Answer 1

If your referring to when you ping you send 32 bytes and you want to increase that do
ping -l size IP address ex ping -l 2048 127.0.0.1

Answer 2

Ping Packet Size

Answer 3

Your friend is blowing smoke.

You're not going to send enough ping packets from a single machine to crash another machine, especially across the internet. The average user -- hell, the average Fortune 100 company -- doesn't have enough bandwidth to launch a single ping session that could bring down a single machine.

Also, the ping app will wait a predetermined amount of time for a response before releasing another packet. Although you can control that with the -w switch, you can't get it to release a continuous unthrottled string of packets. So you can't even flood a machine significantly on a gigabit network. You'd need something that could generate raw packets for that -- and no, I'm not going to tell you how to do it or where to get it.

To bring a single host down would require a reflective DOS attack that would cause thousants of separate machines to attempt to flood the target machine with ping packets. Even then, the target would need to have a fast enough internet connection that it could pump more data into the machine than the NIC could handle. ISPs and carriers are aware of this and will usually throttle bandwidth when an abnormally large volume of ICMP connections hits a single host simultaneously from multiple machines. (FYI, before you start looking for something to try that with, keep in mind that it's quite illegal and if you don't know what you're doing the likelihood of getting caught is very high.)

The short answer is that your friend didn't use the ping command by itself to crash your computer. I won't say that he didn't crash your machine, but he didn't use ping to do it.

Using ping by itself, the very best he's likely to do is to slow your internet connection down -- and he's going to need more upstream bandwidth than you have downstream bandwidth to even do that.

Answer 4

You cannot ping large packets, but you can increase the number of packets that you send for an echo request using

Example : (ping www.yahoo.com -n 20) in case you want to send 20 packets. This number can be anything.
But if your friend claims that he crashed your computer using a ping command, it is not possible

Answer 5

Ping is how fast your internet is during online play.The lower the ping the better. And if it says T/o It means time out so its good.
