Alternately, if you want to turn them off permanently (such that you'd have to jump through hoops to turn them back on), you could look at blacklisting the kernel modules involved. For Bluetooth, the 'bluetooth' module will probably get the job done; at a glance, it looks as if all the other modules that might be relevant depend on that one. For Wi-Fi, the 'rfkill' module might serve as a similar central place to disable things. If not, or if you want to be more specific about it, which module you'd need to blacklist would apparently depend on what Wi-Fi hardware you have. In that case, I'd suggest looking at the output of $ /sbin/lsmod | egrep 'wl|wifi' and using that to identify the module being used to drive the hardware in question. Once you've identified the module(s) you want to prohibit, you'll need to add it to a file (or add a file for it) under /etc/modprobe.d/ ; see 'man modprobe.d', and search for the keyword 'blacklist', for syntax. If you don't want to reboot to see the effect, you'll need to also remove the in-use module, via 'modprobe -r'. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
