======如何在G1上使用OpenVPN======

本方讲述了如何在G1上使用OpenVPN,前提是你用的Rom已经安装了OpenVPN.

====== 使用命令: ======

  openvpn --config client.conf -auth auth

====== 说明: ======

1.将证书文件放到/data/vpn目录下

2.手动编辑一个auth文件:第一行写证书用户名,第二行写密码,也放到/data/vpn目录下

3.cd 到/data/vpn目录下

4.启动OpenVPN
  openvpn --config client.conf -auth auth
  
如果嫌每次输入这个命令,可以弄一个小脚本,将这行命令扔到一个文件里,比如:
  echo "openvpn --config client.conf -auth auth"  >>vpn
  chmod 777 vpn
  ./vpn
就可以启动OpenVPN了
  
5.如果一切正常,可以查看下G1的IP:

其中tun0就是OpenVPN链接了:
