I have written a chat server but I cannot bind my socket to an IP address:
import sys
import os
import socket
HOST = "194.118.168.131"
SOCKET_LIST = []
RECV_BUFFER = 4096
PORT = 9009
def chat_server():
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((HOST, PORT))
server_socket.listen(10)
...
I get the following error:
Traceback (most recent call last):
File "server.py", line 83, in <module>
sys.exit(chat_server())
File "server.py", line 20, in chat_server
server_socket.bind((HOST, PORT))
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 99] Cannot assign requested address
What's wrong with my code?
I didn't find an answer on:
'Connection aborted.', error(99, 'Cannot assign requested address') error in Python,
socket.error[Errno 99] Cannot assign requested address,
bind: cannot assign requested address
Cannot assign requested address - possible causes?
By checking errno.h, errno 99 is EADDRNOTAVAIL. The man page bind(2) says:
EADDRNOTAVAIL A nonexistent interface was requested or the requested address was not local.
It is often caused by a wrong IP address. You can use the command ifconfig to check whether your machine has this IP address.
