Version 2.0 adds SYN scanning capabilities and much more:

• Added option -s for SYN scan.
• Scanning made faster thanks to SYN scan
• Added even more default ports
• Improved error handler for SYN scan
• Improved text output
• Fixed minor bugs

A new branch of the program has been created to support SYN scan. SYN scan was necessary because under some circumstances of heavy load, the TCP Connect scan can hang routers. SYN scan is multithreaded and uses the standard library pcap on Unix/Linux operating systems. Please be aware that SYN scan requires a higher level of authorization, if compared to connect sockets: in Unix/Linux pscan requires root privilege. In some operating systems, SYN scan is performed using connectionless “raw” sockets, therefore the usage of pscan is subject to possible restriction to the usage of raw sockets in such operating systems.

With SYN scan, option -w is not used because the program does not use connected sockets, so it doesn’t have to loop reading a socket until the timeout is reached. The receive function doesn’t have to poll over a number of sockets, but simply reads the packets passing through the network card, for all ports, and displays the message of “open port” when the packet coming from the remote IP contains the information that the remote port is open. For the same reason, options -a and -n are not used. The first one because packets sent to closed ports are simply not being replied to, so they cannot be counted; the second one because the function that reads packets is one, and performs this by reading packets from the network card, not from multiple sockets.

This is another tool that has been around for a long time and I’ve been using it for years since it’s earliest versions, oddly however I’ve never posted about it.

So here it for the few of you that haven’t heard of it, probably the best port scanner on the Windows platform, very fast and compact and has good banner grabbing functionality.

SuperScan 4 is an update of the highly popular Windows port scanning tool, SuperScan.

Windows XP Service Pack 2 has removed raw sockets support which now limits SuperScan and many other network scanning tools. Some functionality can be restored by running the following at the Windows command prompt before starting SuperScan:

net stop SharedAccess

Same goes if you’re using nmap for Windows.

Features

Here are some of the new features in this version.
