Proxy Selling

There is often no need to use a proxy server on PS4. However, using a proxy can achieve the following results:

opening access to inaccessible social networks and streaming sites; removal of the block on a personal IP; anonymous use of services; increasing account protection from hacking and network attacks. Without the need to use a proxy server on PS4 makes no sense.

"Work via VPN" means to connect to a site, an application or a remote server via a VPN server. That is, through an "intermediary" that not only hides the real IP address, but also additionally encrypts the traffic so that it cannot be "read".

Load testing with Selenium involves simulating a large number of concurrent users to assess how a web application performs under different levels of load. While Selenium itself is primarily designed for functional testing and browser automation, you can use additional tools and frameworks in combination with Selenium to perform load testing. Here are some approaches:

1. Using Selenium Grid with Multiple Nodes:

   • Selenium Grid allows you to distribute test execution across multiple machines, called nodes. You can set up a Selenium Grid with multiple nodes, each running different browser instances.
   • Tools like JMeter or Gatling can be used to simulate concurrent user load and distribute the load across the Selenium Grid.
   • The Selenium Grid setup allows you to scale your load tests by adding more nodes.

2. Combining Selenium with JMeter:

   • JMeter is a popular open-source load testing tool. While JMeter is not designed for browser automation, you can use it to simulate user interactions at the HTTP protocol level.
   • Record user scenarios with JMeter's HTTP(S) Test Script Recorder while performing actions in the browser. Convert recorded scenarios to JMeter test plans.
   • Run the JMeter test plans to simulate concurrent users, and monitor the performance of your web application.

3. Using Headless Browsers:

   • Headless browsers (browsers without a graphical user interface) can be used to simulate user interactions without the overhead of rendering pages.
   • Tools like Selenium with headless Chrome or headless Firefox can be used for load testing. Run multiple instances of headless browsers simultaneously to simulate concurrent users.

4. Combining Selenium with Gatling:

   • Gatling is another popular open-source load testing tool that is scriptable in Scala.
   • You can write Gatling scripts to simulate user scenarios using the Selenium DSL (Domain Specific Language) provided by Gatling.
   • Gatling can be used to generate a high load on your web application and measure performance metrics.

5. Using Cloud-Based Load Testing Services:

   • Cloud-based load testing services like BlazeMeter, Flood Element, or BrowserStack can be used for Selenium-based load testing.
   • These services provide scalable infrastructure for running Selenium tests in parallel to simulate a large number of concurrent users.

6. Custom Solutions with WebDriver:

   • You can write custom scripts using Selenium WebDriver to simulate user interactions and run them concurrently using a scripting or programming language (e.g., Python, Java, etc.).
   • Implement logic to run multiple threads or processes, each simulating a user. Be cautious about the limitations and synchronization issues that may arise in a multithreaded environment.

When performing load testing with Selenium, consider the following:

• Monitor the performance of your web application to identify bottlenecks.
• Be mindful of the limitations of the testing environment, especially when running tests on local machines.
• Ensure that your load testing approach aligns with your specific testing goals and requirements.

The maximum size of an RTP (Real-time Transport Protocol) packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information.

RTP is a transport protocol specifically designed for real-time applications like audio and video streaming. It is typically used in conjunction with UDP or TCP, as it does not provide its own transport layer.

RTP packets consist of two parts:

1. Payload: This is the actual data being transmitted, which can be audio, video, or other real-time data. The payload size is determined by the application or codec being used.

2. Header: The RTP header contains metadata required for the proper processing and synchronization of the payload. The header has a fixed size of 12 bytes. The maximum size of an RTP packet can be calculated by adding the payload size and the fixed header size:

Maximum RTP packet size = Payload size + 12 bytes (RTP header)

The payload size depends on the application or codec being used. For example, if you're using an audio codec that generates 100-byte audio frames, the maximum RTP packet size would be:

Maximum RTP packet size = 100 bytes (payload) + 12 bytes (RTP header) = 112 bytes

In the case of video codecs, the payload size can be significantly larger, depending on the video resolution, compression, and frame rate.

When RTP is used over TCP or UDP, the maximum size of the RTP packet is limited by the maximum payload size supported by the underlying transport protocol. For TCP, the maximum segment size (MSS) is determined by the MTU (Maximum Transmission Unit) of the network and the TCP header size. For UDP, the maximum packet size is limited by the MTU of the network and the UDP header size.

In summary, the maximum size of an RTP packet when transmitted over TCP/UDP protocol depends on the payload size and the addition of RTP header information, as well as the underlying transport protocol's limitations.

In Key Collector settings, the user can specify parameters of the proxy server through which the program will connect to the network. In the application window, first select "Settings", then go to the "Network" tab and check "Use proxy". Its parameters can be set either manually or through a configuration file.
