broadcast packet

[deeas]

hi everyone :
please how to change the destination address from "localhost" to the ip: "192.168.1. 1"

Static port_server As Integer = 5000
Static name_server As String = "localhost"
Static port_client As Integer = 5001

Dim sock_server As Socket = New Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp)
sock_server.EnableBroadcast = True
Dim serverEP As IPEndPoint = New IPEndPoint(Dns.GetHostEntry(name_server).AddressList(0), port_server)
Dim clientEP As IPEndPoint = New IPEndPoint(Dns.GetHostEntry(name_server).AddressList(0), port_client)
Dim enter_string As String = "hello"
Dim send_byte() As Byte
send_byte = System.Text.Encoding.ASCII.GetBytes(enter_string)
sock_server.Bind(clientEP)
sock_server.SendTo(send_byte, SocketFlags.None, serverEP)

and how to send broadcast packet.

Change:
Dim serverEP As IPEndPoint = New IPEndPoint(Dns. GetHostEntry(na me_server).Addr essList(0), port_server)
to
Dim serverEP As IPEndPoint = New IPEndPoint(Dns. GetHostEntry("1 92.168.1.1").Ad dressList(0), port_server)

However its not really a broadcast packet if you are sending it to one device. I think you need to reasearch what you reall want to do first and then decide what is right.

my question consists of tow parts , how to change the destination and how to send broadcast.

Well now my answer has two parts.
One is to change the server ip to the ip of where you want to send the message to.
The other part is to look up your questions before posting them:

good evening
please i'm trying my programs in VMware workstation, there is webserver in localhost send broadcast message and wait for responses, there is
java program running on every host , but the server couldn't receive from any one except localhost i hope you understand me and i wait your help.


Dim iep As IPEndPoint = New IPEndPoint(IPAd dress.Broadcast , 5001)
Dim Remote As EndPoint = CType(iep, EndPoint)
' sock_server.Bin d(iep)
Dim byte_recieve(25 6) As Byte
sock_server.Rec eiveFrom(byte_r ecieve, SocketFlags.Non e, Remote)

Dim server_text As String = System.Text.Enc oding.ASCII.Get String(byte_rec ieve)
TextBox2.Text = server_text

Broadcast messages aren't routed, so you all need to be on the same network for that to work
