ExecOnMcode

[Falcounet]

Hello !

I'm pleased to announce the release of my first plugin for DSF.
ExecOnMcode is a SBC plugin for DuetSoftwareFramework and based on dsf-python to run commands on user-defined M-Codes.

This plugin is based on the original idea from wilriker's execonmcode.

Feel free to give some feedback, post the issues you may face and ask for improvements to this thread.

@falcounet thanks for this! Also thanks for submitting it to the plugin repository!

I think we should have a health warning around this advice in the documentation:

If for some reason you want to go beyond that limitation, create a 010_dsf-nopasswd file into /etc/sudoers.d/ with the following content : dsf ALL=(ALL) NOPASSWD: ALL
Then use sudo with the command you wish to run using ExecOnMcode.

outline the risks of allowing the dsf user to run su commands.

@Falcounet Like the example you have for running a python scrip and getting information baout the state of the SBC back:

Hi, I've just been looking at this as I'd like to shutdown my SBC. How do you actually go about doing it? Thanks in advance.

[Falcounet]

@r4ffers shutdown requires root privileges and thus isn't possible to use that plugin without hacks as the plugin runs as dsf user.
It is recommended to use the DuetPiManagementPlugin for shutdown.

@falcounet thankyou

Hello @Falcounet

I've tried giving this a run and during install we're coming up with the error:

Any suggestions how to resolve this? We tried installing dsf-python directly via pip install, but it did not seem to resolve it.

[Falcounet]

@e3d-tcw You need to use pip3 as it is a Python3 module. Install python3-pip package if pip3 isn't available on your system.
What DSF version do you use ? This was normally fixed in 3.4

I like this plugin. But version 0.1 is not that advanced yet. Are you ( @Falcounet ) still developing it?

[Falcounet]

@CrazyCreator No real plan so far. Can you be more explicit about what you find it "not that advanced yet" ?

[CrazyCreator]

@Falcounet said in ExecOnMcode v0.1:

@CrazyCreator No real plan so far. Can you be more explicit about what you find it "not that advanced yet" ?

sorry ... that was the bad google translator. The question was, are you still programming or is it finished?

[Falcounet]

@CrazyCreator I'm not still programming it for now but if you have improvement or feature requests, I can consider them.

[CrazyCreator]

That sounds good... will try it out in the next few days.

Raspi 4 with bullseye

[Falcounet]

@CrazyCreator I think it's an issue with AppArmor. Do you use the DuetPi image for the SBC ?

[CrazyCreator]

@Falcounet
No ... i make all clean today
Raspi bullseye from raspi

[Falcounet]

@CrazyCreator Then try installing apparmor and try again

[CrazyCreator]

@Falcounet
I don't just have to install it. This AppArmor still needs to be configured.

Do you know what I have to do exactly? I'm not the Linux expert

[Falcounet]

@CrazyCreator DSF configure it for you. Config files are stored into /etc/apparmor.d/.
You should get /etc/apparmor.d/dsf.ExecOnMcode after the plugin installation.

Make sure you also have installed duetpluginservice

@Falcounet

I don't have this file.

But the install from the plugin is not complete, so i think the file is not created.
