We are not using a PXE server to achieve this as it is not +mandatory. +You can install tftp-server and dhcp-server package from the Mandrake +distribution for example. + +On the server machine at 192.168.2.1, you will find a "/etc/dhcpd.conf" sample +file written by Florin Grad <florin@mandrakesoft.com>, where "mydomain.com" is +assumed to be your domain name, and 192.168.1.1 a name server. All install are +done on subnet 192.168.2.0. + +All the files that will be downloaded by the tftp daemon are located under +"/tftpboot" : + "/tftpboot/pxelinux.0" is a program that is loaded directly by the machine + where a network boot will be done, this program comes + from the SYSLINUX package by H. Peter Anvin. (look at + http://syslinux.zytor.com/pxe.php for more information) + "/tftpboot/pxelinux.cfg/" is a directory where all configuration file for + pxelinux.0 will be found, pxelinux.0 will download + these file by itself. It searches first for a file + named accordind to the machine IP address in + hexadecimal, for example for 192.168.2.20, it + looks for "C0A80214" first, then "C0A8021" and so + on down to "C0", "C" and "default". + "/tftpboot/network.rdz" is the standard network initrd for Mandrake installation. + "/tftpboot/vmlinuz" is the boot kernel for installation. + "/tftpboot/help.msg" is the message displayed by pxelinux.0, note that currently + graphical message (as for install using SYSLINUX 1.48 with + graphic patch by Mandrake) is not supported. + +All file "network.rdz", "vmlinuz", "help.msg" can be found by mounting "network.img", +or the network floppy disk used for install, "pxelinux.cfg" is just an adaptation +of the file found on the "network.img" called "syslinux.cfg" but without the reference +to boot.msg (as it is not currently supported). + +Update network configuration for your needs and start dhcp server on the machine and +tftp server and this should work. + +******************************************************************************** +* /etc/dhcpd.conf ************************************************************** +******************************************************************************** +ddns-update-style ad-hoc; + +authoritative; + +option space PXE; +option PXE.mtftp-ip code 1 = ip-address; +option PXE.mtftp-cport code 2 = unsigned integer 16; +option PXE.mtftp-sport code 3 = unsigned integer 16; +option PXE.mtftp-tmout code 4 = unsigned integer 8; +option PXE.mtftp-delay code 5 = unsigned integer 8; +option PXE.discovery-control code 6 = unsigned integer 8; +option PXE.discovery-mcast-addr code 7 = ip-address; + +default-lease-time 28800; +max-lease-time 86400; + +option domain-name "mydomain.com"; +option domain-name-servers 192.168.1.1; + +class "PXE" { + match if substring(option vendor-class-identifier, 0, 9) = "PXEClient"; + option vendor-class-identifier "PXEClient"; + + vendor-option-space PXE; + option PXE.mtftp-ip 0.0.0.0; + next-server 192.168.2.1; #tftp server location + + filename "pxelinux.0"; # standard TFTP + +} + +shared-network "mynetwork" { + subnet 192.168.2.0 netmask 255.255.255.0 { + option subnet-mask 255.255.255.0; + option routers 192.168.2.1; + + ddns-domainname = "mydomain.com"; + + pool { + range 192.168.2.10 192.168.2.20; + allow members of "PXE"; + } + } +} +******************************************************************************** +* /tftpboot/pxelinux.cfg/default *********************************************** +******************************************************************************** +default linux +prompt 1 +timeout 72 +display help.msg +label linux + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 vga=788 +label vgalo + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 vga=785 +label vgahi + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 vga=791 +label vga16 + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 vga16 +label text + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 text +label patch + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 patch vga=788 +label expert + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 expert vga=788 +label rescue + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 rescue rw +label lnx4win + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz root=/dev/ram3 lnx4win vga=788 +label preinst + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz automatic=method:cdrom root=/dev/ram3 rescue oem rw +label oem + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz automatic=method:cdrom root=/dev/ram3 rescue oem rw +label auto + kernel vmlinuz + append ramdisk_size=32000 initrd=network.rdz auto_install=Mandrake/base/auto_inst.cfg.pl +******************************************************************************** +* Usefull linkst *************************************************************** +******************************************************************************** + +http://syslinux.zytor.com/pxe.php +http://www.kano.org.uk/projects/pxe/ |
