Remote reboot via SSH?

bagleyb · Nov 16, 2006, 11:52 AM

I had a video project I was working on, and was going to VNC into my Mac from work so I could render the DVD while out.

I connected to it, but then VNC crapped out. It's not responding anymore, but I can still SSH to it. Everything is saved, so I'd like to reboot it remotely.

When I SSH to it, I login as my admin (only actually) account. I execute 'shutdown -r now' but it gives me a message that I'm not a super-user. I then executed 'su' and supply my password, and it replies with su: Sorry.

Is there another way to reboot it remotely, or restart the VNC service?

interesting. is the root account enabled? if not, that would explain why su isn't working. you should try 'sudo shutdown -r now' and see if that works. however, i've had the mac os gui not be able to load afterwards after executing this command (although i could still ssh into the machine). there's an applescript that reboots the computer correctly, but it's eluding me at the moment.

I don't have access to a X machine but will "init 6" work? I don't know if that would work as I have never tried it on X but thats how I restart my fedora box from home.

Unfortunately, I'm a Mac newbie, and I'm not quite sure where either of those files are located. I'm executing them from the bash I get when I ssh in.

The init command only returns a file not found error. The sudo command gives me a message about a lecture from a Sys Admin, and then the 3 things they should have told me. It then prompts me for a password, then gives me a command not found.

It's not that big of a deal, I'll just start it tonight before I go to bed.

Yeah I guess init 6 does not work in mac OS X it was just a guess. But yeah you would type it in terminal if it did work.

sudo shutdown -r now

sounds like your account isn't an administrator account. is this your computer or a work computer?
