linux red hat 9 : pptpd vpn服务器的配置及说明
公司需要配置一个vpn的服务器，我选择了pptp这个协议，相关的软件如下：
1、kernelmod-0.7.1.tar.gz #MPPE的kernel补丁
2、ppp-2.4.2-b3.i386.rpm #升级PPP
3、pptpd-1.1.4-b4.i386.rpm #pptpd的软件
环境:
OS:red hat 9
在安装系统之后首先安装或升级PPP:
#rpm -qa|grep ppp #查询PPP有没有安装
#rpm -ivh pptpd-1.1.4-b4.i386.rpm #安装PPP
#rpm -Uvh pptpd-1.1.4-b4.i386.rpm #升级PPP

相关配置：
/etc/pptpd.conf pptpd的配置文件
/etc/ppp/options.pptpd 这是选项文件，我把它叫做控制文件
/etc/ppp/chap-secrtes 这是开帐户用的文件
实例：
/etc/pptpd.conf:

# Sample PoPToP configuration file

#
################################################################################

# TAG: speed
#
# Specifies the speed for the PPP daemon to talk at.
#
#speed 115200

# TAG: option
#
# Specifies the location of the PPP options file.
# By default PPP looks in '/etc/ppp/options'
#
option /etc/ppp/options.pptpd

# TAG: stimeout
#
# Specifies timeout (in seconds) on starting ctrl connection
#
# stimeout 10

# TAG: debug
#
# Turns on (more) debugging to syslog
#
debug

# TAG: bcrelay <if>
#
# Turns on broadcast relay to clients from interface <if>
#
#bcrelay eth0
listen 11.1.1.97

# TAG: localip
# TAG: remoteip
#
# Specifies the local and remote IP address ranges.
#
# You can specify single IP addresses seperated by commas or you can
# specify ranges, or both. For example:
#
# 192.168.0.234,192.168.0.245-249,192.168.0.254
#
# IMPORTANT RESTRICTIONS:
#
# 1. No spaces are permitted between commas or within addresses.
#
# 2. If you give more IP addresses than MAX_CONNECTIONS, it will
# start at the beginning of the list and go until it gets
# MAX_CONNECTIONS IPs. Others will be ignored.
#
# 3. No shortcuts in ranges! ie. 234-8 does not mean 234 to 238,
# you must type 234-238 if you mean this.
#
# 4. If you give a single localIP, that's ok - all local IPs will
# be set to the given one. You MUST still give at least one remote
# IP for each simultaneous client.
#
localip 192.168.10.1
remoteip 192.168.10.100-240
netmast 255.255.255.0
# or
#localip 192.168.0.234-238,192.168.0.245
#remoteip 192.168.1.234-238,192.168.1.245

查看内核是否支持Mppe :
#strings ' /usr/sbin/pppd' |grep -i mppe|wc --lines
大于30则支持mppe
加入模块

#modprobe ppp_mppe
出现一些提示说明成功加载

启动pptpd:
service pptpd start
