The following code behaves differently from what I would expect:
socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
System.Net.Sockets.ProtocolType.Tcp);
socket.Blocking = false;
socket.Connect(ipe);
isConnected = socket.Poll(30*1000000, SelectMode.SelectWrite);
I would have expected that once I set the socket to non-blocking, the
connect would return immediately and the poll would wait up to 30 seconds

Hello Fellow Developer,
I use the System.Net.Sockets to send/receive data (no
tcpclient/tcplistener), I made a receivethread in my wrapper, the
receivethread loops/sleeps while waiting for data and then fires a
datareceived event.
Within the waitingloop there is a timeout function, but I want the the
'last-time-socket-used' variable set when the socket is finished sending.
When I send by System.Net.Sockets.Socket.Send(buffer()) (<--this...

How can I cleanly stop a thread that is currently blocking on
Socket.Receive?
I don't want to use Thread.Abort, because I would like the thread
method to exit cleanly, and the same code must run under the Compact
Framework, which does not support Abort.
Will Socket.Close cause the Receive method to finish, or is there a
better way?

Hi,
I'm using a non-blocking connect to connect to a server.
Works fine -- the server gets and accepts the connection.
However, once the connection is established, I cannot
retrieve either the local or the remote endpoint from
the client-side socket.
The *really* strange thing is that Socket.LocalEndPoint is null.
According to the doc, that's impossible: reading the LocalEndPoint

Hi
Ii have a simple server thread in an app that listens for connections, for
some unclear reason an exception is thrown
every now and then : 'A blocking operation was interrupted by a call to
WSACancelBlockingCall '
Any suggestion why this may happen ?
The Exception is thrown by the svr.AcceptTcpClient() method
See source below.

Hi all,
under heavy load i get a SocketException when calling socket.Send method on
non blocking socket with error code 10035 WSAEWOULDBLOCK.
my question is , how do i know the number of bytes that was successfully
send (though there was an exception) so i will not have to send the whole
buffer again ?
Thanks.

Hi. I am having a problem on handling asynchronous sockets in C#. I
implemented a pair of client and server sockets. The connection is ok when
first connected. However, when I turned off the server socket, the client
is able to connect, but cannot send anything out. It seems that the
Socket.Connected is false but I received no disconnection event. Any idea
on how to solve the problem?
Thanks.

Code is at bottom. Basically, if I turn off socket blocking prior to
connecting, I get a "Socket is not connected" error when I try to send
data. However, if I do not turn off blocking, OR if I place a print
statement anywhere before the send call, it works! WTF?
I'd like to understand what's going on in the background here, if you
know don't skimp on the details.
Thanks

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,...

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...
