netstat2

Latest version Documentation License

Cross-platform library to retrieve network sockets information. Aims to be optimal by using low-level OS APIs instead of command line utilities. Provides unified interface and returns data structures which may have additional fields depending on platform.

# Cargo.toml
[dependencies]
netstat2 = "0.11"

This is a fork based on the netstat crate by ivxvm.

Example

use netstat2::{get_sockets_info, AddressFamilyFlags, ProtocolFlags, ProtocolSocketInfo};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let af_flags = AddressFamilyFlags::IPV4 | AddressFamilyFlags::IPV6;
    let proto_flags = ProtocolFlags::TCP | ProtocolFlags::UDP;
    let sockets_info = get_sockets_info(af_flags, proto_flags)?;
    
    for si in sockets_info {
        match si.protocol_socket_info {
            ProtocolSocketInfo::Tcp(tcp_si) => println!(
                "TCP {}:{} -> {}:{} {:?} - {}",
                tcp_si.local_addr,
                tcp_si.local_port,
                tcp_si.remote_addr,
                tcp_si.remote_port,
                si.associated_pids,
                tcp_si.state
            ),
            ProtocolSocketInfo::Udp(udp_si) => println!(
                "UDP {}:{} -> *:* {:?}",
                udp_si.local_addr, udp_si.local_port, si.associated_pids
            ),
        }
    }

    Ok(())
}
