I check it with use std::{thread, net::TcpListener};
fn main() {
thread::spawn(|| {
let addr = "[::]:21000";
let l1 = TcpListener::bind(addr).unwrap();
println!("listen {addr}");
while let Ok(_) = l1.accept() { }
});
let addr = "0.0.0.0:21000";
let l2 = TcpListener::bind(addr).unwrap();
println!("listen {addr}");
while let Ok(_) = l2.accept() { }
