How am I able to log all of the data passing on a Python socket?
For audit, security and debugging purposes I've attempted creating a few wrappers around the socket object. They log all of the data passed to methods like .recv() and .sendall().
Unfortunately, there are a few main problems with that approach:
- It is not forward / backwards compatible. A new method on the socket object for sending data in any Python minor version will not be logged. I can only allow using my custom object, but that will enforce my interface, without the possibility to create
__getattr__. - In case of network disconnection in the middle of a
.sendall(), I do not know what was already sent.
Python's built-in audit does not contain anything for the actual data passed on the socket.
I wish to avoid the usage of tcpdump and stay within the confines of Python.
