snoop protocol

基本解释

To further restrict things, you could port the protocol details: $ snoop host 192.168.0.2 and port 25.
要进一步限制，您可以限制协议信息的端口：$ snoop host 192.168.0.2 and port 25。
You can see in this example that snoop has decoded the contents of the DNS protocol to show the raw data returned by the lookup.
在这个示例中，您可以看到，snoop 已经对 DNS 协议的内容进行了解码，以显示查找过程所返回的原始数据。
When you examine the raw data, snoop automatically formats and parses the content of the packet for you, even down to the individual protocol level.
当您查看原始数据的时候，snoop 可以自动地为您格式化并解析数据包的内容，甚至深入到每个协议级别。
