If you're looking for a simple and versatile WebSocket proxy, you might want to consider websockify, which is written in Python.

Websockify is a great option for those who want a straightforward solution, while wssh, a Go-based WebSocket SSH server and client, might be more suitable for developers who prefer a more specialized tool.

If you're already invested in the Node.js ecosystem, ws2ssh, a Node.js-based WebSocket SSH proxy, could be a convenient choice.

Here are some popular WebSocket proxy options:

To configure a proxy, you'll need to specify the proxy server's address and port number.

The proxy server's address is usually in the format of an IP address or a hostname, such as 192.168.1.100 or proxy.example.com.

Proxy servers often use port 8080 by default, but this can be changed depending on the specific proxy configuration.

You can specify multiple proxy servers by separating their addresses with commas, such as proxy1.example.com,proxy2.example.com.

The proxy authentication can be configured by specifying the username and password in the proxy settings.

WebSocket is a technology that establishes a persistent connection between a client and a server. This means that once the connection is established, it remains alive for as long as needed, eliminating the need to re-establish a new connection for each data request.

This continuous connection is achieved through the use of standard HTTP/HTTPS ports (80 and 443), making it easy to navigate through restrictive network environments. This is particularly beneficial in scenarios where firewalls, ISP throttling, or geographic restrictions might otherwise block SSH or VPN connections.

WebSocket's persistent connection also enables real-time communication, making it ideal for applications that require low-latency, continuous communication, such as live chat, online gaming, or interactive web applications.

WebSocket creates a persistent connection between the client and server, keeping it alive for as long as needed. This makes it ideal for applications that require low-latency, continuous communication.

The process of tunneling can be initiated using any non-websocket protocol, such as HTTP, FTP, SSH, or any other custom protocol. The data is encapsulated in the websocket frames and sent over the websocket connection.

A WebSocket connection is established between the client and server, allowing for real-time communication. This bi-directional, real-time nature makes it well-suited for applications where low latency is critical.

Here's a breakdown of how WebSocket works:

Debugging Tips can be a real challenge when working with WebSocket connections.

Enable logging on the SSH server, WebSocket proxy, and client software to gather detailed information about the connection. This will help you identify any issues that may be occurring.

Using network analysis tools, such as Wireshark, can also be incredibly helpful. These tools allow you to capture and analyze network traffic, which can be a game-changer when trying to troubleshoot problems.

Testing the connection with different clients is another great way to isolate the issue. This can help you determine if the problem lies with the client, the server, or somewhere in between.
