sudo apt-get install -y libpcap-devLibpcap is already installed
npm install profinetdcpconst { listInterfaces, dcpIdentify, LinkStatus } = require('profinetdcp')
listInterfaces().then((list) => {
const interfaces = list.filter((intf) => !intf.isLoopback && intf.status == LinkStatus.Up)
if (interfaces.length > 0) {
console.log(`Found ${interfaces.length} network interfaces with link status "up"`)
console.log('---------------------------------------------------------------------')
console.log(interfaces)
console.log('---------------------------------------------------------------------')
console.log('Sending DCP identify requests ...')
interfaces.forEach((intf) => {
dcpIdentify(intf).then((hosts) => {
if (hosts.length > 0) {
console.log(`Hosts found on interface ${intf.name}`)
console.log(hosts)
} else {
console.log(`No hosts found on interface ${intf.name}`)
}
}).catch((err) => {
console.log(`Failed to indentify hosts on interface ${intf.name}`)
console.log(err.message)
})
})
} else {
console.log(`No network interfaces found with link status "up"`)
}
