My attempt to play with PCAPs and underlying network layers in Rust
Previously I worked with pcap parsing and pcap rewriting in python3 using scapy library. (Which is a beast in itself)
Now I am trying to build same things and gain more understanding in Rust.
pnet: I am using this library to learn the packet crafting from first principle point of viewpcap: Reading the pcap and pcapng file format file
To work with these crates, make sure you have installed libpcap on the vm. On ubuntu VM, this can be done using
sudo apt install libpcap-devFocus will be on following tasks
- Read packets from pcap/pcapng file
- Decode tcp packet out of it
- Mutate Some of field of tcp packet
- Rewrite the modified packet back to pcap
- Send this packet to some Tcp process on remote host
