When we talk about update, we know that the client system is downloading an update and patches from the source(online- from the network resource or offline- cd/dvd or any other secondary source). Here, we are talking about online update only. Kali Linux is relatively new and have less mirror sites, so the less the mirror sites the more online users to access the server and utilizing all the bandwidth. When you type apt-get update  on the terminal, it searches for the relative links for update from  /etc/apt/sources.list . So, more the number of links in the repository file, the more time it will consume to search for an update. Below are the few necessary steps that you can perform to fix the issue. STEPS: 1. Check if you got the right repositories in  /etc/apt/sources.list . Please remove unwanted and un-necessary repositories from the  sources.list . Click here for more. 2.

There are several open source and enterprise software program through which we can access remote system. These software becomes a necessity when you setup a remote server and do not allow direct access to the server, as because of some security measures. PuTTy is one of the major terminal emulator through which we can access a remote server. PuTTy is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet and rlogin. Here, I am going to show you how to access Kali Linux through PuTTy . My base computer is running Windows 7 and Kali Linux is installed in a VMWare Player. So we can assume that Kali Linux is installed in a remote machine, as Windows 7 and of Kali Linux is on different network now. Before we access Kali Linux through remote system, we need to make sure that ssh service is already running in Kali Linux. To check the status of ssh service. Open root terminal and type...

As kali linux is new to all of us, being a learner we all come with a new issue and try to resolve it as quickly as possible. While installing software, most of us don't know the dependency packages that are installed or removed from the system. A great feature that kali linux provide is that when we run apt  command, it checks the available package/s in the repository and accordingly asks if to install. Meanwhile, it also checks the un-necessary packages that is not required. Here is a command that removes the un-necessary packages. From the root terminal window, please type  apt-get autoremove . When you hit 'return' or 'enter'  key, it checks the packages that is to be removed from the system. Please read those packages carefully, before you make confirmation to remove it from the system.

Open root terminal window and type     apt-get remove iceweasel it removes  iceweasel   from the application menu 2. type  echo -e "\ndeb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main" | tee -a /etc/apt/sources.list > /dev/null it adds repository for the installation 3. type apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C1289A29 import the required gpg key 4. type apt-get update update the required package 5. type apt-get install firefox-mozilla-build install mozilla ...
