How To Install zmap on CentOS 7
Introduction

What is zmap
ZMap is an open-source network scanner that enables researchers to easily perform Internet-wide network studies. With a single machine and a well provisioned network uplink, ZMap is capable of performing a complete scan of the IPv4 address space in under 45 minutes, approaching the theoretical limit of gigabit Ethernet. ZMap can be used to study protocol adoption over time, monitor service availability, and help us better understand large systems distributed across the Internet. ========== WARNING ========== While ZMap is a powerful tool for researchers, please keep in mind that by running ZMap, you are potentially scanning the ENTIRE IPv4 address space and some users may not appreciate your scanning. We encourage ZMap users to respect requests to stop scanning and to exclude these networks from ongoing scanning.
