Setting up RDP with Xfce
Kali Linux is supported on many different devices and systems. On some of those systems, you may only get a bare-bones install and occasionally may not have direct access to a GUI such as with WSL or Docker. One simple way to get access to a GUI for Kali is by installing Xfce and setting up RDP. This can be done either manually or with the script provided here, and can be seen below:
#!/bin/sh echo "[i] Updating and upgrading Kali (this will take a while)" apt-get update apt-get dist-upgrade -y echo "[i] Installing Xfce4 & xrdp (this will take a while as well)" apt-get install -y kali-desktop-xfce xorg xrdp echo "[i] Configuring xrdp to listen to port 3390 (but not starting the service)" sed -i 's/port=3389/port=3390/g' /etc/xrdp/xrdp.ini
Before we can start the process of setting up Xfce and RDP, we must first acknowledge some differences with certain systems Kali is on. The first is Docker. To use this setup with Docker, we must supply a launch command like the following:
docker run -p 3390:3390 --expose=3390 --tty --interactive kalilinux/kali-rolling /bin/bash
For additional usage on Docker, such as how to resume an exited container, please read using Kali Docker images.
For AWS, we must be sure to allow our IP to access the proper ports when we set up the machine.
To use the script we do the following:
# If on Docker, run the following command first before continuing: [email protected]:/$ apt update && DEBIAN_FRONTEND=noninteractive apt install -y wget kali-linux-headless [email protected]:~$ wget https://gitlab.com/kalilinux/recipes/kali-scripts/-/raw/main/xfce4.sh [email protected]:~$ [email protected]:~$ chmod +x xfce4.sh [email protected]:~$ [email protected]:~$ sudo ./xfce4.sh [email protected]:~$
Setting this up manually will provide more control over what configuration is done, but also will take a bit longer.
If you are using WSL, dbus-x11 needs to be installed next for xrdp and xfce to connect:
[email protected]:~$ sudo apt install -y dbus-x11 [email protected]:~$
After you set up Xfce and RDP, you need to start the service:
# If on AWS [email protected]:~$ sudo systemctl enable xrdp --now [email protected]:~$ # If on WSL or Docker [email protected]:~$ sudo /etc/init.d/xrdp start [email protected]:~$
In the case of AWS, you will need to change the password to the default ‘kali’ account before connecting. This can be done with the following command:
[email protected]:~$ echo kali:kali | sudo chpasswd [email protected]:~$
If you are using Docker, you will need to create a new user. You can do this with adduser
[email protected]:~$ adduser kali [...] [email protected]:~$
You can then connect with a RDP client to that system. Keep in mind the port that is being used. If you used the script, the port would be 3390. In the case of WSL and Docker, the IP would be 127.0.0.1:3390 that you would wish to connect to from your windows system (or the host systems IP from a separate computer). In the case of AWS, the IP would be the same as you use to connect via SSH.
You may encounter the error
Authentication Required to Create Managed Color Device when trying to connect. Do the following to fix this issue.
