But this github post makes for an excellent demonstration of different configuration options. Main.ipxe has an incredible amount of flexibility for what it is, so much so that I won’t be covering everything you can make it do. This is the file fetched by iPXE after the chainload operation takes place. The menu is composed of a script file you will have to write from scratch to suit your needs. Your NIC → DHCP → TFTPs iPXE → which chainloads main.ipxe (the menu below). Main.ipxe is the menu that appears with your options after booting from the network. You should now be able to visit the /pxe-boot directory from the web browser of any PC on the LAN by typing the servers IP in the URL box. Restart the service: systemctl restart apache2 If you opted for ISC-DHCP-SERVER modify the configuration file /etc/dhcp/nf Copy/Paste the following config: subnet 192.168.0.0 netmask 255.255.255.0 /access.log combined Restart the DNSMASQ service: systemctl restart dnsmasq ISC-DHCP-SERVER Instead it gets an IP leased from the existing network router and forwards it to the requesting client. It will service DHCP requests from network clients but it won’t lease IP’s of it’s own. In this configuration DNSMASQ acts as a ProxyDHCP server. NOTE: Change the IPs to match the IP assigned to the Server/VM Pxe-service=X86-64_EFI, "Boot from network", ipxe.efi Pxe-service=X86PC, "Boot from network", undionly.kpxe If you opted for DNSMASQ modify the configuration file /etc/nf. You only need to install one or the other: apt install dnsmasq However ISC-DHCP-SERVER is adequate too if you’re willing to make it the DHCP server and just have it point clients to the network’s Default Gateway. If you have a pre-existing network w/ a router DNSMASQ will make for an easy setup. Depending on your network setup they both have pros & cons. There are two packages that can be used in this application. I’m going to be demonstrating two features of iPXE.īoth of these features require the pre-configuration of:įor most of these demonstrations I’ll be using Ubuntu Server 20.04 but if you know how to make it work on another distro that is entirely at your discretion. Great! If not, don’t hesitate to ask for help. If you already understand all of these concepts. The utilization of iPXE requires the coordination of several network protocols/features which include but aren’t limited to: I want to add my two cents by providing as complete of documentation as I can on the working configurations I’ve achieved so that prosumers and home lab enthusiasts might be able to integrate or otherwise take advatage of the feature that’s been staring them in the face for decades. The personal investment of time and scarcity of instructional material made it very apparent this isn’t something just anyone can get up and running. Pretty quickly it became clear why it never took off in the consumer space. For the past few years I’ve been studying it in my free time. The idea of booting from a network resource, it always fascinated me.
