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
