server 初始化配置 及 VPN的搭建
先给ubuntu用户设置密码
sudo passwd ubuntu
 
更改ssh 允许用户名密码登录
sudo vi /etc/ssh/sshd_config
PasswordAuthentication 改成 yes 
重启ssh 服务
sudo service ssh restart
 
//中文支持
sudo locale-gen zh_CN.UTF-8
//修改时区
sudo dpkg-reconfigure tzdata
//同步时间
sudo ntpdate cn.pool.ntp.org
cn.pool.ntp.org是位于中国的公共NTP服务器
 
vpn 搭建
sudo apt-get install pptpd
 
修改配置文件
sudo vi /etc/pptpd.conf
 
localip 与 remoteip 两行是注释掉的,把注释去掉
值不需要修改,保留默认就好
 
sudo vi /etc/ppp/pptpd-options
去掉 ms-dns两行的注释
并改为 谷歌的dns 服务器
ms-dns 8.8.8.8
ms-dns 8.8.4.4
 
sudo vi /etc/ppp/chap-secrets
添加 username pptpd password *
username 与 password 自己补上，pptpd 和 * 不要动，注意空格
 
sudo service pptpd restart
 
sudo vi /etc/systcl.conf
把net.ipv4.ip_forward=1的注释去掉
执行 sudo sysctl -p
 
允许转发
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
 
关于创建客户端。
linux 
vnp connections --- configuare VPN --- ADD
创建一个point - to -point xxxxxxxxxxxx
填写用户名 密码 domain 
点击Advance 里有个设置一定要勾上 use point-to-point encryption (MPPE) 
 
现在客户端应该能连上, 如果连不上 考虑aws的安全设置(端口没有开放)和pptpd服务没有启动。
 
常用命令

ubuntu   pts/4        2014-07-03 14:12 (182.18.32.162)
强制让一个链接断线
sudo pkill -kill -t pts/3 (别把当前执行命令的用户踢掉了)
 
查看vpn 链接
ifconfig 
显示

sudo kill -9 pid (exp 182754 就会关掉 235的链接)
