Ahh yes I understand now. That script runs on the machine thats running kstars & EKOS. For me this is the same PC thats running the INDI server.
Without ssh then I'm not sure how you could shutdown the remote server. Maybe a cron job or something to check if any indi clients connected, and if not then shutdown?

You could also use INDI Watchdog driver with custom script on the remote host.

Thank you Jasem, good idea
I will try that

On my side I could not have the watchdog driver properly protect the remote installation, but I didn't involve much effort in that yet. I'd be glad if you could share information about your own configuration.

Just curios, but why no ssh? If you have an ssh server running on the Pi, then you can specify the command to run on the command line to the ssh client. Something like this would be in your shutdown script:

ssh -l pi raspberrypi sudo shutdown -h now

Of course, there would be two prerequisites to get this to work. Configure sudo to allow shutdown to run without prompting for password, and use public/private key authentication for ssh, so ssh doesn't prompt for a password.

If you're on Windows, the Putty package has a command line client called plink that can be used in place of the ssh command above. The arguments are a little different, though.

Indeed ssh is a viable solution. Idea was that both the shutdown script on Ekos side and the Watchdog script on INDI Remote side were fit for the job.

I'd suggest against sudo though, prefer adding your ssh user to a group that is authorized to shutdown the remote computer.

Well, of course...
This question is also to take care of end user, some of them don't like our geek command line, as they say

Ah yes, agreed. But in that case, I assume the setup would be different, and include an all-in-one remote server that itself provides this capability out-of-the box, and documentation to use it.

Should we default the scheduler to use example startup and shutdown scripts, with commented out features showing how to implement things in various situations?

We have a growing community here in France, around Tinkerboard, with a lot of documentation for beginners.
There is a web server on it to set and update date & time.
@patdut added a shutdown and reboot button, wich is very convenient.
But there might be some other places to do that.

Btw : i've been playing around with watchdog drivet, i must say i don't understand the xay it should be used...

@Gilles Would you care adding links to the documentation providing information on how to shutdown or reboot the Tinkerboard, per @patdut implementation?

I've just asked him to answer

Hello all,
To answer your question @TallFurryMan I just created a little nginx server on the tinkerboard that listen on the 80 port.
I set 3 scripts in the www folder of the user, one is a js that gets the date and time from the client side to set the date and time of the remote device and capture actions like shutdown and reboot. This js file call 2 php script that belong to the www-data user who is allowed to do do date, shutdown and reboot actions in a sudoers file.
Thats all.
@Jasem, I wonder if this could be an extension to the Indi Web Manager ?
