NAME
pnscan - multi threaded port scanning tool
SYNOPSIS
pnscan [ options] [ <CIDR | host-range> <port-range>]
pnscan [ options] [ <port>]
DESCRIPTION
This manual page documents briefly the pnscan command.
pnscan is a tool that can be used to survey TCP network services.
When used with two command line arguments it will scan the indicated network/hosts and
ports. When used without arguments or just one then it will read hostname/IP addresses
from stdin and probe those. The single port/service argument is used as a default if no
port is indicated on stdin
For example, it can be used to survey the installed versions of SSH, FTP, SMTP, Web, IDENT
and possibly other services.
This program implements a multithreaded TCP port scanner. More information and new
relaseses may be found at: http://www.lysator.liu.se/~pen/pnscan
