#BOOT IT Insert the SD card into the Raspberry Pi and use the serial console from the USB to TTL while plugged in to your LINUX system. Once we close up our Pi, we can both power and access it via the USB end of the USB to TTL cable. (ls -al /tmp/root/boot cp /tmp/root/boot/* /tmp/boot rm -rf /tmp/root/boot/* ls -al /tmp/root/boot) #ONELINE #You will need to be SUPER USER(root) to do this. #ONE LINE FORMAT OF SD CARD (Careful, make sure this is the right device)Įcho -e "p\no\np\nn\np\n1\n\n+100M\nt\nc\np\nn\np\n2\n\n\np\nw" | fdisk /dev/mmcblk0 #ONELINE Put the SD card in your Linux system sorry, no instructions for Windows systems at this time. Optional: -External Smart Phone Battery Pack/Charger Micro USB Wifi Adapter (Careful, not all adapters work with every Pi operating system sometimes you need drivers) SD Card (Careful, not all SD cards, “or revisions of prior working cards”, are Pi compatible.) USB to Serial Cable (Careful, some of these can have counterfeit chip sets and may not work correctly) USB to TTL Cable (Careful, some of these can have counterfeit chip sets and may not work correctly) so, you can use an (optional) battery pack or a powered USB port from any device or server to run a Pi. Yes indeed, the Pi can be powered from just about any powered USB source. The following steps will show how to setup “ARCH Linux” as a (Headless) “Pocket Serial Console Server” that can be used to access "Legacy Systems" anywhere in the Data Center. We will use a USB to TTL cable to both power and access the Pi as a headless Linux computer. Not only is it a neat toy but it may, in fact, fill a need you did not know you had. If you find that you need to get give yourself or someone else (out of band) remote access to a "Legacy System" that has no modern “Network Management” capabilities consider using a Raspberry Pi. in fact, this is in the case with Legacy UNIX systems the "Serial Console" is likely the only way to access or operate them in an emergency. Such systems likely have no "Network Management" or Graphics cards. as no one gets many calls about them they are out of sight and out of mind. These systems steadily hum along in the dark and dusty remote reaches of Data Centers HAUNTING operations staff because no one truly knows the current status or utilization of such systems and even less is known about who set them up or how to support them in the event of a failure. Where Inevitably "Legacy Systems" Lurk, running some forgotten but critical applications on hardware systems passed their prime. We are now in the age of "Cloud Computing" yet there are still those who staff 24/7 Data Centers. It is some time passed the last (modern) Millennium.
