So for example a tun0 network interface which is connected to a /dev/tun0 character device. IP packets arriving at tun0 to be sent can be read at user level from /dev/tun0, and packets written to /dev/tun0 are "received" by the tun0 network interface and injected into the network code. I need to do this on SunOs4.1.1 with loadable driver. It seems that Morningstar PPP uses such a tunnel device and does most of their PPP processing at user level. If anyone thinks to have answer, he'll be welcome. Answer by mail if possible. Thanks -- dorchi_c@epita.fr
