Network Monitor

Install Nmap 6.47 on Ubuntu 14.04

Nmap – Network Mapper is a free and open source utility for network discovery and security auditing. Its useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.
