ReactorNotRestartable error when running both Commando and CommandRunner

[adhirchakravarti]

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 

Enter devices separated by comma: 172.16.1.11

Enter files separated by comma. Example: /home/ubuntu/cmd1.txt: commands1.txt

Commands executed successfully on all devices.

Unfortunately this is a known issue w/ trigger.contrib.docommand that we have yet to rectify!

See: #152

Thanks for reporting this.
