MAC Based booting
Installing with PXE and FAI MAC Address based.
With this hooks and some small changes in dhcpd.conf (based on FAI-CD) every computer that boots fai gets a MAC based config file installed in the pxelinux.cfg/ dir. May be in the future a GUI can use/change this information.
File dhcpd.conf
....
# deny unknown-clients
....
subnet 192.168.1.0 netmask 255.255.255.0
{
range 192.168.1.200 192.168.1.249;
....
If you press <shift> key during pxe booting you can get a prompt.
Possible commands are:
mkboot HOST=local mkboot HOST=remove ..... mkboot HOST=demohost .....
Hook mkboot
#! /bin/bash
# hook mkboot for fai.
# If you start this script on a fai client it copy, create or delete a pxe bootfile. It use the ethernet mac
# address of the fai client.

if [ "$HOST" != "" ]; then HOSTNAME=$HOST; fi ;
BOOTMAC=`/sbin/ifconfig "$netdevices_up" |grep HWaddr|cut -d " " -f11|tr ':' '-'|tr '[:upper:]' '[:lower:]'`
BOOTMAC="01-"$BOOTMAC
echo Next Boot will boot or install: $HOSTNAME on $BOOTMAC.
