HeartbeatSaver

HeartbeatSaver is a utility, bundled with fCraft 0.633+, that serves as a standalone heartbeat server. It runs separately from fCraft process and reads information from a file (HeartbeatData.txt). This allows your server to keep its uptime on Minecraft.net even when your fCraft server process needs to be restarted/shutdown.

When you disable fCraft's built-in heartbeat (from the Advanced tab of ConfigGUI, or by setting HeartbeatEnabled config key to "false"), fCraft will start writing heartbeatdata.txt to disk, in fCraft's working directory.

HeartbeatSaver only works as long as its external IP address is exactly same as your server's. That means it'll always work when ran from the same machine that fCraft is on, and it will usually work from another machine on the same LAN.

Usage

HeartbeatSaver "Path/To/heartbeatdata.txt"

heartbeatdata.txt format

Usually you don't need to mess with heartbeatdata.txt yourself. fCraft will generate this for you.
