PXE NOTLARI
===========
Bu kurulumda `dnsmasq`, proxy DHCP olarak kullanılmıştır. Yani ortamda bir DHCP
sunucu var, `dnsmasq` sadece TFTP yönlendirmesini yapıyor. TFTP sunucu, yine
`dnsmasq`...

## Kurulum
```
apt-get install dnsmasq
apt-get install pxelinux syslinux syslinux-common syslinux-utils
```

## /etc/dnsmasq.d/pxe
```
bind-interfaces
interface=eth0
port=0

dhcp-range=192.168.1.0,proxy
dhcp-boot=pxelinux.0
dhcp-no-override

enable-tftp
tftp-root=/var/lib/tftp
pxe-service=x86PC,'myTFP',pxelinux

log-dhcp
```

## TFTP
```
mkdir -p /var/lib/tftp/pxelinux.cfg
cd /var/lib/tftp/
cp /usr/lib/PXELINUX/pxelinux.0 .
cp /usr/lib/syslinux/modules/bios/{ldlinux,libmenu,libutil,menu}.c32 .
```

## Kernel ve initrd
```
mkdir -p /var/lib/tftp/stretch
cd /var/lib/tftp/stretch

wget -O /tmp/netboot.tar.gz \
    http://ftp.nl.debian.org/debian/dists/stretch/main/installer-amd64/current/images/netboot/netboot.tar.gz
tar zxf /tmp/netboot.tar.gz -C /tmp
cp /tmp/debian-installer/amd64/{initrd.gz,linux,bootnetx64.efi} .
```

## /var/lib/tftp/pxelinux.cfg/default
```
