demo 如下;
/*
*Linux 环境下获取网络接口信息
*/
//导入os模块
var os = require("os");
//获取系统的网络接口信息
var netInfo = os.networkInterfaces();
//ip地址
var ip = netInfo.eth0[0].address;
//子网掩码
var netMask = netInfo.eth0[0].netmask;
//协议族
var family = netInfo.eth0[0].family;
//Mac地址
var macAddr = netInfo.eth0[0].mac;
//验证
console.log("IP:"+ip);
console.log("NetMask:"+netMask);
console.log("Family:"+family);
console.log("Mac:"++macAddr);
