Prevent Idle Shutdown
This script uses the kodi-send tool to prevent Kodi from shutting down if there are active SSH, SAMBA, or NFS connections. The script checks every 60 seconds, and if at least one connection exists the command InhibitIdleShutdown(true) is sent to Kodi.
Create /storage/.config/prevent_idle.sh with the following content:
1
#!/bin/sh
2
​
3
IDLE_SHUTDOWN_ALLOWED_LAST_STATE=-1

    NFS_ACTIVE=`netstat -tnpa | grep 'tcp.*:111.*ESTABLISHED.*' | wc -l`

    SMB_ACTIVE=`netstat -tnpa | grep 'tcp.*:445.*ESTABLISHED.*' | wc -l`

    [ $SSH_ACTIVE -gt 0 -o $NFS_ACTIVE -gt 0 -o $SMB_ACTIVE -gt 0 ] && IDLE_SHUTDOWN_ALLOWED=1 || IDLE_SHUTDOWN_ALLOWED=0 
13
      if [ $IDLE_SHUTDOWN_ALLOWED_LAST_STATE != $IDLE_SHUTDOWN_ALLOWED ] ; then
14
        IDLE_SHUTDOWN_ALLOWED_LAST_STATE=$IDLE_SHUTDOWN_ALLOWED

        kodi-send --action="AllowIdleShutdown"
16
        if [ 0 == $IDLE_SHUTDOWN_ALLOWED ] ; then
17
          kodi-send --action="InhibitIdleShutdown(false)"

Call the script from /storage/.config/autostart.sh so it runs as a background task. It will continue to monitor the state of connections until the device is halted.

Note: If you set the refresh rate under 60 seconds the checkip.dyndns.org server will probably block your requests causing the script to fail.
