![]() ![]() We place people or sensors to identify the number of vehicles pass on, type (Car/bus), color and so on. ![]() ![]() Imagine you are managing a city, and you want to understand what is happening in city roads. What is packet capture and what is the benefit of doing it? ![]() In macOS and Linux this is possible with built-in NIC card with OS tools. A compatible NIC card like Airpcap is required to do this. But Wireless pcap on Windows OS, inbuilt NIC and its drivers are not possible typically. pcap on wired wont be a challenge in Windows based machines. One of the reason I chose mac is to do “wireless” packet captures. Note that the Wireshark wiki is being migrated to GitLab on August 11, 2020, so this link may become broken or possibly you'll be redirected automatically, I'm not sure.Why macOS? This is a question most of us may have. Note that not all WiFi cards support monitor mode and support may vary depending on your operating system.įor more information about WiFi capturing, I'll refer you to the Wireshark wiki page, WLAN (IEEE 802.11) capture setup. However, if you do care about management/control frames or radiotap information or capturing all traffic on a particular channel, then you will either need to set your interface card to monitor mode or use an external device capable of capturing IEEE 802.11 traffic. What you'll get instead are packets that have fake IEEE 802.3 framing instead. If you're not interested in IEEE 802.11 management/control frames or radiotap headers, and you only care about traffic to/from your capture device, then you don't need to use monitor mode. You can capture packets on a WiFi interface either in managed mode or if your hardware supports it, monitor mode too. ![]()
