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 on Windows, follow the instructions below.

Windows

• You must use a version of Rust which uses the MSVC toolchain
• You must have WinPcap or 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 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.
