I have sevarl computers, combined into network with Ethernet switch.
All are running Fedora server and have connection to Internet.

What I need is a script, which:

• Connects to all nodes from list


• Send commands (like update all or install some packages)


• Close the connection, but commands keep running on target machines

Currently, script is:

#!/bin/bash

targets_username='username'

targets_password='password'

targets_IPs=( 192.168.1.100 192.168.1.101 192.168.1.102 )



SCRIPT1='dnf update -y'

SCRIPT2='dnf update -y && poweroff'



echo "$MY_IP"

for IP in ${targets_IPs[@]}; do

        export SSHPASS=$targets_password

        script="nohup sh -c "( ( $SCRIPT1 & > /dev/null) &)""

        echo $IP

        echo $script

        sshpass -e ssh -o StrictHostKeyChecking=no -l $targets_username@$IP $script

done

The problems are:

• as soon as connection is closed, running of commands stops


• if command contains extra command like reboot or poweroff it is forwarded to main computer, from which this script started.

How to fix that?

I found posts here, here and here about possible solutions, but they didn't help.
