ReactorNotRestartable error when running both Commando and CommandRunner #311
Description
Hello,
Let me start by saying thanks for creating trigger! I'm new to both trigger and python, so if this is the wrong place to post this issue, please let me know so that I may post it elsewhere.
I've just started using trigger am trying to accomplish a simple task of sending configuration commands to a Cisco router using the CommandRunner object, followed by sending verification commands using Commando to retrieve and print output. If I use only 1 instance (either Commando or CommandRunner), there are no issues and the code executes well. However using both causes that error.
Am I missing something?
Error:
ubuntu@ubuntu-VirtualBox:~/MyFiles/Cisco$ ls
Commando_Cisco.py CommandRunner2_Cisco.py CommandRunner_Cisco.py commands1.txt verification1.txt
ubuntu@ubuntu-VirtualBox:~/MyFiles/Cisco$ python CommandRunner2_Cisco.py
