Why does this socket connection only allow 1 send and receive?

由 蹲街弑〆低调 提交于 2019-12-07 08:01:10
问题 Background I have a simple socket server setup that I am trying to allow simultaneous connections to and echo back the data. The client side launches several threads each making its own connection to the server. This works fine for the socket.send() call, but all subsequent calls cause either a "Connection reset by peer" or a "Broken pipe". Note that I have not found the change that toggles the reset and broken pipe. I have looked here on SO for a solution, but I'm afraid I may not know what

问题 I was trying to understand FIFOs using Python under linux and I found a strange behavior i don't understand. The following is fifoserver.py import sys import time def readline(f): s = f.readline() while s == "": time.sleep(0.0001) s = f.readline() return s while True: f = open(sys.argv[1], "r") x = float(readline(f)) g = open(sys.argv[2], "w") g.write(str(x**2) + "\n") g.close() f.close() sys.stdout.write("Processed " + repr(x) + "\n") and this is fifoclient.py import sys import time def

How to avoid a Broken Pipe error when printing a large amount of formatted data?

由 雨燕双飞 提交于 2019-12-03 13:33:38
问题 I am trying to print a list of tuples formatted in my stdout . For this, I use the str.format method. Everything works fine, but when I pipe the output to see the first lines using the head command a IOError occurs. Here is my code: # creating the data data = []$ for i in range(0, 1000): pid = 'pid%d' % i uid = 'uid%d' % i pname = 'pname%d' % i data.append( (pid, uid, pname) ) # find max leghed string for each field pids, uids, pnames = zip(*data) max_pid = len("%s" % max( pids) ) max_uid =

I'm a newbie in network programming, so please forgive me if this is a dumb question :) I created 1 client and 1 SocketServer.ThreadingMixIn server on Ubuntu 10.04.2 using Python2.7, but it seems like I can only call sock.send() once in client, then I'll get a: Traceback (most recent call last): File "testClient1.py", line 33, in <module> sock.send('c1:{0}'.format(n)) socket.error: [Errno 32] Broken pipe Here's the code I wrote: testClient1.py: #! /usr/bin/python2.7 # -*- coding: UTF-8 -*- import sys,socket,time,threading sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM) try: sock.connect(

xinetd service calls python script (doesn't execute properly)

问题 I read this: You can use xinetd to add a service starting your python script. The standard input and output will be transmitted over the network on desired port, so you do not need to modify your scripts (input/raw_input and print methods will work fine). As a result, I'm using a custom xinet service to launch script.py when a TCP connection is established to 192.168.240.37:65123. The behavior is not as desired/expected. /root/script.py #! /usr/bin/python my_name = raw_input("Enter your name:
