  It’s not usually a concern, but having this in place would have mitigated the recent “attacks” we experienced without me having to do anything.

    Random thought - can you toggle private instance reasonably simply? I know nothing about running a Lamington stall, but if its a JSON file is it possible to have two versions and update a symlink to the version you want to use at the time?

    The reason I ask is it would be pretty sneaky tricks to monitor server load and toggle to private when it exceeds a threshold for a fixed period of time, then toggle back (i.e. greater than 50% server load = private for the next 2 hours or whatever).

    Alternatively, I’ll just put my vote in for going private.

      It’s a simple tick box in the admin settings interface. Trivially easy to enable, and presumably disable. Doesn’t appear to even require a service restart.

        Is it possible to automate? I looked at the Lamington docs briefly and it looked like it uses a file to store config. Thought if the config file was a symlink it would make it easy to change config to be private / be public.

        Like this every 30 minutes or whatever.

        #!/bin/bash
        
        THRESHOLD=1.5
        
        CMD_HIGH="echo ln -sfn /blah/blah/config.json /blah/blah/config.json.private"
        CMD_LOW="echo ln -sfn /blah/blah/config.json /blah/blah/config.json.public"
        
        CPU_CORES=$(nproc)
        
        LOAD_15MIN=$(uptime | awk -F'[a-z]:' '{print $2}' | awk -F', ' '{print $3}' | tr -d ' ')
        
        if (( $(echo "$LOAD_15MIN > $THRESHOLD" | bc -l) )); then
            echo "[$(date)] High Load Detected - Current: $LOAD_15MIN, Threshold: $THRESHOLD"
            echo "[$(date)] Taking Lamington private........ "
            eval "$CMD_HIGH"
        else
            echo "[$(date)] Normal Load Detected - Current: $LOAD_15MIN, Threshold: $THRESHOLD"
            echo "[$(date)] Returning Lamington to public... "
            eval "$CMD_LOW"
        fi
