show_all_variables.ipxe
=================

Description: will show all (or most) variables (List: http://ipxe.org/cfg) currently assigned or inherited by the dhcp server, perfect when testing, saved me a bunch of time... It is formatted to fill exactly the full page, and show the dhcp option id when it exists.

Code:

#!ipxe

# Made by ZeroQI

# PXE error codes        http://h18013.www1.hp.com/products/servers/management/rdp/knowledgebase/00000138.html

# Ascii to Hec convertor http://easycalculation.com/ascii-hex.php

#In the same way that option 43 is an option space containing vendor-encapsulated options,

# gPXE/iPXE uses option 175 to contain gPXE-specific encapsulated options.

You are aware of the "config" command, aren't you? Any reason why you'd go to all this trouble when it is there? It is designed for interactive use. http://ipxe.org/cmd/config

I was aware of config command but it didn't show when i tried the values of "no-pxedhcp" and "use-cached", and other variables. I simply wanted to show all variables and also the corresponding dhcp option and how to display/use it in a script in an easy way... I do believe this script achieve that.

============
Here is a small test showing me how long it takes in seconds to transfer files of different sizes, to compare FTP, TFTP, and HTTP performance...

Code:

#!ipxe

=======
Before menu command i made a small menu that would be called, allowing me to load either PXElinux 3.86 or PXElinux 4.04 with the same menu, so it is easy to carry out tests...

Might be useful for people using older versions of iPxe

Code:

:menu

echo iPXE menu

echo =========

echo 1) Show_all_variables.ipxe

echo 2) Speed_test.ipxe

echo ===============================================

echo 3) iPXE -> Vesamenu.c32 [no pxelinux, exit when runnin script]

echo 4) TFTP Chainload PXElinux 3.86 [Com32]

echo 5) TFTP Chainload PXElinux 4.04 [Com32R]

echo

echo 6) iSCSI Boot iso (int 0x13 or iSCSI driver managed)

echo 7) http sanbooot (Currently fails with)

echo 8) memdisk http load

echo

echo 9) Reboot (if compiled in kernel)

echo 0) Exit to iPXE shell prompt

echo

echo -n Please select the option: 

read key

goto option_${key} || goto menu # loop back if empty or wrong

#iseq option_${key} option_ && goto menu || #loop back if empty choice only

echo "goto" support not implemented option for key "${key}" doesn't exist

Here is the iSCSI code i wrote when using starwind software iSCSI solution...

I thought it could help somebody doing the same...

Code:

#!ipxe

 :unknown

 echo Unknown host ${hostname}

#!ipxe

#to enable when embedded, use cache set to 1 if kkpxe, not for kpxe due to dropped pxe stack
