Feel like automating some configurations, monitoring and troubleshooting on Junos? Step in Python and Junos PyEZ framework (https://techwiki.juniper.net/Projects/Junos_PyEZ). Junos PyEZ is a framework for Python which allows “quite easy” approach for performing automation and configuration tasks on Junos-platform devices. It is also easy to understand for non-programmers so you really don’t have to have deep Python understanding for basic tasks. On protocol level it uses Netconf over SSH for connecting to the device.
The requirements are Python 2.7 and Junos PyEZ framework. I have my test platform running on CentOS 6.6. CentOS 6.6 comes by default with Python 2.6 so it needs updating or new Python 2.7 version installed on the side. You can check the quick guide I wrote for installing Python 2.7 on CentOS 6.6 here: http://www.networkers.fi/blog/installing-python-2-7-on-centos-6-x/
