Can't reboot via ssh, but can from local terminal


I have just set up a new file server using Ubuntu AMD64 (Hoary Hedgehog). My problem is that it will not restart properly from the command line from a remote machine.

I plan to administer the server via ssh. When I start the machine up I can log in OK, and do everything as normal. however if I want to restart (shutdown -r now, OR reboot) it gives the normal warning about the system going down... but it never comes up again. Right now I do have access to the computer, but I am leaving on Tuesday and EVERYTHING will have to be done via ssh. Right now, if I hit the reboot button on the computer it will restart again normally, but something weird is happening when it do it the "proper" way via the command line in ssh.

By the way, this is (so far) pretty much a normal Ubuntu install. I haven't added or changed much (yet). The machine will run headless, however when I did have it hooked up to a monitor, I started up, logged in and I WAS able to reboot using shutdown -r now... no problems whatsoever.

Any idea what is causing a hang in this case? I have spent the last 24 hours scratching my head trying to figure this out. Any help would be greatly appreciated.

Are you issuing those commands as root? With Ubuntu this is most often done using sudo before the command

Next, have you tried issueing a simple telinit 6 on the box. This should reboot the system.

Yes, I was issuing the commands as root. (I set up a root account already.)

Actually I have found what is going wrong on my own. Turns out that it is the lack of keyboard that is causing the problems. I am running headless and when I do shutdown -r now, it freezes during the POST (I think). With a keyboard installed it will reboot no problem. I will see if I can figure out some setting in the BIOS to stop it from looking for the keyboard.
