「Wireshark 捕获过滤」(capture filter),一句话解释就是抓包过滤,需要抓取哪些特定的数据包。 作用 简单来说的原因就是性能,如果明确知道需要或不需要分析某个协议类型的流量,那么就可以使用捕获过滤器进行过滤,从而节省处理器资源。因此当网卡传输大量数据流量的时候,通过捕获过滤器进行过滤是很有用处的。
“Adapter for loopback traffic capture”是环回接口,IP 地址 127.0.0.1,用于捕获本地通信流量。 “Raw IP”表示直接捕获 IP 层流量,而不依赖具体的链路层协议。 这些接口主要用于远程捕获或特定环境下的网络数据分析: “Cisco Remote Capture”接口用于与 Cisco 设备(如路由器或交换机)建立远程连接,从设备中抓取...
设置捕捉过滤器的步骤是: - 选择 capture -> options。 - 填写"capture filter"栏或者点击"capture filter"按钮为您的过滤器起一个名字并保存,以便在今后的捕捉中继续使用这个过滤器。 - 点击开始(Start)进行捕捉。 Protocol(协议): 可能的值: ether, fddi, ip, arp, rarp, decnet, lat, sca, moprc, mo...

You can use something like the following which limits the capture to UDP, even source and destination ports, a valid RTP version, and small packets. It will capture any non-RTP traffic that happens to match the filter (such as DNS) but it will capture allRTP packets in many environments....

After downloading and installing Wireshark, you can launch it and double-click the name of a network interface under Capture to start capturing packets on that interface. For example, if you want to capture traffic on your wireless network, click your wireless interface. You can configure advance...
How to set up a Wireshark capture filter A capture filter limits what the tool captures in the first place. This is useful when you want to limit the size of the data captured to the specific traffic you are interested in. It is especially helpful for long-running captures of specific tr...
