Hi, I installed Kali Linux version 1.0.7 64 bit, and I followed all the steps that showed in the guide. However, I ran into a problems:

+ In Iceweasle, I am able to access to google.com, yahoo.com, but I can't access to other websites, not even kali.org. For kali.org, when I do a ping request, somehow it success.

+ When I do the command : apt-get update I got and error saying could not resolve 'security.kali.org'

_ When I was installing, I didn't able to install network mirror.
_ I fixed the error network is not managed.
_ I was able to ping my default gateway as well.

*Why I can't access to other website or using the command apt-get update? Could anyone explain and help me please? Thanks in advance!
