Capture only IP traffic - the shortest filter, but sometimes very useful to get rid of lower layer protocols like ARP and STP: ip Capture only unicast traffic - useful to get rid of noise on the network if you only want to see traffic to and from your machine, not, for example, broad...
Capture only DNS (port 53) traffic: port 53 Capture non-HTTP and non-SMTP traffic on your server (both are equivalent): host http://www.example.com and not (port 80 or port 25) host http://www.example.com and not port 80 and not port 25 Capture except all ARP and DNS traffic: ...
Wireshark's dns filter is used to display only DNS traffic, and UDP port 53 is used to capture DNS traffic. Port The default DNS port is 53, and it uses the UDP protocol. Some DNS systems use ... Get Packet Analysis with Wireshark now with the O’Reilly learning platform. O’Reilly...

(1)抓包过滤器(Capture Filter) 通过设置抓包过滤器,Wireshark 仅抓取符合条件的数据包,其他的会被直接丢弃,常用于高负载网络流量场景下减少数据存储压力和后续分析时间。 作用时间:在数据包进入捕获阶段时过滤。 性能优势:通过减少需要捕获的数据包数量,降低了存储和处理的负担。 基于BPF 语法:简单但功能有限。 BPF...
