Package kping implements large scale & high performance ICMP flood ping.
It can send up to 1024 ICMP packets in one system call (sendmmsg), and provides two methods for receiving packets quickly: batch, afpacket.
See API document on godoc
Warning: WORKING IN PROGRESS
The simplest example:
// Create a new Pinger
pinger, err := NewPinger("10.0.0.1", 100, 10, 1*time.Minute, 100*time.Millisecond)
if err != nil {
logger.Fatalln(err)
}
// Add IP addresses to Pinger
if err := pinger.AddIPs([]string{"114.114.114.114", "8.8.8.8"}); err != nil {
logger.Fatalln(err)
}
// Run !
statistics, err : = pinger.Run()
if err != nil {
logger.Fatalln(err)
}
// Print result
for ip, statistic := range statistics {
fmt.Printf("%s: %v\n", ip, statistic)
}You can customize and optimize the send & receive options based on your system:
// Create a new Pinger
pinger, err := NewPinger("10.0.0.1", 100, 10, 1*time.Minute, 100*time.Millisecond)
if err != nil {
logger.Fatalln(err)
}
// Set send options
if sendOpts, err := SendOptions(1024, 10*1024*1024, 30, 100*time.Second, 20*time.Millsecond); err != nil{
logger.Fatalln(err)
} else if err := pinger.SetOptions(sendOpts); err != nil {
logger.Fatalln(err)
}
// Set Recv mode: afpacket | batch
if err := pinger.SetRecvMode("afpacket"); err != nil{
logger.Fatalln(err)
}
// Set afpacket recv mode options
if recvOpts, err := AfPacketRecvOptions(2, 128, "eth1", 100*time.Millsecond); err != nil{
logger.Fatalln(err)
} else if err := pinger.SetOptions(recvOpts); err != nil {
logger.Fatalln(err)
}
// Add IP addresses to Pinger
if err := pinger.AddIPs([]string{"114.114.114.114", "8.8.8.8"}); err != nil {
logger.Fatalln(err)
}
// Run !
statistics, err : = pinger.Run()
if err != nil {
logger.Fatalln(err)
}
// Print result
for ip, statistic := range statistics {
fmt.Printf("%s: %v\n", ip, statistic)
