内核最好能升级到2.6
如果你是centos的用户，可以通过yum update来升级到最新的centos4.2
升级内核是为了待会安装一个内核模块增加对mppe的支持。这样才能支持pptp拨号。
pppd ppp拨号服务器
pptpd 在pppd拨号的基础上增加pptpd的支持
freeradius 作拨号用户验证的。
mysql 增加freeradius的数据库支持
2。确定你的内核是否支持mppe
modprobe ppp-compress-18 && echo ok
如果显示ok，那么恭喜，你的内核已经具备了mppe支持。请到第4部分
3。升级内核支持mppe
http://sourceforge.net/project/showfiles.php?group_id=44827
到上面这个网址。下载2个rpm包。
dkms-2.0.6-1.noarch.rpm
kernel_ppp_mppe-1.0.2-3dkms.noarch.rpm
dkms是一个新的软件，能让你在不编译内核的基础上，外挂一些内核的模块。
kernel_ppp_mppe就是mppe支持的内核模块了。
ok后重起你的系统。
4。安装pppd
http://www.samba.org/ppp
在上面的网址下载最新的ppp软件包，我测试的时候是 ppp-2.4.4b1
用最常规的方法，configure，make，make install
由于新版的没有复制范例配置文件，需要用 make install-etcppp 来安装范例配置文件
5。安装pptpd
http://poptop.sourceforge.net/
在上面的网址下载最新的pptpd包，我测试的时候是pptpd-1.2.3
也是最常规的方法 configure，make，make install
6。配置你的pppd和pptpd
pppd的默认配置文件在 /etc/ppp
pptpd的配置文件在 /etc/pptpd.conf
pptpd和pppd的关系好比 pptpd是pppd的外挂一样。
6.1
/etc/pptpd.conf中需要配置的地方只有几个
你首先要确定下面这个
ppp /usr/local/sbin/pppd
他给pptpd指名了pppd的所在
option /etc/ppp/options.pptpd
这个说明了pptpd在ppp下的配置文件
localip 192.168.8.22 remoteip 10.10.110.1-100
localip是pptpd的对外服务的ip，也就是客户端需要拨号的ip
remoteip是拨号服务器分配给拨号用户的ip ，可以用-表示ip范围
6.2
配置/etc/ppp/options.pptpd
为了测试，请打开debug和dump
# Logging # Enable connection debugging facilities. # (see your syslog configuration for where pppd sends to) debug # Print out all the option values which have been set. # (often requested by mailing list to verify options) dump
默认的信息会写在/var/log/messages
6.3
编辑 /etc/ppp/chap-secrets
添加一个测试用户
# Secrets for authentication using CHAP # client server secret IP addresses "iamok" pptpd "iamok" *
第一个iamok是用户，第二个iamok是密码 ，*表示任意ip
pptpd表示和/etc/ppp/options.pptpd中的name 部分的pptpd要匹配，一般不用修改，我们只是
测试以下pptpd是否正常。
7。测试你的pptpd
如果是默认安装，你在任意路径打pptpd就可以了。
如果成功，你就会在
/var/log/messages里面看到
Feb 10 09:51:46 kdfng pptpd[926]: MGR: Manager process started Feb 10 09:51:46 kdfng pptpd[926]: MGR: Maximum of 100 connections available
然后你可以在任意一个win2k系统上建立一个vpn连接，用pptp方式的，用户名用上面设置的，这样你就能拨号了
而且ip就是你在上面所设置的ip
现在复查以下log文件
Feb 10 09:54:53 kdfng pptpd[937]: MGR: Manager process started Feb 10 09:54:53 kdfng pptpd[937]: MGR: Maximum of 100 connections available Feb 10 09:55:06 kdfng pptpd[939]: CTRL: Client 192.168.8.53 control connection started Feb 10 09:55:06 kdfng pptpd[939]: CTRL: Starting call (launching pppd, opening GRE) Feb 10 09:55:06 kdfng pppd[940]: pppd options in effect: Feb 10 09:55:06 kdfng pppd[940]: debug # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: nologfd # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: dump # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: require-mschap-v2 # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: refuse-pap # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: refuse-chap # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: refuse-mschap # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: name pptpd # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: 115200 # (from command line) Feb 10 09:55:06 kdfng pppd[940]: lock # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: local # (from command line) Feb 10 09:55:06 kdfng pppd[940]: ipparam 192.168.8.53 # (from command line) Feb 10 09:55:06 kdfng pppd[940]: 192.168.8.22:10.10.110.1 # (from command line) Feb 10 09:55:06 kdfng pppd[940]: nobsdcomp # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: require-mppe-128 # (from /etc/ppp/options.pptpd) Feb 10 09:55:06 kdfng pppd[940]: pppd 2.4.4b1 started by root, uid 0 Feb 10 09:55:06 kdfng pppd[940]: Using interface ppp0 Feb 10 09:55:06 kdfng pppd[940]: Connect: ppp0 <--> /dev/pts/1 Feb 10 09:55:06 kdfng pptpd[939]: CTRL: Ignored a SET LINK INFO packet with real ACCMs!

