In order to learn sockets in Python I am trying to write a simple group chat
server and client. I need a little nudge, please. My question contains some
GUI but only as decoration. The root question is asyncore / asynchat. I
have read that twisted makes this all simple, but, I wanted to get my hands
dirty here for educational purposes.
I've managed to build a small echo server with asyncore and asynchat that can
handle any number of...

Ok.. so here is my situation.
I have an application that I would love to be able to use asynchat with for it's handle_close, found_terminator etc abstraction on.
However, I must use a separate thread for each connection as the work resulting from the communication can result in blocking for an indefinate period of time.
What I would love to do for each thread that is created, is to spin off an asynchat subclass and manually run some...

Greetings -
I've embarked on a small learning project, trying to get a better grasp of
the asyncore and asynchat modules. The project involves building a simple
instant messenger application for use on our LAN - nothing heavy duty, as
99% of my reason for doing this is just to learn.
I got my server portion working well, and I think I understand the basics.
Where I'm getting stuck is on the client side, where I'm trying to involve...

Hi there,
I am writing an application that requires a client-server interaction.
Looking up on the internet and working on it I came up with something
like this:
a class ADFSServer that takes inbound connections and dispatches them
to ADFSReceiver.
The connection is always initialized by ADFSSender.
here is the code:
import asynchat

Hello,
I'm using Python's asynchat for networking. If I invoke the send()
method of the asynchat module, only a single send operation is possible
at any given time. If I call it more than once, only the first call is
registered at the other client.
So how do I fix this? Do I have to use select etc.?
The source code is here:

Hi again,
I'm using Python's asynchat module for networking.
When calling the sendall() method of asynchat,
I sometimes get the error message "the operation
could not complete without blocking".
So how do I enable blocking with synchat, or otherwise fix this error?
Thanks for the help I've received with asynchat so far in this news group.

Hi all.
I'm (re)writing an FTP server application by using asyncore/asynchat
modules.
FTP tipically got two different channels: command and data.
I'm succesfully managing command channel through asynchat framework,
but I'm not sure about how to manage data channel without using a
thread/subprocess.
Is there an optimal to do that?
Can anyone point me in the right direction?

Hello,
I'm trying to add some better error handling to an async_chat client.
What I want is to retry or terminate gracefully if the connection to
the server doesn't succeed. Here's what I have:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
