I would like to listen on 100 different TCP port with the same server. Here's what I'm currently doing:-

import socket
import selectdef main():server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)for i in range(1000,1100):server_socket.bind(('127.0.0.1', i))server_socket.listen(1)read_list = [server_socket]while True:readable, writable, exceptional = select.select(read_list, [], read_list)for s in readable:if s is server_socket:#print "client connected"client_socket, address = server_socket.accept()read_list.append(client_socket)else:# One of the tcp clientsdata = s.recv(1024)if not result:s.close()read_list.remove(s)#print "client disconnected"if __name__ == "__main__":main()

It returns an error saying Permission Denied. Is it because some ports(1000-1100) are reserved and are not allocated to it or because of some other reason?

I tried with (8000-8100) and it says Invalid Arguments

EDITED

import socket
import selectdef create_socket(TCP_PORT):server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)server_socket.bind(('127.0.0.1', TCP_PORT))server_socket.listen(1)return server_socketdef main():read_list = []for TCP_PORT in range(8000,8100):read_list.append(create_socket(TCP_PORT))while True:readable, writable, exceptional = select.select(read_list, [], read_list)for s in readable:if s is server_socket:#print "client connected"client_socket, address = server_socket.accept()read_list.append(client_socket)else:# One of the tcp clientsdata = s.recv(1024)if not result:s.close()read_list.remove(s)#print "client disconnected"if __name__ == "__main__":main()

There are 2 problems.

1. Ports below 1024 are reserved. (You'll need special privileges, e.g. root privileges to bind to such a port).

2. A socket can only listen at one port. So to listen to several port, you need to create one socket per port.