这样你的pptpd就配置完成了。
pptpd+radius+mysql 安装攻略（part2 radius部分）
文章作者： i_amok
信息来源：CCF
1。需要软件
freeradius
原先pppd源码目录中的一些关于radius外挂模块的配置文件。
2。安装freeradius的前期准备
安装mysql-devel.i386
yum install mysql-devel.i386
3。安装freeradius
下载源码，我测试的时候是用 freeradius-1.1.0
用指定安装目录的方法安装
代码:
./configure --prefix=/usr/local/freeradius-1.1.0
make
make install
4。配置pppd支持radius
4.1拷贝文件
从pppd的源码目录把下面这个目录复制到/etc/radiusclient/
代码:
cp -R ppp-2.4.4b1/pppd/plugins/radius/etc /etc/radiusclient/
4.2修改options.pptpd中的配置
在/etc/ppp/options.pptpd
中加入
代码:
plugin /usr/local/lib/pppd/2.4.4b1/radius.so
4.3 配置 /etc/radiusclient中的servers和radiusclient.conf
在servers中，你需要增加一个radiusd的地址和密码
代码:
[root@kdfng radiusclient]# cat servers
#Server Name or Client/Server pair Key
#---------------- ---------------
#portmaster.elemental.net hardlyasecret
#portmaster2.elemental.net donttellanyone
localhost netdragon
BT无线网络破解教程
这里localhost表示你的radiusd就在本机，并且访问的密码是netdragon
radiusclient.conf中
代码:
# service. if this fails also a compiled in default is used.
authserver localhost:1812
# RADIUS server to use for accouting requests. All that I
# said for authserver applies, too.
#
acctserver localhost:1813
确认上面也是本地的，默认就是本地，所以一般不需要修改。
同时确保这个文件中radiusclient相关的路径所有的路径都是 /etc/radiusclient 开头的。
5。配置freeradius
cd /usr/local/freeradius-1.1.0/etc/raddb
raddb这个目录就是所有的freeradius配置文件所在了
5.1 修改clients.conf
这里说明一下，所有的nas都是radiusd的client，nas就是那个pptpd，所以这个文件就是配置pptpd的登陆权限的。
代码:
client 127.0.0.1 {
secret = netdragon
shortname = iamok
nastype = other
}
修改127.0.0.1部分为上面的样子。secret就是我们刚才在/etc/radiusclient中servers里设置的那个。这两个要一致
5.2 在users文件的最上面加入一个用户
代码:
ww Auth-Type:= MS-CHAP, User-Password=="ww", Simultaneous-Use:=1
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = 255.255.255.254,
Framed-IP-Netmask = 255.255.255.0
说明一下 ww是用户名
auth-type是验证的类型
第二个ww是密码
Simultaneous-Use是允许这个用户名同时登陆的个数
所有这些都是check属性，要写在第一行
然后第二行开始用tab开头，是服务器返回给radius客户端的（也就是返回给pptpd）时reply属性。
其中ip地址设置为255.255.255.254表示ip地址的分配是由radius客户端决定的，也就是由pptpd决定。
最后一个是子网掩码。
5.3用debug模式运行radiusd
代码:
../../sbin/radiusd -x
你会看到
代码:
Starting - reading configuration files ...
Using deprecated naslist file. Support for this will go away soon.

6。测试
建立一个新的vpn连接
用户名ww密码ww
然后拨号
成功的话，会看到。
代码:
rad_recv: Access-Request packet from host 127.0.0.1:32768, id=214, length=144
Service-Type = Framed-User
Framed-Protocol = PPP思科路由器配置
User-Name = "ww"

rad_recv: Accounting-Request packet from host 127.0.0.1:32768, id=215, length=108
Acct-Session-Id = "43EBFF39048300"

Acct-Status-Type = Start
Service-Type = Framed-User

Calling-Station-Id = "192.168.8.53"
Acct-Authentic = RADIUS
NAS-Port-Type = Async

NAS-Port = 0
Acct-Delay-Time = 0
Sending Accounting-Response of id 215 to 127.0.0.1 port 32768
这样pptp+radius的部分就完成了，下面一部分是对radiusd增加mysql的支持
用ctrl+c退出radius
]pptpd+radius+mysql 安装攻略（part3 mysql部分）
信息来源：CCF
1.需要软件，什么都不需要。
你只要给各mysql的库就好了，库结构在
freeradius源码目录下的/src/modules/rlm_sql/drivers/rlm_sql_mysql/db_mysql.sql
你建立一个数据库就好了，我在我自己的机器上建立了一个名字为radius的数据库
并且导入了这个数据库的结构。
2。配置sql.conf
先回到刚才的freeradius的配置文件目录
代码:
cd /usr/local/freeradius-1.1.0/etc/raddb
vi sql.conf
思科路由器交换机
修改连接信息
代码:
# Connect info
server = "192.168.8.53"
login = "radius"
password = "radius"
# Database table configuration
radius_db = "radius"
去掉下面的simul。。。。前面的#
打开sql的用户同时连接数测试的语句
代码:
# Uncomment simul_count_query to enable simultaneous use checking
simul_count_query = "SELECT COUNT(*) FROM ${acct_table1} WHERE UserName='%{SQL-User-Name}' AND AcctStopTime = 0"
3.配置radiusd.conf
注释掉 authorize {
的files
去掉sql前的注释
注释掉 preacct {
的files
注释掉 accounting {
的radutmp
去掉sql前面的#
注释掉 session{
的radutmp
去掉sql前面的#
去掉 post-auth {
sql前的#
总之就是去掉files模块，开启sql模块
4。在数据库中添加用户
在usergroup中添加一个test用户，组名为vpn
在radgroupcheck中添加一个vpn组，
attribute为Simultaneous-Use
op为:=
value为1
的纪录
在radcheck中添加
username为test
attribute为 User-Password
op为==
value为test
这样就添加了一个用户为test，组为vpn，密码为test
并且所有的组用户的都只能1个用户名登陆一次
5.测试
用debug模式启动radiusd
会看到
代码:
