gonc 是一个基于 Golang 的 netcat 工具，旨在更方便地建立点对点通信。
主要特点
-
🔁 自动化内网穿透：零配置，双方仅需约定一个口令，使用参数
-p2p既可自动发现彼此网络地址和穿透内网建立点对点连接，使用公共 STUN 和 MQTT 服务交换地址信息。 -
🔒 端到端双向认证的加密：支持 TCP 的 TLS 和 UDP 的 DTLS 加密传输，可基于口令双向身份认证。
-
🧩 灵活的服务配置：通过参数
-e可灵活的设置为每个连接提供服务的应用程序，例如-e /bin/sh可提供远程cmdshell，还可以使用内置的虚拟命令便捷的使用socks5服务、http文件服务和流量转发功能。
gonc is a Golang-based netcat tool designed to facilitate peer-to-peer communication.
Main Features
-
🔁 Automated NAT Traversal: Zero configuration. Both sides only need to agree on a passphrase. By using the -p2p parameter, peers can automatically discover each other’s network addresses and establish a point-to-point connection through NAT traversal, leveraging public STUN and MQTT services for address exchange.
-
🔒 End-to-End Encrypted with Mutual Authentication: Supports TLS for TCP and DTLS for UDP encrypted transmission, with passphrase-based mutual identity authentication.
-
🧩 Flexible Service Configuration: With the -e parameter, you can flexibly set the application to serve each connection. For example, -e /bin/sh can provide a remote cmd shell. You can also use built-in virtual commands for convenient SOCKS5 service, HTTP file service, and traffic forwarding.
