Description: SuperScan, displayed in Figure 13-5, is a versatile port scanner for Windows 9x/NT/2000 systems. You can scan a range of hosts or individual hosts from a text file. Similarly, you can scan port ranges or select ports from the port setup list. Additionally, SuperScan can be used to perform ping sweeps using the Ping only option. The port list accompanying SuperScan is an excellent reference for associating a port number with a specific service.
Use: Figure 13-5 displays SuperScan's interface. To begin using the tool, enter the start and end IP addresses in the Start and Stop blocks on the left side of the screen. You can enter the IP address of a name server in the Hostname Lookup window for the tool to use to resolve addresses.
The Scan type window offers several options. Check the Resolve hostnames box if you wish to resolve the names, but keep in mind it may take a little longer to perform the scan. The next box, Only scan/show responding ping hosts, is important. If you check this box, the tool will first ping each address and scan only those that respond to ping. This makes the scan proceed faster, but you will miss any hosts that do not respond to ping. If you uncheck this box, the tool will scan each address completely, but the scan will take longer because scans on each nonexistent host will have to time out before the tool advances to the next target. The next set of options includes Ping only, Every port in list, All selected ports in list (which scans each port you have checked in the port list setup), All list ports from (which scans a specified range of the ports from the list), and All ports from (which allows you to input a range of ports).
In the upper right corner, the configuration box contains a Port list setup button. If you click on this button, SuperScan displays a list of ports from which you can choose the ports you wish to scan (see Figure 13-6). If a port you need is not listed, you can add the port. The tool also allows you to save the port list to disk so you can use it again later.
Once you have configured your options and selected the ports you wish to scan, select the Start button. The scan information window just above the Start button shows you the progress of the scanner. The blue window at the bottom of the page displays the output as it is collected.
Benefits: SuperScan is a fast, highly configurable scanner. You can scan individual hosts or ranges for selected ports. The port list setup is convenient so that you don't have to remember the port numbers for every service. SuperScan is a freeware tool and is an excellent choice for a Windows-based scanner.
Con: SuperScan cannot perform stealth scans or any of the more advanced scan features that Nmap offers.
