A simple but powerful ICMP echo (ping) library for Go, inspired by

[go-fastping](https://github.com/tatsushid/go-fastping).



Here is a very simple example that sends and receives three packets:



```go

pinger, err := ping.NewPinger("www.google.com")

if err != nil {

	panic(err)

}

pinger.Count = 3

err = pinger.Run() // Blocks until finished.

if err != nil {

	panic(err)

}

stats := pinger.Statistics() // get send/receive/duplicate/rtt stats

```



Here is an example that emulates the traditional UNIX ping command:



```go

pinger, err := ping.NewPinger("www.google.com")

if err != nil {

	panic(err)

}



// Listen for Ctrl-C.

c := make(chan os.Signal, 1)

signal.Notify(c, os.Interrupt)

go func() {

	for _ = range c {

		pinger.Stop()

	}

}()



pinger.OnRecv = func(pkt *ping.Packet) {

	fmt.Printf("%d bytes from %s: icmp_seq=%d time=%v\n",

		pkt.Nbytes, pkt.IPAddr, pkt.Seq, pkt.Rtt)

}



pinger.OnDuplicateRecv = func(pkt *ping.Packet) {

	fmt.Printf("%d bytes from %s: icmp_seq=%d time=%v ttl=%v (DUP!)\n",

		pkt.Nbytes, pkt.IPAddr, pkt.Seq, pkt.Rtt, pkt.Ttl)

}



pinger.OnFinish = func(stats *ping.Statistics) {

	fmt.Printf("\n--- %s ping statistics ---\n", stats.Addr)

	fmt.Printf("%d packets transmitted, %d packets received, %v%% packet loss\n",

		stats.PacketsSent, stats.PacketsRecv, stats.PacketLoss)

	fmt.Printf("round-trip min/avg/max/stddev = %v/%v/%v/%v\n",

		stats.MinRtt, stats.AvgRtt, stats.MaxRtt, stats.StdDevRtt)

}



fmt.Printf("PING %s (%s):\n", pinger.Addr(), pinger.IPAddr())

err = pinger.Run()

if err != nil {

	panic(err)

}

```



It sends ICMP Echo Request packet(s) and waits for an Echo Reply in

response. If it receives a response, it calls the `OnRecv` callback

unless a packet with that sequence number has already been received,

in which case it calls the `OnDuplicateRecv` callback. When it's

finished, it calls the `OnFinish` callback.

[cmd/ping/ping.go](https://github.com/go-ping/ping/blob/master/cmd/ping/ping.go).



## Installation



```

go get -u github.com/go-ping/ping

```



To install the native Go ping executable:



```bash

go get -u github.com/go-ping/ping/...

$GOPATH/bin/ping

```



## Supported Operating Systems



### Linux

This library attempts to send an "unprivileged" ping via UDP. On Linux,

this must be enabled with the following sysctl command:



```

sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"

```



If you do not wish to do this, you can call `pinger.SetPrivileged(true)`

in your code and then use setcap on your binary to allow it to bind to

raw sockets (or just run it as root):



```

setcap cap_net_raw=+ep /path/to/your/compiled/binary

```



See [this blog](https://sturmflut.github.io/linux/ubuntu/2015/01/17/unprivileged-icmp-sockets-on-linux/)

and the Go [x/net/icmp](https://godoc.org/golang.org/x/net/icmp) package

for more details.



### Windows



You must use `pinger.SetPrivileged(true)`, otherwise you will receive

the following error:



```

socket: The requested protocol has not been configured into the system, or no implementation for it exists.

```



Despite the method name, this should work without the need to elevate

privileges and has been tested on Windows 10. Please note that accessing

packet TTL values is not supported due to limitations in the Go

x/net/ipv4 and x/net/ipv6 packages.



### Plan 9 from Bell Labs



There is no support for Plan 9. This is because the entire `x/net/ipv4` 

and `x/net/ipv6` packages are not implemented by the Go programming 

language.
