UDP Socket Connection

citiz3n · 05-26-2008, 02:02 AM

Hi Guys,

Can we create a UDP Socket Connection by choosing our network interface?

Here is the description:

I have both my Ethernet and Wlan active. Both obtained unique IP address which each of them are valid IP Address. Now, i would like to write a program in which i will have to create a udp socket connection.

Will be able to create the socket connection 'WITH MY CHOICE' of Network Interface?

Please Advice.

Thank you.

Sure - just use 'bind'; otherwise the routing will be left to the operating system and to a remote client they may see some packets come from one address and some from the other address (it depends on the routing rules). 'bind' is not a requirement for data sent via UDP, but it does have its uses.

Thank you for the reply. The real question here is... i have obtained ip address for both the interfaces.. (Assume that we dont know the exact IP because it is derived from dhcp).

Now.. i would like to bind the connection to ie. Wlan network interface. Without knowing the Wlan interface IP address beforehand.. how can i bind the connection? Hope you understand what I am trying to mean here.

Tq lotz.
