问题 how to use "udptunnel" so that i will be able to send and receive udp packets over tcp probably with an example 回答1: You start udptunnel on two PCs in different networks and connect them as decribed here: http://www.cs.columbia.edu/~lennox/udptunnel/ with an example: http://wiki.leipzig.freifunk.net/Udptunnel 来源： https://stackoverflow.com/questions/3566208/how-to-forward-udp-packets-over-tcp-udptunnel

问题 I'm currently working on a python project, that requires file transmission from a client to a server via the Python socket. Here is my current code, that however doesn't transmit the whole file, but there are always some bites missing, or additional bytes, according to the file sizes. _con and con are connection wrappers connections via the python socket. Client: def _sendFile(self, path): sendfile = open(path, 'rb') data = sendfile.read() self._con.sendall(data) self._con.send(bytes('FIN',

问题 I am using spring integration to create flow for request / response architecture and also receiving arbitrary data from server. Until this stage, i checked examples from spring-integration github and advices from @Gary Russell and @Artem Bilan. Here is my gateway interface @Component @MessagingGateway(defaultRequestChannel = "toTcp.input") public interface ToTCP { byte[] send(String data, @Header("host") String host, @Header("port") int port, @Header("irregularMessageChannelName") String

问题 I'm in a hurry at the moment. My Question is, is there a way to forward UDP to TCP port? I need this for hosting a game server for my friends, I want to host Counter-Strike server for example, but it uses UDP (User Datagram Protocol) for server port, but NGROK only supports TCP (Transmission Control Protocl) & HTTP (HyperText Transfer Protocol). I tried this while ago.. ngrok tcp 127.0.0.1:27015 and as usually it will start : ngrok by @inconshreveable (Ctrl+C to quit) Session Status online

问题 I'm playing with Wireshark to debug some IoT home automation projects I'm working on. I think I'd benefit from understanding more about how HTTP and TCP/IP are actually working. Most explanations I'm finding describe HTTP as "riding on top of" TCP/IP, but I'm asking more specifically about what is actually being sent. Here's an example of a client/server interaction I captured: Client: [SYN] Server: [SYN, ACK] Client: [ACK] If I understand so far, they've now successfully established a TCP

问题 This question already has answers here : Difference between TCP and UDP? (11 answers) Closed 2 years ago . What exactly is a TCP connection? I understand there isn't a physical connection from the client to server. Is this connection just the client's socket being linked with the new socket created by the server after the three-way-handshake? Thereafter once the "connection" is set up, the sockets on either ends of the connection then know where to send their packets. How does this differ

问题 Quite new to multiprocessing here. I have a code that runs two processes. One to continuously receive data blocks from the server and put it inside a queue and the other to remove the data blocks from the queue and process it. Below is my client code: import socket import turtle import multiprocessing from multiprocessing import Process, Queue from tkinter import * class GUI: def __init__(self, master): rec_data = recv_data() self.master = master master.title("Collision Detection") self.input
