Nmap
Nmap is a free and open source utility for network discovery,
administration and security auditing. It supports ping scanning
(determine which hosts are up),
many portscanning techniques, version detection (determine service
protocols and application versions listening behind ports), and TCP/IP
fingerprinting (remote host OS or device identification).
Nmap also offers flexible target and port specification,
decoy/stealth scanning, sunRPC scanning, and more.
Features include:
- Host Discovery - Identifying hosts on a network, for
example listing the hosts which respond to pings, or which have a
particular port open
- Port Scanning - Enumerating the open
ports on one or more target hosts. It is a powerful port scanner
- Version Detection - Interrogating listening network
services listening on remote devices to determine the application name
and version number
- OS Detection - Remotely determining the operating system
and some hardware
characteristics of network devices
- Scriptable interaction with the target - using Nmap
Scripting Engine
(NSE) and Lua programming language, customized queries can be made
- Gopher protocol support
- Smart traceroute
