Two quick questions - I have both VGA and MDA cards + monitors. In DOS I can run both, switching using the mode command. Can I do this for 388/ix? Is it possible to run shutdown from anything other than the console VT? Sometimes I would like to be able to reboot my system safely from a remote login, but can't. jon

Easy: - login from remote - make yourself root (via "su" or whatever) - cd / ; sync ; sync - /etc/init 0 That's it. Your system comes down safely. But - now user is warned. After "init 0" you have no chance to cancel. -Axel -- fischer@utower.gopas.sub.org / fischer@db0tui6.BITNET / fischer@tmpmbx.UUCP Bang-Europe : ...!{doitcr,gopnbg,tmpmbx}!utower!fischer Bang-USA : ...!uunet!unido!gopnbg!utower!fischer Too low for zero ...

Init will tell you that you must be on the console to run "init 0".

On 386/ix 2.0.x, at least, it works from any terminal. I just tried it now. You can use init 0 to shut down or init 5 or init 6 to reboot. Very handy when you're dialed in to your home machine from work or vice versa. If only they'd fix the serial drivers to work at a reasonable speed. -- John R.

In 386/ix 2.0.2, init 0, when run on a terminal other than the console, echos: Can only invoke init 0 from the console However, "init 0 < /dev/console" does have the desired effect. -- +-----------------------------------------------------------------------+ | Conor P.
