    Hysteria

    Hysteria

    Hysteria is a powerful, lightning fast and censorship resistant proxy

    Hysteria is a high-performance, censorship-resistant proxy and VPN-like networking tool designed to deliver fast, reliable connectivity over unstable or lossy networks by leveraging a custom UDP/QUIC-based transport layer that can masquerade as standard HTTP/3 traffic to evade detection. It supports a wide range of use cases including SOCKS5 and HTTP proxying, TCP/UDP forwarding, Linux TProxy for network redirection, and even tunneling via TUN interfaces, making it a flexible choice for developers and network engineers needing robust remote access or traffic obfuscation. ...

    Pingtunnel is a tool that send TCP/UDP traffic over ICMP

    Pingtunnel is a Go-based tunneling tool that sends TCP and UDP traffic over ICMP. It is designed for experimental, research, and network-study scenarios where ICMP transport is being explored as an alternative path for traffic forwarding. The project uses a client and server model, with the server typically requiring a publicly reachable host. It can carry application traffic through ICMP echo-style communication, which makes it distinct from common TCP, UDP, HTTP, or DNS tunnel tools. ...
