 Scanning Tools
Nmap. Is a utility for port scanning large networks, although it works fine for single hosts. You can scan different protocols (UDP, TCP, ICMP, etc.). Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings. Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, and output to machine parseable or human readable log files.
