Hello,
I have written an app which opens a TCP connection to a server and uses a protocol to communicate with it.
Specifically, I've written a python IMD client for the molecular dynamics application 'NAMD' (do searches for IMD and NAMD if you want to learn more).
The protocol is very simple: both ends of the TCP connection can send messages to the other side at any time; when data is
available on a read socket, a full packet (with known...

Hello,
I have a problem with UDP sockets. It concerns UdpClient class as well. It
throws strange exceptions on subsequent Send calls. Exception is
SocketException with native error code 10049. I noticed that it happens when
I call Send for the second time in my program. It seemed strange, so I
compiled and run Chat sample program from MSDN. To my surprise, it worked.
But then I modified it. The only change was that I duplicated sending...

Hi,
I'm writing a client/server app.
I want to run my server on "Windows Server 2003" PC.
This PC has two network cards. 1 for Internet and other is plugged into
a switch. My plan is that I'll connect 2 or 4 PC to the switch and the
server
PC will give out DHCP IP address.

Hi,
We have a range of four products that can talk to our software (Written
in C# & managed C++) via ethernet. Using standard socket class.
This has all been working fine for a long time now, under DotNet 1.1.
We have now converted the project to DotNet 2.0
Unfortunetely, the code no longer works for one of the products. The

Hi,
I am c++ standard exceptions like out_of_range, but want it to have
some nonascii message. However what returns a char* and the class is
not templated.
Do I need to write my own exception class for this purpose?
Same problem I am facing with fstream. The open function is
non-templated and takes a char* as file name. The file is always ascii,
thus no wstream is needed, but the file-name sometime contains
non-ascii character.

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,...

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...
