IPbandit is a tool that protects you from malicious IP addresses and CIDR blocks (IPv4/IPv6).
IPbandit aggregates several blacklists created by the community. You can select your lists, add or delete them, and even create your own blacklists to block entire countries, for example.

It's an aggregation of lists of malicious IP addresses to integrate with your firewalls. Examples : Fortinet FortiGate, Palo Alto, pfSense, OPNsense, iptables, NFtables, etc...

Using the default lists, you'll already block approximately 300,000 malicious IP addresses.

Designed to improve the security of your critical servers. Secure your Linux infrastructure : RHEL, Centos, AlmaLinux, Rocky Linux, SUSE, openSUSE, Debian, Ubuntu, Alpine Linux, Gentoo, NixOS, Arch Linux and the others.

cd /opt/clemaxil/IPbandit
chmod +x IPbandit.sh extras/aggregator.sh extras/fail2ban.sh

cd /opt/clemaxil/IPbandit/
./IPbandit.sh --aggregator

crontab -e

nano /etc/crond.d/IPbandit

Add this line, and adjust time

30 05 * * * root nice -n 10 /opt/clemaxil/IPbandit/IPbandit.sh --aggregator >/dev/null 2>&1

With full options (see extras section)

30 05 * * * root nice -n 10 /opt/clemaxil/IPbandit/IPbandit.sh --fail2ban --aggregator >/dev/null 2>&1

After execution, you will find the generated files in IPbandit/list.d directory, which you can then use for your services.

• IPbandit_all.txt
• IPbandit_ipv4.txt
• IPbandit_ipv4_subnet.txt
• IPbandit_ipv6.txt
• IPbandit_ipv6_subnet.txt

Note: IPdeny offers free downloads of GEO IP address blocks by country. You can add a list of IP addresses from a country to this directory. https://www.ipdeny.com/ipblocks/

You can add your own lists to the extras/list.d directory. Important ! Name your files with the .list extension.

You can choose which lists to download by editing the IPbandit_custom.txt file.

You can retrieve the list of IPs detected by fail2ban on your machine.

The Ips will be written in the files extras/list.d/myfail2ban.list.\ This file will then be imported directly by IPbandit.

You can run the scriptextras/fail2ban.sh separately

cd /opt/clemaxil/IPbandit/extras/
./fail2ban.sh 

or with the IPbandit options.

cd /opt/clemaxil/IPbandit/
./IPbandit.sh --fail2ban
