dnsmasq-dhcp v1.0.2
dnsmasq-dhcp
A library to start and stop a lightweight DHCP server based on dnsmasq. This library does not use any config files, it only passes command line arguments. So you can start as many instances of dnsmasq as you have interfaces.
Installation
npm i dnsmasq-dhcpUsage
const DHCP = require('dnsmasq-dhcp');
let dhcpServer = new DHCP(options);
dhcpServer.start(result => {
console.log(`Server started successfully: ${result} pid: ${dhcpServer.pid}`);
}).catch(err => {
console.error(`Server failed to start: "${err.result.stderr}", errorCode=${err.result.code}`);
