I'm looking for a lightweight packet capture solution for Windows. It needs to capture all packets on a physical network device and write them to a file (preferably
.pcap, because that's easiest for my postprocessing). I'd go with wireshark, but that maintains a graphical list and keeps a lot of the captured packets in memory, which may affect the way the system runs.
Is there something similar that will simply capture and write to a file? (All analysis can be done afterwards.)
