Read and write the linux /etc/network/interfaces file to check and change network connectivity.
npm install linux-interfaces-configThis module is intended for use on embedded linux systems that require configuring the network interfaces and retain this configuration after system reboot.
Currently only Debian and other /etc/network/interfaces file format compatible platforms can be managed with this module.
Node >= 6
Comments and unknown options are ignored (and lost if using a full read().then(write) cycle)
No special attempt to prevent code injection on write()
Although there are some packages published to achieve this by reading and writing the /etc/network/interfaces file, these are incomplete (only offering writing but not reading), or require special permissions to execute command dependencies.
The 'linux-interfaces-config' module is able to parse and write this configuration file with just making use of the standard Node.js library to get I/O access to the file.
npm install --save linux-interfaces-config
Setup
const interfacesConfig = require("linux-interfaces-config")();
You can set a different interfaces file to read/write:
const interfacesConfig = require("linux-interfaces-config")("/path/to/interfaces/file");
Or even change it on runtime:
interfacesConfig.setInputFile("/path/to/interfaces/file");
Read interfaces configuration
interfacesConfig.read().then(console.log);
Write interfaces configuration
interfacesConfig.write({
eth0: {
auto: true,
hotplug: true,
ip4: { config: 'static',
address: '192.168.1.111',
netmask: '255.255.255.0',
gateway: '192.168.1.1',
dnsNameservers: ['8.8.8.8', '8.8.8.9']
}
},
wlan0: {
auto: true,
hotplug: true,
ip4: {
config: 'dhcp',
// WPA protected Wi-Fi configuration
wpaSsid: 'MY_WIFI_NAME',
wpaPsk: 'WIFI-PASSWORD'
},
ip6: { config: 'dhcp' }
}
})
.then(bytes=>console.log());
``When configuring a Wi-Fi with WPA security you might wish to use the PSK HASH instead of the plain password.
