Show HN: I made a Rust Terminal UI for OpenSnitch, a Linux application firewall https://ift.tt/ipjmRDr
A Rust-Powered Terminal UI for OpenSnitch: Bringing Application Firewall Control to Headless Linux Servers Application firewalls have long been an essential layer of defense for desktop operating systems, giving users visibility and control over which applications are allowed to communicate over the network. Tools like Little Snitch on macOS set a high bar for usability and transparency. On Linux, OpenSnitch fills a similar role—providing interactive, per-application network access control. In a recent Show HN post, a developer introduced a Rust-based Terminal User Interface (TUI) for OpenSnitch , designed specifically to improve usability on headless servers and terminal-only environments . The project combines practical system administration needs with a personal learning goal: mastering Rust’s async ecosystem while building something genuinely useful. What Is OpenSnitch, and Why a TUI Matters OpenSnitch is an open-source application firewall for Linux that monitors outbound network ...
