Cross-platform network scan tool for host and service discovery.   
Aim to be simple and fast.  

## Features
- Port Scan
- Host Scan
- Async Port Scan (Unix-Like OS only)
- Async Host Scan (Unix-Like OS only)
- Service detection (Experimental)
- OS detection (Experimental)

## Installation
### Cargo Install
```
cargo install nscan
```

## Basic Usage
```
USAGE:
    nscan [FLAGS] [OPTIONS]

FLAGS:
    -s, --service               Enable service detection
    -A, --acceptinvalidcerts    Accept invalid certs (This introduces significant vulnerabilities)
    -a, --async                 Perform asynchronous scan
    -O, --OS                    Enable OS detection
    -h, --help                  Prints help information
    -V, --version               Prints version information

OPTIONS:
    -p, --port <ip_addr:port>        Scan ports of the specified host. 
                                     Use default port list if port range omitted. 
                                     Examples 
                                     -p 192.168.1.8 -s -O 
                                     -p 192.168.1.8:1-1000 
                                     -p 192.168.1.8:22,80,8080 
                                     -p 192.168.1.8 -l custom-list.txt
    -n, --network <ip_addr>          Scan hosts in specified network 
                                     Example: -n 192.168.1.0 -O
    -H, --host <host_list>           Scan hosts in specified host-list 
                                     Examples 
                                     -H custom-list.txt -O 
                                     -H 192.168.1.10,192.168.1.20,192.168.1.30 -O
    -t, --timeout <duration>         Set timeout in ms - Ex: -t 10000
    -w, --waittime <duration>        Set waittime in ms (default:100ms) - Ex: -w 200
    -r, --rate <duration>            Set sendrate in ms - Ex: -r 1
    -P, --portscantype <scantype>    Set port scan type (default:SYN) - SYN, CONNECT
    -i, --interface <name>           Specify network interface by IP address - Ex: -i 192.168.1.4
    -l, --list <file_path>           Use list - Ex: -l custom-list.txt
    -o, --output <file_path>         Save scan result in json format - Ex: -o result.json
```

## Example
Port scan with service version and OS detection   
```
sudo nscan -p 192.168.1.8 -s -O
```

Host scan with OS detection 
```
sudo nscan -n 192.168.1.0 -O  
```

-a(--async) flag for asynchronous scan  
-o(--output) option for save json format data to file  

## Supported platforms
- Linux
- macOS (OS X)
- Windows

## Note for Windows users
To build [libpnet](https://github.com/libpnet/libpnet) on Windows, follow the instructions below.
> ### Windows
> * You must use a version of Rust which uses the MSVC toolchain
> * You must have [WinPcap]https://www.winpcap.org/ or [npcap]https://nmap.org/npcap/ installed
>   (tested with version WinPcap 4.1.3) (If using npcap, make sure to install with the "Install Npcap in WinPcap API-compatible Mode")
> * You must place `Packet.lib` from the [WinPcap Developers pack]https://www.winpcap.org/devel.htm
>   in a directory named `lib`, in the root of this repository. Alternatively, you can use any of the
>   locations listed in the `%LIB%`/`$Env:LIB` environment variables. For the 64 bit toolchain it is
>   in `WpdPack/Lib/x64/Packet.lib`, for the 32 bit toolchain, it is in `WpdPack/Lib/Packet.lib`.
