什么是数据包嗅探

Packet sniffing is the practice of gathering, collecting, and logging 
some or all packets that pass through a computer network, 
regardless of how the packet is addressed. 
In this way, every packet, or a defined subset of packets, 
may be gathered for further analysis. 
You as a network administrators can use the collected data 
for a wide variety of purposes like monitoring bandwidth and traffic.
