1. 在主ya class下和main同級的層次用static 宣告函數，即可在所有主class下
使用此函數，同時，在其它程式中，只要宣告ya物件，即可用，
xx.函數來使用該方法。

Pcapdiff is a tool developed by the EFF to compare two packet captures and
identify potentially forged, dropped, or mangled packets. Two technically-
inclined friends can set up packet captures (e.g. tcpdump or Wireshark) on
their own computers and produce network traffic between their two computers
over the Internet. Later, they can run pcapdiff on the two packet capture
files to identify suspicious packets for further investigation. See
Detecting packet injection: a guide to observing packet spoofing by ISPs
and EFF's Test Your ISP Project for more background.
