I know this is an error on the server part where the s
variable is being used when the conn
variable should be used but I've been sitting here for 2 hours and cant see the mistake. The error: [WinError 10057] A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied
My code:
import socket
from _thread import *
server = '123.456.78.9'
port = 5555
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
s.bind((server, port))
except socket.error as e:
str(e)
s.listen()
print("Waiting for connections, server has been started")
def threaded_client(conn):
reply = ""
conn.sendall(str.encode("[Server, Server]Mis:200:Connected"))
while True:
try:
data = conn.recv(2048)
reply = data.decode("utf-8")
if not data:
print("Disconnected from", addr[0])
break
print("Received: ", reply)
print("Sending: ", reply)
conn.sendall(str.encode(reply))
except:
break
print("Connection to", addr[0], "has been lost!")
conn.close()
while True:
conn, addr = s.accept()
banlist = open('bannedip.bipf')
if addr[0] in banlist.read():
conn.sendall(str.encode("[Server, Server]Err:401:Banned"))
conn.close()
print("Banned ip", addr[0], ", was disconnected as their ip (", addr[0], ") is listed in the ban file")
else:
print("Connected to:", addr[0])
start_new_thread(threaded_client, (conn,))```
I figured it out! According to other people's [WinError 10057]
problems its the server refusing to use a certain sock variable. Its been like 6 hrs and i decided to check my client code and it turns out that I first declared the client
variable to be a normal socket in the __init__
function. Then in my connect
function takes this variable and modifies it to be a connected variable (so send and recv functions work in that function). Then my send function re-reads the original socket (non-connection) and uses that to send (which fails).So i did the very complicated equivalent version (in server words) of doing conn, addr = s.accept()
then making old_s = s
then s = conn then stupidly resetting conn = old_s. That's the best I can explain it i'm sorry if you didn't understand a word of it.
