This is the second incarnation of the scanner, brought about by a system crash and the loss of the sourcecode for the original. seeing as i was gonna take some time to re-write it, I decided to update it aswell.
In the new version i've added the ability to alter the number of sockets to use for scanning
as although more sockets means generally more speed, the network / dialup u use may be hindered by higher socket usage..
Also introduced is the timeout length, so for when scanning on an internal network you can set the timeout to it's lowest setting for maximum speed, but on slower connections like on the internet, the timeout interval can be increased for maximum accuracy, regardless of local network load..
Another new feature is the Telnet to port, which mainly has a time and effort saving motive
Ok, down to the nitty gritty, the rest of this document is a description of how to use the portscanner....
First start by identifying the "Address" of the target to be scanned, this address can be a hostname (eg www.microsoft.com) or an dotted IP (eg 195.241.198.3) and entering it into the Hostname/IP box on the open ports tab and the required range of ports into the other two boxes provided.
Select the Config tab and if needed, alter the number of sockets to use slider so it shows the required value. generally speaking, 80 to 120 are the best values in most situations. Also set teh required timeout on the slider below, the best values depend on what type of network you will be scanning over, but 4000ms is good for most networks and is the defailt setting.
Return to the open ports tab and click on the start scanning button.
In the box will be displayed how may sockets you have used to scan and any open ports that are found along with their default usage descriptions if known.
On the Data Recieved tab u can see any data that has been returned by any open ports, this is particularly useful if the port is unknown as any data returned might be useful in identifying it's purpose.
When the scan has ended or been terminated by pressing the Stop Scanning button, there are 2 things we can do with the data found, we can save it, by clicking the "save scan data to textfile button and creating a file with the details in, or we can telnet to any of he ports found, by clicking on the "Telnet to Found Port" button. This will bring up a small box in which you can select the port to connect to and then click connect...
Something to note are the arrows on the bottom right of the config tab, when clicked, they will shrink the form to an icon in the tasktray. If the mouse pointer is held over the icon while scanning is being performed, the current scan statistics will be displayed. To restore the program, simply double click on the icon.
