Wireshark users can access OUI lookup information gathered during packet captures and use OUI addresses to filter traffic to and from specific addresses. Likewise, using the Wireshark OUI lookup webpage enables security professionals to access the database from a smartphone browser....
You can set the filter as: wlan.sa == xx:xx:xx... The Remote ID 802.11 frame will have a tag with type "Vendor Specific"(221) And an OUI of fa:0b:bc (Cen) The vendor specific OUI type should be 13 (0x0d) Then followed by the data. If you find a packet matching this pat...
The "slice" feature is also useful to filter on the vendor identifier part (OUI) of the MAC address, see the Ethernet page for details. Thus you may restrict the display to only packets from a specific device manufacturer. E.g. for DELL machines only: eth.addr[0:3]==00:06:5B It...

BPF 全称是 Berkeley Packet Filter(也叫 BSD Packet Filter),它是tcpdump等抓包工具的底层基础。 在BPF出现之前,虽然各家操作系统都有自己的抓包工具,但是带有各种不足。比如,有些系统把所有网络报文一股脑儿塞给用户空间程序,开销非常大;而有些系统虽然有报文过滤功能,但是工作很不稳定。

uaudp_ipv6.pcap Some traffic over ipv6. Filter on fc0c::8 and decode frame #17 (udp port 32513) as ua/udp protocol. On capture where the source and destination ports are the same, add the call server ip address in the protocol preferences to allow the correct decoding....
If the optional filter is specified, only those packets that match the filter will be used in the calculations. The table is presented with one line for each conversation and displays the number of packets/bytes in each direction as well as the total number of packets/bytes. By default, ...
