kping

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

Example (using af_packet recv mode)

The simplest example:

// Create a new Pingerpinger, err:=NewPinger("10.0.0.1", 100, 10, 1*time.Minute, 100*time.Millisecond)
iferr!=nil {
logger.Fatalln(err)
}
// Add IP addresses to Pingeriferr:=pinger.AddIPs([]string{"114.114.114.114", "8.8.8.8"}); err!=nil {
logger.Fatalln(err)
}
// Run !statistics, err : =pinger.Run()
iferr!=nil {
logger.Fatalln(err)
}
// Print resultforip, statistic:=rangestatistics {
fmt.Printf("%s: %v\n", ip, statistic)
}

You can customize and optimize the send & receive options based on your system:

// Create a new Pingerpinger, err:=NewPinger("10.0.0.1", 100, 10, 1*time.Minute, 100*time.Millisecond)
iferr!=nil {
logger.Fatalln(err)
}
// Set send optionsifsendOpts, err:=SendOptions(1024, 10*1024*1024, 30, 100*time.Second, 20*time.Millsecond); err!=nil{
logger.Fatalln(err)
} elseiferr:=pinger.SetOptions(sendOpts); err!=nil {
logger.Fatalln(err)
}
// Set Recv mode: afpacket | batchiferr:=pinger.SetRecvMode("afpacket"); err!=nil{
logger.Fatalln(err)
}
// Set afpacket recv mode optionsifrecvOpts, err:=AfPacketRecvOptions(2, 128, "eth1", 100*time.Millsecond); err!=nil{
logger.Fatalln(err)
} elseiferr:=pinger.SetOptions(recvOpts); err!=nil {
logger.Fatalln(err)
}
// Add IP addresses to Pingeriferr:=pinger.AddIPs([]string{"114.114.114.114", "8.8.8.8"}); err!=nil {
logger.Fatalln(err)
}
// Run !statistics, err : =pinger.Run()
iferr!=nil {
logger.Fatalln(err)
}
// Print resultforip, statistic:=rangestatistics {
fmt.Printf("%s: %v\n", ip, statistic)
}
