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
