rpcsniffer 0.1.1

Capture and decode (Ethereum) JSON RPC traffic

[](https://travis-ci.org/alext234/rpc-sniffer)

# rpc-sniffer This tool captures network traffic and decode them if they contain (Ethereum) JSON RPC. This might be useful in the following scenarios:

• You want to know the exact RPC requests and responses sent to and from your Ethereum node.

• You want to debug and understand what web3 sends out.

• You want to capture the contents web3 sends out in order to use them in a different program.

# Installation

The following assumes you already have Python virtualenv activated. If not you may need to add sudo in front of the setup.py command and the pip command.

• Via the setup.py script

` git clone https://github.com/alext234/rpc-sniffer cd rpc-sniffer python setup.py install `

• Or via pip

` pip install rpcsniffer `

# Usage TODO

# Limitations

• This tool does not support encrypted SSL traffic (e.g. when you interact with an infura.io node).

• This tool does not support RPC traffic that spans multiple packets (development is in progress for this feature).
