Even on switched networks, you can gain some valuable information by running the packet-scanning tool on the host you want to investigate.
即使在交换的网络中，通过对您所希望研究的主机运行数据包扫描工具，您就可以获得一些有价值的信息。
So any external network sees the NAT router's IP address and the port number assigned by the router as the source computer information on each packet.
这样任何一台处于外部网络的计算机都会在发送给它的数据包里找到NAT的IP地址和由路由器分配的端口号。
When SSL is enabled, each packet of information is encrypted, so an application that requires many transmissions back and forth between client and server requires many encryptions.
在启用SSL时，每个信息包都将被加密，这样一来，需要在客户机和服务器之间来回进行很多传输的应用程序就需要进行很多加密。
VU scripts monitor your application while you use it and track what network information is sent and received at the packet level.
VUscripts当你使用它在包的级别上跟踪什么样的网络信息被发送和接受时，检测你的应用。
Another way to process the content from tcpdump is to save the raw network packet data to a file and then process the file to find and decode the information that you want.
