pcap_analysis

Environment

Ubuntu22.04, g++ (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, python3.10.12-64bits

Git commit message template with .stCommitMsg

Notice

  1. big endian or little endian

  2. ip 8-bits reverse

  3. "CAIDA anonymized internet traces" no ethnet header, needed to cancel "fseek(pFile, 14, SEEK_CUR);"

  4. change IO file path

pcap_analysis.cpp:

const std::string PcapPath = "./traces/trace1.pcap";

const std::string OutputPath = "./INFO/pcap_result.txt";

const std::string OutTxtPath = "./INFO/trace.txt";

const std::string OutBPath = "./INFO/binary.dat";

const std::string LoadTestPath = "./INFO/loadTest.txt";

static.py:

filePath = './INFO/loadTest.txt'

SaveFigPath = "./INFO/same3D_scatter.png"

SaveFigPath2 = "./INFO/plot5D.png"

static_lg.py:

filePath = './INFO/loadTest.txt'

SaveFigPath = "./INFO/same3D_scatter_lg.png"

SaveFigPath2 = "./INFO/plot5D_lg.png"

  1. test.pcap: with ethernet, trace1.pcap: without ethernet

  2. pcap_analysis.cpp will extract ipV4 on .pcap file, we do not consider ipV6

  3. Create OutB file first! Otherwise, no binary file will be created

Requirement

sudo apt-get install python3-tk

pip install pandas matplotlib numpy

How to Use

  1. check IO path

  2. check library (ex: #include <arpa/inet.h>、#include <netinet/in.h> and python......)

  3. check with ethernet, or without ethernet

  4. run pcap_analysis.cpp first:

g++ "pcap_analysis.cpp" -o "pcap_analysis" && "./pcap_analysis"

  1. then run static.py and static_lg.py:

python3 static.py

python3 static_lg.py

  1. remeber we are only considering ipV4, your pcap file allows ipV6, but we won't extract it
