Re: [ts-7000] Simple application example using eth1 on TS7300?

["Dustin Oprea" <>]

 

To receive on a specific interface, you need to create the socket, bind the socket, and then accept on the socket. During binding, you specify an interface by its IP address, or 0.0.0.0 to listen on all.

 

When sending, simply ensure that you have a routing entry for whatever destination IP you want to direct to a certain interface.

You don't use the socket interface to do this. The networking stack is
supposed to automatically figure out which interface to send the packet
out, based on the destination IP address you specify for the packet, and
the configuration of the interfaces and routing tables as established by
ifconfig and route.
