== What is headless mode? ==
Headless {{Admon/important| Security Warning! | If you are going to use headless mode it is a system configuration in which critical that you change the display deviceroot password as soon as possible, keyboard, or mouse because Pidora is lacking. When this feature is enabled, [[Pidora 18 Firstboot|firstboot]] set with a default root password that is bypassedpublicized.}}
{{Admon/important| Security Warning! | If you are going Headless mode is a system configuration which enables access to a raspberry pi, through ssh on a network, without the use headless of a monitor or keyboard plugged into the raspberry pi. This mode it does require another computer to ssh into the raspberry pi. When this feature is critical that you change the root password as soon as possibleenabled, because [[Pidora 18 Firstboot|firstboot]] is set with a default root password that is publicizedbypassed and disabled. Additionally, Headless Mode will enable services to read your IP Address through plugged in speakers or headphones. It will also flash the IP Address to you on the Raspberry Pi LEDs.}}
== Enabling headless mode Headless Mode on Pidora ==
To enable headless modeHeadless Mode, you will need to create a file named "headless" in inside the boot filesystem file system on your the Raspberry Pi's SD card ''. Create this "headless" file before'' you insert the card into boot your Raspberry Pi.
'''== Enable Headless Mode On Linux''':==
Tutorial Video: http://youtu.be/ALUAmw6Mz_o
Insert the SD card into your system, and create a file named "headless" in the filesystem labelled "boot".
'''== Enable Headless Mode On Windows=={{Admon/important| Note | If you are using a Windows OS you will need to remove the .txt file extension on the headless file.[http://www.ehow.com/how_6394953_create-file-extension.html More information on removing file extensions on eHow]}}Insert the SD card into your system. Only the boot filesystem will be made available, because Windows will not be able to read other partitions on the card. Create a file named "headless" on that partition There are two possible configurations for Headless Mode "DHCP" configuration and "Static" configuration. == DHCP Configuration == If you would like to configure the Raspberry Pi to use DHCP, ''leave the "headless" file empty'', and the Raspberry Pi should be assigned an IP Address dynamically. ====Optional Configuration====If "RESIZE" is in the "headless" file, the root filesystem will be expanded to the maximum size of the sd card via the service rootfs-resize. If "SWAP"(requires the value in megabytes) exists in the "headless" file, a swap file will be created of the specified size, and then activated.  RESIZE SWAP=[Size of swap in megabytes]

{{Admon/important| Note | If you Once Headless Mode has been Enabled, and the Raspberry Pi has finished booting, the IP Address of the Raspberry Pi will be read out through the speakers or headphones that are using a Windows OS you will need connected to remove the Raspberry Pi.txt file extension Additionally, the IP Address will be flashed through the LED on the headless fileRaspberry Pi soon after the IP Address is read through the speakers.  1 - 9 short flashes indicate the digits 1 - 9 10 short flashes indicate the digit 0 a long flash indicates an octet separator (dot) a brief pause separates digits [httphttps://www.ehowgithub.com/how_6394953_createctyler/ip-file-extensioninfo/blob/master/README.html More md For more information about IP Address reading and IP Address flashing, click here] == Static Configuration == If you would like to set a static, non-changing, IP Address on removing your Raspberry Pi, you will need to modify the "headless" file extensions on eHow]}}, adding an IP Address, Gateway, and Netmask, to the file for the configurations to work properly(see samples configs below).
There are two possible configurations for headless-mode "DHCP" configuration and "Static" configuration.====Required Configuration====
IPADDR=[IP Address of Raspberry Pi] NETMASK=[Mask to define network subnet] GATEWAY= DHCP Configuration ===[IP Address of router/gateway]
====Optional Configuration====If you would like "RESIZE" is in the "headless" file, the root filesystem will be expanded to obtain an ip address dynamically the maximum size of the sd card via DHCP, leave the service rootfs-resize. If "SWAP"(requires the value in megabytes) exists in the "headless" file empty, a swap file will be created of the specified size, and then activated.
RESIZE SWAP=== Static Configuration ===[Size of swap in megabytes]
If you would like to specify a specific IP address you will need to include the IP Address, Netmask and Gateway, place the following information in the "headless" file:= Sample Headless Mode Configurations =
=== Sample headless file Static Configuration ===Below are sample configurations, they may require you to enter valid ip information specific to the network you are running it on.
====Static Configuration(without rootfs resizing or swap creation)====
IPADDR=192.168.1.105
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
== ==Static Configuration(with rootfs resizing and swap creation)==== IPADDR=192.168.1.105 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 RESIZE SWAP=512 ====Dynamic Configuration(with rootfs resizing and swap creation)==== RESIZE SWAP=512 = SSH to The Headless Mode is enable with DHCP -- How do I find out my ip-address?

After you have enabled headless mode with either the DHCP configuration or Static ====Two IP configurationAddresses====When switching in between Headless Mode Configuration states, static ip to dynamic ip, the or dynamic ip address that has been assigned to Raspberry Pi static ip, both IP Addresses from each configuration will be played through the speakers '''2 minutes''' after you have powered active for the Raspberry Pisingle boot, and '''30 seconds''' later it will also flash your ip address through Pi's OK/ACT LEDuntil a reboot takes place.
[https://github====Graphical Mode Not Disabled====Headless Mode does not disable X, and can run in both Run Level 3 or 5.com/ctyler/ip-info/blob/master/READMEThis means that if you are not planning on using X while in Headless Mode, you should switch to Run Level 3 to save memory.md More information about ip-read and ip-flash]
== Headless Mode Script Update ==Initially there were a few issues with dchp and headless mode since our release the headless script has been updated[https://fedoraproject. It has not been officially added to the updates repo yet but, if you are interested in trying this mode out now you can copy and replace the old headon script with the updated one located at org/usrwiki/bin/headonSystemd#How_do_I_change_the_target_.28runlevel.29_.3F For more information about changing Run Levels on Pidora, click here.]
