My goal is to install Juniper's PyEZ on my Macbook Air so that I can do some work while hanging out with friends. As many of my friends do, we hang out having coffee for awhile and then the topic of discussion usually turns into technical. From than on, if enough people curious, it turns into a mini-hackaton. LOL. I think we spend too much time on this and not enough on non-technical thing. Getting a life is probably is a good thing too *giggle*
As a tools, my 11" MBA is hard to beat. The keyboard is full size - except for the tiny arrow keys on the right. The screen is more than adequate. The battery life is awesome. And it is light. Not as light as the new Macbook, but it is light enough. An at less than $999, it is hard to beat.
Anyway, my note for today is how to install "Juniper's PyEZ" on my Macbook Air. Let spend some time on the PyEZ. This post contains the first part of my installation which covers getting most of the Python library in place. The next blog will continue with the installation.
Juniper's PyEZ
PyEZ is a Python power-shell that you can use to interact with Juniper's routers. It is based on Netconf (see RFC6241) Supposedly it provides a consistent interface to a router such that you can - at least in theory - using a unify program/interface to talk to elements in your multi-vendor network. (commentary... you can see how well it works such that there is another movement to unify further via openconfig.org)
I checked out Juniper's web site and it listed the requirement of installing:
- Xcode
- pip
The next step is to install "PyEZ" using "pip install junos-pyez". Unfortunately, this won't work cuz I got an error while compiling it. Here's my error on the screen: (Note the cute ASCII scroll bar, it's so '80s LOL.)

Unfortunately, after all these works, it is not enough. The problem is that "easy_install" can't file libxml version number. Ok, it is a good practice to make sure you have the right thing install, but wow, how come it doesn't work?
A little more googling and I found out that there is actually a better instruction on how to install the PyEZ. I found it on Juniper's github page -
https://github.com/Juniper/py-junos-eznc/blob/master/INSTALL-OSX.md
I probably can be shameless and copy the content here. However, I don't feel like doing this today. LOL. So may be when I don't have anything better to do I'll do that.Anyway, you follow the instruction on that page and you should be able to install your PyEZ. I haven't finished the installation, yet. So I'm sure I will post more stuffs in a couple of days.
Later Loves.
