-====== Installing the PXE Server====== 
  
-This tutorial was done with a Debian 8. And it will only be possible to automaticly boot an OS according to the modules MAC adress. In this configuration there is no GUI to select a boot image. 
- 
-All operation where donw with root permissions. 
- 
-First the fowlloing services have to be installed: 
-<code> 
-apt-get install dnsmasq, nfs-kernel-server 
-</code> 
-''dnsmasq'' serves as DHCP Server to tell teh clients what IP adress to use and which kernel they have to load. 
-Also it runs the TFTP Server that provides the kernel images. 
- 
-''nfs-kernel-server'' provides the nfs network share for the rootfs and a persistent storage. 
- 
-=====Setting up dnsmasq===== 
- 
-the config file can be opende with 
-<code> 
-nano /etc/dnsmasq.conf 
-</code> 
- 
-All DHCP Options used in the following config can be found here [[http://www.networksorcery.com/enp/protocol/bootp/options.htm|Link]] 
-The following shows an example configuration for 3 drifferent mdoules and 4 different kernel. 
-<file INI> 
-#Binds the DHCP server to eth0 
-interface=eth0 
-#Sets the IP range with a lease time of 8 hours 
-dhcp-range=192.168.13.201,192.168.13.249,255.255.255.0,8h 
- 
-#Enables the TFTP service of dnsmasq 
-enable-tftp 
-#Bind the TFTP root folder  to the set folder 
-tftp-root=/srv/tftpboot/ 
-#DHCP Option 66 sets which TFTP Server will be used by the client 
-dhcp-option=66,192.168.13.80 
-#DHCP Option 42 sets a NTP time server 
-dhcp-option=42,130.133.1.10 
- 
- 
-#The following sets a flag for all MAC adresses starting with the given number, 
-#so it is possible to set different setups for different modules 
-dhcp-host=00:14:2d:*:*:*,set:toradexApalis  
-dhcp-host=00:0e:c6:*:*:*,set:toradexColibriAndroid 
-#"set:christmannExynosLinux" has to be changed to "set:christmannExynosAndroid" in order to load 
-#the Android kernel 
-dhcp-host=70:b3:d5:56:*:*,set:christmannExynosLinux 
- 
- 
-#These different tags can be used with "tag:"tagname","option"" 
-#"dhcp-boot" defines which kernel will be loaded from the TFTP root path 
-#"dhcp-option" gives an option to the set MAC adress group 
- 
-#Kernel filename for Toradex Apalis T30 provided by the TFTP Server 
-dhcp-boot=tag:toradexApalis,toradexApalis_uImage 
-#Root path that is shared by the nfs-kernel-server 
-dhcp-option=tag:toradexApalis,17,/srv/nfs/apalisT30/rootfs/ 
- 
-#Kernel filename for Toradex Colibri T20 
-dhcp-boot=tag:toradexColibri,toradexColibri_uImage 
-#Root path 
-dhcp-option=tag:toradexColibri,17,/srv/nfs/colibriT20/linux/rootfs/ 
- 
-#Kernel filename for Christmann Apalis Exynos Linux 
-dhcp-boot=tag:christmannExynosLinux,uImage-ExynosLinux 
-#Root path 
-dhcp-option=tag:christmannExynosLinux,17,/srv/nfs/apalisExynos/linux/rootfs/ 
- 
-#Kernel filename for Christmann Apalis Exynos Android 
-dhcp-boot=tag:christmannExynosAndroid,uImage-ExynosAndroid 
-#Root path 
-dhcp-option=tag:christmannExynosAndroid,17,/srv/nfs/apalisExynos/android/rootfs 
-</file> 
- 
-After the ''dnsmasq.conf'' has been changed the dnsmasq service has to be restarted in order to apply the changes using: 
-<code> 
-/etc/init.d/dnsmasq restart 
-</code> 
-
