Hi,
My setup is the following: I have socket s from which I want to read
and write. So I made the following set up:
There is a thread whose only job is to read. Any data read (from recv
call) is just passed to (some) Queue. This thread is "owned" by a
second thread waiting on a Queue for write requests. The thread just
pops these from the Queue, and calls the send method from the socket.
This thread also takes care of closing the...

Thanks to everyone that responded to my previous Socket Programming question. Now I have run into some behavior that I don't quite understand.
Programming environment. VS.NET 2003, C#, Windows XP.
About the architecture:
I have a socket server dll that contains a class that handles connections for a given local ipaddress and port. This class(server) can be started or stopped by calls to the appropriate functions. The server class has...

I read a network programming book (based on framework 1.1) which indicated
that you should 'never' use the RecieveTimeout or the SendTimeout 'socket
options' on TCP sockets or you may loose data. I now see the
socket.RecieveTimeout 'property' in the visual studio 2005 help
documentation (framework 2.0) and it has example of it being used with TCP
socket. This propery is also listed as 'new in .net 2.0'.
1) is the socket.RecieveTimeout...

Hi,
I am writing an asychronous socket server to handle 20+ simulataneous
connections.
I have used the example in MSDN as a base. The code is shown at end of
question.
Each connection has a number of different types of data coming in. I have a
databuffer for each type of data coming in.

I have what I imagine is a well-known .Net networking problem, but even
though I've Googled for some time I've not yet come across a thread
where this has been fully explained...
There is a fairly common idiom (at least in the Java/UNIX/Win32 worlds)
where a socket connection is established and the program then utilises
two threads: one dedicated to reading from the socket and the other one
concurrently writing to the socket - both using...

I am trying to create a socket server which will listen for connections from
multiple clients and call subroutines in a Fortran DLL and pass the results
back to the client. The asynchronous socket client and asynchronous socket
server example code provided in the .NET framework developers guide is a
great start but I have not dealt with sockets before and I am struggling with
something.
From what I can tell the sample server code ...

Hi Everyone,
My apologies for a somewhat dump question but I am really stuck. I have
been working on this code for two days straight I am dont know what is
wrong with it. when I run the code, All I get is Input: and the program
quits. I also tried reading this online but I didn't quite get it.
What is the diff between sin_addr and sin_addr.s_addr. My understanding
is that the latter is the IP address of my machine where as the former

Hi there.
I'm setting up test suite for a project of mine.
situations, if the socket is closed on the other end or not.
I noticed that I can "detect" such state if a call to socket.read()
returns 0 but it seems a little poor to me. :-\
Is there a reliable way to test such socket 'state'?

Dear Sir/Mam,
I have written a server code using the Windows Socket API's. Wherein I have
created the socket and bound it to a particular IP address and port number.
Later I have made the socket in non-blocking mode by using the proper socket
option ( i.e. SO_RCVTIMEO). After which with the use of recv() I am trying to
get into the receive mode. Here as the receive time out is being used the
socket should come out of the block mode after...

Hello All :
A socket question from a networking newbie. I need to create
a server that:
1) receive a message from client.
2) check that message and response to it.
3) the client get the server message and send another message.
4) finally, the server receive the message and close the connection.

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,...

Dear forum friends,
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. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
