How it works?
* Kali Linux with XFCE Desktop Environment in Windows Subsystem for Linux (WSL)
* VcXsrv X Server for Windows is doing the hard GUI lifting
* XFCE is started natively in WSL and displayed by VcXsrv

Install Voodoo-Kali:
1, Enable WSL and install Kali Linux from the Microsoft Store. Read Install Kali Linux desktop on Windows 10 from Microsoft Store

2, To start Kali Linux in Windows 10, open Command Prompt and enter the command: kali

3, Enter this commands:
  apt install wget -y
  wget https://raw.githubusercontent.com/Re4son/WSL-Kali-X/master/install-WSL-Kali-X
  bash ./install-WSL-Kali-X

4, Download and install VcXsrv Windows X Server from SourceForge

5, Start VcXsrv, accept change in firewall rules, exit VcXsrv

Run Voodoo-Kali:
Start kali in Windows as normal user (that's default), and launch Voodoo-Kali:
* as normal user: ./start-xfce
* as root: sudo /root/xtart-xfce

Run Kali Desktop in an RDP session:
In Kali Linux WSL, type: sudo /etc/init.d/xrdp start
In Windows 10, open Run and enter mstsc.exe and connect to "127.0.0.1:3390"

Status: Voodoo-Kali is in its infancy and it is far from being elegant. I'm working on it though and step by step I'll push out improvements. Below a snippet of the To-Do list:
* Clean up and comment the scripts
* Make for a cleaner exit
* Better error handling and dependency checking (get rid of sleep, etc.)
* Improve stability of Java programs
* Improve the looks??
* …

Any help is truly appreciated, in any shape or form – from tips to pull requests.
Why don't you join the forums to discuss?

The Zed Attack Proxy team is pleased to announce two recently released initiatives:

ZAP In Ten

The team have just launched a new series of videos called 'ZAP in Ten' in conjunction with AllDayDevOps.

ZAP in Ten is a series of short form videos featuring Simon Bennetts, project lead of the OWASP Zed Attack Proxy (ZAP) project. Each video highlights a specific feature or resource for ZAP.

ZAP API Docs

As part of OWASP's participation in Google's Season of Docs, the ZAP project has had @sshniro working on API documentation. The first iteration of the documentation is now live. It includes Java, Python, and shell example snippets all presented in a responsive and accessible design. Which we will continue to build on in the future.

Big thanks to Nirojan for his efforts on this wonderful initiative! Congratulations and thanks to Google Open Source for helping to bring the open source and technical writer communities together!

Welcome back to Linux Command Line Hackery series, I hope you've enjoyed this series so far and would have learned something (at least a bit). Today we're going to get into user management, that is we are going to learn commands that will help us add and remove users and groups. So bring it on...

Before we get into adding new users to our system lets first talk about a command that will be useful if you are a non-root user.

Command: sudo
Syntax: sudo [options] command
Description: sudo allows a permitted user to execute a command as a superuser or another user.

Since the commands to follow need root privileges, if you are not root then don't forget to prefix these commands with sudo command. And yes you'll need to enter the root password in order to execute any command with sudo as root.

Command: useradd
Syntax: useradd [options] username
Description: this command is used for creating new user but is kinda old school.
Lets try to add a new user to our box.
[Note: I'm performing these commands as root user, you'll need root privileges to add a new user to your box. If you aren't root then you can try these commands by prefixing the sudo command at the very beginning of these command like this sudo useradd joe. You'll be prompted for your root password, enter it and you're good to go]

useradd joe

To verify that this command has really added a user to our box we can look at three files that store a users data on a Linux box, which are:

/etc/passwd -> this file stores information about a user separated by colons in this manner, first is login name, then in past there used to be an encrypted password hash at the second place however since the password hashes were moved to shadow file now it has a cross (x) there, then there is user id, after it is the user's group id, following it is a comment field, then the next field contains users home directory, and at last is the login shell of the user.

/etc/group -> this file stores information about groups, that is id of the group and to which group an user belongs.

/etc/shadow -> this file stores the encrypted password of users.

Using our command line techniques we learned so far lets check out these files and verify if our user has been created:

cat /etc/passwd /etc/group /etc/shadow | grep joe

In the above screenshot you can notice an ! in the /etc/shadow, this means the password of this user has not been set yet. That means we have to set the password of user joe manually, lets do just that.

Command: passwd
Syntax: passwd [options] [username]
Description: this command is used to change the password of user accounts.
Note that this command needs root privileges. So if you are not root then prefix this command with sudo.

passwd joe

After typing this command, you'll be prompted password and then for verifying your password. The password won't show up on the terminal.
Now joe's account is up and running with a password.

The useradd command is a old school command, lets create a new user with a different command which is kinda interactive.

Command: adduser
Syntax: adduser [options] user
Description: adduser command adds a user to the system. It is more friendly front-end to the useradd command.

So lets create a new user with adduser.

adduser jane

as seen in the image it prompts for password, full name and many other things and thus is easy to use.

OK now we know how to create a user its time to create a group which is very easy.

Command: addgroup
Syntax: addgroup [options] groupname
Description: This command is used to create a new group or add an existing user to an existing group.

We create a new group like this

addgroup grownups

So now we have a group called grownups, you can verify it by looking at /etc/group file.
Since joe is not a grownup user yet but jane is we'll add jane to grownups group like this:

addgroup jane grownups

Now jane is the member of grownups.

Its time to learn how to remove a user from our system and how to remove a group from the system, lets get straight to that.

Command: deluser
Syntax: deluser [options] username
Description: remove a user from system.

Lets remove joe from our system

deluser joe

Yes its as easy as that. But remember by default deluser will remove the user without removing the home directory or any other files owned by the user. Removing the home directory can be achieved by using the --remove-home option.

deluser jane --remove-home

Also the --remove-all-files option removes all the files from the system owned by the user (better watch-out). And to create a backup of all the files before deleting use the --backup option.

We don't need grownups group so lets remove it.

Command: delgroup
Syntax: delgroup [options] groupname
Description: remove a group from the system.

To remove grownups group just type:

delgroup grownups

That's it for today hope you got something in your head.
