* NpingTarget.h -- The NpingTarget class encapsulates much of the *
|
|
* information Nping has about a host. Things like next hop address or the *
|
|
* network interface that should be used to send probes to the target, are *
|
|
* stored in this class as they are determined. *

* Nmap is generally free for end users to download and use themselves, *

|
|
* *
|
|
* The Nmap license generally prohibits companies from using and *
|
|
* redistributing Nmap in commercial products, but we sell a special Nmap *
|
|
* OEM Edition with a more permissive license and special features for *
|
|
* this purpose. See https://nmap.org/oem/ *
|
|
* *
|
|
* If you have received a written Nmap license agreement or contract *

|
|
* *
|
|
* The official Nmap Windows builds include the Npcap software *
|
|
* (https://npcap.com) for packet capture and transmission. It is under *
|
|
* separate license terms which forbid redistribution without special *

|
|
* Source is provided to this software because we believe users have a *
|
|
* right to know exactly what a program is going to do before they run it. *
|
|
* This also allows you to audit the software for security holes. *
|
|
* *
|
|
* Source code also allows you to port Nmap to new platforms, fix bugs, *
|
|
* and add new features. You are highly encouraged to submit your *
|
|
* changes as a Github PR or by email to the dev@nmap.org mailing list *
|

|
|
* specify otherwise, it is understood that you are offering us very *
|
|
* broad rights to use your submissions as described in the Nmap Public *
|
|
* Source License Contributor Agreement. This is important because we *
|
|
* fund the project by selling licenses with various terms, and also *
|
|
* because the inability to relicense code has caused devastating *
|
|
* problems for other Free Software projects (such as KDE and NASM). *
