Anubis is usually installed in such a case.

Not saying this is an option for you, only that I kept my forgejo instance private to avoid dealing with this AI crawler bullshit. I hope you find a good solution.

i “fixed” the problem of those fucking bots by blocking everyone except my country

You should limit the amount of storage available to a single service.

Also, set up Anubis or restrict access

I’ve searched the docs a bit and found this setting: https://forgejo.org/docs/latest/admin/config-cheat-sheet/#quota-subjects-list

It seems to be partially for your case, though I don’t see artifacts, but you could limit all of forgejo to like 5GB and probably be good.

Yeah, I put not protection in front of mine, aftering noticing bots were scanning code and did grab emails. Using Anibus for now, still looking at other alternatives.

Are you using anything to defend against bots?

Does it not require an account for that? I would open a feature request if it doesn’t, else it creates a denial-of-service attack.

For now I asked chatgtp to help me to implement a simple return 403 on bot user agent. I looked into my logs and collected the bot names which I saw. I know it won’t hold forever but for now it’s quite nice, I just added this file to /etc/nginx/conf.d/block_bots.conf and it gets run before all the vhosts and rejects all bots. The rest just goes normally to the vhosts. This way I don’t need to implement it in each vhost seperatelly.

Script for monitoring disk space in Linux

The script below is designed to monitor disk space usage on a specified server partition. Configurable parameters include the maximum allowable percentage of disk space usage (MAX), the e-mail address to receive alerts (EMAIL) and the target partition (PARTITION).

The script uses the df command to collect disk usage information and sends email alerts if the current usage exceeds the specified threshold

#!/bin/bash
# Script: ./df_guard.sh [config_file]

# Set the maximum allowed disk space usage percentage
MAX=90

# Set the email address to receive alerts
EMAIL=user@example.com

# Set the partition to monitor (change accordingly, e.g., /dev/sda1)
PARTITION=/dev/sda1

# Get the current disk usage percentage and related information
USAGE_INFO=$(df -h "$PARTITION" | awk 'NR==2 {print $5, $1, $2, $3, $4}' | tr '\n' ' ')
USAGE=$(echo "$USAGE_INFO" | awk '{print int($1)}') # Remove the percentage sign

if [ "$USAGE" -gt "$MAX" ]; then
# Send an email alert with detailed disk usage information
echo -e "Warning: Disk space usage on $PARTITION is $USAGE%.\n\nDisk Usage Information:\n$USAGE_INFO" | \
mail -s "Disk Space Alert on $HOSTNAME" "$EMAIL"
fi

Installation

sudo install -m 0755 df_guard.sh /usr/local/bin/df_guard.sh

Make the script executable:

sudo chmod +x /usr/local/bin/df_guard.sh
