Carrot: A Distributed Interposition Library for Networking and File Systems

Inspired by Parrot, we're building Carrot, an interposition library that captures file and networking system calls and distributes them across machines.

Set-Up

First, install necessary dependencies:

sudo apt-get update
sudo apt install g++ libprotobuf-dev libcurl4-openssl-dev libssl-dev libcrypto++-dev libresolv-dev

Then, set up the protobufs:

cd protobufs
protoc -I=. --cpp_out=./messages ./message.proto
protoc -I=. --cpp_out=./files ./file.proto

Finally, compile all of the files:

make

To Run:

File System Calls

To interpose on file system calls, look at the folder fsc. On one machine, run the receiver:

fsc/file_receiver

On another machine, run the interposition library on top of an executable doing file system calls

fsc/file_carrot fsc/file_test1

Networking System Calls

To interpose on networking system calls, look at the folder nsc. On one machine, run the receiver:

nsc/networking_receiver

On another machine, run the interposition library on top of an executable doing file system calls
