Network boot

From Transwiki

Jump to: navigation, search

gPXE is a Preboot EXecution Environment (PXE) and bootloader. Enables computers without built-in PXE BIOS support to boot from the network, and supports extra protocols beyond TFTP to transfer boot data, including HTTP, iSCSI and ATA over Ethernet (AoE), and even Wi-Fi.

Using gPXE by default allows a portable boot where one can boot via the Internet, but The size of most boot images would make this slow enough that sticking with atftpd sounds like a good idea.

[edit] Packages to install on server

  • No need to install pxe!
  • tftp-hpa - advanced trivial ftp deamon - which includes logging
  • syslinux-common

[edit] Make a gPXE Thumbdrive

Go to rom-o-matic Chose a "USB keychain" image.

Plug in some usb thumbdrive - if it automounts - unmount it

tail /var/log/syslog 

Note the /dev/sgx where x varies and do a dd copy

# dd if=/path/to/gpxe-1.0.1-gpxe.usb of=/dev/sgx
# sync

Wait to make sure the led stops flashing - you now have a pxe boot.

On the server you will want to copy memdisk, vesamenu.c32, pxelinux.0 from /usr/lib/syslinux/ and place in /srv/tftp/

# mkdir /svr/tftp/pxelinux.cfg

After populating the appropriate directories, make a file called default in /svr/tftp/pxelinux.cfg with content similar to :

default vesamenu.c32
