Quick Network Scanner Library

Rust library for scanning network hosts asynchronously.

Currently, the following scan modes are supported:

• TCP Connect;
• Ping (ICMP Echo / Echo Reply).

NOTE: in order to properly use the library you may need to increase the maximum allowed open files. E.g.:

bash ulimit -n 10000

NOTE: for the ping scan mode, you need root or other proper permissions (i.e. CAPNETRAW).

See the library on crates.io.

Usage

Dependencies (Cargo.toml):

bash [dependencies] qscan = "0.6.0" tokio = { version = "1", features = ["rt-multi-thread"] }

Alternatively, in order enable json serialization of results structures, activate serialize feature:

bash [dependencies] qscan = { version = "0.6.0" , features = ["serialize"] } tokio = { version = "1", features = ["rt-multi-thread"] }

and then (src/main.rs):

From TCP connect scan example

```rust use qscan::{QSPrintMode, QScanResult, QScanTcpConnectState, QScanType, QScanner}; use tokio::runtime::Runtime;

pub fn main() { let mut scanner = QScanner::new("8.8.8.8,127.0.0.1", "53,80,443"); scanner.setbatch(5000); scanner.settimeoutms(2000); scanner.setntries(1); scanner.setscantype(QScanType::TcpConnect); scanner.setprintmode(QSPrintMode::NonRealTime);

let res: &Vec<QScanResult> = Runtime::new().unwrap().block_on(scanner.scan_tcp_connect());

for r in res {
    if let QScanResult::TcpConnect(sa) = r {
        if sa.state == QScanTcpConnectState::Open {
            println!("{}", sa.target);
        }
    }
}

} ```
