I want to ssh in my server and make it shutdown and automatically boot up again at a later time.
If you shutdown the computer then how do you expect it to reboot all by itself?
Maybe you could suspend to RAM the server.
Then wake it up remotely with
Not sure if this is what you are looking for though.
I was hoping there would be a command to shut the system down and make it reboot at a later time but I guess it’s not possible.
Maybe something like
rtcwake which is included in the package: core/util-linux.
This program is used to enter a system sleep state and to automatically wake from it at a specified time.
This uses cross-platform Linux interfaces to enter a system sleep state, and leave it no later than a specified time. It uses any RTC framework driver that supports standard driver model wakeup flags.
I’m not sure because I used
wol last time years ago, but if I remember correctly, it can power on the computer (provided the hardware supports it)?
And I’ve never used
rtcwake, but that too sounds worth a try.
