xxx.16.250
COMMIT

TroubleShooting

可能存在的错误

异常掉线的用户在daloRadius显示为在线用户

异常掉线的client无法在退出时更新radius.radacct表的acctstoptime，这些client在daloRadius里会被显示为在线用户。使用如下的命令可修复该问题，最好使用cron定期执行该任务。

mysql -uroot -p -e "UPDATE radius.radacct SET acctstoptime = acctstarttime + acctsessiontime WHERE ((UNIX_TIMESTAMP(acctstarttime) + acctsessiontime + 240 - UNIX_TIMESTAMP())<0) AND acctstoptime IS NULL;"

各表名的含义：

修改配置文件/usr/local/etc/raddb/sql.conf
去掉 readclients = yes 前的#号去掉 (100行)
说明:开启数据库nas支持,否则无法限制同一用户登录数。
修改配置文件/usr/local/etc/raddb/sql/mysql/dialup.conf
找到以下内容，将前面的#号去掉(279-282行)
      simul_count_query = "SELECT COUNT(*) \
                           FROM ${acct_table1} \
                           WHERE username = '%{SQL-User-Name}' \
                           AND acctstoptime IS NULL"
说明:开启在线人数查询支持

添加人数控制

编辑/etc/raddb/sql/mysql/dialup.conf
注释sql_user_name = "%{%{Stripped-User-Name}:-%{%{User-Name}:-none}}"
并取消注释下一行
如果需要打开simultanoues-use（控制同时在线用户数）的话需要把simul_count_query取消注释
注意：我这里注释了simul_count_query，但在数据库radgroupcheck表里设定的用户数量限制仍然有效，原因未知

编辑/etc/raddb/dictionary，添加如下两行
ATTRIBUTE Max-Monthly-Traffic 3003 integer
ATTRIBUTE Monthly-Traffic-Limit 3004 integer

编辑/etc/raddb/sites-enabled/default，找到authorize
在该区域的尾部（即“}”前一行）添加一行monthlytrafficcounter

编辑/etc/raddb/sql/mysql/counter.conf，在最后加入
sqlcounter monthlytrafficcounter {
counter-name = Monthly-Traffic
check-name = Max-Monthly-Traffic
reply-name = Monthly-Traffic-Limit
sqlmod-inst = sql
key = User-Name
reset = monthly
query = "SELECT SUM(acctinputoctets + acctoutputoctets) DIV 1048576 FROM radacct WHERE UserName='%{%k}' AND UNIX_TIMESTAMP(AcctStartTime) > '%b'"
}
