network topology
I will be setting up an Ubuntu 22.04 LTS machine (PXE boot server) as a PXE boot server using iPXE firmware. The PXE boot server will also function as a DHCP and TFTP server. They are required for PXE boot to work. Just to demonstrate how it all works, I'm going to show you how to configure the PXE boot server to boot the Ubuntu Desktop 22.04 LTS Live installer on a computer (PXE-client) so you can install Ubuntu Desktop 22.04 LTS on it without any CD/DVD drive or USB device.
Configuring a static IP address on Ubuntu Server 22.04 LTS
Before proceeding, it's best to configure the PXE boot server with a fixed/static IP address. In this section, I will show you how to configure a static/fixed IP address on Ubuntu Server 22.04 LTS.
To configure a fixed/static IP address on Ubuntu Server 22.04 LTS, open the netplan configuration file/etc/netplan/00-installer-config.yamlwith himnanotext editor as follows:
PSsudo nano /etc./red plan/00-installer-config.yaml
By default, DHCP is enabled for the network interface.ens33, as you can see in the screenshot below.
To set a static/fixed IP address192.168.0.130(What else/24netmask, gateway address192.168.0.1and DNS nameservers1.1.1.1 e 8.8.8.8), change the settings of theens33network interface as follows. Once finished, press<Ctrl> + Xfollowed byand and <Enter>to save the netplan configuration file.
To apply the changes, run the following command:
PSsudoapply network plan
A static/fixed IP address192.168.0.130 must be set to ens33network interface, as you can see in the screenshot below.
PSipone
It should also be able to resolve DNS names to IP addresses as you can see in the screenshot below.

Configuring a Static IP Address in Ubuntu Desktop 22.04 LTS
Even if you're using Ubuntu Desktop 22.04 LTS instead of Ubuntu Server 22.04 LTS to set up a PXE boot server, it's still a good idea to set up a fixed/static IP address on your computer. In this section, I will show you how to configure a static/fixed IP address in Ubuntu Desktop 22.04 LTS.
To find the name of the currently active Network Manager connection, run the following command:
PSnmcli connection show
The name of the currently active Network Manager connection isWired connection 1.
To set a static/fixed IP address192.168.0.130(What else/24 network mask, input direction192.168.0.1and DNS nameservers1.1.1.1 e 8.8.8.8) for network manager connectionwired connection 1, run the following command:
PSmodifying nmcli connection"Wired connection 1"ipv4.método manual ipv4.addresses 192.168.0.130/24gw4 192.168.0.1 ipv4.dns 1.1.1.1,8.8.8.8
For the changes to take effect, run the following command:
PSactive nmcli connection"Wired connection 1"
A static/fixed IP address192.168.0.130must be set to theens33network interface, as you can see in the screenshot below.
PSipone
It should also be able to resolve DNS names to IP addresses as you can see in the screenshot below.
PSwhistle -c3google.com
(Optional) Preparing Ubuntu Desktop 22.04 LTS to install a DNS server
On Ubuntu Desktop 22.04 LTS, NetworkManager will run asystemd-resueltoservice that will act as a local DNS caching server. Thesystemd-resueltoservice uses theUDP port 53, the same asdnsmasq🇧🇷 So while theservice resolved by systemdIs running,dnsmasqdoes not work. If you are using Ubuntu Desktop 22.04 LTS to configure a PXE boot server, you must disable and stop thesystemd-resueltoservice before installing/running dnsmasq.
stop theservice resolved by systemd, run the following command:
PSsudosystemctl stop systemd-resuelto
Also, remove thesystemd-resueltoservice from system startup so that it is no longer automatically started at boot time.
PSsudosystemctl deshabilitar systemd-resuelto
Remove the symbolic link from/etc/resolv.conf filewith the following command:
PSsudo disconnect /etc./resolv.conf
create a new/etc/resolv.conf filewith himnanotext editor as follows:
PSsudo nano /etc./resolv.conf
Write the following lines in the/etc/resolv.conf file.
Once finished, press<Ctrl> + X followed by Y and <Enter>to save the/etc/resolv.conf file.
