ServerControlPanel

ServerControlPanel is a simple web panel to stop/start a server.

It also provides the optional ability to trigger automatic restarts if the server crashes (or otherwise stops externally to the panel).

Status

The project is minimalist but fully functional and relatively clean.

Notes

• There is a password attempt flood prevention system. Too many invalid passwords from one IP in a short period of time will result in the user being blocked temporarily.

Setup

• Requires .NET 6.0 or higher.
• Designed to run on remote Linux servers.
• By default configured to open on port 8011.
• Meant to sit behind a proxy server (such as Apache).
• Strongly recommended that the external access point for the panel is HTTPS only.

Make folder config in the server directory, and within it add the following files:

• password_hash.txt - fill with a valid server password hash. Connect to the webserver at page /Home/HashGenerator to generate a hash. Please use a very long and generally strong password.
• status_check.sh - fill with a bash script that will output true if server is running, and false if not.
• stop.sh - fill with a bash script that will stop the server immediately.
• start.sh - fill with a bash script that will start the server immediately.
• restart.sh - fill with a bash script that will restart the server immediately.
• config.txt - for other configuration (see example).

Sample Scripts

Here are sample scripts for a simple screen-based server to be tracked.

status_check.sh:

#!/bin/bash

SCREEN_LIST=`screen -ls`

if [[ $SCREEN_LIST == *'screen_name'* ]]; then
    echo 'true'
else
    echo 'false'
fi

stop.sh:

#!/bin/bash

screen -S screen_name -X kill

start.sh:

#!/bin/bash

cd ~/my_server/
screen -dmS screen_name ./start.sh

restart.sh:

#!/bin/bash

./config/stop.sh
./config/start.sh

---

config.txt:

auto_check=true
check_rate=300
double_check=true

• auto_check: 'true' means check server status and start it if it's stopped (except when 'stop' was intentionally triggered on the panel) and restarts if so.
• check_rate: set to time (in seconds) between status checks.
• double_check: 'true' means two failed status checks in a row (with check_rate time in between) required to trigger a restart (to avoid accidentally triggering a new restart mid pre-existing restart).
