Command line port scanner.
ScanLine is a command-line port scanner for all Windows platforms. It can perform traditional ICMP "pinging", optional additional ICMP TimeStamp scanning, can show host response times and number of hops, do TCP scanning, simple UDP scanning, banner grabbing and hostname resolving. Scanning is performed in a fast highly parallel fashion without resorting to using multiple threads. It can handle huge numbers and ranges of IP addresses without a problem.