It should also be able to resolve DNS names to IP addresses again, as you can see in the screenshot below.

Creating the necessary directory structure
In this section, I'll create all the necessary directories for PXE boot (using iPXE firmware) to work.
I planned the directory structure as follows:
/pxe boot
- context/
- firmware/
- os-images/
Nodirectory /pxeboot/config/, I will store all iPXE boot configuration files.
No/pxeboot/firmware/ directory, I will store all iPXE bootable firmware files.
Nodirectory /pxeboot/os-images/, I'll create a separate subdirectory for each of the Linux distributions (which I want to PXE boot) and store the contents of the ISO images for those Linux distributions there. For example, to PXE boot Ubuntu Desktop 22.04 LTS, you can create a directoryubuntu-22.04-desktop-amd64/ in directory /pxeboot/os-images/and store the contents of the Ubuntu Desktop 22.04 LTS ISO image in that directory.
To create all necessary directory structures, run the following command:
PSsudo mkdir -pv /pxe boot/{config,firmware,os-images}
All directory structures required for PXE booting must be created.
Download iPXE source code and build iPXE on Ubuntu 22.04 LTS
In this section, I'll show you how to download the iPXE source code and compile it on Ubuntu 22.04 LTS so we can use it for PXE booting.
First, refresh the APT package repository cache with the following command:
PSsudoproper update
To install the necessary build dependencies for iPXE, run the following command:
PSsudofitinstall not pcbuild-essential liblzma-dev isolinuxgit
To confirm the installation, pressY and then press <Enter>.
All necessary packages will be downloaded from the Internet. It will take a while to complete.
Once the packages are downloaded, they will be installed one by one. It will take a few seconds to complete.
At this point, all required dependency packages should be installed.
Now navigate to the~/Downloadsdirectory as follows:
PSCD~/downloads
Clone the iPXE GitHub repository to your Ubuntu 22.04 LTS machine as follows:
PSclonehttps://github.com/ipxe/ipxe.git
The iPXE GitHub repository needs to be cloned.
a new directoryipxe/must be created in~/Downloadsdirectory, as you can see in the screenshot below.
PSls -lh
Navigate to theipxe/src/directory as follows:
PSCDipxe/origin
You should see many directories that contain the iPXE source code.
PSls -lh
To configure iPXE to boot automatically from an iPXE init script stored ondirectory /pxeboot/config/from your computer, you will need to create an iPXE init script and incorporate it into the iPXE firmware when compiling it.
Create an iPXE init scriptbootconfig.ipxe and open it with nanotext editor as follows:
PSnanobootconfig.ipxe
Write the following lines of code in thebootconfig.ipxe file.
#!ipxe
dhcp
Cadena tftp://192.168.0.130/context/boot.ipxe
When finished, save the file by pressing<Ctrl> + X followed by Y and <Enter>.
TO USE: Here,192.168.0.130is the IP address of my Ubuntu 22.04 LTS machine that I am configuring as a PXE boot server (PXE boot server🇧🇷 It will be different for you.
To compile iPXE BIOS and UEFI firmware and embed thebootconfig.ipxe iPXE boot scripton compiled firmwares, run the following command:
PSDoescompartment/ipxe.pxe container/undioly.kpxe bin/undioly.kkpxe bin/undioly.kkkpxe bin-x86_64-efi/ipxe.efiEMBEDDED=bootconfig.ipxe
iPXE boot firmware files are being compiled for BIOS and UEFI systems. It will take a few seconds to complete.
iPXE boot firmware files for BIOS and UEFI systems are being compiled...
iPXE boot firmware files for BIOS and UEFI systems are compiled at this point.
Copy compiled iPXE firmwares to /pxeboot/firmware directory
After the iPXE boot firmware files are compiled, copy them to the/pxeboot/firmware directoryof your Ubuntu 22.04 LTS PXE boot server so that PXE client computers can access them via TFTP.
PSsudo c.p. -vcompartment/{ipxe.pxe,undionly.kpxe,undionly.kkpxe,undionly.kkkpxe}bin-x86_64-efi/ipxe.efi/pxe boot/firmware/
The iPXE boot firmware files must be copied to the/pxeboot/firmware directory.
