Deploying Kali over Network PXE/iPXE Install

Table of Contents

Booting and installing Kali Linux over the network (PXE) can be useful from a single laptop install with no CDROM or USB ports, to enterprise deployments supporting pre-seeding of the Kali Linux installation.

We will cover three different ways of using PXE. The first way will be how to manually set up PXE with dnsmasq. The second will be a partially-automated way using Docker. The final way will utilize netbootxyz, which hosts the PXE files and uses a separate DNS server to properly direct computers. Please utilize the Table of Contents to quickly navigate to the method you want to follow.

Manually setting up a PXE Server with dnsmasq

First, we need to install dnsmasq to provide the DHCP/TFTP server and then edit the dnsmasq.conf file:

[email protected]:~$ sudo apt install -y dnsmasq
[email protected]:~$
[email protected]:~$ sudo vim /etc/dnsmasq.conf
[email protected]:~$

In dnsmasq.conf, enable DHCP, TFTP and PXE booting and set the dhcp-range to match your environment (we are using If needed you can also define your gateway and DNS servers with the dhcp-option directive as shown below:


With the edits in place, the dnsmasq service needs to be restarted in order for the changes to take effect:

[email protected]:~$ sudo systemctl restart dnsmasq
[email protected]:~$

Download Kali PXE Netboot Images

Now, we need to create a directory to hold the Kali Linux Netboot image and download the image we wish to serve:

[email protected]:~$ sudo mkdir -p /tftpboot/
[email protected]:~$

# 64-bit:
[email protected]:~$ sudo wget -P /tftpboot/
# 32-bit:
[email protected]:~$ sudo wget -P /tftpboot/

[email protected]:~$ sudo tar -zxpf /tftpboot/netboot.tar.gz -C /tftpboot
[email protected]:~$
[email protected]:~$ sudo rm -f /tftpboot/netboot.tar.gz
[email protected]:~$

Configure Target to Boot From Network

With everything configured, you can now boot your target system and configure it to boot from the network. It should get an IP address from your PXE server and begin booting Kali Linux.

Post Installation

Now that you’ve completed installing Kali Linux, it’s time to customize your system. The General Use section has more information and you can also find tips on how to get the most out of Kali Linux in our User Forums.

One last thing we need to do if we want to use this system in the future is set up a cron job to pull in the new Netboot images regularly in case of kernel updates. We will create a simple script for this purpose named


## We input our desired path for the PXE image to be saved to

## We remove the previous directory containing the PXE image and download the newest version
rm -rf $tftp/
mkdir -p $tftp/
wget$arch/current/images/netboot/netboot.tar.gz -P $tftp/
tar -zxpf /tftpboot/netboot.tar.gz -C $tftp
rm -f $tftp/netboot.tar.gz

We save this script to /opt and are sure to set it’s permissions so you can only edit it with root or sudo. An example of this is to set the file to 770 or 700 with chmod, and set it to root:root with chown.

We can now add it to a cron job:

[email protected]:~$ sudo crontab -e
0 5 * * 2 /opt/
[email protected]:~$

Using Docker and dnsmasq to automate setup of a PXE server

Docker file and dnsmasq.conf

The docker file we will use looks like the following:

FROM kalilinux/kali-rolling

ENV HOME /root

RUN apt update && apt install -y init

CMD ["/sbin/init"]

RUN apt install -y dnsmasq syslinux nginx iproute2 vim wget net-tools less

RUN rm /etc/dnsmasq.conf

COPY dnsmasq.conf /etc/dnsmasq.conf

RUN mkdir -p /tftpboot/

RUN wget -P /tftpboot/

RUN tar -zxpf /tftpboot/netboot.tar.gz -C /tftpboot

RUN rm -f /tftpboot/netboot.tar.gz

Before we can build this container we need to create the file dnsmasq.conf. We use the following options:


Launch Docker container

We run the following commands to create our Docker container. Please note --privileged=true and --network host is necessary for the port mapping to work properly:

[email protected]:~$ docker build --tag="kali/systemd" .
[email protected]:~$ docker run -it -d --privileged=true --network host kali/systemd /sbin/init
[email protected]:~$ docker exec -it docker-container-id bash


Once booted and connected, we must run the following command:

[email protected]:~$ sudo systemctl restart dnsmasq

We are now good to go!

Preseeding PXE

Preseed file

We can use the following preseed file to automatically install our Kali instance. Be sure to change package selection, user information, region information, and hard drive to match what you are using. Alternatively, should you want to be prompted for any of those, just comment out the line:

# Package selection
d-i pkgsel/include string kali-linux-default kali-desktop-xfce

# User information
d-i passwd/user-fullname string kali
d-i passwd/username string kali

Preseed integration to initrd

To incorporate this into our initrd to automatically run we must do the following:

[email protected]:~$ gunzip initrd.gz
[email protected]:~$ echo preseed.cfg | cpio -H newc -o -A -F initrd
[email protected]:~$ gzip initrd
[email protected]:~$ systemctl restart dnsmasq

Using netbootxyz to host our PXE files

To install netbootxyz we will follow the official documentation. Using this method will allow us to set up a server and use our existing DHCP server to point to it, rather than creating a new DHCP server.
