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
