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:

OPTIONS

   -h     Show summary of options.

   -v     Be verbose.

   -V     Print version.

   -d     Print internal debugging info.

   -s     Lookup and  print  hostnames.  This  will  slow  down  the  scan
          considerably.

   -S     Enable  shutdown  mode.  With  this  enabled  pnscan  will  call
          shutdown(2) with an argument of 1 in order to half-close the TCP
          connection  after any -w/-W arguments has been transmitted.  The
          default is to wait for the remote party to close its  end  first
          (or until enough bytes has been received).

   -l     Line  oriented  output.  This option will cause pnscan to try to
          locate the beginning of a line when a  match  (-r/-R)  has  been
          found,  and  only  print  up  to the last byte/character on that
          line.

   -w<string>
          Request string to send. Please  note  that  you  must  send  any
          needed  CR/LF  characters  as  needed  by the protocol since the
          string specified is sent as is (after escape characters has been
          decoded).

   -r<string>
          Response string to look for.

   -W<hex list>
          Hex coded request string to send.

   -R<hex list>
          Hex coded response string to look for.

   -L<length>
          Max bytes of response to print.

   -t<msecs>
          Connect/Write/Read timeout.

   -n<workers>
          Maximum concurrent worker threads to start.
