Tftp server
smeserver-tftp-server
Maintainer: Trevor Batley
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 >= 7.0
- tftp-server >= 0.39
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
Officially you should then need to apply the database changes etc. Whilst this is not required to be able to run the tftp server straight away, it will be required at some stage, and the server manager will remind you to, until you do.
signal-event post-upgrade signal-event reboot
The tftpd status is 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
config setprop tftpd status enabled signal-event tftpd-conf
If for any reason the tftp server isn't running, try:
service tftpd restart
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 tftpd <prop> <value> signal-event tftpd-conf
*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 tftpd blksize signal-event tftpd-conf
*2 refuse does not have a default entry in the configuration database. It can be added as above or removed via
config delprop tftpd refuse signal-event tftpd-conf
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 menu tabmsgrow 22 menu cmdlinerow 22 menu endrow 24 menu color title 1;34;49 #eea0a0ff #cc333355 std menu color sel 7;37;40 #ff000000 #bb9999aa all menu color border 30;44 #ffffffff #00000000 std menu color pwdheader 31;47 #eeff1010 #20ffffff std menu color hotkey 35;40 #90ffff00 #00000000 std menu color hotsel 35;40 #90000000 #bb9999aa all menu color timeout_msg 35;40 #90ffffff #00000000 none menu color timeout 31;47 #eeff1010 #00000000 none prompt 0 noescape 1 allowoptions 0 timeout 0 default com32/vesamenu.c32 label linuxmenu menu label ^Linux Boot Disks Menu kernel com32/vesamenu.c32 append pxelinux.cfg/linux_boot_disks label Arch menu label ^Arch Boot Disks Menu kernel com32/vesamenu.c32 append pxelinux.cfg/arch label bootimg menu label ^Other Boot Images kernel com32/vesamenu.c32 append pxelinux.cfg/bootimg
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.
Sample for /tftpboot/pxelinux.cfg/linux_boot_disks
The symbol ^ as per eg "Back to ^Main" is used to create an underlined shortcut key M in this instance.

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 takea while to set up but is a massive time saver.

This can aid with basic tftpd setup.
There is also a distro called Thinstation This PXE it's own Linux distro that can be used a thin client.
Uninstall
yum remove smeserver-tftp-server tftp-server signal-event post-upgrade ; signal-event reboot
If you want to fully clean up, by removing the entries from the configuration database
config delete tftpd
