Hi!
I have system in which arm linux is running. In system interface for wi-fi, ethernet and broadband are given.
If i configure the ip address of ethernet interface and wi-fi interface in same subnet then if i open any socket then it will try to communicate through ethernet interface, but i want to comminicate through wi-fi interface. Is there any option to specify from which interface to communicate.

Hi there

Look up the man page for setsocketopt() and the SO_BINDTODEVICE option which allows the socket to be associated with an interface name before the bind() operation.

Regards
