Unstable websocket over Tor

Does Tor support WebSockets?

It supports many transports (stdin/out, Unix sockets, TCP sockets and WebSockets). For our purposes, we will use WebSockets over Tor, which Crossbar natively supports.

Why does my WebSocket connection keep closing?

The connection to your WebSocket app might drop after 60 seconds of inactivity for one of the following reasons: Your Internet connection has a proxy or firewall that doesn't tolerate long connections. A timeout in the ALB to the WebSocket app terminates the connection.

What are the disadvantages of WebSocket?

The biggest downside to using WebSocket is the weight of the protocol and the hardware requirements that it brings with it. WebSocket requires a TCP implementation, which may or may not be a problem, but it also requires an HTTP implementation for the initial connection setup.

Can WebSockets be hacked?

Some WebSockets security vulnerabilities arise when an attacker makes a cross-domain WebSocket connection from a web site that the attacker controls. This is known as a cross-site WebSocket hijacking attack, and it involves exploiting a cross-site request forgery (CSRF) vulnerability on a WebSocket handshake.

Can WebSocket be sniffed?

How secure are WebSockets Really? Out of the box, they are not secure at all. There are a multitude of vulnerabilities that can occur with WebSockets such as replay attacks, spoofing, buffer overflows, and sniffing.

Are WebSockets blocked by firewall?

WebSocket connections generally work even if a proxy or firewall is in place. This is because they use ports 80 and 443 which are also used by HTTP connections. In some situations WebSocket connections are blocked over port 80. In this case a secure SSL connection using WSS over port 443 should successfully connect.

What will replace WebSockets?

WebTransport is a new specification that could offer an alternative to WebSockets. For applications that need low-latency, event-driven communication between endpoints, WebSockets has been the go-to choice, but WebTransport may change that.

How do I keep my WebSocket connection alive?

In order to keep the session alive, the client could keep sending a heart-beat or a ping to the server. The retry decorator, every time there is WebSocketConnectionClosedException, reconnects to the WebSocket server in a delay of 2 seconds, keeping the session alive.

What is better than WebSockets?

Server-Sent Events is a good alternative to WebSockets for simple realtime use cases that only require one-way communication (from server to client). Examples include read-only realtime apps like stock tickers, or news updates.

How many WebSockets is too many?

Using a WebSocket library of your choice to connect to the server. After the 10th connection no more connections are accepted by the server.

How much RAM does a WebSocket use?

With websockets' defaults, on the server side, a single connections uses 70 KiB of memory.

Why WebSocket is not popular?

Websockets are largely obsolete because nowadays, if you create a HTTP/2 fetch request, any existing keepalive connection to that server is used, so the overhead that pre-HTTP/2 XHR connections needed is lost and with it the advantage of Websockets.

Is WebRTC better than WebSockets?

WebRTC is known to offer peer-to-peer (P2P) communication capabilities for mobile and browser apps using the UDP whereas WebSockets establishes a client-server connection with the aid of TCP protocol. And so, WebRTCs are known to be considerably faster than WebSockets.

Is WebSocket over https secure?

Like HTTPS, WSS (WebSockets over SSL/TLS) is encrypted, thus protecting against man-in-the-middle attacks. A variety of attacks against WebSockets become impossible if the transport is secured.

Which browser does not support WebSocket?

In desktops, WebSockets are supported by Chrome version-6, version-43, version-14. Edge-14 supports WebSockets. All the versions of firefox support WebSocket. Opera version-76 and version-7 do not support WebSocket.

Why WebSocket is not popular?

Do browsers use WebSockets?

WebSocket, as an IETF standard, and with a W3C browser API, is fully supported by all modern browsers: Chrome 16 + (incl. Chrome for Android)

Is WebSocket slower than TCP?

Thus, in most cases, it's probably not a good idea to use WebSockets instead of direct TCP since you'll get about 10 times higher message throughput with the latter (note that this is not the same as data throughput).
