Multi-vendor library to simplify Paramiko SSH connections to network devices.
Network automation to screen-scraping devices is primarily concerned with gathering output from show commands and with making configuration changes.
Netmiko aims to accomplish both of these operations and to do it across a very broad set of platforms. It seeks to do this while abstracting away low-level state control (i.e. eliminate low-level regex pattern matching to the extent practical).
eBPF implementation that runs on top of Windows.
eBPF is a well-known technology for providing programmability and agility, especially for extending an OS kernel, for use cases such as DoS protection and observability. This project is a work-in-progress that allows existing eBPF toolchains and APIs familiar in the Linux ecosystem to be used on top of Windows. That is, this project takes existing eBPF projects as submodules and adds the layer in between to make them run on top of Windows.
