A simple, yet fast, async port scanner library for Rust. Built on async-std
A new Scanner only takes the timeout used for each port.
To run a port scan against localhost. This will return a vector of socket addresses that are listening on tcp:
```rust use asyncstd::task; use futures::future::joinall; use portscanner::Scanner; let ps = Scanner::new(Duration::fromsecs(4));
let ftr = ps.run("127.0.0.1".tostring(), 1, 65535);
let myaddrs: Vec
```
It's easy to hit the open files limit on your system. To get around this, limit the scanner to running in batches of ports at a time:
rust
let ftr = ps.run_batched("127.0.0.1".to_string(), 1, 65535, 10000);
let my_addrs: Vec<SocketAddr> = task::block_on(async { ftr.await });
println!("{:?}", my_addrs);
You can also schedule scans against multiple hosts. This will return a vector of vectors of socket addresses.
```rust
let myftr = ps.runbatched("127.0.0.1".tostring(), 1, 65535, 3000);
let dev1ftr = ps.runbatched("192.168.1.172".tostring(), 1, 65535, 3000);
let dev2ftr = ps.runbatched("192.168.1.137".tostring(), 1, 65535, 3000);
let allftrs = vec![myftr, dev1ftr, dev2ftr];
let results: Vec
```
