sockets

问题 It has been almost a month since I got this problem, and I really appreciate your help. While trying to login in my Django Web App, i encounter OSError at /accounts/login/.I am able to login in 127.0.0.1:8000/admin, but not in the /accounts/login which produces the Error Code: OSError at /accounts/login/ [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions Request Method: POST Request URL: http://127.0.0.1:8000/accounts/login/ Django Version: 1

问题 I'm still confused about knowing the status of my socket connection. This is what I'm doing. client = socket.socket(socket.AF_INET,socket.SOCK_STREAM) client.connect(("127.0.0.1",9979)) while True: msg = client.recv(4096) processNotificationMessage(msg) time.sleep(0.1) I want to connect to a server and keep receiving data forever. But how can I know if my client connection was closed due to some reason? By googling a lot all I found was that the client.recv() will return an empty string or

问题 I'm not getting how to deal with HttpWebRequest.Timeout. Before, I used to set timeouts for Socket objects where it was straight-forward: Timeout set the maximum amount of time for sending or receiving a chunk of data. However, it seems HttpWebRequest.Timeout sets the timeout for the entire HTTP request. If the request is big (for instance, I'm uploading a large file with HTTP PUT), it may take hours. This leads me to setting: ... request.Timeout = System.Threading.Timeout.Infinite; Stream

问题 I've tried to write a basic TCP hole puncher for a firewall in Python 3 using the principles outlined in this article. I'm having trouble getting anything to connect, though. Here is the code: #!/usr/bin/python3 import sys import socket import _thread as thread def client(): c = socket.socket() c.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) c.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1) c.bind((socket.gethostbyname(socket.gethostname()), int(sys.argv[3]))) while(c.connect_ex

问题 I'm stuck on a problem in a C program on Linux. I know that when a processes is forked the child process inherits some things from the parent, including open file descriptors. The problem is that I'm writing a multi-process server application with a master process that accepts new connections and puts the descriptors into shared memory. When the child process attempts to read from one of these descriptors from the shared memory, on select() i got an EBADF error! How can the child process read

问题 I'm writing a proxy using .NET and C#. I haven't done much Socket programming, and I am not sure the best way to go about it. What would be the best way to implement this? Should I use Synchronous Sockets, Asynchronous sockets? Please help! It must... Accept Connections from the client on two different ports, and be able to receive data on both ports at the same time. Connect to the server on two different ports, and be able to send data on both ports as the same time. Immediately connect to
