Centos 6 PPTPD/L2TP/IPSec VPN一键安装包

一、一键安装PPTPD VPN

本教程适用于Openv VPS、Xen VPS或者KVM VPS。

1.首先运行如下命令:

cat/dev/net/tun

返回的必须是:

cat: /dev/net/tun: File descriptor in bad state

运行:

cat/dev/ppp

返回的必须是:

cat: /dev/ppp: No such device or address

如果上面返回的不是这两个结果的话,请与VPS客服联系开通ppp和tun权限.

2. 下载vpn(CentOS6专用)一键安装包

wget /shell/vpn_

chmoda+x vpn_

下载vpn__.zip
