Here is a program that does some of what der Mouse's device driver does but runs as program that edits /dev/kmem to disable the device /dev/vd.
AntiHijacking tool? It disables sun4's kernel ability to modload modules on fly,
Right; this is the whole point.
thus also disables things like ppp, slip, et al.
Only if your ppp/slip requires loading a kernel module at run-time. My serial IP code doesn't depend on LKMs at all. Most that do can probably be loaded in /etc/rc.local before the door is locked.
I won't call it a solution.
Well, you're welcome to call it - or not call it - whatever you like. I don't call it a solution either, but more because the security can so easily be defeated with the help of a reboot. And of course, if your environment doesn't call for "things like ppp, slip, et al", this doesn't matter at all. Nobody _has_ to use either of these things; they're just one more option available that some may choose to avail themselves of. der Mouse mouse () collatz mcrcim mcgill edu
