.NET Framework - MultiCast

Asked By sLorent

Hello!

I'd like to send a MultiCast packet, but I don't really know how to do this
with powershell.

I tried:


$multiep = New-Item
System.Net.IPEndPoint([System.Net.IPAddress]::Parse("234.5.6.7"),58432)
$sock = New-Item
System.Net.Sockets.Socket([System.Net.Sockets.AddressFamily]'InterNetwork',
[System.Net.Sockets.SocketType]'Dgram',
[System.Net.Sockets.ProtocolType]'Udp' )
$d = New-Item
System.Net.Sockets.MulticastOption([System.Net.IPAddress]::Parse("234.5.6.7"))
$iep = New-Item System.Net.IPEndPoint(System.Net.IPAddress.Any,58432)
$sock.Bind($iep);
$sock.SetSocketOption([System.Net.Sockets.SocketOptionLevel]'IP',
[System.Net.Sockets.SocketOptionName]'AddMembership', $d)
$sock.SendTo("test",[System.Net.Sockets.SocketFlags]'None', $multiep)


IS this correct?

Still stuck/looking for a solution?

I've been playing with this a bit.  I need to confirm/figure out if a
network tracing program can see this packet or not so I know it is
actually working.

One thing: "New-Item" isn't the cmdlet you're looking for to create an
instance of a class, that would be "New-Object".
