netstat

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.

Example

```rust extern crate netstat;

use netstat::*;

fn main() { let afflags = AddressFamilyFlags::IPV4 | AddressFamilyFlags::IPV6; let protoflags = ProtocolFlags::TCP | ProtocolFlags::UDP; let socketsinfo = getsocketsinfo(afflags, protoflags).unwrap(); for si in socketsinfo { match si.protocolsocketinfo { ProtocolSocketInfo::Tcp(tcpsi) => println!( "TCP {}:{} -> {}:{} {:?} - {}", tcpsi.localaddr, tcpsi.localport, tcpsi.remoteaddr, tcpsi.remoteport, si.associatedpids, tcpsi.state ), ProtocolSocketInfo::Udp(udpsi) => println!( "UDP {}:{} -> : {:?}", udpsi.localaddr, udpsi.localport, si.associated_pids ), } } } ```

Details

On Windows, library uses GetExtendedTcpTable & GetExtendedUdpTable (iphlpapi)
On Linux, it uses NETLINKINETDIAG protocol and performs pid lookup by traversing procfs
On OS X, it should ideally use sysctls, but currently just parses netstat output (proper impletemention is mostly done in unused modules under src/integrations/osx folder, it waits for contributors with mac to finish it)
