network scanning

In the realm of network administration, discovering all the devices connected to a network is crucial for management and security tasks. Netdiscover is an active/passive address reconnaissance tool, highly useful for network administrators looking to identify devices on a local network. In this blog post, we will dive into what Netdiscover is, why it's beneficial, and how to install and use it across different Linux distributions. Netdiscover is an open-source network tool used for detecting network devices on local ethernet networks. It operates primarily in two modes: passive and active scanning mode.

When managing or troubleshooting a network, knowing what devices are connected is essential. This is where arp-scan becomes an invaluable tool. arp-scan is a command-line utility in Linux that allows system administrators to scan a local network to discover and list all devices that respond to ARP (Address Resolution Protocol) requests. The Address Resolution Protocol (ARP) is a key element of IP networking on LANs. ARP translates IP addresses into physical MAC addresses, allowing for the identification of devices on a local network. Essentially, when your computer wants to communicate with another device on the same network, it uses ARP to find out the hardware address of the destination device.
