my guide to build a python development VM on your local windows machine to combine both the efficiency of linux and the usability of windows laptop – I use pycharm as an example of python IDE but you can use any IDE that support the remote deployment.
For more info about remote deployment function please see the below link
As you notice from previous configuration. We have to configure the unit 1 with static VLAN (800) to create only ONE SUBSCRIBER INTERFACE . However in real world scenario this not necessarily the case. we need to make MX check the incoming vlan id from DSLAM and handle the creation of both VLANS and Units that hold the PPPoE sessions. BTW, Here’s a golden rule. One Vlan per Unit!
You can find below the interface structure in dynamic configuration. The physical interface is ae(Active Ethernet) and beneath it the auto-configure command that “instantiate” the VLAN and SVLAN from dynamic-profile

Have you ever wanted to develop a Python or Web application for Linux from your laptop running Windows 7 or MAC OS X? Do you want to run your code that will be published to whole world but afraid from the dependencies mismatch between your laptop and production server?

You may have an IT team in your company who believe company productivity will be boosted if company disallow access to social media , streaming or even the soundcloud. Although some recent studies show that productivity has nothing to do with such sites
Don’t get me wrong, but I hate to be restricted or not having access to what I want, of course I won’t visit illegal sites or hiding my gampling history! using the corporate network but also I need some level of freedom to perform well. I will manage my own time!
Anyways whatever your final goal, make sure you’re not breaking any corporate policies
So let’s start
First here’s the topology and the normal call flow for Enterprise Network
What we will try to accomplish is manipulate the corporate gateway and establish an SSH tunnel back to our home network (where everything is accessible from there and free!) then we will redirect our browsing traffic to home network back and forth.
No just that, we will enhance the tunneling by connecting our home router to DDNS provider
From firewall perspective, we just established an innocent SSH connection to somewhere in the internet
1-Modem (Home Router) that support Port Forwarding (most routers nowdays do)
2-VMware to run squid proxy server and SSH over Centos Machine
3-DDNS account (www.noip.com is my favorite, However if your purchased an static IP from your ISP then this step is not necessary but remember this solution is for poor guys J )
Client in Corporate
4-MobaXterm (to establish SSH tunnel back to VMware)

Diameter is an authentication, authorization, and accounting protocol. used primarily for Service provider networks . It evolved from and replaces the much less capable RADIUS protocol that preceded it.
in this presentation I will try to familiarize you with the new AAA protocol and deep dive into the diameter protocol details, Credit Control Application (Gx,Gy and GZ) and sample use case for peering Sandvine PTS (Working as PCEF) with freePCRF.server and finally introduce you with seagull, a popular test tool to test different diameter-based scenarios
Hope You like it.
