Can it be (mis)used to execute custom commands? about ajenti HOT 6 OPEN

Hi @mailinglists35

You can achieve this kind of behaviour by developping your own plugin and integrating it in Ajenti.
It's also possible to set different permissions for the users.

Arnaud, at first look through the demo plugins it seems a bit complicated - I only know shell scripting.

Could you show a starting point? I could then clone and multiply to all commands that I need.

An example with running system command "/usr/bin/systemctl restart someservice" and printing it's output would be sufficiently exactly what I need.

Hello @mailinglists35

Sorry for the late reply, I did not see your answer !
There's some demo plugin with minimal examples here : https://github.com/ajenti/demo-plugins

I think it's a goog starting point for understanding how it is working. Just ask if you need help ! (i will follow your answers ;) )

yes, about those demo plugins I was referring them as too difficult to start with for someone with only bash scripting skills

from ajenti.

Each plugin contains a frontend part (javascript) and a backend part (python).
I will take an example with https://github.com/ajenti/demo-plugins/blob/master/demo_4_http/views.py, and say you want to write a new plugin named myplugin
You will need to copy the whole demo_4_http directory and replace each reference to demo_4_http into myplugin (e.g. https://github.com/ajenti/demo-plugins/blob/master/demo_4_http/plugin.yml).

But in order to achieve this, you will need ajenti-dev-multitool in order to build the javascript part (follow the readme https://github.com/ajenti/demo-plugins/tree/master ).

The backend part for your request could simply be:

import time
import subprocess
from jadi import component

from aj.api.http import url, HttpPlugin

from aj.api.endpoint import endpoint, EndpointError, EndpointReturn


@component(HttpPlugin)
class Handler(HttpPlugin):
    def __init__(self, context):
        self.context = context

    @url(r'/api/myplugin/someservice/restart')
    @endpoint(api=True)
    def handle_api_calculate(self, http_context):
        try:
            subprocess.check_output(['systemctl', 'restart', 'someservice'])
            return "Success"
        except Exception as e:
            raise EndpointError(e)
   

For the frontend:

• write a function which call the new API endpoint in https://github.com/ajenti/demo-plugins/blob/master/demo_4_http/resources/js/controllers/index.controller.coffee, like:

$scope.restart_my_service = () ->
        $http.get("/api/myplugin/someservice/restart").success (data) ->
            $scope.result = data
        .error (err) ->
            notify.error 'Restart failed', err.message
            $scope.result = null

• put a button in the html file https://github.com/ajenti/demo-plugins/blob/master/demo_4_http/resources/partial/index.html linked to this new javascript function:

<a ng:click="restart_my_service()" class="btn btn-default">Restart my service</a>

I hope it helps.
