QUESTION
I have a webserver with websockets set up on an ESP8266. The application runs fine on both client and server sides, sending and receiving data. However, if the server side disconnects (power cycle or upload new code), the client (Chrome) won't reconnect to the websocket. I can reload/refresh the web page, and it claims (according to the console log) to be connecting to the websocket, but it does not. The only solution I have found that works is to close the tab, and then restart a new session.
My code is heavily based on this tutorial from Random Nerd Tutorials

QUESTION
With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.
The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.
Am I missing something that others have identified?
Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.
Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?
ReferencesThis blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!
Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is https://reload4j.qos.ch/. As of 21-Jan-2022 version 1.2.18.2 has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.
...ANSWER
Answered 2022-Jan-01 at 18:43The JNDI feature was added into Log4j 2.0-beta9.
Log4j 1.x thus does not have the vulnerable code.
QUESTION
I am creating a web-socket server in C++ with Boost library. My starting point was a Boost example from this site.
I have a question with this part of code in the on_run method:
ANSWER
Answered 2022-Jan-17 at 09:35websocket::stream_base::decorator(... calls the constructor of decorator. This constructor apparently takes a callable as parameter. The lamdba that is passed has no return. Its return type is void.
See here (link by Some programmer dudes comment): https://www.boost.org/doc/libs/1_78_0/libs/beast/doc/html/beast/ref/boost__beast__websocket__stream_base__decorator/decorator/overload2.html.
QUESTION
Context
I build a webserver using boost coroutine ts, boost asio and boost beast.
There is a coroutine for reading and one for writing.
There is a message_to_send queue where messages get pushed to send to the user.
The writing coroutine checks if there is something in the message_to_send queue and sends it.
After sending the writing coroutine suspends itself for 100 milliseconds and checks again for something to write.
Problem
The writing coroutine is polling the message queue every 100 milliseconds. I like to find a solution without polling after some timer has fired.
Posible solution
Maybe ther is a solution to co_await the change of a variable. Maybe creating a async_wait_for_callback with "async_initiate"?
Code example
You can clone the project. Or use the complete example code posted here:
ANSWER
Answered 2021-Dec-12 at 15:14The classical threading solution would be a condition variable. Of course, that's not what you want - I see you even explicitly disabled ASIO threading. Good.
One way - short of providing an Asio service to implement this behaviour - would be to use timers to emulate condition variables. You could use timer that "never" expires (deadline is at timepoint::max()) and manually reset it to timepoint::min() (canceling any async_wait) or any time in the past to signify the condition. Then you can use Timer::async_wait with use_awaitable like you already know how.
Note that you still need to "manually" signal the change. This is what you want because anything else requires kernel process tracing support/hardware debugger facilities which require massive priviliges and tend to be very slow.
You might want to know about associating the
use_awaitableas the default completion token for the executor bound to your timer. See e.g. the examples: https://www.boost.org/doc/libs/1_78_0/doc/html/boost_asio/example/cpp17/coroutines_ts/echo_server_with_default.cpp (the HTML docs do NOT link these examples)

I'm a newbie in using Boost library.
I'm currently trying to connect websocket to a webpage hosting locally but having the error.

Answered 2021-Nov-02 at 16:06The source project, rsocket-js in here, seems to have transpiration misconfigured letting the default export for the RSocketTCPClient class declaration go under a default variable.
You workaround would then either to tweak the transpiler configuration in your own project or use just the default exported object as follows:
QUESTION
My objective is to have a functional version of the latest Graphql-java mixed with jetty version 10.
I have done a lot of tests, using different methods, and now I am stuck with the difference of the WebSocket implementation (on Jetty) between the version 9.4 and 10.0.6.
To test the implementation I am working on the example from the graphQL repository sample.
My tests are on the subproject servlet-hello-world, where a simple graphQL subscription is done and working on jetty 9.4
I have updated gradle to use the latest version
...ANSWER
Answered 2021-Sep-16 at 12:40The old version of Jetty was websocket implementation neutral (core, javax.websocket, jetty native websocket, etc). That proved to be too complex when multiple implementations were being used at the same time.
The new Jetty 10+ implementation requires you to use the appropriate WebSocketServletContainerInitializer for the implementation you are using. (where is one of Javax, Jakarta, or Jetty)
Since it looks like you are using javax.websocket, here's the appropriate class to use.

QUESTION
I created WebsocketHandler as it was shown in the Webflux websocket doc.
ANSWER
Answered 2021-May-27 at 08:30After some research I found that, this can be solved with the Flux itself. It is enough that we add startWith method to the Flux. As in the definition of the startWith method.
Prepend the given values before this Flux sequence.
So we prepend our Hello message to the start of the Flux and it will be published first.
QUESTION
I am trying to create a system contains network of computers where there is a master and multiple slaves. The master device would send commands over socket and slaves would answer to the commands. I found a useful material here and it worked. I was able to send data and receive answers.
So I decided to create a class for it to have server and client objects. When I created the Server and Client objects, the client object was working fine. But the Server Object although it looks like it working but it refuses connection.
...ANSWER
Answered 2021-May-15 at 19:20So after lots of searching I found out socket.gethostname() restricts the listening.
Changing it with a black string or "127.0.0.1" solved the problem for me.

Install socket-server
You can use socket-server like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
