I don't have any specific documentation and my setup might be limited to my
environment, but just thought I'd share what I have. I've got the next server
and filename parameters specified in a client class and then add that to
certain pools:
{
"Dhcp4": {
...
"client-classes": [
{
"name": "pxe_bios_x86",
"test": "substring(option[60].hex,0,9) == 'PXEClient' and option[93].hex ==
0x0000",
"next-server": "10.2.84.194",
"boot-file-name": "/pxeboot/pxelinux.0"
}
]
"subnet4": [
{
"id": 12
"subnet": "10.2.24.0/22"
...
"pools": [
...
{
"pool": "10.2.27.65 - 10.2.27.96"
"client-class": "pxe_bios_x86"
}
]
}
]
}
}
On my tftp server I use tftpd-hpa:
user@ftphost:~$ cat /etc/default/tftpd-hpa
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/srv/tftp"
TFTP_ADDRESS="10.2.84.194:69"
TFTP_OPTIONS="--listen --secure --port-range 58000:58999 -vvv"
And under my pxeboot directory I have my PXE configuration:
user@ftphost:~$ ls -l /srv/tftp/pxeboot/
total 79376

The main menu takes you to various other sub-menus (i.e. Linux -> Ubuntu -> "Various
Ubuntu distro options", etc) which are defined in their own files. Also this only works
for BIOS (CSM) systems on x86 over IPv4. I've yet to configure UEFI for IPv4 or anything for
IPv6.

Where can I find documentation on setting up pxebooting to do linux installs? I'm
running kea-1.8.0-2 on Rocky Linux 8.5. I want to be able to pxeboot different OS's like
centos 7.x, rocky 8.x and future releases. The tftp-server is installed and setup,
syslinux packages are installed. I've got just a couple clients defined in dhcp as
reserved leases and added next-server and filename options for one but when I boot the
network from that client it never seems to get to the pxelinux.0 or the defined kernel in
the "pxelinux.cfg/01-macaddress" file.
I figure I'm probably missing some setup in the kea-dhcp4.conf file but can't
find what the missing parts might be.
My old setup is centos 6, dhcp-4.1.1. I'd add the next-server and filename
lines for a particular host reservation then use pxeboot to setup the
pxelinux.cfg file and that would have kernel parameters to boot the installer
and read a kickstart file. Right now I can get the new system to boot from the
network, it gets an IP from kea but then fails to find the tftp file to boot
from.
Additional related issue: On my previous dhcpd setup I'd setup a new system to boot
and install from the network with the pxeboot command and it would create the
pxelinux.cfg/<host identifier> file with the kernel that's available from tftp
and an append line. I can't find the pxeboot command anywhere in Rocky Linux 8.x. I
can hand jam those files if needed but was curious if the utility is available
somewhere. There's a pxeos.xml file in that setup and it's also seemingly not
available in RL8 or kea.
