ICMP Ping Flood Icmp ping flood is a kind of DOS attack that can be performed on remote machines connected via a network. It involves sending a large number of ping echo requests (packets) to the target system such that it is not able to tackle so fast. So the result is that the host either gets too busy into replying these echo requests that it gets no time to serve its original purpose, or it might crash or something similar. So if a machine connected to the internet gets flooded by such a large quantity of echo packets then it wont be able to process other network activities it was intended to, and will keep very busy in replying to the echo requests. 7 thoughts on “ ICMP ping flood code using sockets in C – Linux”. Ted Mittelstaedt This code compiles out-of-box under Ubuntu 14 and runs.

But it suffers from several things; First is the call to rand. I don’t understand what the point of doing this is because you could just pad out the packet with zeros, but if you must use “random” data for padding, the rand call is extremely slow, and introduces significant delay in the code.

More importantly, when rand runs out of bits it blocks forcing the main loop to block. A better way would be to take the “fastrand” example code from here: and use that. Secondly is the call to printf – this is slow as well – it would be better to rewrite the code to print a total number of packets sent over time when the program exits – and print nothing during the flooding time. Another strange thing in there is that usleep call, it should be commented out it is not needed, not under Ubuntu 14 at least. With just these changes I’m able to do an actual flood ping that really does flood ping. Interestingly, when comparing this code out-of-box with the operating system ping program “ping -f”, the OS ping throws out more traffic than this., However, after fixing the stuff I mentioned, this program can throw out about ten times the amount of traffic that a Linux ping -f command can. Personally I suspect that the Linux ping command flooding ability is compromised because it is sending the traffic through iptables and such.
