In a local network, you will need two computers to do this. One will be used as a proxy server, the other as a client. Then you need to activate the proxy on the server. And on the client PC - choose to access the Internet via a local network connection (i.e. from the server). Another option is to use a web server like Nginx.
There are three types of proxies that work using three types of protocols. The weakest one is HTTP. It is long outdated and unsuitable for visiting web resources. HTTPS works through a secure protocol and is most often used for web surfing. SOCKS5 proxies are capable of working with the largest number of programs and protocols. They are also beneficial because they keep your IP address anonymous in the request header.
You can check it with the ping command from the command line in Windows. It is enough to enter it, with a space - the data of the proxy server (including the number of the port used) and press Enter. The reply message will tell you whether or not you have received a reply from the remote server. If not, the proxy is unavailable, respectively.
To scrape Binance courses data in Python, you can use web scraping libraries such as BeautifulSoup and requests. Here's an example using BeautifulSoup to scrape Binance courses
Install required libraries:
pip install beautifulsoup4 requests
Write the scraping code:
import requests
from bs4 import BeautifulSoup
def scrape_binance_courses():
url = 'https://www.binance.com/en/academy/courses'
# Send a GET request to the URL
response = requests.get(url)
# Check if the request was successful (status code 200)
if response.status_code == 200:
soup = BeautifulSoup(response.text, 'html.parser')
# Find the container containing course information
course_container = soup.find('div', {'class': 'css-7sfsgn'})
if course_container:
# Extract course details
courses = course_container.find_all('div', {'class': 'css-1jiwjuo'})
for course in courses:
course_title = course.find('div', {'class': 'css-1mg41yd'}).text
course_description = course.find('div', {'class': 'css-1q62c8m'}).text
print(f"Title: {course_title}\nDescription: {course_description}\n")
else:
print("Course container not found.")
else:
print(f"Failed to retrieve the webpage. Status code: {response.status_code}")
# Run the scraping function
scrape_binance_courses()
This example sends a GET request to the Binance Academy courses page, parses the HTML content using BeautifulSoup, and extracts course details such as title and description.
Run the code:
python your_script_name.py
A Duplex UDP Communicator is a communication system that allows for two-way communication using User Datagram Protocol (UDP). To wait for a response from the other side, you can implement a simple client-server model. Here's a high-level overview of how to achieve this:
1. Server-side:
- Bind a UDP socket to a specific port on the server.
- Start a loop that continuously listens for incoming UDP packets.
- Receive the UDP packet and extract the data.
- Process the received data and prepare a response.
- Send the response back to the client using the client's address and port extracted from the received packet.
- Continue listening for incoming packets.
2. Client-side:
- Bind a UDP socket to a specific port on the client.
- Send a UDP packet to the server's address and port.
- Start a loop that continuously listens for incoming UDP packets.
- Receive the UDP packet and extract the data.
- Process the received data and prepare a response.
- Send the response back to the server using the server's address and port extracted from the received packet.
- Continue listening for incoming packets.
To wait for a response from the other side, you can use a simple time-based approach or a more advanced synchronization mechanism.
3. Time-based approach:
- After sending a packet, wait for a specific amount of time before expecting a response.
- If a response is received within the waiting time, process the response and proceed.
- If the waiting time elapses without receiving a response, handle the timeout and take appropriate action (e.g., retry, abort, or notify the user).
4. Synchronization mechanism:
- Include a unique identifier in each packet sent.
- When the server receives a packet, it sends back a response with the same identifier.
- The client waits for a response with the same identifier before proceeding.
- If a response with the same identifier is received, process the response and proceed.
- If a response with a different identifier is received, discard it and continue waiting for the expected response.
- If no response is received within a specific time, handle the timeout and take appropriate action.
Using a synchronization mechanism is more reliable than a time-based approach, as it ensures that the client only processes responses from the expected server. However, both methods can be effective depending on the specific use case and network conditions.
