Utilizing the command queue, you can fire multiple commands and the client will execute them one by one. All the commands are executed using a single context, so you issue multiple related commands.

To view the commands issued to a client, first select a client:

>> select 1
Then, issue the coms command to view all the commands for the client:

(Client 1) >> coms
To view the full command and it’s full output (on the coms command the output is truncated to fit the screen):

(Client 1) >> com 1


Installation

It is recommended to use a virtual environment:

Pyenv

pyenv virtualenv -p python3.6 venv
pyenv activate venv
virtualenv

virtualenv -p python3.6 venv
source venv/bin/activate
For both

pip install -r requirements.txt


Running

Create the database

python db_handler.py create
Start the server:

python run.py
Navigate with a browser to the server address

http://localhost:5000 (port can be changed)

Open the interactive shell

python shell.py
