## Usage

```shell

Usage:

    NimScan  -p:- [--timeout=] [--files=] [-a]

    NimScan  -p:

    NimScan  -p:,,

    NimScan (-h | --help)

Options:

    -h, --help            Show this screen.

    -p, --ports           Ports to scan. [default: 1-65,535]

    -a, --all             Use rawsockets to find filtered/closed/open ports (Takes longer and limited to 10,000 ports).

    -t, --threads         Number of threads per scan.

    -f, --files=   File descriptors per thread limit.

    -i, --ignore          Ignore ping latency check.

    --timeout=      Timeout to add to the latency [default: 1500].

```

## Examples

Scan range between 1 to 5000 ports

```shell

NimScan 10.0.0.0/24 -p:1-5000 

```

Scan specific ports

```shell

NimScan 10.0.0.1-10.0.0.10 -p:80,443,445

```

Show closed/filtered/open using rawsockets

```shell

NimScan.exe 10.0.0.69 -a

```

## C/C++ Library 🧑🏻‍💻

### Guide

#### Exported functions

```C

scan(char * host, int * ports, int size);

scanner(char * host, int * ports, int size, char * parameters);

```

#### Options

* host        - IP/HOST to scan

* ports       - Ports to scan

* size        - Size of ports array

* parameters  - Parameters to give for the scanner as mentiond above under Usage

#### Create

```C

#include 

int main(void)

{

    NimMain(); // A MUST! 

    int ports[] = {1, 445, 8080, 3389, 135, 139};

    int size = sizeof ports / sizeof ports[0];

    

    scan(, ports, size); // Scan given ports with default configuration (timeout = 1500ms, files = 5000)

    scanner(, NULL, 0, ""); // Scanning all 65K ports with given arguments

    return 0;

}

```

#### Compile

*Make sure NimScanToC.a is in your program's folder.*

```shell

gcc .c -L. -l:NimScanToC.a -w -o NimScan.exe

```
