Architecture: Server is running Debian 10, all clients are running debian/raspbian. All clients have server(s)’ public key in their ssh authorized\_keys file. I’d like to be able to call a OS shell script on the gateway to reboot or shutdown the clients. Sometimes the client will not be operational (raspberry pi3) if it reboots faster than the server. I’m using `legacyLauncher.sh` and a standalone jre for these. Ideally, a tag change script on the gateway would watch for a memory tag (say, RebootGuests) and would trigger `/root/rebootGuests.sh` on the gateway. `/root/rebootGuests.sh` would contain the following: ```auto ssh user@client1 '/sbin/reboot' ssh user@client2 '/sbin/reboot' ... ``` Right now I can’t get `/root/rebootGuests.sh` to fire from the gateway. Is there a way to do this? ---

I’m not sure about your specific request, but look into Ansible. I have about 100 raspberry pis that run ignition clients. The RPis are setup to autorun the ignition client on boot up. With a single command I can reboot or shutdown all, or a subset, of the Pis. All of my Pis run on a PoE switch. If you shut the Pis down and need to turn them on, just reboot the switch. ---

Are you sure Ignition is running as root? I usually use the zip for custom installs, but I thought the regular installer set up a service user (“ignition”) by default. If so, you need that ssh identity in the ignition user’s ~/.ssh folder. ---

Currently, the script `/root/rebootGuests.sh` just does contains ```auto #!/bin/bash wall TEST MESSAGE ``` I should see this when logged in via ssh to the server. It never seems to get called from Ignition via the gateway tag change script method. I can’t run this from a client, as they are view only (no mouse / keyboard), and may not be running the software. Basically I can’t seem to find a way to run a gateway shell script from within Ignition… ---

Show your script. Consider trying to directly run `/usr/bin/wall` from the script, for starters. ---

Ok, I just changed this. Also forgot to save before testing, D’oh! It appears to be working with the `wall` command. I’ll figure out ansible or some other method to do a shell reboot on the clients. Thanks for all the help. ---

I ssh into the clients using sshpass This is a sample script of what I use to reboot a set of Pis upon a gateway start. This is useful in the instance of upgrading a gateway, as the 32 bit clients don’t gracefully recover. ```python import os import sys ipList = [ '192.168.1.100', '192.168.1.101', '192.168.1.102', '192.168.1.103', '192.168.1.104', '192.168.1.105', ] for ip in ipList: call = 'sshpass -p supersecretpassword ssh piuser@%s sudo reboot' % ip print call os.system(call) ``` ---

> [@JordanCClark](#): > > supersecretpassword Ahhhhgg! No, just no. Jordan, you _ **really** _ need to learn to use public/private keys in SSH. And in this case, use a dedicated reboot key where the RPis constrain the key to only execute the reboot.
