rSync Files on Interval

Sync media to Raspberry Pi or any ARM SoC.

A recurring requirement for my IOT projects involves keeping a set of files synced with a central server. Many of these projects include media players, kiosk systems, or applications that need frequently updated configuration files, all while entirely unattended, and in most cases unreachable through firewalls. I have one project that alone has 2000+ devices pulling media continuously from an rsync server. Many of these devices are on doggy wifi networks.

Getting the unique serial number from a Raspberry Pi. cat /proc/cpuinfo | grep ^Serial | cut -d":" -f2 Example output: 00000000e215b4a2 An interesting use for this is “binding” software, encryption or other servcies to a specific Pi. Found this in a suggestion on the Stack Overflow question “Securing data on SD card Raspberry Pi”
