linux下pptp服务器配置

pptp服务器配置与管理

一、      pptpd的安装
1.         所需软件为：
（下载地址：
http://sourceforge.net/project/showfiles.php?group_id=44827
)
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 –Fvh 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
proxyarp
auth
mtu 1450
nobsdcomp
require-mschap-v2
#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}

/sbin/ifconfig $1 mtu 1446

#[ -x /etc/ppp/login.sh ] && /etc/ppp/login.sh "$@"
[ -x /etc/ppp/ip-up.local ] && /etc/ppp/ip-up.local "$@"

exit 0
8.         /etc/ppp/chat-secrets内容如下：
# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
“test”  pptpserver       “dfd&890”  192.168.x.x
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 –n100 /etc/ppp/userlog
