Playing with my Juniper's router... PyEz

JUNOS PyEz is easy as pie...

Ok, may be not that easy.  But it is doable.

I was randomly browsing the net while waiting to upgrade my MX480 to the latest and greatest JUNOS 12.3R5.whatever....  I remember that I still try to learn my rope around Python and one thing leads to another... "PyEZ" on Juniper's techwiki...

I was hoping to just download the module and run off from techwiki, but unfortunately, I need to go to git to get it. Fortunately, the instruction is easy enough to do.  Only two commands to install the required modules on my Ubuntu system:

sudo pip install git+https://github.com/Juniper/ncclient.git
sudo pip install junos-eznc

My first try was unsuccessful and I got the following messages:

  Running setup.py egg_info for package lxml
    /usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'bugtrack_url'
      warnings.warn(msg)
    Building lxml version 3.3.0.
    Building without Cython.
    ERROR: /bin/sh: 1: xslt-config: not found
    
    ** make sure the development packages of libxml2 and libxslt are installed **

Not included in the instruction is that I also need to install two additional packages:

• python-dev
• libxslt1-dev

Which on my Ubuntu system, it is easy enough to do:

% sudo apt-get install python-dev
% sudo apt-get install libxslt1-dev

After I install the two packages, the installation of the pyez was very smooth.
Jeremy's example in the installation page was pretty easy enough for testing. I highly recommend you to just try it in interactive mode like I did...

And I notice that my router has been upgraded. That's it for now.
