Dear all, In setting of linux as a router having, let's say, 4 network interfaces, let's assume that a packet is captured at the user-level process using the libpcap library. Given this packet (destination ip address of this packet), is there any use-level system call or method for quering and knowing the outgoing interface of this packet? This is related with looking up the routing table at user-level. - Yung Yi. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
