As I said, the lack of DNS is just the *start* of your troubles. Things just get worse once you start trying to do error handling and other similar issues. For instance, how do you intend to secure this "insert things directly into the kernel"? You *really* want to do this in userspace - if nothing else, it's a lot easier to develop and debug userspace (when a userspace program you're debugging crashes, you get a gdb prompt rather than a kernel panic), and it shouldn't be put in the kernel unless there's no reasonable way to do it in userspace. This is certainly well into the category of "If you have to ask if it's possible, you're nowhere near qualified to make it work"... --==_Exmh_1146552105_2571P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFEVv8pcC3lWbTT17ARAiGRAJ9FotAhe/ptxR7CraMk5B7sd/ZYgACfTTJA Chiec/0cl3lZciicgk59lVo= =NsaM -----END PGP SIGNATURE----- --==_Exmh_1146552105_2571P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
