I am trying to use ioctl( ), with the appropriate flag for the addition and deletion of routing entries, to modify the routing table. I have an application where a client takes its interface information and sends it to the server. The server then sends it to other clients. Clients receiving that information are to integrate that information in their routing tables. Now, the problem is that, I am getting very strange behaviour from the system, when I use the ioctl( ) function.It successfully adds the entries but the when i view them in the routing table (using route) I see a REJECT flag ( ! ) with them. Hence the receiving clients cannot use that entry to route traffic to the original client. I am not sure how the ioctl( ) function interacts with the kernel and vice versa. Can anyone help me on this. Thanks, Abid Ghufran.
