== 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.

=== DHCP Configuration =How do I find my IP Address? ====

If you would like 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 obtain an ip address dynamically via DHCPthe Raspberry Pi. Additionally, leave the "headless" file emptyIP Address will be flashed through the LED on the Raspberry Pi soon after the IP Address is read through the speakers.

If you would like to specify a specific [https://github.com/ctyler/ip-info/blob/master/README.md For more information about IP address you will need to include the Address reading and IP Addressflashing, Netmask and Gateway, place the following information in the "headless" file:click here]

=== Sample headless file Static Configuration ===

IPADDR=192If 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).168.1.105 NETMASK=255.255.255.0 GATEWAY=192.168.1.1

== Headless Mode is enable with DHCP -- How do I find out my ip-address? ==Required Configuration====

After you have enabled headless mode with either the DHCP configuration or Static IPADDR=[IP configuration, the ip address that has been assigned to Address of 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] NETMASK=[Mask to define network subnet] GATEWAY=[IP Address of router/ACT LED.gateway]

This means that if you are not planning on using X while in Headless Mode, you should switch to Run Level 3 to save memory.
