Linux CentOS PPTP VPN安装教程

pptpd VPN需要内核支持mppe,如果不支持,请联系你的服务商.

首先，在安装之前，需要检测服务器是否支持ppp,
Run the command below to test if your kernel supports MPPE and you should get a return an “ok”:
<font face="Courier New">#modprobe ppp-compress-18 && echo ok<br /></font>FATAL: Could not load /lib/modules/2.6.18-028stab066.10/modules.dep: No such file or directory

还要检测服务器是否开启了tun/tap
#cat /dev/net/tun
cat: /dev/net/tun: File descriptor in bad state 返回这样的信息说明服务器开启了tun/tap

下面开始配置.
先安装ppp和iptables.

yum install -y ppp iptables

如果出现以下情况

[root@mail ~]# yum install -y ppp iptables
Loaded plugins: fastestmirror
