How to test whether a STUN/TURN server is working properly
A few days ago, I created a simple service for my WebRTC Project: https://github.com/miroslavpejic85/mirotalk to test if the STUN/TURN servers are working properly. After installing and configuring a STUN/TURN server, most of the developers that are new to this stuff will ask themselves, how do I know if it's working properly? So I made a snippet :) ``` Test Stun/Turn Servers Test Ice Servers The STUN server is NOT reachable! The TURN server is NOT reachable! const Ice = document.getElementById('ice'); const IP = document.getElementById('ip'); const Stun =…
In plain words
This tool tests whether STUN and TURN servers are functioning correctly for WebRTC applications. It is designed for developers who have installed and configured these servers and need to verify they are working properly. The tool provides a simple web-based interface that checks server reachability and displays diagnostic information, helping users troubleshoot connectivity issues without requiring technical expertise in WebRTC infrastructure.

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
