SAP Netweaver and SAP HANA are technology platforms for building and integrating SAP business applications. Communication between components uses different network protocols and some services and tools make use of custom file formats as well. While some of them are standard and well-known protocols, others are proprietaries and public information is generally not available.
pysap
is an open source Python 2 library that provides modules for crafting and sending packets
using SAP's NI, Diag, Enqueue, Router, MS, SNC, IGS, RFC and HDB
protocols. In addition, support for creating and parsing different proprietary file
formats is included. The modules are built on top of Scapy and are
based on information acquired at researching the different protocols, file formats
and services.
