 # packetcap
 Lightweight Packet Capture with filtering option 
 
-PacketCap allows microsecond packets in Layer 2, 3 and 4 to be dumped to terminal, operates in promiscuous mode to capture packet length up to 1600 bytes. Supports filtering option to look at specific packets. The filtering syntax is implemented using <a href="https://linux.die.net/man/7/pcap-filter"> Linux pcap-filter </a>. PacketCap is lightweight and useful when wireshark or tcpdump is not available. Implemented using <a href="https://github.com/google/gopacket"> gopacket </a> library that does the heavy lifting for BPF byte code filtering and pcap-filter string to BPF byte code.
