That's a significant difference. There was a time when excessively large packets could crash systems. That bug has long ago been fixed. The only people who have to worry about it are those who haven't updated their operating systems since 1998. The “Ping of Death” is a packet bigger than 64KB — not 64 bytes.

The meaning of pipe 2 in ping is: that the pipe is created (before) and not in use, create the file descriptors and assign to the read write vars. The meaning of pipe 3 in ping is: create a pipe and then do what pipe 2 does. In some cases( some OS ): Pipe 2 and pipe 3 are the same. Pipe 2 is a system call, and pipe 3 is one of the library function calls. In the OS where no library call is available, a system call is made. Hope this clears. Please let me know of any error. Let me look at your IFG comment. You seem to be right, I will test and comment back @Bernd: Sorry for the (very very) late reply:
