UpSnap on Ubuntu 24.04 LTS

Overview

UpSnap is a small, fast web application for powering the machines on your own network on and off. You register a device once with its MAC address, then wake it with a single click, put it to sleep, reboot it, or shut it down with a command you define. A live dashboard pings every registered device so the status you see is current, and cron style schedules turn the whole thing into unattended automation: a lab that powers itself on before the working day and shuts itself down after it. Wake on lan is built into virtually every business class network adapter, yet it goes unused because the magic packet has to originate on the same broadcast domain as the target machine. UpSnap closes that gap: one small always on host inside your network that holds the device list and sends the packets, with a browser interface and a per user permission model so you can hand someone the power button for one machine without giving them the rest of the estate. Optional discovery over a range you supply finds devices for you instead of typing MAC addresses by hand.

Common uses

• Wake a lab or build farm before the working day and shut it down on a schedule after
• Power on a workstation in a branch office or workshop before someone travels to it
• Give one person the power button for a single machine without handing over the whole estate
