在ubuntu server 11.04上安装pptpd的记录

之前vps上装的是centos系统，用ubuntu用习惯了，centos的yum真心用的不习惯，干脆一咬牙，换ubuntu

首先，先吧之前centos上装pptpd的脚本打开，检查一下主要设置，然后用ubuntu的方式安装相应程序，最后整理脚本如下：

01
#!/bin/bash
02

03
IP=公网IP
04
user=vpn
05
pass=`openssl rand 6 -base64`
06
if [ "$1" != "" ]
07
then pass=$1
08
fi
09

10
apt-get purge pptpd ppp
11
iptables --flush POSTROUTING --table nat
12
iptables --flush FORWARD
13
rm -rf /etc/pptpd.conf
14
rm -rf /etc/ppp
15

16
apt-get install ppp pptpd
17

18
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
19

20
sed -i "s/exit 0/#exit 0/g" /etc/rc.local
21
echo "mknod /dev/ppp c 108 0" >> /etc/rc.local
22
echo "iptables -t nat -A POSTROUTING -s 172.16.99.0/24 -j SNAT --to-source $IP" >> /etc/rc.local
23
echo "iptables -A FORWARD -p tcp --syn -s 172.16.99.0/24 -j TCPMSS --set-mss 1356" >> /etc/rc.local
24
echo "exit 0" >> /etc/rc.local
25

26
echo "localip 172.16.99.1" >> /etc/pptpd.conf
27
echo "remoteip 172.16.99.2-254" >> /etc/pptpd.conf
28

29
echo "ms-dns 8.8.8.8" >> /etc/ppp/pptpd-options
30
echo "ms-dns 8.8.4.4" >> /etc/ppp/pptpd-options
31
sed -i "s/require-mppe-128/#require-mppe-128/g" /etc/ppp/pptpd-options
32

33
echo "${user} pptpd ${pass} *" >> /etc/ppp/chap-secrets
34

35
echo "VPN service is installed, your VPN username is ${user}, VPN password is ${pass}"
执行完脚本，然后重启，就可以了
