Hello, I am trying to get a game server running based off of a tutorial I found. I copied all the code and have got the code to look like this
import socket # Let's import the socket module import socket # Assign a port number to a variable. Assigning values such as this makes # it much easier to change, instead of having to edit every reference of the # port in the script. Note, use a port value above 1024. Popular services, such # as ftp, http, etc. use the lower port numbers and this will help to avoid conflict. port = 2020 # Here is where we will create our socket. We assign the socket to 's' by calling # the socket module and socket() function. The socket() attributes tell the socket # to create a STREAM socket type from the INET socket family. s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Next, we bind the port to the hostname. This will tell the server that we want # to use the specified port to listen on. s.bind((socket.gethostname() , port)) # Now lets tell the server to start listening for client connections. # For testing purposes, we'll setup the server to handle 1 simultaneous # connection. You can change this later if you need. s.listen(1) # Since this script will be run outside of the game, most likely in a terminal # window, we can use print() to show that the server is running. I've included # the port value in the command to display the port number. print "Game server is running on port", port # This is our main loop to handle incoming client connections. # Connections are accepted and the message is stored into a variable. # The connection information is print() 'ed to the terminal window and the message # is then sent back to the client. Then the connection is closed. while 1: conn, addr = s.accept() data = conn.recv(1024) # display client connection info print "connected...", addr, data conn.send(data) conn.close()
The problem is, I seem to get this error.
$ python server.py Game server is running on port 2020 Traceback (most recent call last): File "server.py", line 27, in <module> conn, addr = s.accept() File "/usr/lib/python2.6/socket.py", line 195, in accept sock, addr = self._sock.accept() socket.error: [Errno 22] Invalid argument
someone had told me it was something with the socket.connect. I can’t seem to find out on google how to fix the problem. If anyone can help, I would greatly appreciate it.
