On FreeBSD 6.3 how to disable the CTRL-ALT-DEL from halting/rebooting
the system?

Best regards,

There are two ways of doing this, both described in the FreeBSD FAQ here:
Hmmm, didn't know about the second one, and doesn't seem to be working
either (on both 7.0 and 6.3):

sysctl hw.syscons.kbd_reboot=0
sysctl: unknown oid 'hw.syscons.kbd_reboot'

It seems you are right. Just checked on 6.3 and 7.0 and it does not exist. It does exist in 6.2, however.


# sysctl hw.syscons.kbd_reboot=0
hw.syscons.kbd_reboot: 1 -> 0
# sysctl hw.syscons.kbd_reboot=1
hw.syscons.kbd_reboot: 0 -> 1
# uname -a

Mystery solved.
The sysctl only exists if you have not already compiled the kernel with options SC_DISABLE_REBOOT I just checked, and all the systems that do not show this were compiled with SC_DISABLE_REBOOT
I installed a clean (vmware) 7.0 and hw.syscons.kbd_reboot exists.
