Keycloak Proxy

All modern Smart TVs allow you to use proxies to connect to the Internet or local network (both on Android and Tizen OS). You have to go to the device settings, open "Network" tab (can be named as "Ethernet"), and then in "Advanced settings" to activate the proxy, if necessary - specify its settings.

If you're encountering issues with parsing escaped backslashes in JSON, it's important to understand how JSON handles escape characters. In JSON, a backslash (\) is an escape character, and certain characters must be escaped to represent them in strings.

If you're working with a string that includes escaped backslashes and you want to properly parse it, make sure the JSON string itself is correctly formatted. Below is a general guide on how to handle escaped backslashes in JSON parsing:

1. Correct JSON Format:

Ensure that the JSON string is correctly formatted, and the backslashes are properly escaped. For example:

{
  "path": "C:\\Program Files\\Example"
}

In this example, the backslashes in the path are escaped with an additional backslash.

2. JSON Unmarshalling in Go:

If you're working with JSON parsing in Go (Golang), use the encoding/json package to unmarshal the JSON data into a Go struct.

Example:

package main

import (
	"encoding/json"
	"fmt"
)

type MyStruct struct {
	Path string `json:"path"`
}

func main() {
	jsonData := `{"path": "C:\\Program Files\\Example"}`

	var myStruct MyStruct
	err := json.Unmarshal([]byte(jsonData), &myStruct)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	fmt.Println("Path:", myStruct.Path)
}

In this example, the backslashes in the JSON string are properly escaped, and the json.Unmarshal function is used to parse the JSON into a Go struct.

3. Manual Handling:

If you're working with JSON data in another language or context, make sure your JSON parser correctly handles escape characters. Some JSON parsers automatically handle escape characters, while others may require manual handling.

To check if a port is available over UDP, you can try binding to the port for a short period. If the binding is successful, the port is available. If it fails, the port is already in use. Here's a simple example in Python:

import socket

def is_port_available(port, host='127.0.0.1', timeout=2):
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
        try:
            sock.bind((host, port))
            sock.settimeout(timeout)
            return True
        except OSError:
            return False
        finally:
            sock.close()

if __name__ == "__main__":
    port = 12345
    if is_port_available(port):
        print(f"Port {port} is available.")
    else:
        print(f"Port {port} is not available.")

In this example, the is_port_available function creates a UDP socket and attempts to bind to the specified port and host. If the binding is successful, the function returns True, indicating that the port is available. If the binding fails, the function returns False, indicating that the port is already in use.

Open the Chrome preferences screen, and then, expanding the advanced settings menu, click on the "Advanced" section. Open the "System" item, then on the tab that opens, click on "Open proxy settings for computer". The proxy settings interface will appear in front of you. This will be either the "System Settings" application or the "Browser Properties" application, depending on your operating system.

Shared proxies should be understood as IPs and port numbers available to everyone. That is, many users can use them simultaneously. The most unreliable and slowest option.
