  Introduction to the Application of eBPF in Golang

We might not know how the network interface welcomes that IP packet, nor how the filesystem handles the inodes when we save a file. This boundary is called user space, which is where we write applications, libraries, and tools. But there's another world, kernel space, where the operating system's kernel resides and is responsible for managing system resources such as memor...

  Python SSH Connection Tools

Program Design Purpose: We aim to create a simple Python SSH tool library that facilitates SSH communication, SCP file transfer, and SSH port forwarding through multiple jump hosts in an SSH tunnel chain. The library is designed to provide a simple API for establishing nested SSH tunnel connections through multiple jump hosts with customizable TCP ports. This allows users or their programs to automate SSH tasks such as: Batch processing SSH connection tasks, such as connecting to multiple ser...
