{{Pidora}}[[Category:Pidora 18 (Raspberry Pi Fedora Remix)]]
{{Admon/important | Notice |Headless mode = What is currently a experimental feature, updates to headless mode and current issues can be found below}}? =
== What is {{Admon/important| Security Warning! | If you are going to use headless mode? ==it is critical that you change the root password as soon as possible, because Pidora is set with a default root password that is publicized.}}
Headless mode is a system configuration which enables access to a raspberry pi, through ssh on a network, without the use of a monitor or keyboard plugged into the raspberry pi. This mode does require another computer to ssh into the raspberry pi. When this feature is enabled, [[Pidora 18 Firstboot|firstboot]] is bypassed 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.
Flash IP Example:1-9 flashes = 1-9 digit in IP Address10 flashes = 0 digit in IP Addressshort delay = next digit in iplong delay = . in IP Address {{Admon/important| Security Warning! | If you are going to use headless mode it is critical that you change the root password as soon as possible, because Pidora is set with a default root password that is publicized.}} == Enabling Headless Mode on Pidora ==
To enable Headless Mode, create a file named "headless" inside the boot file system on the Raspberry Pi's SD card. Create this "headless" file before you 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:''' 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==
{{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] ====How do I find my IP Address? ==== 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 connected to the Raspberry Pi. Additionally, the IP Address will be flashed through the LED on the Raspberry 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 [https://github.com/ctyler/ip-info/blob/master/README.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 your Raspberry Pi, you will need to modify the "headless" file, adding an IP Address, Gateway, and Netmask, to the file for the configurations to work properly(see samples configs below).
'''Static ====Required Configuration:'''Required parameters for a Headless Mode static configuration.====
IPADDR=[IP Address of Raspberry Pi] NETMASK=[Mask to define network subnet] GATEWAY=[IP Address of router/gateway]
'''====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]
=== Sample Headless Mode Static Configuration ==Configurations =
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
SWAP=512
== Headless Mode is enable ==Dynamic Configuration(with DHCP -- How do I find out my ip-address? rootfs resizing and swap creation)==== RESIZE SWAP=512 = SSH to The Headless Pi =
After you have enabled headless mode with either the DHCP configuration or Static IP configuration, the ip address that has been assigned to Raspberry Pi will be played through the speakers '''2 minutes''' after you have powered the Raspberry Pi, and '''30 seconds''' later it will also flash your ip address through Pi's OK/ACT LED. Default User: root Default Password: raspberrypi ssh root@{ip_address}

== Headless Mode Script Update ==Two IP Addresses====Initially there were a few issues with dchp and headless mode since our release the headless script has been updated. It has not been officially added When switching in between Headless Mode Configuration states, static ip to dynamic ip, or dynamic ip to static ip, both IP Addresses from each configuration will be active for the updates repo yet butsingle boot, 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 /usr/bin/headonuntil a reboot takes place.

== SSH to the headless Pi ==[https://fedoraproject.org/wiki/Systemd#How_do_I_change_the_target_.28runlevel.29_.3F For more information about changing Run Levels on Pidora, click here.]
ssh root@{ip_address}====Slower Boot====Default user: root/raspberrypiWhen running headless mode, the speed of the boot is slowed down, this is due to a network change during boot.
