Nmap is a free, open source tool that quickly and efficiently performs ping sweeps, port scanning, service identification, IP address detection, and operating system detection. Nmap has the benefit of scanning a large number of machines in a single session. It’s supported by many operating systems, including Unix, Windows, and Linux.
The state of the port as determined by an nmap scan can be open, filtered, or unfiltered. Open means that the target machine accepts incoming request on that port. Filteredmeans a firewall or network filter is screening the port and preventing nmap from discovering whether it’s open. Unfiltered mean the port is determined to be closed, and no firewall or filter is interfering with the nmap requests.
Nmap supports several types of scans. Table 1 details some of the common scan methods.

Packet capture (or pcap) is a programming interface (API) that can be used to record network traffic. Network analysis programs with a sniffer function use the interface to capture packets at the network interface. Subsequently, the recorded data can be analyzed and further processed using appropriate tools. Pcap is open source and is available for a variety of individual operating systems, for Unix-like systems in the form of the library libpcap, and under Windows in the version WinPcap. The API itself can be integrated directly via C and C ++. Corresponding wrappers are available for Java, .NET or scripting languages.