Once the iPXE boot firmware files are copied to the/pxeboot/firmware directory, the directory structure of the/pxeboot directoryshould look like shown in the screenshot below.
Here the iPXE boot firmware filesipxe.pxe, undioly.kpxe, undioly.kkpxe e undioly.kkkpxethey are for PXE booting on BIOS systems. The iPXE boot firmware fileipxe.efi is for PXE booting on UEFI systems.
For more information on iPXE boot firmware files, read theiPXE Compilation for BIOS Based Motherboards and iPXE Compilation for UEFI Based Motherboards from ArticleHow to Configure Synology NAS as PXE Boot Server to Boot Linux Installation Images Over Network with iPXE (BIOS and UEFI Version) em linuxhint. com.
Installing and Configuring a DHCP and TFTP Server on Ubuntu 22.04 LTS
For PXE boot to work, you will need a working DHCP and TFTP server on your computer. There are many DHCP and TFTP server software. But in this article I will usednsmasq. dnsmasqit is primarily a DNS and DHCP server that can also be configured as a TFTP server.
No Ubuntu 22.04 LTS,dnsmasqit is not installed by default. But it is available in Ubuntu 22.04 official package repository and you can install it with APT package manager very easily.
installdnsmasqon Ubuntu 22.04 LTS run the following command:
PSsudofitinstall not pcdnsmasq-y
dnsmasq must be installed.
Let's create a new dnsmasq. Then, rename the original./etc/dnsmasq.conf file to /etc/dnsmasq.conf.backupAs follows:
PSsudo m.v. -v /etc./dnsmasq.conf/etc./dnsmasq.conf.backup
Create an empty dnsmasq configuration file/etc/dnsmasq.confwith the following command:
PSsudo nano /etc./dnsmasq.conf
Write the following lines in the dnsmasq configuration file/etc/dnsmasq.conf:
Interface=ens33
interfaces de enlace
domain=linuxhint.local
dhcp-rango=ens38,192.168.0.180,192.168.0.200,255.255.255.0,8h
dhcp-option=option:router,192.168.0.1
dhcp-option=option:dns-server,1.1.1.1
dhcp-option=option:dns-server,8.8.8.8
habilitar-tftp
tftp-root=/pxe boot
# boot configuration for BIOS systems
dhcp-match=set:bios-x86,option:client-arch,0
dhcp-boot=etiqueta:bios-x86,firmware/ipxe.pxe
# boot configuration for UEFI systems
dhcp-match=set:efi-x86_64,option:client-arch,7
dhcp-match=set:efi-x86_64,option:client-arch,9
dhcp-boot=etiqueta:efi-x86_64,firmware/ipxe.efi
The final configuration file should look like the following screenshot.
To save the dnsmasq configuration file/etc/dnsmasq.conf, press<Ctrl> + X followed by Y and <Enter>.
Here,ens33is the name of the network interface for which DHCP¹ is enabled.
I configured the DHCP server to assign IP addresses in the range192.168.0.180-192.168.0.200on PXE boot clients. Thethe router/gateway address is 192.168.0.1🇧🇷 DNS servers are1.1.1.1 e 8.8.8.82.
TO USE: If you don't know the network interface name of your Ubuntu 22.04 LTS machine, you can run theipa command to discover.
These 2 sections are used to detect whether a PXE client is BIOS or UEFI based.
If a PXE client is BIOS-based, the DHCP server serves the iPXE firmware file/pxeboot/firmware/ipxe.pxe¹.
If a PXE client is UEFI based, the DHCP server serves the iPXE firmware file/pxeboot/firmware/ipxe.efi².
For the changes to take effect, restart thednsmasqserver as follows:
PSsudosystemctl reiniciar dnsmasq
To check if thednsmasqthe service isrun, run the following command:
PSsudosystemctl status dnsmasq
As you can see, thednsmasq service is running🇧🇷 So it's configured correctly.
