This multi-threaded port scanner allows for TCP and UDP scanning at a basic level. Each port specified is checked to see if it is either open, closed, or filtered. IP addresses can be input in several different formats to specify a range (see rules below).

Usage: simple_port_scanner [target_ip_address(es)] [T:|U:][target_port(s)] [options]

Options:

-d

Debug program

<dt>-f <FILE></dt>
<dd>Gather IP addresses from a file</dd>
    	
<dt>-h</dt>
<dd>Display this help text</dd>
         
<dt>-t</dt>
<dd>Perform a traceroute on the target ip(s)</dd>

<dt>-aU</dt>
<dd>Assume that the hosts are up, do not ping</dd>

<dt>-tH <#></dt>
<dd>Specify thread count</dd>

Note: IP Addresses can either be input into the command line or the -f switch can be used

The following rules apply when using * and - to * to represent IP ranges:

1. Only one hyphenated octet per IP glob is allowed and
2. Only asterisks are permitted after a hyphenated octet
