Go-ProcNet

A go module for parsing linux socket files, supporting:

• /proc/net/tcp
• /proc/net/tcp6
• /proc/net/udp
• /proc/net/udp6

Can also be used for socket files of a specific process under /proc/<PID>/net/

Based on the source code of https://github.com/cakturk/go-netstat

Installation:

$ go get github.com/otterize/go-procnet

Usage:

package main

import (
	"fmt"
	"github.com/otterize/go-procnet/procnet"
)

func main() {
	// parsing the tcp sockets from /proc/net/tcp
	socks, err := procnet.TCPSocks()
	if err != nil {
		panic(err)
	}
	for _, sock := range socks {
		fmt.Printf("local ip: %s local port: %d remote IP: %s remote port: %d state: %s",
			sock.LocalAddr.IP, sock.LocalAddr.Port, sock.RemoteAddr.IP, sock.RemoteAddr.Port, sock.State)
	}

	// for parsing the sockets from a custom path
	socks, err = procnet.SocksFromPath("/proc/1234/net/udp")
	// ...

	// for parsing the sockets from the textual content of a socket file
	socks, err = procnet.SocksFromText(` sl  local_address                         remote_address                        st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode
