• We directly apply classifier from training sample-2 to sample-3: wlan_2021_03_04_04-2.4Test.pcap, 20302 packets

• Looks great!

• Requirement packages

sudo apt install libpcap-dev
sudo apt install argp
sudo apt install automake autoconf
sudo apt install autotools-dev 

• Install
  • You may not need sudo. But it doesn't work without sudo on my machine.
  • make install may not be necessary if you just want the nprint executable.

autoreconf -i
sudo ./configure
sudo make
sudo make install

Repeat the following steps to make the change work

• Add filename to Makefile.am
• autoreconf -i
• sudo ./configure
• sudo make
• sudo make install

When a pcap coming, it will be processed in the following pipeline:

• New PCAPParser(FileParser)
• set_filwriter = new FileWriter
• FileParser.set_conf
  • format_and_write_header
  • fw->write_header
  • build_bitstring_header
    • mannually set the answer: header vector
• process_file
  • pcap.pcap_loop
    • packet_handler
• [pcap_parser] packet_handler
  • [file_parser] process_packet: return sp
    • in sp: set_raw
  • pcp->write_output(sp)
    • sp->get_bitstring
      • ipv4_header.get_bitstring
