Hi list, I want to set a route by netlink socket but I've no idea how to do it clearly. Here I've make up a virtual interface that is ppp0 by ioctl, we want to it could communicate with peer side. We need just a route, right? Netlink can do this. As there are many attributes , we need tell kernel what's our route. But I'm not sure what we should build as attributes that we will send to kernel. Now I get a simple talk, it contains 2 attrs follow 'rtmsg' structure. RTA_DST, 192.168.1.1 -- the peer IP RTA_SRC, 192.168.1.2 -- our local IP And it cannot work, kernel return [No such Device] error. I think there are something I lost, pls help me and point out the errors.
