Can > someone help me? Any links?... I cannot fathom why you would want to start the ppp connections from within the kernel. It does not sound like a good idea to me. In fact, as a user, I would be extremely skeptical of any driver starting ppp processes from the kernel. That said, if you're sure you want to do this, and you're positive it is the only way to solve your problem, look at call_usermodehelper(). There are restrictions on its use. Check out the source as well as Linux Device Drivers, 2nd Edition. kmod is the number-one user of call_usermodehelper(), so it would be worthwhile to read its implementation in kernel/kmod.c. (Particularly the 2.4 version _after_ the ptrace patch. :) Of course, kmod.c is evidently entirely different in the 2.5 series of kernels, which might provide a better example to learn from.
