Server Restart Option

Chadr619

Would like to see a 'Server Restart' option in the Cog dropdown menu just above the Logout. Also add this as a permission in the User Accounts so we can disable that option from users. This would make it easier to restart the server while using the web ui remotely.

This is already possible. See manual -> Advanced Setup. It describes how to reboot or shutdown pi. Same method can also be used to restart the server service.

Reading that document states that it would allow possible hacking and its not a secure way. I don't mind using a script as long as it can be set up to be used by approved users.

If not, then having it built into the server with user access limited to those approved would be the only other option that I can think of.

What I meant is that everyone with access to server can run it, but since it is not configurable from server it is safe. I mean it only restarts the server so it is all they can do. Also you can add a confirm dialog and set required user permission so it is as safe as it can be. Making it editable from internet would make it insecure.

Maybe I am getting a bit confused here, not explaining the request or just not understanding what you mean by using a script. So I will try to better clarify the request along with trying to clarify my understanding of the script that was mentioned.

What I am looking for is an addition to the User Profile (within Rep-Server) in the Edit Profile window to allow for selected profiles the ability to restart the daemon (service). I don't want the hardware restarted, just the daemon (service). Since I am not well versed in scripting within Ubuntu, I am making a guess that different OS versions would use different scripts to restart the Daemon service for Rep-Server. I believe this variety of script differences could be resolved by adding a Script section in Global Settings allowing an Administrator user in Rep-Server to be able to edit the script to fit the OS version they are using. Then that script would show up as an option in the Edit Profile window.

Now for my confusion on the information about a script that you recommended. I am not sure where within Rep-Server you can place a script. I read the document and I am making a guess that what is being recommended is making an OS side script outside of Rep-Server. That is not what my request involves. If I had to run the script from within the OS, then I wouldn't need a script since I could just as easily reboot the server if needed.

The whole point of the request is to have a quick and easy way to remotely restart the Rep-Server daemon while I am not near the equipment. Or in between prints, quickly restart the daemon to refresh the Rep-Server.

Hope that helps in clarifying the request... sometimes I have an idea in the mind and just can't get it across in my text.

Ok, so I understood you correctly:-)

extcommands.xml is to be placed in storage database directory, on linux /var/lib/Repetier-Server/database.
The command for restarting server is
/usr/bin/sudo service  service RepetierServer restart
Here the correct example from docs with hidden parts:

<config>
	<!--
       If you want to run external commands, enter them in this configuration with
       full path. You will see them in the main menu. Copy this file into the
       <storage>/database directory.

       Security consideration: The reason there is no online editor for this is simply
       security. The commands you enter here are executed with the privileges of the
       daemon running the server. If you would allow online configuration, a hacker could
       simply add any command he needs to hack your system.

	     Commands are normally visible in the global menu. If you want one to appear only in
	     in the printer menu, add the attribute "slugname" to command. You see the slugname
	     when you select a printer as part of the path.
    -->
	<command>
		<name>Shutdown Server</name>
		<execute>sudo /sbin/shutdown -h now</execute>
		<confirm>Really shut down the server?</confirm>
	    <!-- Define if command should show up in local printer interface, default true.-->
		<local>true</local>
	    <!-- Define if command should show up in remote printer interface, default true.-->
		<remote>true</remote>
	    <!-- Define if command should show up only for users with print permission, default true.-->
		<print-permission>true</print-permission>
	    <!-- Define if command should show up only for users with add files permission, default false.-->
		<add-permission>true</add-permission>
	    <!-- Define if command should show up only for users with del files permission, default false.-->
		<del-permission>true</del-permission>
	    <!-- Define if command should show up only for users with configuration permission, default false.-->
		<config-permission>true</config-permission>
	</command>
	<command>
		<name>Reboot Server</name>
		<execute>sudo /sbin/shutdown -r now</execute>
		<confirm>Really reboot the server?</confirm>
	</command>

	<!--
        G-code files can contain
        @execute cmd param1 param2
        commands. To prevent external users from executing unwanted or dangerous commands,
        only commands defined here are allowed to execute. More over, only the shortcuts
        defined here are to be used as cmd in @execute. Prevent parameter where ever possible.
    -->
	<execute name="play" allowParams="true">/usr/bin/afplay</execute><!-- play the sound file on moc os x -->
</config>

As you see you can exactly where and for which user permissions it should appear.
Just make sure user repetierserver can start sudo without password prompt.

Thanks! I will try this and let you know how it went. I believe I already gave repetierserver the permission to start sudo without password prompt.

Chadr619

Worked like a charm. Now only users with Configuration permissions can restart the server. Thanks!

can we have a way to restart the service in the GUI on our PC 
it does not seem to restart cleanly

how can I create a user setting that will allow "service" to be restarted
but not restart/shutdown
(but still have admin login that can )

created

 /var/lib/Repetier-Server/database/extcommands.xml

added

<command>

<name>Restart Service</name>

<execute>sudo service RepetierServer restart</execute>

<confirm>Really reboot restart service?</confirm>

</command>



these permissions seem to affect all execute commands in the config file globally, is their a way to separate them ?

<!-- Define if command should show up in local printer interface, default true.-->

<local>true</local>

    <!-- Define if command should show up in remote printer interface, default true.-->

<remote>true</remote>

    <!-- Define if command should show up only for users with print permission, default true.-->

<print-permission>true</print-permission>

    <!-- Define if command should show up only for users with add files permission, default false.-->

<add-permission>true</add-permission>

    <!-- Define if command should show up only for users with del files permission, default false.-->

<del-permission>true</del-permission>

    <!-- Define if command should show up only for users with configuration permission, default false.-->

<config-permission>true</config-permission>

On windows you have a menu entry in windows menu to start/stop the service. But see answer on other threa on why i think it is slow.

MasterCATZ

This is on Linux ,I am wanting a way to separate permissions to allow service to be restarted instead of it wanting to reboot my main pc ,, I want normal users to be able to restart service but not reboot / shutdown

sudo service RepetierServer restart

will restart the server. Try to add this in extcommands.xml just like the reboot.
