I always intersted in build services in my own VPS. specially things like a server can help me free browser the internet. But sometimes the connection between my own pc and the vps server are not quite good. So things not always go luck.

I find out openvpn is quite useful these days. So I’m thinking I will build one of my own. I picked one of my VPS for the test. It was installed with Ubuntu 14.04 and has 512MB memory. Here are the steps of how I did it:

1. 安装server

   # On CentOS 6 x64:
   rpm -i http://poptop.sourceforge.net/yum/stable/rhel6/pptp-release-current.noarch.rpm
   yum -y install pptpd
   # On Ubuntu 12.10 x64:
   apt-get install pptpd
   

2. 编辑 /etc/pptpd.conf 添加以下行:

    localip 10.0.0.1
    remoteip 10.0.0.100-200
   

localip本机ip(vpn的服务器ip), remoteip-分配给客户端的ip, 应该处于同一网段

3. 添加pptp用户名和密码到 /etc/ppp/chap-secrets :

    #client server secret IP
    user1 pptpd 24odfjafdi34 *
    user2 pptpd 3f3faf3fsdfI *
    #Where client is the username, server is type of service – pptpd for our example, secret is the password, and IP addresses specifies which IP address may authenticate. By setting ‘*’ in IP addresses field, you specify that you would accept username/password pair for any IP.  
   

4. 添加DNS服务器地址到 /etc/ppp/pptpd-options:
