forgot root password on head- and keyboardless machine *blush*
I have a head- and keyboardless machine running debian potato that I used to log into with ssh. Now I have forgotten the password. *blush* What I want to do, is either; a) make a bootdisk with a script that automaticly starts running that disables the root password, then halts the machine. I can then log in via ssh and change/enable the password again. b) make a bootdisk that boot the machine and starts a telnet or ssh server so I can log in and mount the disk and disable the password. I think a) is preferrable to b). I can probably write the script myselfi (pointers appreciated though), but I need some info on how to assemble a bootdisk that will run this script automatically. Any input is appreciated. The machine holds no important data, so if it were not for the problem of the missing keyboard (and cdrom) I would not hesitate to reinstall it. PS: the nic in the machine requires a custum kernel, but if it is possible to boot from floppy, log in via the net via telnet or something, and do a fresh install over the network, controlled from my regular machine, then I only need to be able to make such a bootdisk. That might be simpler, as I have seen howto's on customising the kernel for the rescue disk. Regards, Stig (who is very ashamed) -- www.brautaset.org

Re: forgot root password on head- and keyboardless machine *blush*
Heh... got screwed by the AT/PS2 keyboard problem huh? Happens here at work all the time. Got a few trusty old AT-style machines and a few newer ATX cases with PS2 keyboards and mice. I'd either bite the bullet and buy a keyboard (they're not that expensive...and yours is probably looking kinda beat up now isn't it?) or I'd buy an adaptor for the AT to PS2 style. You should be able to find an adaptor at Radio Shack, Circuit City, etc. Or, raid a PC boneyard at a computer store or large business around you. They should be overflowing with junky keyboards. You probably won't care if the spacebar needs to be hit a few times, just as long as it's somewhat functional. --Rich Stig Brautaset wrote: * dman [EMAIL PROTECTED] spake thus: On Tue, Aug 21, 2001 at 06:02:07PM +0100, Stig Brautaset wrote: | I have a head- and keyboardless machine running debian potato that I | used to log into with ssh.

Regards, Stig If you have the correct cables and another computer, you could use something like Tom's Root Boot disk (www.toms.net/rb/) to start a serial console and change the password that way. You won't even need to be concerned with the NIC driver. I don't know if Tom's RBD supports serial login by default but it should be very easy to add. LNX-BBC (www.lnx-bbc.org) supports serial login but you'd need to be able to burn a CD and it might be overkill for this purpose (though it's always handy to have around). I can send you a tom's disk image with serial login support if this is an option for you. p.s. - This is just one example why it's a good idea to enable serial console support for any headless machine. :-)

What keyboard fuse? DIN isn't powered. What keyboard controller?

I'm sure it's possible to physically damage a machine if: a) you managed to short some wires together (Mac types have been warned not to plug/unplug ADB devices since circa 1984 for this reason). b) in the process of fumbling around, you managed to send a stout jolt of electrostatic discharge into the keyboard port. Physical damage should not be confused with an OS (or BIOS?) that gets confused by the sudden absense/presence of a keyboard (back to Mac, ADB addresses the devices semi-dynamically at startup IIRC, hence a potential ID conflict if you add a device later).
