Fail2ban Doctor

Super-Linter

This script is designed to manage fail2ban for SSH security and analyze authentication logs on a Linux system to provide insights into failed login attempts, IP addresses, and more.

Features

  • Check Failed Login Attempts: View the number of failed login attempts.
  • Top Login Attempts: Display top usernames of failed login attempts.
  • Failed Attempts by IP: Check failed login attempts by IP address.
  • View fail2ban Status: Check the status of fail2ban for SSH.
  • Disable SSH Root Login: Disable root login via SSH for enhanced security.
  • Top Countries: Determine top countries based on banned IP addresses. (GeoIP Lookup)
  • Blackhole blacklist: Use blackhole to create a huge list of bad IP addresses to ban.
  • Update blackhole blacklist: Update the blackhole blacklist every 30 days using cron.

I have a lot of ideas for this script, expect more features soon.

Usage

Note

Root access is required for full access to logs and SSH configuration. The script require geoiplookup and fail2ban. If not present, it offers to install them.

The script has been tested on Ubuntu 23.10 x86_64 only for now.
