Read And Write From Unix Socket Connection With Python
I'm experimenting with Unix sockets using Python. I want to create a server that creates and binds to a socket, awaits for commands and sends a response. The client would connect t
Solution 1:
SOCK_DGRAM
sockets don't listen, they just bind. Change the socket type to SOCK_STREAM
and your listen()
will work.
Check out PyMOTW Unix Domain Sockets (SOCK_STREAM
) vs. PyMOTW User Datagram Client and Server (SOCK_DGRAM
)
Solution 2:
#!/usr/bin/python
import socket
import os, os.path
import timefrom collections import deque
if os.path.exists("/tmp/socket_test.s"):
os.remove("/tmp/socket_test.s")
server = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
server.bind("/tmp/socket_test.s")
while True:
server.listen(1)
conn, addr = server.accept()
datagram = conn.recv(1024)
if datagram:
tokens = datagram.strip().split()
if tokens[0].lower() == "post":
flist.append(tokens[1])
conn.send(len(tokens) + "")
elif tokens[0].lower() == "get":
conn.send(tokens.popleft())
else:
conn.send("-1")
conn.close()
Fixed you else... and SOCK_DGRAM...
