CHScanner Description

Network scanner

The main differences between CHScanner and other similar tools are:

* CHScanner use an Operating System Mimic Tehnology;
* CHScanner has a lot more scanning methods compared with many other scanners, starting from the Layer 2 of the OSI model. It does not only scans IPv4 addresses, it also uses ARP, IGMP, IPv6 and some higher level protocols like NetBIOS, SNMP and WMI;
* It is very flexible, scanning being done based on user defined configuration files, and quite fast;
* Besides the skinnable graphical interface, CHScanner can be used from command line to automate the scans;


Operating System Mimic Tehnology short description:
Basically, this means that the packets it sends emulates the comportament of various operating systems and/or their native tools (where is the case).
Currently it emulates the following :

* Windows XP Professional SP2
* Windows 2003 Server
* Linux kernel 2.4 (Adamantix based)
* Linux kernel 2.6 (Fedora Core based)
* Solaris 8
* OpenSolaris (Nevada 35)

There is also a "random" mode where the packets have the identification data random generated.
The Solaris 8 emulation may not be continued and emulation for OpenSolaris (Nevada 35) may be added.

It is designed to run under Microsoft Windows XP and higher operating systems but, until now, I have been tested the application only in Windows XP Professional Service Pack 2 and in Windows Vista.
CHScanner needs WinPcap ("The Windows Packet Capture Library"). It has been developed and tested with WinPcap version 3.1 but, it is upgraded to work with WinPcap version 4.0.2.

More informations about the scanning types could be found in the documentation that comes with the application.
Operating System Mimic Tehnology

I will write a separate document for this...
Scanning modes

CHScanner have the following scanning modes:

* Normal mode: this is the common mode used by most of the scanners today;
* Passive mode: in this mode NO packet is sent, CHScanner only listen to the network traffic and decodes the packets received, similar to a sniffer;
* Hunt mode: introduced with version 0.9.7.2, in this mode CHScanner will scan any host that tries to communicate with the host machine. The scan is triggered by received one of the following packets destined to the local machine: ARP Request, ICMP ECHO Request, TCP SYN.
By using geolocation data provided by MaxMind you can find the country associated with a specific IPv4 Address;
* Automatic, scriptable, mode: if instructed so, by command line parameters, CHScanner will do his job based on the configuration file supplied as one of the parameters, save the result and close.

To find more information about those modes of operation read the provided documentation.

Others

* CHScanner is designed to use a minimum number of packets to do his job;
* Check for updates;
* The user can update the geolocation data;
* Skinable, why it should not be? I know that the provided skin needs a designer touch but if you do not like it just change it, it should be easy...

Quick start

* in the application's main window hit the Scan button. The Select window should appear;
* in the Select window, if you press the Examples button some example scan configurations will be created. The newly created example configuration files should be ready to run on your local network;
* in the Select window, by double-clicking a scan configuration, the scan process will start;
* after the scanning is completed, by clicking the Export XML button, the results will be saved in an XML file. The XML file will be named CHScanResult__.xml. There is a corresponding XSL file that helps you to view the exported file with a web-browser (tested with IE6, IE7 and Firefox).
