====== Sovol SV06+/SV07+ (mostly) ======
===== Klipper Shutdown =====
===== Linux version =====

==== Requirements ====
  * HS110 wifi power plug
  * python (should already be on your system, otherwise use ''sudo apt install python3'')
  * For simple setup using clear text passwords:
    * plink from putty-tools
    * install with ''sudo apt install putty-tools''
  * For recommended setup using ssh with a key file:
    * ssh with a private key generated by ssh-keygen and its public key pasted to the device's ''~./ssh/authorized_keys'' file
    * see ''man ssh'' and ''man ssh-keygen'' for further help
  * softScheck "tplink_smartplug.py" from https://github.com/softScheck/tplink-smartplug/tree/master

==== Setup ====

Copy the 5 files ''hs110_off'', ''hs110_on'', ''mks_poweroff '', ''shutdown_sv06'' (from below) and ''tplink_smartplug.py'' (from above link) into a single directory.

Make these files executable by using ''chmod +x *''.

Have ''putty-tools'' installed (as stated above), unless you have generated ssh keys for passwordless login.

Modify ''hs110_off'' and ''hs110_on'', so the IP-address points to your HS110 wifi power plug.

Without further modifications, these files should now work for the Sovol KlipperScreen.

For other devices, change the variables ''PRINTER'', ''USERNAME'' and ''PASSWORD'' in ''mks_poweroff'' according to your settings.

Now you should be able to shutdown and power off the device using clear text passwords by executing ''shutdown_sv06''.\\ 
To power it on, execute ''hs110_on''.

----

To use passwordless login (recommended), you need to generate a key file.\\
You can either use putty's plink or standard ssh for that, but the keys need to be generated differently.

First create the ".ssh" directory (if not already existing)
  * ''mkdir -p ~/.ssh ; chmod 700 ~/.ssh''
For plink:
  * Use ''puttygen'' to generate the key\\ Example: ''puttygen -t ed25519 -f ~/.ssh/printerkey''
  * Use ''puttygen'' again to generate and display the accompanying standard ssh **public** key\\ Example: ''puttygen ~/.ssh/printerkey -L''
  * See ''man puttgen'' for further details
For standard ssh:
  * Use ''ssh-keygen'' to generate the key\\ Example: ''ssh-keygen -t ed25519 -f ~/.ssh/printerkey''
  * Use ''cat ~/.ssh/printerkey.pub'' to display the ssh **public** key
  * See ''man ssh-keygen'' for further details.
  * Set the ''PLINKCMD'' variable in ''mks_poweroff'' to ''ssh''
Then
  * Make the keyfile unreadable to other users: ''chmod 600 ~/.ssh/printerkey''
  * Adjust the ''PLINKKEY'' variable in ''mks_poweroff'' so it points to your private key file (''~/.ssh/printerkey'' in these examples)
  * Empty the ''PASSWORD'' variable in ''mks_poweroff''
  * Log into the device using ssh and add the **public** key to ''~/.ssh/authorized_keys'':
    * ''nano ~/.ssh/authorized_keys''
    * Paste the public key line and press "CTRL+X" to quit, press "Y" to confirm once and press "ENTER" to confirm again and quit.
  * Allow user "mks" to shutdown/reboot/halt (without "sudo" asking for a password):
    * add following line to /etc/sudoers.conf (run ''sudo visudo''):\\ ''mks ALL=NOPASSWD: /sbin/halt, /sbin/reboot, /sbin/poweroff''\\ (Change "mks" to the real username, if you use a different device than Sovol's KlipperScreen.)

Now you should be able to shutdown and power off the device without clear text passwords.
