The Poor Man VPN

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

Tools Used

Home Network

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)

5- Browser

Install CUCM 9.1 Boot error

Recently I got an ISO image for CUCM 9.1(UCSInstall_UCOS_9.1.2.12900-11.sgn.iso) and I intend to play around with it cause I have a project with a customer and he need to install CUCM on a UCS server. I tried to install it in my VMWare Workstation but I get the following error after I fire the VM.

it seems that the ISO wasn’t bootable…hmmm
