1. First thing first ...what's ESSPEE.So friends who are aware of whats Backtrack R3....ESSPEE is a derivative of BackTrack 5, based on Ubuntu 12.04. Designed for users who wish to use only free software. It is packed with featured security tools with stable configurations....and now for those of you who wish to know the expanded form of ESSPEE ...its EXTREME SECURITY SCANNING PENETRATION TESTING & EXPLOITATION ENVIRONMENT.....:-)

So after downloading this from here...and after installing I came across a small issue of eth0 NIC not being detected unlike regularly where it gets detected automatically vide a DHCP config.So the answer is a small tweak that is required while selecting the Mac address of the eth0 as shown in the screen shot below :
