ScanLine

ScanLine from Foundstone is arguably the fastest, most robust port-scanning tool ever built. The tool has a myriad of options, but one of its most valuable features is its ability
to scan very large ranges quickly and to include both TCP and UDP scanning in a single
run of the product. Take a look at this example:
C:\ >sl -t 21,22,23,25 -u 53,137,138 192.168.0.1
