From a central server running HP-UX, I would like to shutdown multiple Fedora PCs using a script. This in itself is not a problem. I have an account on the machines added to the sudoers file to allow them to shut down the systems, and connect to said systems using ssh. I can get the systems to shut down remotely using the command ssh -t user@host "sudo /sbin/shutdown -h now". If I run the script on the host computer it works like I would expect.
The problem I am running into is the host computer is typically accessed through one of the Fedora PCs being used to shut it down. So when I run the script, it gets to the point where it is telling the current computer to shutdown, the script is terminated and no further systems shut down.
I have tried changing the command to the following:
ssh -t user@host "sudo /sbin/shutdown -h +1" but the script wants to wait for the shutdown command to complete, which takes a minute.
ssh -t user@host "nohup sudo /sbin/shutdown -h now&" but the command seems to never even run (there is no nohup.out file generated)
ssh -t user@host "echo 'sudo /sbin/shutdown -h now' | at now + 1 minute" but the command never seems to run
I have made another script on the target PCs that merely consists of a sleep command followed by the shutdown command and tried the above with the same result. I have also tried using screen but again it seems like it doesn't work properly.
Anyone have any ideas?
Thanks
