luftreich / linux上用strongswan搭建ikev2协议vpn.md
Last active August 29, 2015 14:21 — forked from losisli/linux上用strongswan搭建ikev2协议vpn.md

平台：DigitalOcean VPS ubuntu14.04 x64, strongswan5.2.2 运行以下命令请使用root权限

一：安装strongswan

由于ubuntu软件仓库中strongswan版本较低，因此从官网源码编译安装

apt-get install build-essential     #编译环境
aptitude install libgmp10 libgmp3-dev libssl-dev pkg-config libpcsclite-dev libpam0g-dev     #编译所需要的软件

dnsmasq的配置文件由/etc/config/dhcp决定 ####禁用 dnsmasq 的 DNS 功能 在该文件 config dnsmasq下添加

option port 54

如果你的 WAN 口是 PPPOE 等方式连接,而且系统日志中有 DHCP packet received on eth0.2 which has no address 就再添加

Since this is on Hacker News and reddit...

  • No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is written in BSD mandoc.
