===Setup PXE Booting===
 +
 
 +
Some rough notes on setting up PXE booting for linux using syslinux
 +
 
 +
https://wiki.syslinux.org/wiki/index.php?title=PXELINUX
 +
 
 +
To use a menu we need a copy of pxelinux.0
 +
 
 +
From the syslinux wiki link above:
 +
 
 +
On the TFTP server, create the directory "/tftpboot", and copy "pxelinux.0" (from the Syslinux distribution) and any kernel or initrd images that you want to boot.
 +
[5.00+] Also copy "ldlinux.c32" from the Syslinux distribution to the "/tftpboot" directory on the TFTP server.
 +
Finally, create the directory "/tftpboot/pxelinux.cfg". The configuration file (equivalent of syslinux.cfg -- see the SYSLINUX FAQ for the options here) will live in this directory.
 +
 
 +
The actual linux image and any associated files need to be extracted from a source distribution ISO here:
 +
 
 +
/tftpboot/images/{name_of_distro}
 +
 
 +
 
 +
====Menus====
 +
 
 +
We can create a menu system with sub menus as well.
 +
 
 +
Yu will need this from the syslinux ISO:
 +
 
 +
/tftpboot/com32/vesamenu.c32
 +
 
 +
You can add a background image like this:
 +
 
 +
/tftpboot/images/graphics/background.png
 +
 
 +

Example /tftpboot/pxelinux.cfg/default:

===Voip Phones===
 +
 
 +
You can use tftpd with your Voip phones.
 +
 
 +
More advanced phones will allow you to choose a directory for your firmware where. More basic phones may not be able to you anything other than the default root directory.
 +
 
 +
e.g
 +
I have some old Mitel phones use /tftpboot only
 +
I have a number of new Grandstream phones that can load from /tftpboot/some_directory
 +
 
 +
Most Voip phone scan read a config file based on their MAC address to configure themselves during boot.
 +
This can take a while to set up but is a massive time saver.

smeserver-tftp-server

Maintainer: Trevor Batley

Contrib 10:
Contrib 9:
smeserver-tftp-server
The latest version of smeserver-tftp-server is available in the SME repository, click on the version number(s) for more information.


Description

This contribution adds a tftp server (tftp-server) to your smeserver (primarily used by workstations that are using the pxeboot protocol to retrieve boot images and parameters from the server).

It was produced to support my smeserver-thinclient contrib, but can be used independently.

Requires

  • smeserver >= 10.0
  • tftp-server >= 0.49

For a lot of linux distros you will need nfs support

https://wiki.koozali.org/NFS

You will a /etc/exports line similar to this: 

/tftpboot/ *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

mkdir -p /etc/e-smith/templates-custom/etc/exports/
echo "/tftpboot/ *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)" > /etc/e-smith/templates-custom/etc/exports/30tftp
expand-template /etc/exports

/tftpboot/images/ubunturescue_1104/ *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

if you have installed smeserver-nfs

Installation

This contrib is held in the smecontribs repository, so the following commands will install on your smeserver. 

yum --enablerepo=smecontribs install smeserver-tftp-server

Note: this will download and install the latest tftp-server from the Centos base repository, so if you don't have that repository ebnabled, please use the following command 

yum --enablerepo=smecontribs --enablerepo=base install smeserver-tftp-server

The tftp status can be controlled via the Thin Clients server-manager panel if you have installed my smeserver-thinclient contrib.

If you haven't, you'll need to enable the tftp server manually from the shell (logged in as root) 

config setprop tftp status enabled
signal-event smeserver-tftp-server-update

If for any reason the tftp server isn't running, try: 

systemctl restart tftp

Defaults

You shouldn't need to play with any parameters (except status). The defaults and allowed values are listed below.

<prop> default <value> allowed Values description
status disabled enabled/disabled
access private private/public/localhost
log normal normal/verbose/disabled equivalent to -v or -vv or none
user nobody nobody/<user> default to nobody, any valid user id
privilege ro ro/rw read-only or read-write (rw equivalent to -c)
timeout default default/nnn timeout value in seconds (default is 900)
directory /tftpboot any directory
blksize 1 Value between 512-65464 e.g. equivalent to -B [512-65464]
refuse 2 any tftp parameter e.g. blksize equivalent to -r blksize

These settings can be set/changed via 

config setprop tftp <prop> <value>
signal-event smeserver-tftp-server-update

*1 blksize does not have a default entry in the configuration database. It can be added as above or removed via

see Bug 10646 for updated tftp contrib with addition of default setting 

config delprop tftp blksize
signal-event smeserver-tftp-server-update

*2 refuse does not have a default entry in the configuration database. It can be added as above or removed via 

config delprop tftp refuse
signal-event smeserver-tftp-server-update

Setup PXE Booting

Some rough notes on setting up PXE booting for linux using syslinux

https://wiki.syslinux.org/wiki/index.php?title=PXELINUX

To use a menu we need a copy of pxelinux.0

From the syslinux wiki link above:

On the TFTP server, create the directory "/tftpboot", and copy "pxelinux.0" (from the Syslinux distribution) and any kernel or initrd images that you want to boot. [5.00+] Also copy "ldlinux.c32" from the Syslinux distribution to the "/tftpboot" directory on the TFTP server. Finally, create the directory "/tftpboot/pxelinux.cfg". The configuration file (equivalent of syslinux.cfg -- see the SYSLINUX FAQ for the options here) will live in this directory.

The actual linux image and any associated files need to be extracted from a source distribution ISO here:

/tftpboot/images/{name_of_distro}


Menus

We can create a menu system with sub menus as well.

Yu will need this from the syslinux ISO:

/tftpboot/com32/vesamenu.c32

You can add a background image like this:

/tftpboot/images/graphics/background.png


Example /tftpboot/pxelinux.cfg/default: 

menu title --== SME Linux, PXE Main Menu ==--
menu background graphics/background.png

We then need to create separate sub menu configuration files in the same directory. Note the use of NFS is required for some of the setups here.

These are old configs that have not been tested recently but should give an idea. Please update with any recent information

Voip Phones

You can use tftpd with your Voip phones.

More advanced phones will allow you to choose a directory for your firmware where. More basic phones may not be able to you anything other than the default root directory.

e.g I have some old Mitel phones use /tftpboot only I have a number of new Grandstream phones that can load from /tftpboot/some_directory

Most Voip phone scan read a config file based on their MAC address to configure themselves during boot. This can take a while to set up but is a massive time saver.
