Packet capture

libpcap capture, per-interface, BPF filter, live packet count, dissected protocols.

libpcap-backed capture. Pick an interface, set a BPF filter (tcp port 443, host 10.0.5.7, etc.), hit Start.

Live view

  • Packet count
  • Bytes
  • Per-protocol dissection (Ethernet → IP → TCP/UDP → application layer)
  • One-click expand for the full dissection of a single packet

Export

Save the capture as a .pcap for Wireshark / tshark, or export the dissected JSON.
