1.你所需要的软件
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
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
wget http://poptop.sourceforge.net/yum/stable/packages/dkms-2.0.17.5-1.noarch.rpm
wget http://poptop.sourceforge.net/yum/stable/packages/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。
rpm -ivh dkms-2.0.17.5-1.noarch.rpm
rpm -ivh kernel_ppp_mppe-1.0.2-3dkms.noarch.rpm
以上二个是为CENTOS加载MPPE[MICROSOFT的加密协议] ..不安装的话就不能使用加密连接
ok后重起你的系统
4。安装pppd
yum install ppp
或者
rpm －Uvh ppp-2.4.2-b3.i386.rpm
5。安装pptpd
(1)使用yum安装
# vim /etc/yum.repos.d/Doylenet.repo
[doylenet]
name=Doylenet custom repository for CentOS
baseurl=http://files.doylenet.net/linux/yum/centos/5/i386/doylenet/
gpgcheck=1
gpgkey=http://files.doylenet.net/linux/yum/centos/RPM-GPG-KEY-rdoyle
enabled=1
# yum update
# yum install pptpd
(2)
rpm －ivh pptpd-1.1.3-4.i386.rpm
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
在最后面添加
localip 10.8.8.1
remoteip 10.8.8.2-245
localip是pptpd的对外服务的ip，也就是客户端需要拨号的ip(这个待测，有人说是VPN服务器地址，究竟是外网ip还是内网ip，等待测试)
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
添加DNS
ms-dns 202.96.209.6
以下是配置说明：
#相当于身份验证时的域，一定要和/etc/ppp/chap-secrets中的内容对应，下面会讲到。
name pptpd
#传输加密。ppp-2.4.2以上的版本只支持MPPE加密，内核模块为 ppp_mppe.o
#拒绝pap身份验证
refuse-pap
#拒绝chap身份验证
refuse-chap
#拒绝mschap身份验证
refuse-mschap
#采用mschap-v2（Microsoft Challenge Handshake Authentication Protocol, Version 2）身份验证方式
require-mschap-v2
#注意在采用mschap-v2身份验证方式时要使用MPPE进行加密
require-mppe-128
#给客户端分配DNS地址和WINS服务器地址
ms-dns 202.99.96.68
#ms-wins 10.0.0.4
#启动ARP代理，如果分配给客户端的IP地址与内网网卡在一个子网就需要启用ARP代理。
Proxyarp
6.3
编辑 /etc/ppp/chap-secrets
添加一个测试用户
第一个test是用户，第二个test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。
6.4
打开防火墙端口
将Linux服务器的1723端口和47端口打开，并打开GRE协议。
/sbin/iptables -A INPUT -p tcp --dport 1723 -j ACCEPT
/sbin/iptables -A INPUT -p tcp --dport 47 -j ACCEPT
/sbin/iptables -A INPUT -p gre -j ACCEPT
iptables -A POSTROUTING -t nat -s 10.8.8.0/24 -o eth0 -j MASQUERADE
即可
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 09:55:17 kdfng pppd[940]: Connection terminated.
Feb 10 09:55:17 kdfng pppd[940]: Exit.
Feb 10 09:55:17 kdfng pptpd[939]: CTRL: Client 192.168.8.53 control connection finished
这样你的pptpd就配置完成了。
检查PPP是否支持MPPE，用以下命令检查PPP是否支持MPPE：
strings '/usr/sbin/pppd' |grep -i mppe | wc --lines
果以上命令输出为“0”则表示不支持；输出为“30”或更大的数字就表示支持。
注意：
如果一直提示619或者800错误查看日志发现
pppd is unable to open the /dev/ppp device. You need to create the /dev/ppp device node by executing the following command as root: mknod /dev/ppp c 108 0
运行
就正常一些了，后面继续
