Well, once again we're back to my original statement. If you've pulled /dev/nit out (or hell, set the proper permissions on all the /dev/nit's in the building and encased all of your network cable in solid steel or some millitary-style pressurized-glass-tube nightmare, you still should make sure that someone can't get root! This is a stupid topic. If we're being this paranoid about the cables themselves, start using Kerberos. Start Encrypting. Who gives a hoot about the kernel and /dev/nit when the person has root on your system? -john
