netstat2

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.

```toml

Cargo.toml

[dependencies] netstat2 = "0.9" ```

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

Example

```rust use netstat2::{getsocketsinfo, AddressFamilyFlags, ProtocolFlags, ProtocolSocketInfo};

fn main() -> Result<(), Box> { let afflags = AddressFamilyFlags::IPV4 | AddressFamilyFlags::IPV6; let protoflags = ProtocolFlags::TCP | ProtocolFlags::UDP; let socketsinfo = getsocketsinfo(afflags, 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(())

} ```

Details

• On Windows, this library library uses GetExtendedTcpTable & GetExtendedUdpTable (iphlpapi), with an option to use the older GetTcpTable & GeUdpTable.
• On Linux and Android, it uses NETLINKINETDIAG protocol and performs pid lookup by traversing procfs.
• On macOS and iOS, it uses proc_pidfdinfo.
