Go Mtr

Go implementation of mtr. mtr combines the functionality of the 'traceroute' and 'ping' programs in a single network diagnostic tool.

As mtr starts, it investigates the network connection between the host mtr runs on and a user-specified destination host. After it determines the address of each network hop between the machines, it sends a sequence of ICMP ECHO requests to each one to determine the quality of the link to each machine. As it does this, it prints running statistics about each machine.

Getting started

• command use case

cd ./cmd
go run root.go --help

• code use case

package main

import (
	"fmt"
	"github.com/wisdomatom/go-mtr"
	"time"
)

func main() {
	tracer, err := go_mtr.NewTrace(go_mtr.Config{
		ICMP:        true,
		UDP:         false,
		MaxUnReply:  8,
		NextHopWait: time.Millisecond * 200,
	})
	if err != nil {
		panic(err)
	}
	t, err := go_mtr.GetTrace(&go_mtr.Trace{
		SrcAddr: go_mtr.GetOutbondIP(),
		DstAddr: "8.8.8.8",
		SrcPort: 65533,
		DstPort: 65535,
		MaxTTL:  30,
		Retry:   2,
	})
	if err != nil {
		panic(err)
	}
	res := tracer.BatchTrace([]go_mtr.Trace{*t}, 1)
	for _, r := range res {
		fmt.Println(r.Marshal())
		fmt.Println(r.MarshalAggregate())
	}
