SA-MP Socket Plugin — SSL-Free

Overview

SA-MP Socket Plugin (SSL-Free) is a lightweight socket plugin for San Andreas Multiplayer (SA-MP) servers that provides simple TCP/UDP communication capabilities without relying on OpenSSL.

The project was created as an SSL-free rebuild of the original BlueG Socket plugin, removing external OpenSSL dependencies such as libcrypto, libeay32.dll, and ssleay32.dll. This makes deployment simpler and helps avoid common runtime dependency issues on both Windows and Linux.

Features

• Supports TCP and UDP socket communication.
• Built without OpenSSL or related external SSL libraries.
• Eliminates libcrypto dependency issues on Linux.
• Eliminates libeay32.dll and ssleay32.dll dependency issues on Windows.
• Lightweight and minimal.
• Supports both Windows and Linux server environments.
• Easy to compile from source.
• Compatible with most modern AMX-based SA-MP scripts.
• Useful for communicating with external backends such as Node.js and Python applications.
• Prebuilt binaries are available through GitHub Releases.
• Published as an Open.MP package through PawnDEX.

Installation

Windows

1. Download the latest socket.dll from the GitHub Releases page.
2. Copy socket.dll into your SA-MP server's plugins folder.
3. Copy socket.inc into pawno/include/.
4. Add the plugin to your server.cfg:

plugins socket

Linux

1. Download socket.so from the GitHub Releases page.
2. Copy socket.so into your plugins folder.
3. Copy socket.inc into pawno/include/.
4. Add the plugin to your server.cfg:

plugins socket.so

Make sure the plugin has execute permissions:

chmod +x plugins/socket.so

Usage

The plugin can be used directly from Pawn scripts to create and connect sockets:

#include <socket>

new Socket:g_socket;

public OnGameModeInit()
{
    g_socket = socket_create(TCP);
    socket_connect(g_socket, "127.0.0.1", 7000);
}

public onSocketAnswer(Socket:id, data[], data_len)
{
    printf("[TCP Server] %s", data);
}
