I have 2 Ethernet interfaces configured in my Linux Machine.
Lets say Interface A and Interface B.

I am writing a tcp client socket program and need to send the packets on the defined interface.

For example.

./client -intf interface A/B

if it the input is interface A, then the client has to send packets only via interface A and vice versa.

Could anyone provides some hint on how to implement this?.

Thanks in advance!!!
