pptp服务器配置与管理
1. 所需软件为：
（下载地址：
[url]http://sourceforge.net/project/showfiles.php?group_id=44827[/url])
dkms- 2.0.6 -1.noarch.rpm
kernel_ppp_mppe- 1.0.2 -3dkms.noarch.rpm
kernelmod- 0.7.1 .tar.gz
ppp- 2.4.3 -5.fc4.i386.rpm
（用
ppp-2.4.4b1
更稳定）
pptpd- 1.3.1 -0.i386.rpm
2. 升级内枋模块
首先查看是否已经支持
mppe
功能：
modprobe ppp-compress-18 && echo ok
如果显示
ok
，那么内核已经具备了
mppe
支持。如果不支持，需安装：
dkms- 2.0.6 -1.noarch.rpm
kernel_ppp_mppe- 1.0.2 -3dkms.noarch.rpm
对于低版本的内核是必须安装
kernelmod- 0.7.1 .tar.gz(
需要内核源代码
)
3. 安装ppp
在上面的网址下载最新的
ppp
软件包，源包用最常规的方法，
configure
，
make
，
make install
。注意：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。一般可用
rpm
软件包：
rpm �CFvh ppp- 2.4.3 -5.fc4.i386.rpm
4. 安装pptpd
在上面的网址下载最新的
pptp
软件包，源包用最常规的方法，
configure
，
make
，
make install
。一般采用
pptp
软件包：
pptpd- 1.3.1 -0.i386.rpm
5. /etc/pptp.conf内容如下：
ppp /usr/local/sbin/pppd
option /etc/ppp/options.pptpd
bcrelay eth0
#listen 0.0.0 .0
localip 192.168.x.x
remoteip 192.168.x.1-254
netmast 255.255.255.0
6. /etc/ppp/options.pptpd内容如下：
lock
dump
logfd 2
logfile /var/log/pptpd.log
name pptpserver

#require-mppe-128
require-mppe
ipparam options.pptpd
ms-dns 192.168.x.x
ms-dns 202.86.252.254
7. /etc/ppp/ip-up内容如下：
#!/bin/bash
# This file should not be modified -- make local changes to
# /etc/ppp/ip-up.local instead
PATH=/sbin:/usr/sbin:/bin:/usr/bin
export PATH
LOGDEVICE=$6
REALDEVICE=$1
[ -f /etc/sysconfig/network-scripts/ifcfg-${LOGDEVICE} ] && /etc/sysconfig/network-scripts/ifup-post ifcfg-${LOGDEVICE}
/etc/ppp/ip-up.ipv6to4 ${LOGDEVICE}

9. 略二、 pptp服务器管理1. 新建用户
Vi /etc/ppp/chat-secrets
增加一条即可，并指定
IP
2. 查看登录日志
tail �Cn100 /etc/ppp/userlog
