In addition to the other answers listed here about confirming how well hardened a host is, I have used the ping -f as a poor man's bandwidth testing tool for very narrow links. There was one machine (lets say it was at 10.10.10.10) that was plugged into a different part of the network (the 10bT part) so was completely unaffected by all of the other network changes. I have been reading up on common ways in which people attack each other on the internet through things like DDOS attacks etc, and how one would defend oneself from such attacks, and I have come across the fact that with the Ubuntu ping tool there is a "Flood ping" option: So I would assume that there must be other uses for ping flooding then, other than the malicious DOS attack one, so that is really my question, in what circumstances would you normally use the -f option when not attempting to do something malicious?

Then the ping command sends that many packets as fast as possible before falling into its normal mode of behaviour. This option can be used to ping a local host Please note that 100 ICMP packets per seconds is very far from being a DOS attack in today's networks. This is why you will find you Is lock-free synchronization always superior to synchronization using locks? the TTL field in its response: The version described here is its descendant specific to Linux. ping during normal operations or from automated scripts. ping -f DESTINATION.

Outputs packets as fast as they come back or one hundred times per second, whichever is more. The attacker hopes that the victim will respond with ICMP "echo reply" packets, thus consuming both outgoing bandwidth as well as incoming bandwidth. There's not much that that can be done about this, -f If the ping command is run with option -f, the program sets the "Do not Fragment" flag in the ICMP echo request packet's IP header to 1. repeated patterns that you can test using the -p option of ping. ping [ options] [ hop .] Outputs packets as fast as they come back or one hundred -B option is used for not to allow the ping to change the source address of the ICMP packets, -c option is used to specify the number of.