Installing and Configuring NFS Server on Ubuntu 22.04 LTS
Usos do Ubuntu Desktop 22.04 LTSCasperto start the live installation mode.Casperit only supports PXE boot over NFS protocol. Other Linux distributions like Fedora, CentOS/RHEL also support PXE boot via NFS protocol. Therefore, to boot Ubuntu Desktop 22.04 LTS and many other Linux distributions via PXE, you must have a fully functional NFS server accessible over the network.
To install NFS server on Ubuntu 22.04 LTS, run the following command:
PSsudofitinstall not pcNFS-kernel-servidor
To confirm the installation, pressY and then press <Enter>.
The NFS server must be installed.
Open the NFS server configuration file/etc/exportsAs follows:
PSsudo nano /etc./export
to share the/pxeboot directoryvia NFS, add the following line to the end of the /etc/exports file:
/pxe boot*(Ro,synchronize,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)
Once finished, press<Ctrl> + X followed by Y and <Enter>to save the NFS configuration file/etc/exports.
To make the new NFS share/pxeboot available, run the following command:
PSsudoexportfs-do

How to set up PXE boot in Ubuntu? ›PXE Booting Ubuntu Desktop 22.04 LTS Live Installer
Now, boot any computer on the network via PXE, and you should see that the iPXE firmware is being used for the PXE boot process. Once the iPXE firmware is initialized, you should see the following boot menu. Select Install Ubuntu Desktop 22.04 LTS and press <Enter>.
PXE uses DHCP ports and TFTP to download the binary files. For TFTP and DHCP, you need to enable ports 67, 69, and 4011. The TFTP and multicast servers use ports in the range 64001 through 65000 by default.
How do I know if PXE boot is enabled? ›Test whether the device can start when it's plugged into a switch on the same subnet as the PXE-enabled DP. If it can, the issue likely involves the router configuration. Make sure that the DHCP (67 and 68), TFTP (69), and BINL (4011) ports are open between the client computer, the DHCP server, and the PXE DP.
What is UEFI PXE booting? ›UEFI PXE Boot Configuration. PXE is used to execute an operating system's bootstrap program using a network connection. The PXE Client sends a DHCP request with PXE specific options. The DHCP server response contains the Network Bootstrap Program (NBP) filename and a list of TFTP boot servers.
Is PXE boot enabled by default? ›Disabling PXE boot
PXE is enabled by default on all computers. However, it can also be disabled. The disabling procedure varies by vendor. But in general, PXE can only be disabled from the BIOS (Basic Input Output System) interface.
From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Network Options > Network Boot Options > UEFI PXE Boot Policy and press Enter. Select a setting and press Enter.
How do you initiate a PXE boot? ›
- During startup, press and hold or continuously press F2 to enter the BIOS Setup Utility screen.
- Select PXE Device Enable, press Enter, and select Enable from the displayed dialog box. Press Enter to confirm your selection, and press F10 to save the settings and exit.
- Target Machine (either bare metal or with boot sector removed) is booted.
- The Network Interface Card (NIC) of the machine triggers a DHCP request.
- DHCP server intercepts the request and responds with standard information (IP, subnet mask, gateway, DNS etc.).
If the device does not receive an IP address, which happens when there is no DHCP server on the network or when the DHCP server is not responding, the device assigns itself an address. Auto IP addresses always follow this pattern: 169.254. x.y, where x and y are any two numbers between 0 and 255.
What would happen if you don't have a DHCP server installed? ›Dynamic Host Configuration Protocol (DHCP) is a core network service that makes it easy to manage the TCP/IP settings of the computers on your network. Without DHCP, you'd need to go to each computer and manually assign it an IP address, subnet mask, default gateway and other network settings.
What DHCP options are needed for PXE boot? ›In the PXE booting process, after the client receives the PXE answer it needs to go to the next step, which is to download a boot environment. This is where DHCP options 66 and 67 come in. Option 66 tells the PXE booted client what the Boot server IP is and option 67 is the Boot file that needs to be loaded.
Can you PXE boot a server? ›Preboot Execution Environment (PXE) Boot Server. A Preboot Execution Environment(PXE) is a client-server interface that allows computers in a network to be booted from the server before deploying the obtained PC image in local and remote offices, for PXE-enabled clients.
