tcp-split
=========
This project is mostly used for my personal research and testing purposes.
Split TCP segments of a stream into smaller ones using Scapy and PCAP files.
Inspired and Copy&Paste from [scapy-tcp-extractor](https://github.com/deeso/scapy-tcp-extractor).
```shell
usage: TCPSplit.py [-h] [-o OUTPUT] [-s] [-l LENGTH] [-b BPF] input
positional arguments:
input PCAP input file
options:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT
PCAP output file
-s, --summary Print found TCP Streams to stdout
-l LENGTH, --length LENGTH
Split TCP payload every n bytes
-b BPF, --bpf BPF BPF filter to apply
```
You can use the `example.pcapng` which contains two TCP Streams with some ASCII content by typing:
`./TCPSplit.py -o ./splitted.pcap -l1 -s ./example.pcapng`
This will print a summary of all found TCP streams and split the TCP segments into segments of 1 byte size. The resulting `splitted.pcap` file should contain valid TCP streams.
