tcpdump工具是一个比较老的工具，它从网上“嗅探”网络数据包，打印到stdout或记录在一个文件中。
The tcpdump tool is an older tool that "sniffs" network packets from a network and either prints them to stdout or logs them to a file.
调试可能需要使用网络包嗅探器这样的工具来捕获网络包。
Debugging can involve the use of tools such as network packet sniffers to capture network packets.
为了确定网络带宽是否够用，您首先需要使用嗅探软件和硬件测量网络中当前的工作负载。
To determine if you have adequate network bandwidth you must first measure the existing workload on the network with sniffer software or hardware.
也有一些嗅探器会嗅探网络和嗅探器本身所在计算机之间的流量。
Other sniffers sniff traffic between a network and the machine the sniffer itself is on.
任何人都可以在您的网络或远程计算机上使用包嗅探器查看交换的信息，有时甚至可以查看密码信息。

目前，嗅探是一种简单而有用的方法，能够确保Snort已安装且能够正常工作，能够监控网络流量。
For now, though, sniffing is a simple and useful way to make sure that Snort is not only installed, but working and capable of monitoring network traffic.
在不安全的网络进行嗅探cookie。
包嗅探非常出色，但如您所见，Snort的包嗅探模式假设您一直关注着显示器，急切地查看数千行网络数据。
Packet sniffing is great, but as you've seen, Snort's packet sniffing mode assumes you're hunched over your display, eagerly watching as thousands of lines of network data flies by.
嗅探是一种常见的网络数据采集和侦听方式，恶意嗅探对网络安全具有极大的危害。
Sniffing is a common way in gathering and intercepting network data, but malicious sniffing often does great harm to network security.
这样，在必要时，您就可以很容易地运行未加密的程序，当您想要“嗅探”网络，看看到底有什么东西正在通过网络时，这一点很有用。
Thus, you can easily run your program without encryption when necessary, which can be useful when you want to "sniff" the network to see what is actually traversing the wire.
