=TFTP configuration=

TFTP can manage different configurations, up to 1 per host! 

This is how a ThinClient (= netBoot client) will retrieve its configuration:


[[File:TFTP getConfiguration().png|none|TFTP getConfiguration()]]


As you can see you have 3 possibilities:


1. '''MAC @ filter'''. Configuration file name must be:
* Start with ARP type '01-'
* all in lower case hexadecimal
* dash '-' separators instead of ';' 
for example a MAC @ 88:99:AA:BB:CC:DD would search for the filename 01-88-99-aa-bb-cc-dd.


2. '''IP @ filter'''. Configuration file name must be:
* host IP / network address in hexadecimal
* all in upper case
e.g. 192.0.2.91 -> C000025B 


3. '''Default configuration'''

=TFTP folder tree=

This is how we'll setup our files and folders:

<syntaxhighlight lang="bash">
##### TFTP root
/tftpboot/                                   


#### PXE application
/tftpboot/pxelinux.0


#### Boot configuration

/tftpboot/pxelinux.cfg/                # PXE configuration(s)
/tftpboot/pxelinux.cfg/menu.c32        # PXE interactive menu (text)
/tftpboot/pxelinux.cfg/vesamenu.c32    # PXE interactive menu (graphical)

/tftpboot/pxelinux.cfg/default                  # default NetBoot configuration

/tftpboot/pxelinux.cfg/01-ec-a8-6b-fd-da-44     # specific configuration for host with MAC @ "EC-A8-6B-FD-DA-44"


#### Netboot Kernels

/tftpboot/images/
