Apt-Cacher NG (mbentley)
Optimize Linux package downloads with a low-overhead caching proxy. It uses native system functions for speed and includes a web frontend for statistics.
Reduce bandwidth usage and speed up software installations across your network with a specialized caching proxy for Linux distribution packages. Primarily designed for Debian and Debian-based systems, this tool efficiently caches downloaded packages so multiple machines can update without fetching the same files from the internet repeatedly. Key benefits include: Low Overhead: Operates without requiring an interpreter or massive runtime libraries. High Performance: Utilizes native system functions like mmap and sendfile instead of forking or using complex synchronization methods, ensuring minimal resource consumption. Built-in Web Frontend: Easily view detailed statistical reports and trigger administrative actions, such as importing existing package files directly into the cache. Simple Configuration: Requires only minor adjustments to client-side mirror URLs or proxy settings, with server-side setup often working perfectly out of the box.
