Node SOCKS5 Proxy

To check the quality of a proxy server, you can use one of the proxy checkers. There are a lot of them on the Internet. For example, hidemy.name. On the page of the checker you need to specify the IP-address and port of the required proxy server.

Several virtual proxy servers can be created within one device. These are special dedicated servers that only "service" such traffic. Many devices can connect to them at the same time.

In UDP communication, there is no built-in mechanism to confirm if the client has received data from the server. UDP is a connectionless protocol, which means it does not establish a connection between the client and server, and therefore, it does not provide any reliability guarantees.

However, there are some techniques you can use to improve the reliability of UDP communication and get an indication that the client has received data:

1. Acknowledgment packets: The server can send acknowledgment packets after sending data to the client. The client can then send acknowledgment packets back to the server after receiving the data. If the server does not receive the acknowledgment packets within a specific timeout period, it can assume that the client has not received the data.

2. Timeout and retransmission: The server can implement a timeout and retransmission mechanism. If the server does not receive an acknowledgment packet within a specific timeout period, it can resend the data and continue to do so until it receives an acknowledgment or reaches a predefined limit.

3. Checksums or hashes: The server can send data along with a checksum or hash value. The client can then calculate the checksum or hash of the received data and compare it with the value sent by the server. If the values match, the client can be confident that it has received the data correctly.

It is a proxy that everyone can connect to. That is, it handles absolutely all requests without interacting with the traffic in any way, without monitoring its packets.

Open the Telegram app, and then go to "Settings. Find "Data and Drive", then tap "Proxy". Activate the "Use proxy" toggle switch, then select the desired option from the suggested list. The setting is successfully completed.
