Please take a look at the simple code segment below and advise me what is
wrong.
According to the help and examples I've seen it should work unless I
misunderstand
something.
The problem is that UdpClient.Receive method always throws following
exception, even though
I verified that message was successfuly received by devices and responses
were sent back:

I'm going around in circles here and need some help.
Scenario: I am using (have used) either the UDPClient class or Sockets
class to broadcast some bytes to 255.255.255.255 (udp protocol). Upon doing
so, a device (of which I will know nothing about) will receive my broadcast
and send out a broadcast of its own. Using Ethereal (LAN packet sniffer), I
can see my broadcast, and I can see the device broadcast. I cannot however

Hi, im a beginner in C# and i just cant seem to get my udp broadcasting to
work. What happens is that it just locks down on the Receive call and never
gets any data.
I have the code for the server who answers the broadcast, so i know that it
sends a reply, but i cant figure out why my C# client cant receive it..
Any input on whats wrong with my code will be appreciated

Suppose:
There are two devices on my network that both broadcast UDP datagrams
(and they both use the same portnumber 1234).
I want to create two executables that use UdpClient internally. Each
executable should only receive the datagrams from one device. Is this
possible?
Lets say the devices are 10.0.0.1 and 10.0.0.2. I have already tried
something like this:
UdpClient udpClient = new UdpClient(1234);

Hi all,
I'm currently trying to receive replies to a UDP broadcast that I sent
and I can't get it to work. I know the datagrams are sent as I see
them with WireShark, but my C# code does not see them.
Here is how I intended things to work:
Socket socket = new Socket(AddressFamily.InterNetwork,
SocketType.Dgram, ProtocolType.Udp);

Hi all,
I'm new to developing applications using networking protocols and need to figure out how to send/receive data between a server and 8 different devices. I don't have much code as I am still in the planning stages, but I'm confused about the best way to send / receive data.
On program startup I plan on sending a broadcast ping and then listening for the 8 device's responses. What is the best way to receive the data? I've done some...

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'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...
